CDM Regulations and Asbestos: What Every UK Duty Holder Must Know

The impact of CDM on asbestos management in the UK is far-reaching — and if you’re involved in construction, refurbishment, or demolition, it directly affects you. The Construction Design and Management Regulations restructured how duty holders identify, manage, and control asbestos risks on site.

Get it wrong, and you’re looking at unlimited fines, prosecution, and — most critically — workers’ lives at risk. This post breaks down exactly how CDM intersects with asbestos obligations, who carries responsibility, and what practical steps you need to take to stay compliant.

What CDM Regulations Actually Changed for Asbestos Management

CDM 2015 didn’t just tweak the previous framework — it restructured accountability across the entire construction process. One of the most significant shifts was replacing the CDM Co-ordinator role with the Principal Designer, a change that moved asbestos risk planning firmly into the pre-construction phase.

Under the current framework, asbestos is no longer treated as an afterthought discovered mid-project. CDM requires duty holders to identify and account for asbestos hazards before a single wall is touched. This applies to demolition, strip-out, refurbishment, and even routine maintenance that disturbs building fabric.

The regulations also expanded the scope of notifiable work and tightened requirements around information sharing between clients, designers, and contractors. Everyone in the project chain now has a defined role in asbestos risk management — and ignorance of that role is not a defence.

The Duty to Manage Asbestos Under CDM

The duty to manage asbestos sits at the heart of how CDM interacts with the Control of Asbestos Regulations. These two regulatory frameworks work in parallel — CDM sets the project management structure, while the Control of Asbestos Regulations set the specific technical and procedural requirements for working with or near asbestos-containing materials (ACMs).

Under CDM, clients must ensure that any asbestos information relevant to the project is gathered and passed on to the Principal Designer and Principal Contractor before work begins. This means commissioning the right type of survey at the right stage — not scrambling for one when the skip is already outside.

The HSE’s guidance document HSG264 sets out the survey methodology that underpins this process. It defines the different survey types, sampling requirements, and the standard of reporting expected. Any survey used to satisfy CDM pre-construction obligations should align with HSG264.

What Must Be in the Pre-Construction Information Pack?

Clients are required to compile and distribute pre-construction information before work starts. Where asbestos is concerned, this pack must include:

• Results of any asbestos surveys carried out on the property
• The asbestos register, including locations, material condition, and risk ratings
• Details of any previously identified or removed ACMs
• Any known limitations of previous surveys
• Recommendations from the surveyor regarding further investigation

Failing to include this information — or handing over an outdated register — puts the client in breach of their CDM duties and potentially in breach of the Control of Asbestos Regulations too.

Which Asbestos Survey Do You Need Under CDM?

The type of survey required depends entirely on the nature of the work being planned. Getting this wrong is one of the most common compliance failures we encounter — particularly when clients commission a management survey and then proceed with full refurbishment work.

Management Surveys

A management survey is appropriate for properties in normal occupation where no major works are planned. It identifies the location and condition of ACMs that could be disturbed during routine maintenance or day-to-day activities, forming the basis of the asbestos register and management plan that building owners must maintain under the Control of Asbestos Regulations.

This survey type is not sufficient for refurbishment or demolition work. Using a management survey to satisfy CDM pre-construction requirements for intrusive work is a serious error that can expose clients and contractors to significant liability.

Refurbishment Surveys

Before any refurbishment, fit-out, or intrusive maintenance work, a refurbishment survey is required. This is an intrusive survey — it involves destructive inspection of the areas to be worked on to locate all ACMs that could be disturbed. The surveyed area must be unoccupied during the inspection.

Under CDM, the results of a refurbishment survey must be included in the pre-construction information pack. The Principal Designer uses this to inform the design and planning process, and the Principal Contractor uses it to develop the Construction Phase Plan.

Demolition Surveys

A demolition survey is the most thorough type available. It covers the entire structure and is required before any demolition work begins — every part of the building must be accessed and inspected, including areas that would normally remain undisturbed.

CDM places clear responsibility on the client to ensure this survey is completed and the results communicated to all relevant duty holders before demolition commences. Proceeding without one is not only a CDM breach — it is a criminal offence under the Control of Asbestos Regulations.

Roles and Responsibilities Under CDM for Asbestos

Understanding the full impact of CDM on asbestos management means understanding who carries what duty. The regulations are explicit, and each duty holder has obligations that cannot simply be delegated away.

Clients

The client — whether a commercial property owner, housing association, or local authority — carries the highest level of responsibility. They must ensure that asbestos surveys are commissioned from competent surveyors, that the results are included in pre-construction information, and that sufficient time and resource is allocated to manage asbestos safely before and during the project.

Clients must also ensure that any asbestos information discovered during the project is captured in the Health and Safety File at completion. This file must be handed over at the end of the project and retained for the lifetime of the building.

Principal Designers

The Principal Designer is responsible for planning, managing, and coordinating health and safety during the pre-construction phase. In practice, this means reviewing all asbestos survey data, flagging risks to the design team, and ensuring that design decisions minimise the likelihood of workers disturbing ACMs during construction.

Where asbestos is present, the Principal Designer should work with asbestos consultants to understand the scope of the risk and ensure it is communicated clearly in the pre-construction information. They also contribute to the Health and Safety File.

Principal Contractors

The Principal Contractor takes over responsibility for health and safety management during the construction phase. They must develop a Construction Phase Plan that addresses asbestos risks specifically — detailing how ACMs will be managed, who will carry out licensed removal works, and how air monitoring will be conducted.

Principal Contractors must also ensure that any subcontractors working near or with asbestos are appropriately trained and licensed, and that emergency procedures are in place if unexpected ACMs are discovered during work.

Contractors and Workers

All contractors must cooperate with the Principal Contractor’s asbestos management arrangements. Workers must be briefed on the location of known ACMs before starting work, and must stop immediately and report to the site manager if they suspect they have encountered asbestos during work.

There is no grey area here. Continuing to work after a suspected asbestos find — without assessment — is a direct breach of the Control of Asbestos Regulations and places workers at serious risk.

Asbestos Control Limits and Risk Registers

The Control of Asbestos Regulations set a control limit of 0.1 asbestos fibres per cubic centimetre of air, averaged over a four-hour period. This is a legal ceiling — not a target. Work must be planned to keep exposure as far below this limit as reasonably practicable.

Under CDM, asbestos risk registers must be maintained and kept current. A register that hasn’t been updated since the last survey, or that doesn’t reflect recent works, fails to meet the standard required.

Key elements of a compliant asbestos register include:

• Location of all identified ACMs, with floor plans or annotated drawings
• Material type and condition assessment for each ACM
• Risk rating based on likelihood of disturbance and fibre release potential
• Recommended management actions and timescales
• Record of any previous removal or encapsulation works
• Date of last survey and scheduled review date

Air monitoring results must be recorded and retained. Where licensed asbestos removal work is carried out, clearance air testing must be completed by an independent UKAS-accredited body before the area is reoccupied.

Enforcement and the Consequences of Non-Compliance

The HSE enforces CDM and the Control of Asbestos Regulations robustly. There is no upper limit on fines for asbestos-related offences, and custodial sentences have been handed down in cases involving serious breaches. The HSE can issue Improvement Notices, Prohibition Notices, and refer cases for prosecution — and they do.

Enforcement action is not limited to contractors. Clients who fail to commission appropriate surveys, provide adequate pre-construction information, or allocate sufficient resources for safe asbestos management have faced prosecution. The duty of care extends across the entire project hierarchy.

Beyond financial and criminal penalties, the reputational damage of an HSE investigation can be significant. Contracts can be lost, insurance can be affected, and directors can be personally liable where gross negligence is established.

Common CDM Asbestos Compliance Failures

The most frequent CDM asbestos compliance failures we encounter include:

• Using a management survey for refurbishment or demolition work
• Failing to include asbestos survey results in pre-construction information
• Not commissioning a survey at all for pre-2000 buildings
• Asbestos registers that are out of date or incomplete
• Unlicensed contractors carrying out licensable asbestos removal work
• Inadequate or absent air monitoring during and after removal
• Failure to update the Health and Safety File with asbestos information

Each of these failures creates direct legal exposure for the duty holder responsible. None of them are difficult to avoid with proper planning and competent advice.

Practical Steps for CDM Asbestos Compliance

Whether you’re a client, designer, or contractor, there are clear actions you can take to ensure your project handles asbestos correctly under CDM.

Before Work Begins

1. Establish whether the building was constructed before 2000 — if so, assume asbestos is present until proven otherwise
2. Commission the correct type of survey for the planned scope of work
3. Ensure the surveyor is competent and the survey aligns with HSG264
4. Include all survey results and the asbestos register in pre-construction information
5. Confirm that the Principal Designer has reviewed and incorporated asbestos risks into the design process

During Construction

1. Ensure the Construction Phase Plan addresses asbestos specifically
2. Brief all workers on known ACM locations before work starts
3. Engage only licensed contractors for licensable asbestos removal
4. Maintain ongoing air monitoring in areas where disturbance risk is elevated
5. Have a clear procedure for unexpected asbestos finds — stop, report, assess

At Project Completion

1. Ensure all asbestos removal certificates and air clearance certificates are retained
2. Update the asbestos register to reflect the current state of the building
3. Include all asbestos-related documentation in the Health and Safety File
4. Hand over the updated file to the client or building owner

CDM Asbestos Compliance Across the UK

CDM and asbestos obligations apply consistently across England, Scotland, Wales, and Northern Ireland — there is no regional variation in the core regulatory requirements. However, the practical challenges of compliance can vary depending on the age and type of building stock in a given area.

Older industrial and commercial buildings in major cities carry a particularly high likelihood of containing ACMs. If you’re undertaking construction or refurbishment work in a major urban centre, the probability of encountering asbestos is elevated — and your pre-construction planning should reflect that.

Supernova Asbestos Surveys operates nationwide. Whether you need an asbestos survey in London, an asbestos survey in Manchester, or an asbestos survey in Birmingham, our surveyors are experienced in the full range of CDM-compliant survey types and can turn results around quickly to keep your project on track.

Frequently Asked Questions

Does CDM apply to all construction projects involving asbestos?

CDM applies to virtually all construction work in the UK, including maintenance and refurbishment. Where a building may contain asbestos — typically any structure built before 2000 — CDM requires that asbestos risks are identified, assessed, and communicated before work begins. Even small projects are not exempt from the duty to manage asbestos safely.

Who is responsible for commissioning an asbestos survey under CDM?

The client holds primary responsibility for ensuring the correct asbestos survey is commissioned before work starts. They must provide the results to the Principal Designer and Principal Contractor as part of the pre-construction information. However, Principal Designers also have a duty to flag where asbestos information is missing or insufficient.

What is the difference between a management survey and a refurbishment survey under CDM?

A management survey is a non-intrusive inspection suitable for buildings in normal use — it is not appropriate for projects involving refurbishment or demolition. A refurbishment survey is an intrusive inspection of the specific areas to be worked on and is required under CDM before any refurbishment work begins. Using the wrong survey type is a common compliance failure and can expose clients and contractors to significant legal liability.

What happens if asbestos is discovered unexpectedly during construction?

Work must stop immediately in the affected area. The Principal Contractor must be notified, and a competent asbestos surveyor should assess the material before any further work proceeds. Under the Control of Asbestos Regulations, continuing to work after a suspected asbestos find without proper assessment is a criminal offence. The unexpected find must also be recorded and the asbestos register updated accordingly.

Can unlicensed contractors remove asbestos on a CDM project?

Only certain types of low-risk, non-licensable asbestos work can be carried out by unlicensed contractors — and even then, specific conditions apply. Most asbestos removal on construction sites involves licensable materials such as sprayed coatings, pipe lagging, or insulating board, which must be removed by a contractor holding a licence issued by the HSE. Engaging an unlicensed contractor for licensable work is a serious breach of both CDM and the Control of Asbestos Regulations.

Work With a Surveyor Who Understands CDM

The impact of CDM on asbestos management is significant — and the consequences of getting it wrong fall on clients, designers, and contractors alike. The good news is that compliance is straightforward when you work with the right people from the outset.

Supernova Asbestos Surveys has completed over 50,000 surveys across the UK. Our surveyors understand CDM obligations in detail and can advise on the correct survey type for your project, produce HSG264-compliant reports, and turn results around quickly to keep your programme on track.

What Is a CDM Assessment — and Why Does Asbestos Make It Far More Complex?

If you’re planning construction, refurbishment, or demolition work on any building constructed before 2000, a CDM assessment isn’t optional. The Construction (Design and Management) Regulations place clear legal duties on every party involved — from the client through to the principal contractor — and when asbestos enters the picture, those duties become significantly more demanding.

Asbestos remains the single largest cause of work-related deaths in the UK. Getting your CDM assessment right, and integrating asbestos management into it from the very start, is what separates a well-run project from a costly, dangerous, and potentially criminal one.

Understanding the CDM Assessment in Construction Projects

A CDM assessment is the process of identifying, evaluating, and managing health and safety risks across the full lifecycle of a construction project. Under the Construction (Design and Management) Regulations, duty holders must demonstrate that they have the competence and resources to manage risks on site — including pre-existing hazards within the structure itself.

For any building that may contain asbestos-containing materials (ACMs), the CDM assessment must address how those materials will be identified, managed, and — where necessary — removed before or during works. Failing to do this isn’t just a procedural oversight. It puts workers at direct risk of exposure to one of the most dangerous substances ever used in UK construction.

Who Is Responsible Under CDM?

Responsibility under CDM is shared, but it is also specific. Each duty holder has defined obligations, and asbestos management runs through all of them.

The Client

The client has an overarching duty to ensure the right people are appointed and that adequate pre-construction information is provided to the project team. This includes all known or suspected asbestos data for the site.

If that data doesn’t exist, the client is responsible for ensuring it is obtained before work begins. Commissioning a suitable asbestos survey is not something that can be delegated away or deferred.

The Principal Designer

The principal designer must coordinate health and safety during the design phase. That means ensuring asbestos risks are identified and communicated before anyone picks up a tool.

Asbestos management cannot be an afterthought bolted on once design decisions have already been made. If the principal designer doesn’t have current survey data to work from, they cannot fulfil this duty properly.

The Principal Contractor

The principal contractor takes on responsibility during the construction phase, ensuring all site workers are protected and that any asbestos work is carried out by appropriately licensed operatives. The construction phase plan must explicitly address asbestos — not just reference it in passing.

Why Asbestos Must Be Central to Your CDM Assessment

Asbestos doesn’t announce itself. It can be hidden inside floor tiles, pipe lagging, ceiling panels, spray coatings, and partition walls — often in materials that look entirely unremarkable. Without a proper survey completed before your CDM assessment is finalised, you’re effectively planning works around an unknown hazard.

The Control of Asbestos Regulations set out the legal framework for managing asbestos in non-domestic premises and during construction work. These regulations work alongside CDM duties rather than separately from them.

A thorough CDM assessment must reflect the findings of any asbestos surveys and set out clearly how ACMs will be managed throughout the project. Survey data isn’t just background information — it directly shapes site sequencing, contractor selection, and the construction phase plan.

