Why Asbestos and CDM Compliance Can Mean the Difference Between Life and Death on Site
Asbestos remains the single biggest cause of work-related deaths in the UK, and construction sites are where the risk is most acute. Getting asbestos CDM building strong foundation safety compliance right is not a bureaucratic exercise — it is the framework that determines whether workers go home healthy or develop a fatal lung disease decades from now. Get it wrong, and the consequences range from unlimited Crown Court fines and custodial sentences to workers developing mesothelioma 20 to 40 years after a single day’s exposure.
This post cuts through the complexity and gives you a clear, practical picture of what the regulations require, who is responsible for what, and how to stay on the right side of the law on every project.
Why Asbestos and CDM Must Work Together
Asbestos was used extensively in UK construction until its full ban in 1999. Any building constructed or refurbished before that date could contain asbestos-containing materials (ACMs) — in ceiling tiles, pipe lagging, floor tiles, roof sheets, textured coatings, and dozens of other locations.
The Construction (Design and Management) Regulations — universally known as CDM — exist to make construction projects safer from the very first day of planning. One of their central requirements is that asbestos risks are identified, recorded, and communicated before any physical work begins.
These two regulatory frameworks are not separate concerns. They are designed to work together, and every duty holder on a construction project needs to understand how they interact. Treating them as standalone obligations is one of the most common — and most dangerous — mistakes made on UK construction sites.
The Three Regulations You Need to Understand
The Control of Asbestos Regulations
The Control of Asbestos Regulations set out the legal framework for managing asbestos in buildings and at work. They cover who can carry out asbestos work, how records must be kept, and what training workers require.
Certain high-risk activities — such as removing sprayed asbestos coatings or asbestos insulation — can only be carried out by HSE-licensed contractors. Lower-risk tasks may be undertaken by non-licensed workers, but strict notification and record-keeping requirements still apply.
The regulations also impose a duty to manage asbestos in non-domestic premises. This sits with the person who has control of the building — typically the owner or the organisation responsible for maintenance. They must arrange an asbestos management survey to locate and assess any ACMs, keep an up-to-date asbestos register, and ensure that information is shared with anyone who could disturb those materials.
Construction (Design and Management) Regulations
CDM places duties on clients, principal designers, principal contractors, and individual contractors. Health and safety — including asbestos risk — must be considered at every stage of a project, from initial design through to completion.
Principal designers are responsible for coordinating pre-construction health and safety information. This includes gathering existing asbestos survey data and ensuring it is included in the pre-construction information pack passed to the principal contractor.
Principal contractors must then use that information to develop a construction phase plan that addresses how asbestos risks will be managed on site. Workers must be made aware of any known ACMs before they start work in any area.
Control of Substances Hazardous to Health Regulations (COSHH)
COSHH regulations apply wherever workers may be exposed to hazardous substances, including asbestos fibres. Employers must carry out risk assessments, implement appropriate controls, provide suitable personal protective equipment, and monitor workers’ health where exposure is a concern.
COSHH is particularly relevant in situations where the Control of Asbestos Regulations may not directly apply — for example, during certain maintenance activities in domestic properties. All three frameworks apply simultaneously and reinforce each other. Relying on one and ignoring the others is not a defensible position.
Roles and Responsibilities: Who Is Accountable for What
Clients
Under CDM, the client — the person or organisation commissioning the work — carries significant responsibility. Before any project begins, they must provide pre-construction information to the design and construction teams, and this must include any known asbestos survey data for the building.
If no survey has been carried out, the client should commission one before work starts. Handing a contractor a building without asbestos information is not just poor practice — it could expose the client to serious legal liability if a worker is subsequently harmed.
Principal Designers
Principal designers must identify foreseeable construction phase risks during the design stage and take steps to eliminate or reduce them. Asbestos is one of the most significant foreseeable risks in any project involving a pre-2000 building.