The Pre-Construction Information Pack

One of the most important documents in any CDM-notifiable project is the pre-construction information pack. This should include all available data about the presence of asbestos on site — existing management surveys, previous removal records, and any known locations of ACMs.

If this information doesn’t exist, it needs to be generated before the project begins. That means commissioning the right type of asbestos survey for the scope of work planned — and doing so early enough that the findings can properly inform the project design and planning.

Choosing the Right Asbestos Survey for Your CDM Assessment

Not all asbestos surveys are the same, and choosing the wrong type can undermine your entire CDM assessment. The survey you need depends on what you’re planning to do with the building.

Management Surveys

A management survey is the baseline survey for any occupied or in-use building. It identifies ACMs that could be disturbed during normal occupancy and routine maintenance, and it’s legally required for most non-domestic premises.

For CDM purposes, it provides essential background information — but it is not sufficient on its own if intrusive works are planned. Management surveys are carried out with minimal disruption and without breaking into the building fabric, which means concealed materials can remain undetected.

Refurbishment Surveys

If your project involves any intrusive work — stripping out, altering the building fabric, or accessing voids and service ducts — you need a refurbishment survey covering the areas to be disturbed. This is a more invasive process: surveyors will access concealed areas, break into the building structure where necessary, and take samples from materials that a management survey wouldn’t touch.

The affected area must be vacated before a refurbishment survey takes place. The results will tell you exactly what ACMs are present in the zones where work is planned — information that is essential for your CDM assessment to be accurate and legally defensible.

Demolition Surveys

If the building is coming down entirely, a demolition survey is required. This is the most intrusive type of survey and must cover the entire structure. Every accessible area is inspected, sampled, and assessed before demolition work commences.

A demolition survey is a non-negotiable part of the CDM assessment process for any teardown project. Without it, you cannot safely plan the removal of hazardous materials, and you cannot legally proceed with demolition.

Integrating Survey Findings into Your CDM Documentation

Once your survey is complete, the findings need to be properly embedded into the CDM documentation — not just filed away. This is where many projects go wrong: survey reports get produced, but the implications for site planning, sequencing, and contractor briefing are never properly worked through.

Updating the Pre-Construction Information

Survey findings should be incorporated into the pre-construction information pack immediately. Every contractor tendering for or working on the project needs to understand what ACMs are present, where they are located, and what the management strategy is.

This information shapes how work is sequenced, what PPE is required, and which contractors are eligible to carry out specific tasks. Leaving it out creates gaps that can lead to accidental disturbance and serious legal exposure.

The Construction Phase Plan

The principal contractor’s construction phase plan must address asbestos management explicitly. This isn’t a box-ticking exercise — it needs to reflect the actual site conditions identified in the survey. The plan should include:

• The location of all identified ACMs on site
• The management strategy for each material — encapsulation, enclosure, or removal
• Details of any licensed asbestos removal work required before or during construction
• Emergency procedures in the event of accidental disturbance
• Air monitoring requirements and exposure control measures
• Arrangements for waste disposal in compliance with hazardous waste regulations

The Health and Safety File

At project completion, the health and safety file must be updated to reflect the current asbestos position on site. If ACMs have been removed, the file should confirm this with supporting documentation. If materials remain in situ and are being managed, their location and condition must be clearly recorded for future duty holders.

An accurate, up-to-date health and safety file is a legal requirement — and it protects everyone involved in future works on the building.

Licensed vs Non-Licensed Asbestos Work Under CDM

Not all asbestos work requires a licensed contractor, but understanding the distinction is critical for your CDM assessment. The Control of Asbestos Regulations categorise asbestos work into three tiers: licensed work, notifiable non-licensed work (NNLW), and non-licensed work.

Licensed work — which covers most work with asbestos insulation, asbestos insulation board, and asbestos coatings — can only be carried out by contractors holding a licence issued by the HSE. This work must be notified to the relevant enforcing authority at least 14 days before it begins, and health records for licensed asbestos workers must be retained for 40 years.

For your CDM assessment to be robust, you need to know which category applies to each ACM identified in your survey. This determines who can do the work, what notifications are required, and what medical surveillance obligations exist. Where asbestos removal is required, only appropriately licensed contractors should be engaged for licensable work.

The Role of Sample Analysis in Supporting Your CDM Assessment

Survey findings are only as reliable as the analytical data underpinning them. When surveyors take bulk samples from suspected ACMs, those samples must be analysed by a UKAS-accredited laboratory using polarised light microscopy to confirm the presence and type of asbestos fibres.

Accurate sample analysis is what converts visual suspicion into confirmed fact — and confirmed facts are what your CDM assessment must be built on. Relying on presumed ACMs rather than confirmed results introduces unnecessary uncertainty into your project planning and can lead to either over-specification or dangerous under-specification of controls.

Always ensure the laboratory used by your surveyor holds UKAS accreditation for asbestos analysis. This is a non-negotiable quality standard, not a preference.

Selecting a Competent Asbestos Surveyor

The quality of your CDM assessment is only as good as the survey data underpinning it. Choosing the right surveyor matters enormously — and the qualifications and accreditations to look for are well established.

Qualifications and Accreditation

Asbestos surveyors should hold the P402 qualification — the industry-standard certificate for asbestos surveying. This demonstrates that the individual has been assessed as competent to carry out surveys and interpret findings correctly.

The surveying organisation should hold UKAS accreditation for asbestos surveying and analysis. UKAS accreditation means the organisation has been independently assessed against internationally recognised standards — it’s the benchmark you should insist on. Always confirm that the reporting format aligns with the requirements of HSG264, the HSE’s guidance on asbestos surveying.

Independence and Objectivity

Your surveyor should be independent of any asbestos removal contractor. A surveyor with a commercial interest in finding — or not finding — asbestos cannot be relied upon to give you an objective assessment. This independence is fundamental to the integrity of your CDM assessment.

Always ask for evidence of previous survey experience on similar projects, and check that the surveying company carries appropriate professional indemnity insurance. These aren’t bureaucratic formalities — they’re practical protections for your project.

What Happens If Asbestos Is Discovered During Works?

Even with thorough pre-construction surveys, unexpected ACMs can be uncovered during works. This is more common than many clients expect — particularly in buildings where previous surveys were limited in scope or where concealed voids weren’t accessed.

When this happens, the correct response is immediate. Work in the affected area must stop. The area should be cordoned off and access restricted. A specialist surveyor must be called to assess the material before any further work proceeds.

Your construction phase plan should already contain a clear protocol for this scenario. If it doesn’t, that’s a gap in your CDM assessment that needs to be addressed before works begin — not after an incident has occurred. The principal contractor has a duty to ensure that all workers know what to do if they suspect they’ve encountered asbestos.

CDM Assessments Across Different Project Types

The specific asbestos surveying and management requirements within a CDM assessment vary depending on the nature and scale of the project. Understanding how they differ helps you plan and resource accordingly.

Refurbishment Projects

For refurbishment work, a targeted refurbishment survey covering the areas to be disturbed is the minimum requirement. The survey must be completed before intrusive works begin, and the findings must feed directly into the construction phase plan. If the scope of works expands during the project, the survey coverage must expand too.

Demolition Projects

Full demolition requires a whole-building demolition survey — no exceptions. The CDM assessment for a demolition project must account for the full range of ACMs present, the sequencing of removal works, and the selection of licensed contractors for any licensable materials. Demolition cannot legally commence until hazardous materials have been appropriately managed.

Maintenance and Minor Works

Even smaller projects that fall under CDM must consider asbestos. If a building has an existing asbestos management plan and register, this information should be reviewed and incorporated into the pre-construction information. If no register exists, one should be established before works begin.

Frequently Asked Questions

What is a CDM assessment and when is it required?

A CDM assessment is the process of identifying and managing health and safety risks across a construction project under the Construction (Design and Management) Regulations. It is required for virtually all construction, refurbishment, and demolition work, with additional notification requirements applying to larger or longer-duration projects. Asbestos management must be integrated into the CDM assessment for any building that may contain ACMs.

Do I need an asbestos survey before starting a CDM-notifiable project?

Yes. The client is required to provide pre-construction information to the project team, and this must include all known asbestos data for the site. If no survey exists, one must be commissioned before works begin. The type of survey required — management, refurbishment, or demolition — depends on the nature of the works planned.

What type of asbestos survey is needed for a refurbishment project?

Any project involving intrusive work to the building fabric requires a refurbishment survey covering the areas to be disturbed. This is a more invasive survey than a standard management survey and must be completed, with the affected area vacated, before intrusive works commence. The findings must be incorporated into the CDM documentation and construction phase plan.

Who can carry out licensed asbestos removal work on a CDM project?

Licensed asbestos removal work — which includes most work with asbestos insulation, asbestos insulation board, and asbestos coatings — can only be carried out by contractors holding a current HSE licence. This work must be notified to the relevant enforcing authority at least 14 days in advance. Your CDM assessment should identify which ACMs require licensed removal and ensure only appropriately licensed contractors are appointed for that work.

What should I do if asbestos is found unexpectedly during construction?

Work in the affected area must stop immediately. The area should be cordoned off and access restricted until a specialist surveyor has assessed the material. Your construction phase plan should already contain a protocol for this scenario. The principal contractor is responsible for ensuring all site workers know how to respond if they suspect they have encountered asbestos during works.

Why Every Builder Needs an Asbestos Survey Before Work Begins

Pick up a hammer in the wrong building and you could release fibres that kill. Asbestos remains the single largest cause of work-related deaths in the UK, and builders are among the most at-risk groups. Getting a proper asbestos survey for builders before any construction, refurbishment, or demolition work is not a box-ticking exercise — it is a legal requirement that protects your workers, your business, and your reputation.

Whether you are a sole trader fitting a kitchen or a principal contractor managing a multi-site development, the rules apply to you. This post breaks down exactly what you need to know.

What Is an Asbestos Survey and Why Do Builders Need One?

An asbestos survey is a structured inspection of a building carried out by a qualified surveyor to identify the presence, location, condition, and extent of any asbestos-containing materials (ACMs). For builders, it answers a critical question before work starts: is there anything in this building that could kill my workforce?

Any building constructed or refurbished before the year 2000 may contain asbestos. That covers an enormous proportion of the UK’s housing stock and commercial property. Textured coatings, insulation boards, floor tiles, pipe lagging, roof sheets — asbestos was used in hundreds of building products, and it does not always look the way people expect.

Without a survey, you are working blind. Disturbing asbestos without knowing it is there is how workers end up inhaling fibres that cause mesothelioma, asbestosis, and lung cancer — diseases that can take decades to develop but are invariably fatal.

The Two Types of Survey Builders Will Encounter

Not all surveys are the same, and choosing the wrong type can leave you legally exposed. There are two main survey types relevant to construction work.

Management Survey

A management survey is the standard survey required for the routine management of a building. It identifies ACMs that could be disturbed during normal occupancy and day-to-day maintenance. This survey is typically required by the building owner or dutyholder and should be available to any contractor working on the premises.

As a builder, you should always ask for the management survey register before starting work. If the client cannot produce one for a pre-2000 building, that is a serious red flag — and you may need to arrange a survey yourself before proceeding.

Refurbishment and Demolition Survey

If your work involves breaking into the fabric of a building — opening walls, lifting floors, removing ceilings, altering structural elements — a management survey is not sufficient. You need a demolition survey, more formally known as a refurbishment and demolition survey.

This is a far more intrusive inspection. The surveyor will access voids, break into surfaces, and check areas that a management survey would leave undisturbed. The area being surveyed must be vacated during the inspection. The goal is to locate every ACM that could be disturbed by the planned works — and that means getting into every corner of the affected area.

This survey is a legal requirement under the Control of Asbestos Regulations before any notifiable refurbishment or demolition work begins. There are no exceptions.

Your Legal Duties as a Builder Under UK Regulations

Two sets of regulations govern how builders must handle asbestos. Understanding both is essential — ignorance is not a defence, and the penalties for non-compliance are severe.

The Control of Asbestos Regulations

The Control of Asbestos Regulations impose a duty to manage asbestos on those responsible for non-domestic premises, and place strict requirements on anyone carrying out work where asbestos may be present. Key obligations for builders include:

• Identifying whether ACMs are present before work starts
• Ensuring a suitable survey has been carried out by a competent person
• Assessing the risk from any ACMs identified
• Preventing or adequately controlling exposure to asbestos fibres
• Ensuring workers who may disturb asbestos are trained to the appropriate level
• Using licensed contractors for licensable asbestos work
• Notifying the HSE before licensable asbestos work begins

The HSE’s guidance document HSG264 sets out in detail how surveys should be planned, conducted, and reported. Any surveyor you commission should be working to this standard.

Construction (Design and Management) Regulations — CDM

CDM regulations place duties on all parties in a construction project to manage health and safety risks, including asbestos. Under CDM, the principal designer must take account of any pre-construction information — which includes asbestos survey data — when developing the design and the construction phase plan.

The principal contractor must ensure that asbestos information is communicated to all relevant workers on site. If a refurbishment and demolition survey has not been carried out, the principal contractor should not allow intrusive work to begin. Asbestos surveys are pre-construction information, and failing to obtain and act on them is a clear CDM breach.

Under CDM, every duty holder — client, principal designer, principal contractor, and contractor — has a role to play. Asbestos management is not solely the client’s problem. If you are on site and you know the risks have not been properly assessed, you have a duty to raise it.

What Happens If Asbestos Is Found During Building Work?

Even with a thorough survey, unexpected finds do happen — particularly in complex or heavily altered buildings. Knowing what to do when this occurs can be the difference between a managed incident and a major enforcement action.

Stop Work Immediately

If a worker suspects they have disturbed asbestos, work in that area must stop immediately. Do not attempt to clean up the material or continue working around it. Evacuate the area and prevent others from entering.

Isolate the Area

Seal off the affected area as effectively as possible. This limits the spread of any fibres and protects other workers on site. Keep a record of who was in the area at the time of the find and whether they may have been exposed.

Get the Material Tested

Do not assume the material is or is not asbestos based on appearance alone. Arrange for a sample to be taken by a qualified surveyor and tested by a UKAS-accredited laboratory. Only once the results confirm the material’s identity can an informed decision be made about next steps.

Arrange Licensed Removal If Required

If the material is confirmed as asbestos and the work required to remove or manage it falls within the licensable category, you must engage a licensed asbestos removal contractor. Asbestos removal of licensable materials by unlicensed operatives is a criminal offence. Do not cut corners here — the consequences for workers’ health and for your business are too serious.

Choosing a Competent Asbestos Surveyor

The quality of your asbestos survey is only as good as the person carrying it out. HSG264 is clear that surveys must be conducted by competent surveyors with the appropriate qualifications, experience, and quality assurance systems. Here is what to look for:

• P402 qualification — issued by the British Occupational Hygiene Society (BOHS), this is the recognised qualification for asbestos surveyors in the UK
• UKAS accreditation — the surveying organisation should hold accreditation from the United Kingdom Accreditation Service, demonstrating that their processes meet the required standard
• Laboratory accreditation — samples should be analysed by a UKAS-accredited laboratory, not just any testing facility
• Clear, detailed reports — the survey report should include floor plans, photographs, sample locations, material condition assessments, and a risk priority rating for each ACM identified
• Adequate sampling — HSG264 specifies minimum sampling requirements; a surveyor taking too few samples is not providing a thorough service

Always ask for evidence of qualifications and accreditation before commissioning a survey. A cheap survey that misses ACMs is not a bargain — it is a liability.

Reading and Using the Survey Report on Site

Receiving the survey report is not the end of the process — it is the beginning of your asbestos management obligations on that project. Here is how to use it effectively:

1. Review the register — check every ACM listed, its location, condition, and risk rating before planning your work sequence
2. Share with all relevant parties — subcontractors, site managers, and any specialist trades need to know where ACMs are located before they start work
3. Update the construction phase plan — the asbestos information should be reflected in the CDM construction phase plan, including how ACMs will be managed or removed
4. Arrange removal in advance — where ACMs need to be removed before work can proceed, schedule this before the main works begin, not as an afterthought
5. Keep the report on site — the survey report should be accessible on site throughout the project, not filed away in an office

Training Requirements for Construction Workers

Every worker who could encounter asbestos during their work must receive appropriate training. The level of training required depends on the nature of the work:

• Asbestos awareness training — required for all workers who could inadvertently disturb asbestos during their normal work. This includes general builders, electricians, plumbers, and joiners working in pre-2000 buildings
• Non-licensed work training — required for workers carrying out non-licensable asbestos work, such as removing small amounts of asbestos cement or textured coatings
• Licensed contractor training — required for workers employed by licensed asbestos removal contractors carrying out licensable work

Training must be refreshed regularly. Keeping records of who has been trained and when is both good practice and a requirement under the Control of Asbestos Regulations.

Frequently Asked Questions

Do I need an asbestos survey before starting building work?

Yes — if the building was constructed or refurbished before 2000, an asbestos survey is required before any work that could disturb the building fabric. For intrusive work such as refurbishment or demolition, a refurbishment and demolition survey is a legal requirement under the Control of Asbestos Regulations. A management survey alone is not sufficient for this type of work.

Who is responsible for commissioning the asbestos survey on a construction project?

Under CDM regulations, the client has a duty to provide pre-construction information — including asbestos survey data — to the principal designer and principal contractor. However, if no survey exists or it is inadequate, the principal contractor should not allow intrusive work to begin. In practice, responsibility is shared across the project team, and all parties should ensure the information is in place before work starts.

What is the difference between a management survey and a refurbishment and demolition survey?

A management survey is designed for the ongoing management of a building and identifies ACMs that could be disturbed during normal maintenance. A refurbishment and demolition survey is a more intrusive inspection required before any work that will disturb the building fabric. It involves accessing voids and breaking into surfaces to locate all ACMs in the affected area. For construction work, the refurbishment and demolition survey is almost always the appropriate type.

What should I do if we find suspected asbestos during building work?

Stop work in the affected area immediately, isolate the area, and prevent other workers from entering. Do not attempt to clean up or remove the material. Arrange for a qualified surveyor to take a sample and have it tested by a UKAS-accredited laboratory. If the material is confirmed as asbestos and licensable removal is required, engage a licensed asbestos removal contractor before work resumes.

How quickly can Supernova Asbestos Surveys carry out a survey for a construction project?

How Much Do Asbestos Consultants Make in the UK?

Asbestos consultancy is one of the most specialised and consistently in-demand professions within the UK’s construction and health and safety sector. If you’re weighing up a career in this field — or you’re a property manager trying to understand what you’re actually paying for when you commission a survey — knowing how much asbestos consultants make in the UK is a genuinely useful starting point.

The answer isn’t a single figure. Earnings vary considerably depending on experience, qualifications, employer type, and location. But the profession consistently rewards those who invest in proper training and accreditation, and demand for qualified professionals shows no sign of weakening.

What Does an Asbestos Consultant Actually Do?

Before looking at the numbers, it’s worth being precise about what the role involves. Asbestos consultants are specialists who advise organisations on how to identify, manage, and safely deal with asbestos-containing materials (ACMs) in buildings.

Their day-to-day work typically includes:

• Conducting asbestos management surveys and refurbishment surveys across commercial, industrial, and residential properties
• Carrying out demolition surveys prior to structural works
• Collecting and submitting bulk samples for laboratory analysis
• Preparing asbestos management plans for duty holders
• Advising on compliance with the Control of Asbestos Regulations and HSE guidance, including HSG264
• Overseeing or auditing licensed asbestos removal contractors
• Providing training, risk assessments, and written reports to property owners, landlords, and contractors

It’s a role that carries genuine legal weight. Poor advice or missed asbestos can result in serious harm to workers and the public, which is why the profession is tightly regulated and well-compensated at senior levels.

How Much Do Asbestos Consultants Make in the UK? A Salary Breakdown

Salaries in asbestos consultancy follow a clear progression tied to experience and qualifications. Here’s a realistic picture of what you can expect at each career stage.

Entry-Level Asbestos Surveyors

Those just starting out — typically as trainee asbestos surveyors or analysts — can expect to earn in the region of £22,000 to £28,000 per year. At this stage, most are working towards their P402 (buildings surveys and bulk sampling) or P403/P404 qualifications under the British Occupational Hygiene Society (BOHS) proficiency scheme.

Entry-level roles often involve working under supervision, assisting on surveys, and building the practical skills needed to work safely with ACMs on site. It’s a hands-on apprenticeship in all but name, and the learning curve is steep.

Mid-Level Asbestos Consultants

With two to five years of experience and relevant BOHS qualifications, a consultant can typically earn between £30,000 and £42,000 per year. At this level, professionals are usually conducting surveys independently, writing detailed compliance reports, and providing advice directly to clients.

Many mid-level consultants hold the BOHS P402 and may also be working towards or holding the W504 (air monitoring) or the higher-level Certificate of Competence in Asbestos (COCA) qualification. This is the stage where specialist sector experience starts to make a meaningful difference to earning potential.

Senior Asbestos Consultants and Project Managers

Senior consultants and project managers with significant experience and a strong qualifications portfolio can earn between £45,000 and £60,000 per year. These roles typically involve managing teams of surveyors, handling major commercial contracts, and advising on complex refurbishment or demolition projects.

At this level, professionals often hold the BOHS Faculty of Occupational Hygiene (FOH) diploma or are Registered Members of the Faculty of Occupational Hygiene (RFOH). Direct liaison with the HSE and senior client stakeholders is routine.

Freelance and Self-Employed Asbestos Consultants

Self-employed consultants who have built a solid client base can earn considerably more than their employed counterparts. Day rates for experienced freelance asbestos consultants typically range from £300 to £600 per day, depending on the complexity of the work and the region.

Annualised, a busy freelance consultant working consistently could earn well in excess of £70,000 to £80,000. That said, this comes with the usual considerations around professional indemnity insurance, business overheads, and periods of lower demand — factors that employed consultants don’t need to manage directly.

How Does Location Affect Asbestos Consultant Salaries?

Location plays a meaningful role in earnings across most professional sectors in the UK, and asbestos consultancy is no different. Demand is highest in urban areas with large volumes of older commercial and residential property stock — precisely because so much of that stock contains ACMs.

Consultants working in London and the South East typically command a salary premium of 10–20% above the national average, reflecting both higher living costs and greater demand. If you need an asbestos survey in London, you’ll find that projects in the capital often involve complex commercial premises, listed buildings, or large residential blocks — work that requires experienced professionals and commands higher fees.

Outside London, cities with significant industrial and commercial property portfolios — including Manchester, Birmingham, Leeds, and Glasgow — generate strong, consistent demand. The sheer volume of pre-2000 commercial and industrial stock across these cities supports healthy consultant workloads and competitive salaries.

Rural and lower-demand areas may see slightly lower base salaries, though the rise of remote report writing and national surveying firms means geography is less of a barrier to earning potential than it once was.

What Qualifications Do You Need to Become an Asbestos Consultant?

Qualifications are the single biggest driver of earning potential in this profession. The UK has a well-established competency framework for asbestos professionals, built around the BOHS proficiency modules and the requirements set out in HSG264 and the Control of Asbestos Regulations.

Core BOHS Qualifications

The most widely recognised qualifications for asbestos surveyors and consultants are:

• P402 — Buildings surveys and bulk sampling for asbestos
• P403 — Asbestos fibre counting
• P404 — Air monitoring and clearance testing
• P405 — Management of asbestos in buildings
• W504 — Air monitoring for asbestos

The P405 qualification is particularly closely associated with consultancy roles, as it covers the management and advisory aspects of the profession rather than purely practical survey work. Consultants advising duty holders on their legal obligations under the Control of Asbestos Regulations are expected to hold this or an equivalent qualification.

UKAS Accreditation and Professional Body Membership

Many employers and clients look for consultants who work within UKAS-accredited organisations. The United Kingdom Accreditation Service (UKAS) accredits inspection bodies and testing laboratories under ISO standards, providing independent assurance of competence.

Membership of bodies such as the Asbestos Removal Contractors Association (ARCA) or the Asbestos Testing and Consultancy Association (ATaC) can also strengthen a consultant’s professional profile and support higher earning potential. These affiliations signal credibility to clients who may not be familiar with the technical detail of asbestos qualifications.

What Factors Push Asbestos Consultant Salaries Higher?

Beyond qualifications and location, several other factors influence how much an asbestos consultant earns in the UK. Understanding these can help both consultants planning their career development and clients understanding what drives the fees they pay.

Specialist Sector Experience

Consultants who develop expertise in specific sectors — such as healthcare, education, rail, or the nuclear industry — often command premium rates. These environments involve complex compliance requirements, higher risk profiles, and a greater need for specialist knowledge that generalist surveyors simply can’t provide.

Employer Type

Salaries vary depending on whether a consultant works for a specialist asbestos consultancy, a large environmental services company, a facilities management firm, or as an in-house consultant for a major property owner or public sector body.

Large national consultancies and environmental services firms often offer structured salary bands, pension contributions, and company vehicles — which can make the total package considerably more valuable than the base salary figure alone.

Management and Business Development Responsibilities

Consultants who take on team management, client relationship management, or business development responsibilities alongside their technical work typically earn at the higher end of the salary range. The ability to win and retain contracts is highly valued in this commercially competitive sector.

Additional Technical Skills

Consultants who can offer additional services — such as asbestos testing, air monitoring, clearance testing, or project management oversight of removal works — are more versatile and therefore more valuable to both employers and clients. Breadth of capability translates directly into higher earning potential.

Is Asbestos Consultancy a Good Career Choice?

From a career perspective, asbestos consultancy has a great deal to recommend it. Demand for qualified professionals remains consistently strong because the regulatory framework requires ongoing asbestos management across millions of pre-2000 properties throughout the UK.

The Control of Asbestos Regulations place a legal duty on those responsible for non-domestic premises to manage asbestos risks. This duty doesn’t disappear — it generates a continuous need for surveys, management plans, and expert advice. Every commercial building owner, local authority, school, hospital, and landlord with pre-2000 property stock is a potential client.

The profession also has a clear ethical dimension. Mesothelioma and other asbestos-related diseases continue to claim thousands of lives in the UK every year. Consultants who do their job well directly contribute to protecting workers and building occupants from a genuinely deadly hazard.

For those considering entry into the field, the career path is accessible. Many start as trainee surveyors with no prior asbestos experience, progressing through on-the-job learning and structured BOHS qualifications over two to four years. The investment in training pays back quickly once the core qualifications are in place.

What Does an Asbestos Survey Actually Cost a Client?

Understanding consultant earnings also means understanding the commercial context — what clients pay for asbestos services, and how that revenue supports the profession.

A straightforward residential management survey for a small property typically starts from around £250 plus VAT. Larger commercial or industrial premises, refurbishment surveys, or multi-site contracts will naturally cost considerably more, reflecting the time, expertise, and laboratory analysis involved.

Clients who want a preliminary indication of whether ACMs are present can use an asbestos testing kit for initial bulk sampling. However, a professional survey remains the appropriate and legally compliant route for duty holders under HSG264 — a testing kit is a useful tool, but it doesn’t replace a qualified consultant’s assessment.

The fees charged by consultancies reflect the cost of employing qualified professionals, maintaining UKAS accreditation, investing in laboratory analysis, and producing detailed written reports that meet regulatory requirements. When you understand the expertise involved, the pricing makes complete sense.

The Range of Services That Drive Consultant Workloads

Asbestos consultants rarely work on a single type of project. The breadth of services required across different property types and project stages means that experienced professionals are rarely short of work.

A refurbishment survey is required before any intrusive works begin on a building where ACMs may be disturbed. These surveys are more invasive than management surveys and require a higher level of expertise to plan and execute safely.

For properties approaching demolition, a full demolition survey must be completed to locate all ACMs before any structural works commence. These are among the most technically demanding survey types and command correspondingly higher fees.

On the analytical side, asbestos testing — including bulk sample analysis and air monitoring — forms a core part of many consultants’ workloads. The ability to interpret laboratory results and translate them into clear client advice is a skill that takes time to develop and is well rewarded.

Taken together, the variety of survey types, analytical services, management planning, and compliance advice means that a well-qualified consultant can build a genuinely varied and stimulating career — while earning a salary that reflects the seriousness of the work.

What Property Managers Should Know About Consultant Fees

If you’re a property manager or duty holder commissioning asbestos services, understanding what drives consultant earnings helps you assess whether you’re getting value for money — and why the cheapest quote isn’t always the right choice.

Qualified asbestos consultants carry significant professional responsibility. Their reports inform legal compliance decisions, guide contractor briefings, and protect building occupants. A report produced by an under-qualified or under-resourced consultant creates risk for everyone involved — including you as the duty holder.

When evaluating quotes, look for evidence of BOHS-qualified surveyors, UKAS accreditation, clear reporting standards, and professional indemnity insurance. These aren’t optional extras — they’re the baseline for a service that genuinely protects your legal position and the safety of those who use your building.

The fees you pay support a profession that requires years of training, ongoing CPD, regulatory compliance, and specialist equipment. That context matters when comparing quotes across providers.

Frequently Asked Questions

How much does an entry-level asbestos surveyor earn in the UK?

Entry-level asbestos surveyors typically earn between £22,000 and £28,000 per year. At this stage, most are working towards their BOHS P402 qualification and gaining practical experience under supervision on live survey projects.

Can asbestos consultants earn more by going freelance?

Yes. Experienced freelance asbestos consultants typically charge day rates of £300 to £600, which can translate to annual earnings well above £70,000 for those with a consistent client base. However, self-employment brings additional costs including professional indemnity insurance and periods of variable demand.

What qualifications do asbestos consultants need in the UK?

The core qualifications are delivered through the BOHS proficiency scheme. The P402 covers buildings surveys and bulk sampling, while the P405 covers management of asbestos in buildings — the most directly relevant qualification for consultancy roles. Senior consultants often hold the BOHS Faculty of Occupational Hygiene diploma or equivalent.

Does location affect how much asbestos consultants earn?

Yes, meaningfully. Consultants based in London and the South East typically earn 10–20% above the national average, reflecting higher demand and living costs. Major cities such as Manchester, Birmingham, and Leeds also generate strong demand and competitive salaries, particularly given their large volumes of pre-2000 commercial and industrial property.

What types of asbestos surveys generate the most work for consultants?

Management surveys, refurbishment surveys, and demolition surveys are the three main survey types and together account for the majority of consultant workloads. Air monitoring, clearance testing, and asbestos management planning also generate significant ongoing work, particularly for consultants working with large commercial property portfolios or public sector clients.

Asbestos Compliance Under CDM: What Every Dutyholder Needs to Know

Asbestos compliance isn’t optional — it’s a legal obligation that sits at the heart of construction, refurbishment, and property management across the UK. If your building was constructed before 2000, there’s a real chance asbestos-containing materials (ACMs) are present, and the law is unambiguous about what you must do.

Get it wrong and you’re looking at unlimited fines, prosecution, and in serious cases, imprisonment. This post unpacks the legal framework, the duties placed on each party, and the practical steps that keep your project — and your people — on the right side of the law.

The Legal Framework Behind Asbestos Compliance in the UK

Two sets of regulations form the backbone of asbestos compliance in the UK construction sector. Understanding how they interact is essential for anyone involved in building work.

Control of Asbestos Regulations

The Control of Asbestos Regulations establish the core duty to manage asbestos in non-domestic premises. They require dutyholders to identify ACMs, assess their condition, and produce a written management plan that is reviewed regularly.

The regulations also set out who can carry out different types of asbestos work. Licensed contractors are required for the highest-risk activities — including work on sprayed coatings, lagging, and certain insulation boards. Notifiable non-licensed work (NNLW) and non-licensed work each carry their own requirements around supervision, training, and record-keeping.

Crucially, the regulations require that information about ACMs is shared with anyone who might disturb them — including the emergency services. Local fire stations need to know where asbestos is located in buildings on their patch. This isn’t a box-ticking exercise; it protects firefighters during incidents.

Construction (Design and Management) Regulations

The Construction (Design and Management) Regulations — commonly known as CDM — place duties on clients, principal designers, principal contractors, and all contractors on a project. Asbestos is explicitly relevant throughout the CDM framework.

Under CDM, the pre-construction phase must address existing hazards in the structure — and asbestos is one of the most significant of those hazards. The pre-construction information pack must include any asbestos survey findings.

The health and safety file, handed to the client at project completion, must record the location and condition of any remaining ACMs. CDM applies to virtually all construction work, including maintenance and refurbishment — not just large commercial projects. Even domestic clients are covered in certain circumstances.

Who Is Responsible for Asbestos Compliance?

One of the most common sources of confusion is understanding where responsibility sits. CDM creates a layered duty structure, and asbestos compliance runs through every level of it.

The Client

The client — whether a commercial property owner, housing association, or local authority — carries significant responsibility. Before any construction or refurbishment work begins, the client must ensure that a suitable asbestos survey has been carried out and that the findings are passed on to designers and contractors.

Clients must also ensure that a construction phase plan is in place before work starts, and that the principal designer and principal contractor are fulfilling their duties. Selecting competent contractors isn’t just good practice — it’s a legal requirement.

The Principal Designer

The principal designer is responsible for planning, managing, and coordinating health and safety during the pre-construction phase. This includes identifying asbestos risks from existing survey data and ensuring that design decisions don’t inadvertently increase exposure risk.

If the survey data is incomplete or outdated, the principal designer should flag this to the client and ensure a further survey is commissioned before design work progresses. Designing around a hazard you haven’t fully identified isn’t compliance — it’s a liability.

The Principal Contractor

The principal contractor takes over coordination during the construction phase. They must ensure that the construction phase plan addresses asbestos risks specifically, that all contractors working on site are aware of the location of ACMs, and that any licensed removal is carried out before intrusive work begins.

The principal contractor is also responsible for ensuring that workers have received appropriate asbestos awareness training — not just licensed removal operatives, but any worker whose activities might bring them into contact with ACMs.

Contractors and Workers

Every contractor working on a pre-2000 building has a duty not to proceed if they encounter a suspected ACM without following the correct procedures. Workers must be trained to recognise materials that may contain asbestos and to stop work and report immediately if they suspect they’ve disturbed one.

This is where asbestos awareness training earns its keep. It’s not about turning every tradesperson into an asbestos specialist — it’s about ensuring no one accidentally drills into a ceiling tile or cuts through an insulated pipe without understanding the risk.

Surveys: The Foundation of Asbestos Compliance

You cannot manage what you haven’t identified. Surveys are the starting point for asbestos compliance, and choosing the right type of survey for the situation is critical.

Management Surveys

A management survey is the standard survey required for the ongoing management of ACMs in a building that is in normal occupation and use. It identifies materials that could be damaged or disturbed during everyday activities and assesses their condition, feeding directly into the asbestos register and management plan.

For non-domestic premises, having an up-to-date management survey isn’t optional — it’s a legal requirement under the duty to manage. If you don’t have one in place, you’re already non-compliant.

Refurbishment and Demolition Surveys

Where work is planned that will disturb the fabric of a building — whether that’s a kitchen refit, a rewiring project, or a full demolition — a demolition survey is required. This is a more intrusive survey that involves accessing areas not normally disturbed, including voids, risers, and structural elements.

A refurbishment and demolition (R&D) survey must be completed in the areas to be disturbed before any work starts. Carrying out intrusive work without one is one of the most common compliance failures — and one of the most dangerous.

HSG264, the HSE’s guidance document on asbestos surveys, sets out in detail the methodology for both survey types and the standard to which they must be conducted. It’s the definitive reference point for anyone commissioning or carrying out survey work.

Practical Steps for Asbestos Compliance on Construction Projects

Compliance doesn’t happen by accident. Here’s a practical sequence that applies to most construction and refurbishment projects involving pre-2000 buildings:

1. Commission the right survey early. Don’t wait until the project is about to start. Survey findings may affect the design, the programme, and the budget. Identify this at the feasibility stage.
2. Include survey findings in pre-construction information. The client must pass this information to the principal designer and all tendering contractors. It should not be buried in an appendix — it needs to be clearly communicated.
3. Address asbestos in the construction phase plan. The plan must specifically address how ACMs will be managed, who is responsible, and what procedures apply if unexpected ACMs are encountered.
4. Appoint a licensed contractor for licensable work. Check that the contractor holds a current HSE asbestos licence. Don’t assume — verify. Licence details are publicly available on the HSE website.
5. Ensure removal precedes intrusive work. Licensed removal must be completed and a four-stage clearance procedure — including air testing — must be passed before other trades move in.
6. Update the health and safety file. At project completion, the file must record the location and condition of any ACMs that remain in the structure.
7. Maintain the asbestos register. The register is a live document. Any work that disturbs or removes ACMs must be recorded and the register updated accordingly.

Training: A Non-Negotiable Requirement

Asbestos awareness training is required under the Control of Asbestos Regulations for anyone liable to disturb ACMs during their work. This covers a wide range of trades — electricians, plumbers, carpenters, gas engineers, and general maintenance workers are all included.

Training must be relevant to the work the individual carries out. It should cover:

• The properties of asbestos and its effects on health
• The types of materials likely to contain asbestos and where they’re found
• How to avoid the risk of exposure
• The correct action to take if ACMs are encountered unexpectedly
• Emergency procedures

Training records must be maintained, and refresher training should be provided regularly. Annual refreshers are considered best practice and are increasingly expected by principal contractors and clients as a condition of engagement.

The Consequences of Getting Asbestos Compliance Wrong

The HSE takes asbestos non-compliance seriously, and enforcement action is not rare. Inspectors have the power to issue improvement notices, prohibition notices, and to prosecute. The courts have the power to impose unlimited fines and custodial sentences.

Beyond the criminal consequences, non-compliance carries significant civil liability. If a worker develops an asbestos-related disease as a result of exposure on your site or in your building, the financial and reputational consequences can be severe and long-lasting.

Common enforcement triggers include:

• Carrying out licensable work without a licence
• Failing to notify the HSE of licensable work (required at least 14 days in advance)
• Inadequate or absent asbestos surveys before refurbishment
• Failure to provide asbestos awareness training
• Inadequate air monitoring during and after removal
• Failure to maintain an asbestos register in a non-domestic building

The HSE publishes details of prosecutions and enforcement notices. Being listed is not just a legal problem — it’s a reputational one that can affect your ability to win contracts and retain clients.

Asbestos Removal: When Management Isn’t Enough

Not all ACMs need to be removed. In many cases, material in good condition and not at risk of disturbance is best left in place and managed. However, when the condition deteriorates, when refurbishment work requires disturbance, or when a building is being demolished, asbestos removal becomes necessary.

Removal must be carried out by a licensed contractor for the majority of ACMs. The work area must be enclosed and under negative pressure, with decontamination facilities in place. Air monitoring must be conducted throughout, and a four-stage clearance — including a thorough visual inspection and air testing — must be passed before the enclosure is dismantled.

The waste must be double-bagged in UN-approved sacks, labelled correctly, and disposed of at a licensed facility. Documentation of disposal — a consignment note — must be retained. This paperwork isn’t optional; it forms part of the audit trail that demonstrates compliance.

Asbestos Compliance Across the UK: Regional Coverage

Asbestos compliance obligations are consistent across England, Scotland, Wales, and Northern Ireland — the regulatory framework applies equally regardless of location. What does vary is the local stock of pre-2000 buildings, the mix of property types, and the speed at which surveys and remediation can be mobilised.

In major urban centres, the density of older commercial and industrial stock means asbestos compliance is a daily operational reality for property managers and contractors. Supernova Asbestos Surveys operates nationally, with established capacity in key cities and regions.

If you’re based in the capital, our team carries out asbestos survey London work across all property types, from Victorian terraces to post-war commercial blocks. For clients in the North West, we provide a full asbestos survey Manchester service covering both management and refurbishment and demolition surveys. In the Midlands, our asbestos survey Birmingham team works with local authorities, housing associations, contractors, and private clients.

Wherever your project is located, the same standards apply — and the same consequences follow if those standards aren’t met.

Maintaining Asbestos Compliance Over Time

Asbestos compliance isn’t a one-time task. It’s an ongoing obligation that requires regular review and active management. An asbestos register produced five years ago and never revisited is not a compliant register — it’s a liability.

Key ongoing obligations include:

• Reviewing the management plan annually — or more frequently if the condition of ACMs changes or if building use changes significantly.
• Updating the asbestos register after any work that disturbs or removes ACMs.
• Reassessing ACM condition periodically, particularly for materials rated as in poor condition or in areas subject to regular disturbance.
• Ensuring new staff and contractors are briefed on the location of ACMs before they begin work.
• Commissioning a new survey before any planned refurbishment, even if a management survey already exists. A management survey is not sufficient for refurbishment work.

Dutyholders who treat asbestos management as a live, evolving process are far better positioned than those who commission a survey, file it away, and consider the job done. The duty to manage is exactly that — an active, continuing duty.

Frequently Asked Questions

What is asbestos compliance and who does it apply to?

Asbestos compliance refers to meeting the legal obligations set out in the Control of Asbestos Regulations and, where relevant, the Construction (Design and Management) Regulations. It applies to anyone who owns, manages, or works in non-domestic premises built before 2000, as well as to clients, designers, and contractors involved in construction and refurbishment projects. Domestic property owners have fewer direct obligations, but they still apply in certain circumstances — particularly where work is carried out by tradespeople.

Do I need an asbestos survey before refurbishment work?

Yes. Before any work that will disturb the fabric of a building, a refurbishment and demolition survey must be carried out in the areas to be disturbed. A management survey alone is not sufficient for this purpose. The survey must be completed before intrusive work begins — not during or after. Failing to commission the correct survey before refurbishment is one of the most common compliance failures identified by the HSE.

What happens if asbestos is found unexpectedly during building work?

Work must stop immediately in the affected area. The suspected material should not be disturbed further. The principal contractor or site supervisor must be informed, and a sample should be taken by a competent person for analysis before work resumes. If the material is confirmed as an ACM and the work constitutes licensable activity, a licensed contractor must be appointed and the HSE notified at least 14 days in advance of the work commencing.

How often should an asbestos management plan be reviewed?

The Control of Asbestos Regulations require that the management plan is reviewed and, where necessary, revised at regular intervals. Annual review is widely regarded as best practice and is what the HSE expects to see. The plan should also be reviewed whenever there is a material change — such as a change in building use, a change in the condition of ACMs, or following any work that has disturbed or removed asbestos-containing materials.

Can any contractor remove asbestos, or does it have to be a licensed company?

The majority of asbestos removal work must be carried out by a contractor holding a current HSE asbestos licence. Licensed work includes removal of sprayed coatings, lagging, asbestos insulating board, and other high-risk materials. Some lower-risk work falls into the category of notifiable non-licensed work (NNLW), which can be carried out without a licence but must still be notified to the relevant enforcing authority and carried out by trained operatives. You can verify a contractor’s licence status through the HSE’s publicly available register.

Asbestos and CDM Regulations: What Every Duty Holder Must Know

Asbestos remains the single largest cause of work-related deaths in the UK, and construction sites are where that risk is most acute. If you need to understand how to effectively handle asbestos under CDM regulations, the answer starts long before anyone picks up a tool — it starts with knowing who is responsible, what the law demands, and what good practice looks like on the ground.

This is not a tick-box exercise. Get it wrong and you face enforcement action, unlimited fines, and — far more seriously — workers developing fatal diseases decades down the line. Get it right and you protect people, protect your business, and keep projects moving safely.

The Legal Framework: Two Sets of Regulations Working Together

Two pieces of legislation govern asbestos on construction projects in the UK. They are distinct but deeply interconnected, and understanding both is essential for anyone managing or working on a construction site.

The Control of Asbestos Regulations

The Control of Asbestos Regulations set the overarching framework for managing asbestos across all workplaces and properties. They establish the duty to manage asbestos in non-domestic premises, define the types of work that require licensed contractors, and set the workplace exposure limit — currently 0.1 fibres per cubic centimetre of air, averaged over a four-hour period.

The regulations make clear that anyone in control of a building has a legal duty to identify asbestos-containing materials (ACMs), assess their condition, and put a management plan in place. This applies to every non-domestic property built before the year 2000 — no exceptions.

The Construction (Design and Management) Regulations

The Construction (Design and Management) Regulations — universally known as CDM — govern how construction projects are planned and managed. They place duties on clients, principal designers, principal contractors, and contractors, with the explicit aim of ensuring health and safety risks are identified and managed throughout every phase of a project.

Under CDM, asbestos is a pre-construction risk that must be addressed before any work begins. The client is responsible for ensuring that relevant pre-construction information — including the results of any asbestos surveys — is gathered and shared with the entire project team. Failing to do this is a breach of CDM duties, full stop.

Together, these two sets of regulations create a clear chain of responsibility. The Control of Asbestos Regulations tell you what must be done. CDM tells you who must do it and when.

Who Is the Duty Holder and What Are Their Responsibilities?

Under the Control of Asbestos Regulations, the duty holder is the person or organisation with responsibility for the maintenance and repair of a non-domestic building. In practice, this is usually the building owner, the landlord, or the employer who occupies the premises.

Under CDM, the client takes on a distinct but related set of duties. The client must ensure that suitable arrangements are in place for managing the project, that pre-construction information is provided to designers and contractors, and that a construction phase plan is prepared before work begins.

Crucially, these responsibilities are not transferable by simply pointing at someone else. Even if you appoint a principal contractor to manage the site, you as the client retain overarching duties. The law does not allow you to outsource accountability.

In practical terms, the duty holder must:

• Identify whether ACMs are present through a suitable survey
• Assess the condition and risk of any ACMs found
• Produce and maintain an asbestos register
• Develop a written asbestos management plan
• Ensure anyone who might disturb ACMs is informed of their location and condition
• Monitor the condition of ACMs periodically and update records accordingly

If you are unsure whether your building has been surveyed or whether existing records are adequate, do not assume they are. Pre-construction asbestos information must be current and reliable.

Asbestos Surveys: The Essential Starting Point Under CDM

You cannot manage what you have not found. Before any construction, refurbishment, or demolition work begins on a pre-2000 building, an asbestos survey is legally required. The type of survey you need depends on the nature of the work planned.

Management Surveys

A management survey is the standard survey for buildings in normal occupation and use. It identifies ACMs that could be disturbed during routine maintenance and minor works, and provides the baseline information needed to manage asbestos safely on a day-to-day basis.

Every non-domestic building constructed before 2000 should have one. It forms the foundation of your asbestos register and management plan, and it is the starting point for any construction project on an occupied premises.

Refurbishment and Demolition Surveys

If you are planning significant refurbishment or any form of demolition, you need a demolition survey. This is a more intrusive process — it involves accessing areas that are normally concealed, including voids, ceiling spaces, and the fabric of the building itself.

This survey must be completed before work begins. It is a CDM requirement and a requirement under the Control of Asbestos Regulations. There is no grey area: starting work without this survey in place is unlawful.

Survey findings must be shared with all relevant parties — principal designers, principal contractors, and any specialist subcontractors who may encounter ACMs during the works.

What Happens During a Survey

A qualified surveyor will inspect the building systematically, taking samples from suspect materials for laboratory analysis. Samples are tested to confirm whether asbestos is present and, if so, which type.

The three main types — chrysotile (white), amosite (brown), and crocidolite (blue) — carry different risk profiles, with crocidolite and amosite generally considered the most hazardous. Survey reports record the location, type, condition, and risk score of every ACM found, forming the basis of your asbestos register and informing every decision about how to manage or remove materials going forward.

Building and Maintaining an Asbestos Register

An asbestos register is a live document — not something you commission once and file away. It must be kept up to date and made accessible to anyone who might disturb ACMs in the building, including contractors, maintenance workers, and emergency services.

The register should record:

• The exact location of every ACM in the building
• The type of asbestos identified
• The condition and risk score of each material
• The date of the last inspection
• Any actions taken or planned

Registers should be reviewed every six to twelve months as a minimum. If building work alters the condition or location of any ACMs, the register must be updated immediately.

A register that does not reflect the current state of the building is not just inadequate — it is actively dangerous. Store both a physical and a digital copy, and make sure site staff know where to find it. On a construction project, this information must be included in the pre-construction information pack provided to contractors at tender stage.

The Construction Phase Plan and Asbestos

Under CDM, the principal contractor is responsible for preparing the construction phase plan before work begins on site. This plan must address all significant risks — and on any pre-2000 building, asbestos is almost always one of them.

The construction phase plan should set out:

• The findings of the asbestos survey and the location of any ACMs
• How ACMs will be managed, encapsulated, or removed before or during works
• Which contractors are licensed to carry out notifiable asbestos work
• Emergency procedures if asbestos is unexpectedly disturbed
• How workers will be informed about asbestos risks on site
• Air monitoring arrangements during asbestos removal works

The plan is not a static document. It should be updated as the project progresses and as new information comes to light. If asbestos is discovered during works that was not identified in the survey — which does happen — work must stop immediately in the affected area, and the plan must be revised before work resumes.

Selecting Competent Contractors for Asbestos Work

Not every contractor can legally carry out asbestos removal work. The Control of Asbestos Regulations distinguish between three categories of work, and the licensing requirements differ for each.

Licensed Work

The most hazardous asbestos work — including work on sprayed coatings, lagging, and asbestos insulating board — must be carried out by a contractor licensed by the HSE. Licensed contractors must notify the HSE at least 14 days before work begins, provide health surveillance for their workers, and keep health records for a minimum of 40 years.

When appointing a licensed contractor, always verify their licence is current and covers the type of work required. Ask to see their method statements and risk assessments before they begin. A reputable contractor will provide these without hesitation.

Notifiable Non-Licensed Work

Some asbestos work does not require a licence but must still be notified to the relevant enforcing authority. This category includes work on certain asbestos cement products and textured coatings. Workers carrying out this type of work must receive appropriate training and supervision, and health surveillance is also required.

Non-Licensed Work

A small category of lower-risk asbestos work can be carried out without a licence, provided workers are trained and the work is carried out in accordance with a written risk assessment. Even here, proper controls — respiratory protective equipment, controlled work methods, and appropriate disposal — are mandatory.

Under CDM, the client and principal contractor share responsibility for ensuring that only competent, appropriately licensed contractors are appointed for asbestos work. Checking credentials is a legal obligation, not a courtesy. When commissioning asbestos removal, always confirm the contractor holds a current HSE licence before any work begins.

How to Effectively Handle Asbestos Under CDM Regulations: Controlling Exposure on Site

When asbestos work is taking place on site, exposure controls must be in place from the moment work begins. The hierarchy of control applies here as it does to any other workplace hazard: eliminate where possible, substitute where you can, and control what remains.

Practical control measures include:

• Establishing a clearly defined asbestos work area with physical barriers and warning signage
• Using wet methods to suppress dust during removal
• Providing appropriate respiratory protective equipment (RPE) — the correct type for the work being done, not just any mask
• Ensuring workers wear disposable coveralls and that these are disposed of as contaminated waste
• Using H-class vacuum cleaners and damp wiping for decontamination — never dry sweeping or compressed air
• Setting up a decontamination unit where workers can clean themselves and their equipment before leaving the work area
• Conducting air monitoring during and after removal works to verify that fibre levels remain below the control limit

Workers must be trained before they handle or work near asbestos. The level of training required depends on the type of work — licensed work requires specific asbestos training, while non-licensed work requires awareness training as a minimum. Training records should be kept and available for inspection.

Disposing of Asbestos Waste Correctly

Asbestos waste is classified as hazardous waste and must be disposed of in accordance with the relevant environmental regulations. Cutting corners here carries serious legal and health consequences.

The correct procedure is:

1. Double-bag all asbestos waste in heavy-duty polythene bags clearly labelled with asbestos hazard warnings
2. Seal bags securely and store them in a locked, designated area away from the working site
3. Use a licensed waste carrier to transport asbestos waste to a licensed disposal facility
4. Obtain and retain a waste transfer note for every consignment — you are legally required to keep these records
5. Never mix asbestos waste with general construction waste or place it in a skip

Unlicensed disposal of asbestos waste is a criminal offence. The Environment Agency and local authorities have powers to investigate and prosecute, and penalties can be severe. If in doubt, ask your licensed asbestos contractor to manage waste disposal as part of their scope of work.

What to Do If Asbestos Is Discovered Unexpectedly

Even with a thorough survey in place, unexpected discoveries happen. Asbestos can be concealed within building materials, hidden behind linings, or present in forms that were not accessible during the original survey. Knowing how to respond is critical.

If suspected ACMs are disturbed or discovered unexpectedly during works:

1. Stop work immediately in the affected area
2. Isolate the area and prevent anyone from entering
3. Do not attempt to clean up or remove the material yourself
4. Notify the principal contractor and site manager immediately
5. Arrange for a qualified surveyor to inspect and sample the material
6. Do not resume work in the area until the material has been assessed and, if necessary, removed by a licensed contractor
7. Update the asbestos register and construction phase plan to reflect the new information

Speed matters here — but so does caution. The instinct to keep a project moving is understandable, but resuming work before the risk is properly assessed puts workers in danger and exposes the client and principal contractor to serious legal liability.

Frequently Asked Questions

What is the difference between CDM regulations and the Control of Asbestos Regulations?

The Control of Asbestos Regulations set the legal requirements for identifying, managing, and removing asbestos across all non-domestic premises. CDM regulations govern how construction projects are planned and managed, placing specific duties on clients, principal designers, and principal contractors. On a construction project, both sets of regulations apply simultaneously — CDM determines who is responsible and when, while the Control of Asbestos Regulations determine what must actually be done.

Do I need an asbestos survey before starting any building work?

Yes, if the building was constructed before the year 2000 and you are planning refurbishment or demolition work, a refurbishment and demolition survey is legally required before work begins. For buildings in normal occupation, a management survey should already be in place. The type of survey required depends on the nature and extent of the planned works — a qualified surveyor can advise you on which is appropriate for your project.

Who is responsible for asbestos management on a CDM project?

Responsibility is shared across several duty holders. The client must provide pre-construction information, including asbestos survey results, to the project team. The principal designer must consider asbestos risks during the design phase. The principal contractor must address asbestos in the construction phase plan and ensure only competent, licensed contractors carry out asbestos work. Even with these appointments in place, the client retains overarching legal responsibility and cannot simply delegate it away.

What happens if asbestos is found unexpectedly during construction works?

Work must stop immediately in the affected area. The site must be isolated and no further work should take place until the material has been inspected, sampled, and assessed by a qualified surveyor. If the material is confirmed to contain asbestos, a licensed contractor must be appointed to manage or remove it before works resume. The asbestos register and construction phase plan must both be updated to reflect the discovery.

How do I check whether an asbestos contractor is properly licensed?

You can verify an asbestos contractor’s licence status directly through the HSE’s online register of licensed asbestos contractors. A valid licence will specify the types of work the contractor is authorised to carry out. Always check the licence before appointing a contractor for notifiable or licensed asbestos work, and ask to see their current method statements and risk assessments. A reputable contractor will provide this documentation as a matter of course.

CDM and Asbestos: What Every Dutyholder Must Understand About the Legal Framework

If you are planning construction, refurbishment, or demolition work on any building constructed before 2000, the CDM asbestos legal framework is not optional reading — it is the foundation of your legal duty. Two sets of regulations sit at the heart of this framework: the Construction (Design and Management) Regulations and the Control of Asbestos Regulations. Together, they create an interlocking web of responsibilities that applies to clients, designers, contractors, and building owners alike.

Getting this wrong carries serious consequences. The Health and Safety Executive treats asbestos breaches with the utmost gravity, and the courts have handed down unlimited fines and custodial sentences to those who fail their duties. Understanding how these regulations interact is not just good practice — it is a legal necessity.

The Key Legislation Underpinning the CDM Asbestos Legal Framework

Three sets of regulations form the backbone of asbestos safety in construction. Each has a distinct role, but they are designed to complement one another. Knowing where one ends and another begins will help you meet your obligations without gaps.

Control of Asbestos Regulations

The Control of Asbestos Regulations is the primary legislation governing how asbestos must be managed, identified, and controlled in buildings across Great Britain. It applies to all non-domestic premises and to the common areas of residential buildings such as blocks of flats.

Under these regulations, dutyholders — typically building owners or those responsible for maintenance — must identify whether asbestos-containing materials (ACMs) are present, assess their condition, and put in place a written management plan. That plan must be kept up to date and shared with anyone who might disturb the materials, including contractors and emergency services.

The regulations also set out strict requirements for licensed asbestos work. Higher-risk activities — such as removing asbestos insulation or asbestos insulating board — can only be carried out by a contractor holding a licence issued by the HSE. Air monitoring must follow any removal work to confirm the area is safe before reoccupation.

Construction (Design and Management) Regulations

CDM applies to virtually all construction projects in Great Britain, from large commercial developments to smaller domestic renovations. The regulations assign specific duties to each party involved in a project: the client, the principal designer, the principal contractor, and individual contractors.

Asbestos sits squarely within CDM’s scope. Pre-construction information — which must be gathered and shared before work begins — must include details of any known or suspected ACMs. The principal designer is responsible for coordinating this information and ensuring it flows to those who need it. The construction phase plan must then address how asbestos risks will be managed on site.

CDM also requires that a health and safety file is compiled during the project and handed to the client on completion. Where asbestos remains in a building after work is finished, that file must record its location, type, and condition so future occupiers and contractors are not left in the dark.

Control of Substances Hazardous to Health Regulations (COSHH)

COSHH sits alongside the asbestos-specific regulations and applies wherever workers may be exposed to hazardous substances — including asbestos fibres. Under COSHH, employers must carry out suitable risk assessments and implement control measures to prevent or adequately control exposure.

In practice, COSHH requires that suspect materials are treated as if they contain asbestos until testing confirms otherwise. Employers cannot simply assume a material is safe because it looks intact. The regulations demand a precautionary approach, and that approach must be documented.

How CDM and Asbestos Regulations Work Together

The CDM asbestos legal framework is not two separate systems running in parallel — it is an integrated set of duties that reinforce one another. Understanding how they interact is crucial for anyone managing a construction project in a building that may contain asbestos.

Pre-Construction Information and Asbestos Surveys

Before a single tool is picked up, the client must ensure that adequate pre-construction information is in place. For any building constructed before 2000, this means commissioning an appropriate asbestos survey. The type of survey required depends on the scope of work.

For ongoing management of a building without intrusive work, a management survey is the standard requirement. It identifies ACMs in accessible areas and assesses their condition so a management plan can be put in place.

Where refurbishment is planned, a refurbishment survey is required. This is a more intrusive inspection that locates all ACMs in areas where work will take place, including inside walls, floors, and ceilings. The survey must be completed before work begins — not during it.

For full demolition projects, a demolition survey is required before any structural work commences. This is the most thorough form of survey and must cover the entire structure, including areas that are difficult to access.

The HSE’s guidance document HSG264 sets out the standards that asbestos surveys must meet. Surveyors must be competent, and the resulting report must provide enough information for those planning the work to understand the risks they face.

Roles and Responsibilities Under the CDM Asbestos Legal Framework

One of CDM’s most important contributions is the clarity it brings to roles. When it comes to asbestos, each dutyholder has specific responsibilities that cannot simply be passed down the chain.

• Clients must ensure that pre-construction information — including asbestos survey findings — is provided to the principal designer and principal contractor before work starts. They must also ensure that suitable arrangements are in place for managing the project safely.
• Principal designers must incorporate asbestos risk information into the design process. Where possible, design decisions should reduce or eliminate the need to disturb ACMs. They must also ensure that asbestos information is communicated clearly to all parties.
• Principal contractors must include asbestos management measures in the construction phase plan. This includes arrangements for licensed removal work, air monitoring, and how unexpected discoveries of asbestos will be handled.
• Contractors must not disturb materials they suspect contain asbestos without proper assessment and, where necessary, licensed removal. They must follow the construction phase plan and report any unexpected finds immediately.

The Construction Phase Plan and Asbestos

The construction phase plan is a live document that must be in place before work begins and updated as the project progresses. For projects where asbestos is present or suspected, the plan must set out:

1. The location and type of ACMs identified in the pre-construction survey
2. How ACMs will be managed or removed before or during the works
3. The arrangements for licensed asbestos removal, including notification to the HSE where required
4. Air monitoring procedures following any removal work
5. What to do if unexpected asbestos is discovered during the project

A plan that simply lists asbestos as a hazard without addressing these specifics is unlikely to satisfy the HSE. Inspectors expect to see practical, site-specific measures — not generic statements.

Dutyholder Obligations: What the Law Requires Day to Day

Beyond the project-specific requirements of CDM, building owners and managers carry ongoing duties under the Control of Asbestos Regulations. These do not switch off between construction projects — they apply continuously to any non-domestic premises where ACMs may be present.

The Duty to Manage

The duty to manage asbestos requires that dutyholders take reasonable steps to find out whether ACMs are present in their premises. Where they are found, the dutyholder must assess the risk they pose and prepare a written plan for managing that risk.

The management plan must be kept under review and updated whenever circumstances change — for example, if a survey reveals additional materials, or if the condition of known ACMs deteriorates. The plan must be accessible to anyone who might need it, including maintenance contractors and emergency responders.

Record-Keeping and Communication

Good record-keeping is not just administrative good practice — it is a legal requirement. Dutyholders must maintain up-to-date records of:

• The location and type of all known or presumed ACMs
• The condition of those materials and any changes over time
• Work carried out on or near ACMs, including removal, encapsulation, or repair
• Air monitoring results following any disturbance of ACMs
• Training records for anyone working with or near asbestos

This information must be shared with contractors before they begin any work that could disturb ACMs. Failure to do so puts workers at risk and exposes the dutyholder to significant legal liability.

Training and Competence

Only trained and, where required, licensed personnel may work with asbestos. Under the Control of Asbestos Regulations, anyone who is liable to disturb ACMs in the course of their work must receive appropriate training. This applies to maintenance workers, electricians, plumbers, and anyone else working in buildings where ACMs may be present.

For licensed work — which covers the highest-risk activities — contractors must hold a current HSE licence, and workers must receive specific training that meets the standards set out in HSE guidance. Clients and principal contractors have a duty to check that any asbestos contractor they engage holds the appropriate licence before work commences.

Where asbestos removal is required, only a licensed contractor should be engaged. Attempting to cut costs by using unlicensed labour for notifiable work is a criminal offence and places everyone on site at risk.

Penalties for Non-Compliance with the CDM Asbestos Legal Framework

The consequences of failing to comply with the CDM asbestos legal framework are severe. The HSE has broad enforcement powers, and the courts have demonstrated a clear willingness to impose substantial penalties on those who breach their duties.

Criminal Liability

Breaches of the Control of Asbestos Regulations and CDM can result in criminal prosecution. On summary conviction, individuals and companies can face unlimited fines. In the most serious cases — where failures put workers or members of the public at significant risk — custodial sentences can be imposed on individuals, including directors and managers.

The courts have made clear that asbestos-related offences are treated with particular gravity. The latency period of asbestos-related diseases means that the harm caused by a breach today may not become apparent for decades, but that does not reduce the seriousness with which the courts view the original failure.

Improvement and Prohibition Notices

Where the HSE identifies breaches during an inspection, it can issue improvement notices requiring specific actions within a set timeframe. In cases where there is an immediate risk of serious harm, a prohibition notice can halt work entirely until the risk is controlled. Either type of notice can cause significant disruption and cost to a project.

RIDDOR Reporting

The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR) require that certain asbestos-related incidents are reported to the HSE. This includes cases where a worker is diagnosed with an asbestos-related disease attributable to their work, and dangerous occurrences where asbestos control measures fail. Failure to report is itself a criminal offence.

Practical Steps for Compliance

Meeting your obligations under the CDM asbestos legal framework does not have to be complicated, but it does require a structured approach. The following steps will help you build a compliant process from the ground up.

1. Commission the right survey at the right time. Before any construction, refurbishment, or demolition work begins, establish what type of asbestos survey is required and appoint a competent, accredited surveyor to carry it out. Do not rely on old surveys — conditions change, and a survey that was accurate five years ago may not reflect the current state of the building.
2. Share information with all parties. Asbestos survey reports, management plans, and risk assessments must be shared with the principal designer, principal contractor, and all relevant contractors before work begins. Information that sits in a filing cabinet serves no one.
3. Appoint competent contractors. Check that any contractor engaged to work with or near ACMs holds the appropriate qualifications and, where required, an HSE licence. Ask for evidence — do not take assurances at face value.
4. Keep the construction phase plan current. Review and update the plan as the project progresses. If unexpected asbestos is discovered, stop work in the affected area, reassess, and update the plan before resuming.
5. Maintain the health and safety file. Ensure that the file accurately records the location and condition of any ACMs remaining in the building after the project is complete. This protects future occupiers and contractors — and it is a legal requirement.
6. Review your management plan regularly. Even outside of construction projects, the duty to manage asbestos is ongoing. Set a schedule for reviewing your management plan and carrying out condition surveys of known ACMs.

Asbestos Surveys Across the UK: Getting the Right Support

The CDM asbestos legal framework applies equally whether you are managing a project in central London, the North West, or the West Midlands. What matters is that you engage competent surveyors who understand the regulatory requirements and can produce reports that are fit for purpose.

If you are based in the capital and need an asbestos survey in London, Supernova operates across all London boroughs with experienced, accredited surveyors ready to mobilise quickly. For projects in the North West, our asbestos survey in Manchester service covers the city and surrounding areas. In the Midlands, our asbestos survey in Birmingham team provides the same high standard of service for commercial, industrial, and residential clients.

Wherever your project is located, the legal obligations are the same — and the consequences of getting it wrong are equally serious. Choosing a surveying partner with the experience and accreditation to support you through the full process is one of the most important decisions you will make at the outset of any project.

Frequently Asked Questions

What is the CDM asbestos legal framework?

The CDM asbestos legal framework refers to the interlocking set of regulations that govern how asbestos must be managed during construction, refurbishment, and demolition projects. The primary regulations involved are the Construction (Design and Management) Regulations, the Control of Asbestos Regulations, and the Control of Substances Hazardous to Health Regulations. Together, they assign specific duties to clients, principal designers, principal contractors, and individual contractors, covering everything from pre-construction surveys to the management of ACMs during and after a project.

Do CDM regulations apply to asbestos in domestic properties?

CDM applies to virtually all construction projects, including domestic renovations, though the specific duties vary depending on the scale of the project and the parties involved. The Control of Asbestos Regulations, however, apply primarily to non-domestic premises and the common areas of residential buildings such as blocks of flats. For domestic properties, the duty to manage does not apply in the same way, but contractors working in domestic settings still have obligations under COSHH and must not disturb suspect materials without proper assessment.

What type of asbestos survey is required before construction work?

The type of survey required depends on the nature of the work. A management survey is appropriate for ongoing building management without intrusive work. A refurbishment survey is required before any refurbishment work that will disturb the building fabric. A demolition survey is required before any demolition work and must cover the entire structure. HSG264, the HSE’s guidance on asbestos surveys, sets out the standards that each type of survey must meet.

Who is responsible for providing asbestos information before a construction project begins?

Under CDM, the client is responsible for ensuring that adequate pre-construction information — including asbestos survey findings — is provided to the principal designer and principal contractor before work starts. The principal designer is then responsible for coordinating that information and ensuring it is communicated to all relevant parties. Building owners also have an ongoing duty under the Control of Asbestos Regulations to maintain records of ACMs and share them with contractors before any work that could disturb those materials.

What happens if asbestos is discovered unexpectedly during construction work?

Work in the affected area must stop immediately. The discovery should be reported to the principal contractor, who must update the construction phase plan before any work resumes. A competent surveyor should assess the material, and if it is confirmed to contain asbestos, a licensed contractor must carry out any necessary removal work before the area is cleared for reoccupation. The health and safety file and management plan must also be updated to reflect the find.

CDM Regulations and Asbestos: What Every Dutyholder Needs to Know

If you’re commissioning construction work on a pre-2000 building, CDM regulations asbestos requirements are not optional — they are a legal duty that runs through every person in the project chain. Get it wrong and you’re facing unlimited fines, potential imprisonment, and workers exposed to one of the UK’s deadliest occupational hazards.

The Construction (Design and Management) Regulations work hand-in-hand with the Control of Asbestos Regulations to create a framework that protects workers during building, refurbishment, and demolition projects. Understanding how these two sets of regulations interact is essential for clients, principal designers, principal contractors, and anyone else carrying duties on a construction project.

What CDM Regulations Actually Require on Asbestos

The CDM Regulations place clear obligations on dutyholders to identify, assess, and manage asbestos risk before and during construction work. This isn’t a box-ticking exercise — it’s a structured legal duty with real consequences for non-compliance.

At the heart of CDM is the principle that health and safety risks, including asbestos, must be considered at the earliest possible stage of a project. That means before a single wall is touched, before contractors are appointed, and before designs are finalised.

Under CDM, the client has a duty to ensure that pre-construction information — including asbestos survey data — is gathered and shared with all relevant dutyholders. If asbestos-containing materials (ACMs) are present in the building, that information must flow through the entire project team without exception.

Pre-Construction Information and Asbestos

One of the most critical requirements under CDM is the provision of pre-construction information. For any building that might contain asbestos, this means commissioning an appropriate asbestos survey before work begins and including the findings in the pre-construction information pack.

The type of survey required depends entirely on the nature of the work planned. A management survey is suitable for routine maintenance and ongoing building management, but it is not sufficient for intrusive work. Any project involving significant refurbishment or demolition requires a more thorough investigation.

Failing to provide adequate pre-construction information — including asbestos data — is itself a breach of CDM. The HSE takes this seriously, particularly where workers are subsequently exposed to ACMs that a proper survey would have identified.

The Construction Phase Plan

The construction phase plan must address asbestos risk directly. Where ACMs are present or suspected, the plan needs to set out how those materials will be managed, whether they will be removed before work proceeds, and what controls are in place to protect workers.

This isn’t a document that can be produced on the first day of work. CDM requires the construction phase plan to be prepared before the construction phase begins — which means asbestos information needs to be available before that point. Leaving it until the last minute is a compliance failure, not an administrative oversight.

How CDM and the Control of Asbestos Regulations Work Together

CDM regulations asbestos duties don’t exist in isolation. They sit alongside the Control of Asbestos Regulations, which set out specific requirements for managing and working with ACMs. Understanding how these two frameworks interact is essential for anyone managing a construction project.

The Control of Asbestos Regulations establish the duty to manage asbestos in non-domestic premises, the requirements for asbestos surveys, and the rules around licensed and non-licensed asbestos work. CDM builds on this by embedding asbestos risk management into the broader construction project framework.

In practice, an asbestos survey carried out to satisfy the Control of Asbestos Regulations also serves as a key input into the CDM pre-construction information. The two sets of regulations are complementary — compliance with one actively supports compliance with the other.

The Duty to Manage Asbestos

For non-domestic premises, the duty to manage asbestos requires the dutyholder — typically the building owner or the person in control of the premises — to identify ACMs, assess their condition, and put in place a written management plan.

This duty exists independently of any construction work. However, when construction work is planned, the duty to manage asbestos becomes directly relevant to CDM compliance. The asbestos register and management plan form part of the pre-construction information that the client must provide under CDM.

If no asbestos register exists, the client must commission a survey before work begins. Providing incomplete or out-of-date asbestos information to the project team is a failure of both the duty to manage asbestos and the CDM pre-construction information duty — there is no grey area here.

Types of Asbestos Survey Required Under CDM Regulations

Selecting the right type of asbestos survey is a fundamental part of CDM compliance. The HSE’s guidance document HSG264 sets out the types of asbestos survey and when each is appropriate. Getting this wrong — for example, relying on a management survey when a refurbishment survey is required — can leave workers exposed and the client in breach of their legal duties.

Management Surveys

A management survey is designed to locate ACMs that could be disturbed during normal building occupancy, routine maintenance, and minor works. It involves a visual inspection and sampling of accessible materials, but it is not designed to identify all ACMs in areas that will be disturbed during major refurbishment or demolition.

Under CDM, a management survey is appropriate for providing background asbestos information on a building, but it should not be relied upon as the sole survey for projects involving significant intrusive work. Think of it as a starting point, not a green light to proceed with major works.

Refurbishment Surveys

A refurbishment survey is required before any work that will disturb the fabric of a building — stripping out, fitting out, or any other intrusive work. This type of survey is more thorough than a management survey and involves destructive inspection techniques to access areas that may contain concealed ACMs.

Under CDM regulations, asbestos information from a refurbishment survey must be included in the pre-construction information before the principal contractor prepares the construction phase plan. Without this information, the construction phase plan cannot adequately address asbestos risk.

The refurbishment survey must cover all areas where work will take place. If the scope of work changes during the project and new areas are affected, an additional survey may be required before work in those areas begins — scope creep is a common source of asbestos incidents on construction sites.

Demolition Surveys

For projects involving full or partial demolition, a demolition survey is required. This is the most thorough type of asbestos survey and must cover the entire structure, including all areas that will be demolished. It typically involves significant destructive investigation to ensure that all ACMs are identified before demolition begins.

Under CDM, the demolition survey must be completed before the construction phase plan is finalised and before any demolition work commences. Any ACMs identified must be removed by a licensed contractor before demolition proceeds — this is a legal requirement, not a recommendation.

Dutyholder Responsibilities Under CDM Regulations for Asbestos

CDM regulations asbestos duties are distributed across multiple dutyholders, each with specific responsibilities. Understanding who is responsible for what is essential for effective compliance — and for avoiding the scenario where everyone assumes someone else has dealt with it.

The Client

The client sits at the top of the CDM duty chain and carries significant responsibilities for asbestos management. The client must ensure that suitable asbestos surveys are carried out before work begins, that the survey findings are included in the pre-construction information, and that the project team has the skills and resources to manage asbestos risk effectively.

Domestic clients — individuals having work done on their own home — can pass their CDM duties to the principal contractor or contractor. However, this does not eliminate the need for asbestos surveys on pre-2000 properties. The duty to carry out appropriate surveys remains regardless of who formally holds the CDM client role.

The Principal Designer

The principal designer has a duty to plan, manage, monitor, and coordinate health and safety during the pre-construction phase. For asbestos, this means ensuring that asbestos survey information is gathered, assessed, and incorporated into the pre-construction information pack.

The principal designer should also consider asbestos risk during the design process itself. Where possible, designs should avoid disturbing ACMs or should specify their removal before intrusive work begins. This is the CDM principle of designing out risk at source — it is far more effective than managing risk once workers are already on site.

The Principal Contractor

The principal contractor takes over coordination responsibilities during the construction phase. Their duties include preparing the construction phase plan — which must address asbestos risk — and ensuring that all contractors on site are aware of ACMs and the controls in place.

Where asbestos removal is required before or during construction work, the principal contractor must ensure this is carried out by a licensed contractor where legally required, and that the work is properly planned and supervised. Delegating this to a subcontractor does not remove the principal contractor’s oversight duty.

Contractors and Subcontractors

All contractors working on a project must be provided with relevant asbestos information before they begin work. They must not start work in areas where ACMs may be present without receiving this information and understanding the controls in place.

If a contractor discovers unexpected ACMs during the course of their work, they must stop work immediately, report the discovery, and not resume until the materials have been assessed and appropriate controls are in place. This is a legal requirement under both CDM and the Control of Asbestos Regulations — it is not discretionary.

Enforcement and Consequences of Non-Compliance

The HSE enforces both CDM regulations and the Control of Asbestos Regulations, and takes a robust approach to asbestos-related breaches. The consequences of non-compliance are serious and can affect every dutyholder in the project chain.

Enforcement action can include improvement notices, prohibition notices, and prosecution. Fines for asbestos-related offences are unlimited in the Crown Court, and custodial sentences are possible in the most serious cases. The HSE has successfully prosecuted clients, contractors, and individuals for failures in asbestos management during construction work.

Beyond the legal consequences, the human cost of asbestos exposure is severe. Asbestos-related diseases — including mesothelioma, lung cancer, and asbestosis — have long latency periods, meaning workers exposed today may not develop symptoms for decades. This makes prevention through proper CDM compliance all the more critical.

RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations) also applies where workers are exposed to asbestos during construction work. Reportable incidents must be notified to the HSE, and failure to report can itself result in enforcement action.

Practical Steps for CDM Asbestos Compliance

Meeting your CDM regulations asbestos duties doesn’t have to be complicated, but it does require a structured approach from the earliest stages of any project. The following steps cover the essentials:

1. Commission the right survey at the right time. Before any pre-construction information is compiled, determine what type of asbestos survey is appropriate for the planned work. Don’t rely on an existing management survey for refurbishment or demolition projects.
2. Include asbestos information in pre-construction information. Ensure that survey reports, asbestos registers, and management plans are included in the pre-construction information pack provided to all dutyholders before work begins.
3. Address asbestos in the construction phase plan. The construction phase plan must specifically address how ACMs will be managed during the project. Generic health and safety statements are not sufficient.
4. Appoint competent contractors. Ensure that any contractor carrying out asbestos-related work holds the appropriate licence where required, and that they have the skills, knowledge, and experience to manage asbestos risk safely.
5. Keep asbestos information up to date. If the scope of work changes, or if unexpected ACMs are discovered, update the asbestos information and revise the construction phase plan accordingly.
6. Communicate asbestos information to all workers. Every person working on the project must be aware of where ACMs are located, what controls are in place, and what to do if they discover unexpected asbestos materials.
7. Ensure removal is completed before intrusive work begins. Where ACMs must be removed before demolition or refurbishment work can proceed, this must happen before — not during — the main works.

Frequently Asked Questions

What is the relationship between CDM regulations and asbestos?

The Construction (Design and Management) Regulations require dutyholders to manage health and safety risks — including asbestos — throughout a construction project. CDM works alongside the Control of Asbestos Regulations to ensure that asbestos-containing materials are identified, assessed, and managed before and during construction, refurbishment, or demolition work. Compliance with both sets of regulations is a legal requirement, not a choice.

Do CDM regulations apply to domestic properties?

CDM regulations do apply to domestic projects, though domestic clients can transfer certain duties to the principal contractor or contractor. However, this does not remove the requirement to carry out appropriate asbestos surveys on pre-2000 properties before intrusive work begins. The duty to identify and manage asbestos remains regardless of how CDM client duties are allocated.

What type of asbestos survey is required under CDM?

The type of survey required depends on the nature of the work. A management survey is appropriate for routine maintenance and minor works. A refurbishment survey is required before any work that will disturb the fabric of a building. A demolition survey is required before any full or partial demolition. HSG264 provides detailed guidance on selecting the appropriate survey type for any given project.

Who is responsible for asbestos management under CDM?

Responsibility is shared across the project team. The client is responsible for commissioning appropriate surveys and providing pre-construction information. The principal designer coordinates asbestos risk management during the pre-construction phase. The principal contractor addresses asbestos in the construction phase plan and ensures all site workers are informed. Every dutyholder in the chain carries specific legal responsibilities.

What happens if asbestos is discovered unexpectedly during construction work?

If unexpected asbestos-containing materials are discovered during construction work, work must stop immediately in the affected area. The discovery must be reported to the principal contractor, and work must not resume until the materials have been assessed by a competent person and appropriate controls are in place. This is a legal requirement under both CDM and the Control of Asbestos Regulations. An additional asbestos survey may be required to assess the extent of the materials before work can safely continue.

CDM Regulations and Asbestos Management: What Every Duty Holder Must Know

Asbestos kills more people in the UK every year than any other single work-related cause. If you own, manage, or are developing a property built before 2000, understanding how CDM regulations form a crucial aspect of asbestos management is not optional reading — it is the legal framework that determines how safely your project proceeds, and who is liable when something goes wrong.

The Construction (Design and Management) Regulations sit alongside the Control of Asbestos Regulations to create a joined-up duty of care for everyone involved in construction work. Understanding how these two frameworks interact is essential for clients, principal designers, contractors, and property owners alike.

What Are the CDM Regulations and Why Do They Matter for Asbestos?

The CDM Regulations govern health and safety in the construction industry across Great Britain. Their core purpose is to ensure that safety — including the management of hazardous materials like asbestos — is considered at every stage of a project, from initial design through to completion and handover.

Asbestos is explicitly central to CDM compliance because it remains present in millions of buildings constructed before 2000. Any construction, refurbishment, or demolition activity on such a building carries a real risk of disturbing asbestos-containing materials (ACMs), which releases fibres that cause fatal diseases including mesothelioma and asbestosis.

The CDM Regulations require duty holders to plan, manage, and monitor construction work so that risks are identified and controlled before anyone is exposed. For pre-2000 buildings, asbestos must sit at the top of every pre-construction risk assessment — without exception.

How CDM and the Control of Asbestos Regulations Work Together

The CDM Regulations and the Control of Asbestos Regulations are separate pieces of legislation, but they are designed to complement each other. Neither replaces the other — both apply simultaneously to most construction projects involving older buildings.

The Control of Asbestos Regulations place a duty to manage asbestos on the owners and occupiers of non-domestic premises. They require that an asbestos survey is carried out, that ACMs are recorded in a register, and that a management plan is put in place and reviewed regularly.

The CDM Regulations then require that this information — the survey findings, the register, the management plan — is shared with everyone involved in the project. Principal designers must incorporate asbestos risk into the pre-construction phase. Contractors must receive that information before any work begins on site.

In practice, this means an management survey is not just good practice — it is a legal prerequisite for any construction work on a qualifying building.

Key Duty Holders Under CDM and Their Asbestos Responsibilities

One of the most significant features of the CDM Regulations is the clear allocation of duties to named roles. Each duty holder has specific responsibilities when it comes to asbestos. Confusion about who is responsible is not a defence — the law is explicit.

The Client

The client — the person or organisation commissioning the construction work — carries the broadest obligations. Clients must ensure that an asbestos survey has been carried out and that the findings are made available to all other duty holders before work begins.

Clients must also appoint competent principal designers and principal contractors where a project involves more than one contractor. Cutting corners on survey costs is not a risk worth taking — the client is responsible for ensuring that adequate time and resources are allocated for asbestos management throughout the project lifecycle.

The Principal Designer

The principal designer is responsible for planning, managing, monitoring, and coordinating health and safety during the pre-construction phase. In the context of asbestos, this means reviewing survey information, incorporating asbestos risks into the construction phase plan, and ensuring that all design decisions account for the presence of ACMs.

Where a design decision could disturb asbestos — for example, routing new services through a ceiling containing asbestos insulating board — the principal designer must address that risk at the design stage, not leave it to be discovered on site.

The Principal Contractor

The principal contractor takes over coordination responsibility during the construction phase. They must ensure that the construction phase plan addresses asbestos risks, that all workers are briefed on the location of ACMs, and that no work disturbs asbestos without the appropriate controls in place.

If asbestos is unexpectedly discovered during work, the principal contractor must have a stop-work procedure in place. Work must not resume until the situation has been properly assessed and controlled by a competent person.

Contractors and Workers

Individual contractors — including subcontractors — must cooperate with the principal contractor, follow the construction phase plan, and ensure their workers have received appropriate asbestos awareness training.

Workers themselves have a duty to follow safe systems of work and to report any suspected ACMs they encounter. This is not a passive obligation — active communication on site can prevent a serious exposure incident.

Asbestos Surveys: The Foundation of CDM Compliance

No CDM-compliant asbestos management plan can exist without a proper survey. The HSE’s guidance document HSG264 sets out the two main types of asbestos survey and when each is required. Getting the right survey type for your project is not a technicality — it is a legal obligation.

Management Surveys

A management survey is required for the ongoing management of ACMs in occupied or operational buildings. It locates, as far as reasonably practicable, the presence and condition of ACMs that could be disturbed during normal occupation and maintenance.

The results feed directly into the asbestos register and management plan that CDM duty holders need to share across the project team. For property managers and building owners, commissioning a management survey is the starting point for both Control of Asbestos Regulations compliance and CDM readiness.

Refurbishment and Demolition Surveys

Where a building or part of it is to be refurbished or demolished, a refurbishment and demolition survey is required. This is a more intrusive survey — it may involve destructive inspection to locate ACMs that a management survey would not uncover.

A demolition survey must be completed before any refurbishment or demolition work begins. Attempting to proceed with construction work using only a management survey, or with no survey at all, is a serious breach of both the CDM Regulations and the Control of Asbestos Regulations.

Risk Assessment and Control Measures on Site

Identifying asbestos through a survey is only the first step. The CDM Regulations require that identified risks are assessed and controlled throughout the construction phase. This is an active, ongoing obligation — not a box-ticking exercise completed at the start of a project.

Pre-Construction Risk Assessment

Before any work begins, the principal designer should ensure that asbestos risks are documented in the pre-construction information pack. This includes the location and condition of all known ACMs, the type of asbestos involved, and any specific risks associated with the planned work.

Contractors should review this information thoroughly before preparing their own method statements and risk assessments for any work that could disturb ACMs. Receiving the information is not enough — it must be acted upon.

Controls During Construction Work

Where work must be carried out in areas containing ACMs, strict controls apply:

• The work area must be segregated and clearly signed to prevent unauthorised access
• Air monitoring must be carried out to ensure fibre concentrations remain within legal limits
• Workers must wear appropriate personal protective equipment, including RPE (respiratory protective equipment) of the correct specification
• Waste containing asbestos must be double-bagged in clearly labelled, UN-approved sacks and disposed of at a licensed waste facility
• The work area must be thoroughly cleaned using H-class vacuum equipment after work is complete

Licensed and Non-Licensed Work

Not all asbestos work requires a licensed contractor, but the highest-risk materials — including asbestos insulation, asbestos insulating board, and asbestos coatings — must only be removed by a contractor licensed by the HSE. Attempting to remove these materials without a licence is a criminal offence.

For materials that fall into the non-licensed category, a risk assessment is still required, and the work must still be carried out safely. Some non-licensed work must be notified to the HSE before it begins. When in doubt, always seek professional advice before proceeding.

Supernova’s asbestos removal service covers the full spectrum of removal work, from licensed removal of high-risk materials to the safe handling of lower-risk ACMs.

Training Requirements Under CDM and the Control of Asbestos Regulations

Both the CDM Regulations and the Control of Asbestos Regulations require that workers are adequately trained. Asbestos awareness training is a legal requirement for any worker who could come into contact with, or disturb, ACMs in the course of their work.

The level of training required depends on the nature of the work:

• Asbestos awareness training is required for all workers in trades that could encounter asbestos — electricians, plumbers, joiners, plasterers, and many others. This training must be refreshed regularly.
• Non-licensed work training is required for workers carrying out non-licensed asbestos work. This goes beyond awareness to include practical skills in safe working methods.
• Licensed work training is required for all operatives working for HSE-licensed asbestos removal contractors. This is the most comprehensive level of training and includes medical surveillance requirements.

Employers must ensure that training records are maintained and that training is kept up to date. Sending an untrained worker into an area containing ACMs is a serious breach of the law — and a serious risk to that worker’s health.

Record-Keeping, Notification, and the Health and Safety File

The CDM Regulations place significant emphasis on documentation. Good record-keeping is not just an administrative exercise — it protects workers, protects property owners, and provides an audit trail in the event of a regulatory investigation or legal claim.

Notification to the HSE

Projects that meet certain thresholds — more than 30 working days with more than 20 workers simultaneously, or exceeding 500 person-days — must be notified to the HSE using the F10 form. This notification must be made before the construction phase begins.

Separately, under the Control of Asbestos Regulations, licensed asbestos removal work must be notified to the HSE at least 14 days before work commences. This notification must include details of the work, the location, the estimated duration, and the contractor carrying it out.

The Health and Safety File

At the end of a project, the principal designer is responsible for compiling and handing over the health and safety file to the client. This file must contain all information relevant to the future health and safety of the structure — including the location and condition of any ACMs that remain in place.

This file is a living document. If asbestos is removed during the project, the file must reflect that. If ACMs are left in place and managed, their location must be clearly recorded. Future owners, occupiers, and contractors will rely on this information — gaps in the file can have serious consequences years or even decades down the line.

Asbestos Work Records

Employers who carry out licensed asbestos work must keep records of that work for a minimum of 40 years. This reflects the long latency period of asbestos-related diseases — symptoms may not appear until decades after exposure.

Workers who have been exposed to asbestos during licensed work are entitled to access their own exposure records. Maintaining accurate records is both a legal duty and a matter of basic fairness to the people who carry out this work.

CDM Compliance Across the UK: Regional Considerations

The CDM Regulations apply uniformly across Great Britain, but the practical landscape of asbestos risk varies by region. Areas with heavy industrial heritage — including former manufacturing centres and port cities — tend to have a higher concentration of pre-2000 buildings with significant ACM content.

Supernova Asbestos Surveys operates nationwide. Whether you need an asbestos survey London for a commercial refurbishment in the capital, an asbestos survey Manchester for an industrial unit in the north-west, or an asbestos survey Birmingham for a mixed-use development in the Midlands, our surveyors are experienced in the specific building stock and regulatory environment of each area.

Local knowledge matters. Understanding the construction methods and materials common to a particular era and region helps our surveyors identify ACMs that a less experienced team might overlook.

Common Mistakes That Put Projects at Risk

Even experienced construction professionals make avoidable errors when it comes to CDM and asbestos. These are the mistakes that most commonly lead to enforcement action, project delays, and — most seriously — worker harm.

• Commissioning the wrong survey type. Using a management survey for a refurbishment project is a breach of both the CDM Regulations and the Control of Asbestos Regulations. Always match the survey type to the scope of work.
• Failing to share survey information. Survey findings must be distributed to all relevant duty holders before work begins. Keeping the asbestos register in a filing cabinet where no one can access it defeats the purpose entirely.
• Assuming a building is asbestos-free. Unless a full refurbishment and demolition survey has been completed and confirmed the absence of ACMs, no assumption of asbestos-free status is safe or legally defensible.
• Inadequate stop-work procedures. Every construction phase plan for a pre-2000 building should include a clear, written procedure for what happens if suspected ACMs are discovered unexpectedly. This must be communicated to all workers before work begins.
• Overlooking training obligations. Asbestos awareness training is not a one-off event. It must be refreshed regularly, and records must be maintained. Relying on a worker’s verbal assurance that they have been trained is not sufficient.

Frequently Asked Questions

Do the CDM Regulations apply to small refurbishment projects?

The CDM Regulations apply to all construction projects, regardless of size. Even a small single-contractor refurbishment carries CDM duties. The specific requirements — such as the appointment of a principal designer and principal contractor — apply when more than one contractor is involved. However, the duty to manage asbestos and share relevant information applies to every project on a pre-2000 building, without exception.

What happens if asbestos is found unexpectedly during construction work?

Work must stop immediately in the affected area. The principal contractor must implement the stop-work procedure set out in the construction phase plan. A competent person — typically a qualified asbestos surveyor or consultant — must assess the situation before work can resume. Under no circumstances should workers attempt to remove or disturb suspected ACMs without the appropriate training, equipment, and, where required, an HSE licence.

Who is responsible for the asbestos survey — the client or the contractor?

Under the Control of Asbestos Regulations, the duty to manage asbestos rests with the owner or occupier of non-domestic premises. Under the CDM Regulations, the client is responsible for ensuring that pre-construction information — including asbestos survey findings — is available before work begins. In practice, this means the client must commission the appropriate survey and ensure the results are shared with all duty holders. Contractors cannot be expected to manage risks they have not been informed about.

Is a management survey sufficient for a refurbishment project?

No. HSG264 is clear that a refurbishment and demolition survey is required before any refurbishment or demolition work that could disturb the fabric of a building. A management survey is designed for ongoing management of ACMs in occupied buildings — it is not intrusive enough to locate all ACMs that could be disturbed during refurbishment work. Using only a management survey for a refurbishment project is a breach of the Control of Asbestos Regulations and leaves the project team exposed to serious legal and health risks.

How long must asbestos work records be kept?

Records relating to licensed asbestos work must be kept for a minimum of 40 years. This extended retention period reflects the long latency of asbestos-related diseases, which may not manifest until decades after exposure. Employers must make these records available to workers who request access to their own exposure history.

Work With a Surveying Team That Understands CDM

Getting CDM and asbestos management right requires more than ticking boxes — it requires surveyors who understand how the regulatory frameworks interact and what duty holders actually need to stay compliant and keep their workers safe.

Supernova Asbestos Surveys has completed over 50,000 surveys nationwide. Our UKAS-accredited surveyors provide management surveys, refurbishment and demolition surveys, and asbestos removal services that are fully aligned with CDM requirements and HSG264 guidance.

CDM Regulations and Asbestos: What Every Dutyholder Needs to Know

If you’re managing or commissioning construction work on a pre-2000 building, CDM regulations asbestos duties are not optional — they are a legal requirement that carries serious consequences when ignored. The Construction (Design and Management) Regulations sit alongside the Control of Asbestos Regulations to create a framework that protects workers, site visitors, and the public from one of the UK’s most persistent occupational health hazards.

Asbestos-related disease still kills thousands of people in the UK every year. Many of those deaths trace back to construction work where asbestos was disturbed without proper planning, surveys, or controls. CDM 2015 exists precisely to prevent that from happening again.

This post cuts through the complexity and gives you a clear picture of what CDM requires, who is responsible, and what happens when things go wrong.

What CDM 2015 Actually Says About Asbestos

The Construction (Design and Management) Regulations 2015 replaced earlier versions of the legislation and introduced clearer duty-holder roles across all construction projects in Great Britain. While CDM 2015 covers a broad range of health and safety responsibilities, asbestos is one of the most significant hazards it addresses — particularly for work on older buildings.

CDM 2015 doesn’t operate in isolation. It works in tandem with the Control of Asbestos Regulations, which set out specific duties around managing, surveying, and removing asbestos-containing materials (ACMs). Together, these two sets of regulations create a layered duty of care that applies to everyone involved in a construction project — from the client who commissions the work to the contractor who swings the first hammer.

The scope is broad. CDM 2015 applies to all construction work in Great Britain, including maintenance, refurbishment, fit-out, and demolition. If your building was constructed or refurbished before 2000, asbestos must be treated as a live risk until a professional survey proves otherwise.

The Duty to Manage: Where It All Starts

Before any construction work begins on a non-domestic building — or the common areas of a residential block — the duty to manage asbestos under the Control of Asbestos Regulations must be satisfied. This means having an up-to-date asbestos register, knowing where ACMs are located, and assessing the risk they present.

For routine building management, a management survey is the appropriate starting point. This type of survey locates and assesses ACMs that could be disturbed during normal occupation and low-level maintenance work. It forms the foundation of your asbestos management plan and feeds directly into CDM planning.

Where refurbishment or demolition is planned, a management survey alone is not sufficient. You need a more intrusive investigation — more on that shortly.

What the Asbestos Register Must Contain

Your asbestos register should record:

• The location of all known or presumed ACMs
• The type of asbestos material (if identified through sampling)
• The condition and risk rating of each material
• Any remedial actions taken or planned
• The date of the survey and the surveyor’s details

This register must be made available to anyone carrying out work on the premises. Under CDM 2015, the client has a specific duty to share pre-construction information — and asbestos data is a core part of that.

Pre-Construction Information and CDM Regulations Asbestos Duties

One of the most important CDM obligations for clients is the provision of pre-construction information. Before a project starts, the client must gather and share all relevant health and safety information with the principal designer and principal contractor. Asbestos survey results and the asbestos register sit at the heart of this requirement.

Failing to provide this information — or providing incomplete information — puts workers at risk and exposes the client to significant legal liability. It’s not enough to have had a survey done years ago. If the building has changed, if the survey is out of date, or if new areas are being opened up, fresh surveys may be required.

For major refurbishment or demolition projects, a demolition survey is legally required before work begins. This is a fully intrusive survey that aims to locate all ACMs throughout the structure, including those in areas that would be inaccessible during normal occupation. The findings must be incorporated into the construction phase plan.

Why Pre-Construction Surveys Cannot Be Skipped

Some clients try to proceed with refurbishment work using only a management survey, assuming it covers everything. It does not. A management survey is designed to be minimally intrusive — it won’t access voids, lift floors extensively, or break into structural elements. A refurbishment or demolition survey will.

If asbestos is discovered unexpectedly during construction work, all work in the affected area must stop immediately. The site must be secured, and a licensed asbestos contractor must be called in before work can resume. This causes significant delays and costs that a proper pre-construction survey would have avoided.

Duty-Holder Roles Under CDM 2015

CDM 2015 assigns specific responsibilities to each party involved in a construction project. Understanding these roles is essential for compliance — and for knowing who is accountable if something goes wrong.

The Client

The client is the organisation or individual for whom the construction work is carried out. Under CDM 2015, clients carry significant responsibilities:

• Ensuring suitable arrangements are in place for managing the project safely
• Appointing a principal designer and principal contractor on notifiable projects
• Providing complete pre-construction information, including asbestos data
• Ensuring the construction phase plan is in place before work starts
• Allocating sufficient time and resources for safe asbestos management
• Maintaining and updating the health and safety file throughout the project

Domestic clients have reduced duties, but these are typically transferred to the principal contractor or designer by default.

The Principal Designer

On projects with more than one contractor, a principal designer must be appointed. Their role in relation to CDM regulations asbestos management is particularly important during the design and planning phase.

The principal designer must review all asbestos survey findings and ensure that the design takes account of asbestos risks. Where possible, they should design out the need to disturb ACMs. They must also coordinate the sharing of asbestos information with all relevant parties and ensure it feeds into the construction phase plan.

The Principal Contractor

The principal contractor takes over the safety coordination role once construction begins. They are responsible for:

• Developing and maintaining the construction phase plan, including asbestos controls
• Ensuring all contractors and workers are aware of asbestos risks and locations
• Verifying that any contractor undertaking licensed asbestos work holds the appropriate HSE licence
• Stopping work immediately if unexpected ACMs are discovered
• Ensuring air monitoring is carried out where required following asbestos removal or encapsulation
• Keeping records of all asbestos-related work carried out on site

Contractors and Workers

Every contractor working on a site has duties under CDM 2015. They must cooperate with the principal contractor, follow the construction phase plan, and ensure their workers are properly trained. Workers must receive adequate asbestos awareness training — this is not optional, and it must be refreshed regularly.

Workers also have a responsibility to report any suspected ACMs they encounter during work. Ignoring or working around suspected asbestos is never acceptable and can result in serious criminal liability.

Asbestos Training Requirements Under CDM

CDM 2015 and the Control of Asbestos Regulations both require that anyone who may encounter asbestos during their work receives appropriate training. The level of training required depends on the nature of the work.

Asbestos awareness training is the baseline requirement for workers in trades that may disturb ACMs incidentally — electricians, plumbers, joiners, and similar occupations. This training covers:

• What asbestos is and why it is dangerous
• Where ACMs are commonly found in buildings
• How to recognise materials that may contain asbestos
• What to do if asbestos is suspected or discovered
• Emergency procedures and who to contact

Workers carrying out non-licensed asbestos work require more detailed training, while those undertaking licensed work must meet the stringent requirements set out in HSE guidance, including HSG264 on asbestos surveying.

Training records must be kept on file and made available for inspection. Site managers should verify training certificates before allowing anyone to work in areas where asbestos is present or suspected.

Licensed vs Non-Licensed Asbestos Work Under CDM

Not all asbestos work requires a licensed contractor, but understanding the distinction is critical for CDM compliance. The Control of Asbestos Regulations set out three categories of work:

1. Licensed work — required for high-risk activities such as removing asbestos insulation, asbestos insulating board, or sprayed coatings. Only contractors holding an HSE licence can carry out this work.
2. Non-licensed notifiable work — lower-risk activities that don’t require a licence but must still be notified to the HSE and require medical surveillance for workers.
3. Non-licensed work — the lowest risk category, such as minor work with asbestos cement in good condition. No licence or notification is required, but safe working practices must still be followed.

Under CDM 2015, the principal contractor must ensure that the correct category of work is identified and that appropriately qualified contractors are appointed. Engaging an unlicensed contractor for licensed work is a serious criminal offence.

Where licensed asbestos removal is required, the work must be planned meticulously, with controlled work areas, appropriate PPE, air monitoring, and proper waste disposal. The construction phase plan must reflect all of this.

Enforcement, Penalties, and What the HSE Looks For

The Health and Safety Executive enforces CDM 2015 and the Control of Asbestos Regulations. Inspectors visit construction sites — including unannounced — and have the power to issue improvement notices, prohibition notices, and prosecute individuals and organisations.

The penalties for non-compliance are severe:

• Unlimited fines for organisations convicted of CDM or asbestos offences
• Up to two years’ imprisonment for individuals in serious cases
• Prohibition notices that shut down work immediately
• Improvement notices requiring specific actions within a set timeframe
• Civil liability for harm caused to workers or third parties

The HSE focuses particularly on whether clients have fulfilled their duty to provide pre-construction information, whether surveys were carried out to the appropriate standard, and whether the construction phase plan adequately addresses asbestos risks. Gaps in any of these areas will attract enforcement action.

It’s worth noting that the HSE can pursue both the organisation and named individuals — directors, project managers, and site managers can all face personal prosecution if they are found to have failed in their CDM duties.

Practical Steps for CDM Asbestos Compliance

Compliance doesn’t have to be complicated if you approach it systematically. Here’s a practical checklist for any construction project on a pre-2000 building:

1. Commission the right survey — management survey for low-level maintenance; refurbishment or demolition survey for any intrusive work
2. Update the asbestos register — ensure it reflects current conditions and is accessible to all relevant parties
3. Include asbestos data in pre-construction information — share survey results and the register with the principal designer and principal contractor before work begins
4. Incorporate asbestos controls into the construction phase plan — document exactly how ACMs will be managed, avoided, or removed
5. Verify contractor competence — check licences, training records, and insurance before appointing anyone for asbestos work
6. Establish a clear reporting procedure — all workers must know what to do if they suspect they’ve found asbestos
7. Arrange air monitoring where required — following removal or encapsulation, clearance certificates must be obtained before re-occupation
8. Update the health and safety file — record all asbestos work carried out during the project for future reference

Regional Considerations: CDM Compliance Across the UK

CDM regulations apply uniformly across Great Britain, but the age and nature of the building stock varies significantly by region. Cities with large concentrations of Victorian and Edwardian commercial property, post-war industrial buildings, and 1960s–1980s office blocks carry a particularly high asbestos risk.

Supernova Asbestos Surveys operates nationwide. If you need an asbestos survey London for a commercial refurbishment, an asbestos survey Manchester ahead of a demolition project, or an asbestos survey Birmingham to satisfy CDM pre-construction information requirements, our surveyors are ready to mobilise quickly.

Frequently Asked Questions

What is the relationship between CDM 2015 and the Control of Asbestos Regulations?

CDM 2015 sets out the overarching framework for health and safety management on construction projects, including the duty to identify and manage hazards before and during work. The Control of Asbestos Regulations provide the specific legal requirements for managing asbestos — including survey obligations, training, and licensing for removal work. Both sets of regulations apply simultaneously on construction projects involving pre-2000 buildings, and compliance with one does not remove the obligation to comply with the other.

Who is responsible for commissioning an asbestos survey under CDM?

The client holds primary responsibility for commissioning asbestos surveys and providing the results as part of pre-construction information. However, the principal designer should advise the client on what surveys are needed, and the principal contractor must ensure the information provided is adequate before work begins. If surveys are missing or out of date, the principal contractor should not proceed until this is rectified.

Does CDM apply to domestic refurbishment projects?

CDM 2015 does apply to domestic projects, but domestic clients have reduced duties. In practice, the duties are usually transferred to the principal contractor or the lead designer. However, this does not remove the asbestos risk — any contractor working on a pre-2000 domestic property must follow the Control of Asbestos Regulations, carry out appropriate risk assessments, and ensure workers are adequately trained.

What happens if asbestos is found unexpectedly during construction work?

Work in the affected area must stop immediately. The area should be secured to prevent access, and the principal contractor must be notified without delay. A licensed asbestos surveyor or contractor should be called in to assess the material and determine the appropriate course of action. Work cannot resume until the asbestos has been properly managed — whether through removal, encapsulation, or a controlled working method — and any required air monitoring has been completed.

How often should asbestos surveys be updated for CDM purposes?

There is no fixed statutory interval, but surveys should be reviewed whenever the scope of planned work changes, when new areas of a building are being accessed for the first time, or when a significant period has elapsed since the last survey. HSE guidance in HSG264 recommends that surveys are fit for purpose for the specific work being undertaken. A management survey carried out several years ago may not satisfy CDM pre-construction information requirements for an intrusive refurbishment — a new or updated survey may be needed.

Work With a Surveyor Who Understands CDM

Getting your asbestos surveys right is the foundation of CDM compliance. An incomplete or out-of-date survey doesn’t just leave you exposed to enforcement action — it puts workers at genuine risk of a disease that can take decades to manifest and has no cure.