They should review existing asbestos surveys, flag any areas where refurbishment or demolition survey work is needed, and ensure that design decisions do not unnecessarily increase workers’ exposure to ACMs. If a design requires penetrating a wall or ceiling that contains asbestos, that risk must be flagged and addressed before work begins.
Principal Contractors
Principal contractors are responsible for managing the construction phase. They must ensure that all contractors on site are aware of asbestos risks in the areas where they are working, and that appropriate controls are in place before any potentially disturbing work begins.
This includes maintaining a clear site induction process that covers asbestos, ensuring that licensed removal contractors are used where required, and keeping records of all asbestos-related work carried out during the project.
Property Owners and Landlords
For non-domestic properties, the duty to manage asbestos falls on whoever has control of the premises. They must ensure a management survey has been carried out, keep the asbestos register up to date, and make that information available to anyone who could disturb ACMs — including maintenance contractors, emergency services, and tenants carrying out their own works.
Regular reinspections are also required to check that known ACMs remain in good condition. If materials are found to be damaged or deteriorating, prompt action is needed — whether that means encapsulation, repair, or asbestos removal.
Asbestos Surveys: The Starting Point for Every Project
No construction or refurbishment project on a pre-2000 building should start without an appropriate asbestos survey. The type of survey required depends on the nature of the work planned.
Management Surveys
A management survey is the standard survey for occupied buildings. It identifies the location, extent, and condition of ACMs that could be disturbed during normal occupation and routine maintenance. The results form the basis of the asbestos register and management plan.
If you manage a commercial property and do not yet have a current management survey in place, you are likely already in breach of your legal duty to manage asbestos. Getting one commissioned should be an immediate priority — not something to schedule for next quarter.
Refurbishment and Demolition Surveys
Where intrusive work is planned — anything from a kitchen refit to a full structural demolition — a demolition survey is required. This is a more intrusive investigation that involves accessing areas not normally disturbed, including voids, floor spaces, and structural elements.
This type of survey must be completed before any refurbishment or demolition work begins. It cannot be carried out while the building is occupied, as it requires destructive inspection techniques. The results must be included in the pre-construction information provided to contractors under CDM.
Asbestos Sampling and Testing
Where materials are suspected to contain asbestos but cannot be confirmed visually, samples must be taken and analysed by an accredited laboratory. Only then can the material be confirmed as an ACM and managed accordingly.
Surveyors should never assume a material is safe without proper testing. HSG264 — the HSE’s guidance on asbestos surveying — is clear that assumptions about material composition are not acceptable where there is a reasonable likelihood of asbestos being present.
Asbestos Risk Assessments: What They Must Cover
Before any work that could disturb ACMs, a specific asbestos risk assessment must be carried out. This is separate from the general CDM risk assessment and must address the specific materials present, the nature of the work, and the controls required to protect workers.
The risk assessment must be documented and made available to all workers who could be affected. It should cover:
- The location and condition of ACMs in the work area
- The likelihood of fibre release during the planned activity
- The level of exposure workers could experience
- The control measures to be implemented
- The personal protective equipment (PPE) required
- Emergency procedures in the event of accidental disturbance
Risk assessments must be reviewed and updated if circumstances change — for example, if additional ACMs are discovered during the work. A risk assessment prepared at the start of a project is not automatically valid for the entire duration if conditions on site evolve.
Training Requirements: Who Needs It and What It Must Cover
All workers who could encounter asbestos in the course of their work must receive appropriate training. This is a legal requirement under the Control of Asbestos Regulations, and it applies to a much wider group than most employers realise.
It is not just asbestos removal contractors who need training. Electricians, plumbers, joiners, painters, and general maintenance workers all need to understand:
- What asbestos is and where it is commonly found
- The health risks associated with asbestos exposure
- How to identify materials that may contain asbestos
- What to do if they suspect they have found or disturbed asbestos
- The correct use of PPE
- Emergency procedures
Training must be refreshed regularly — typically on an annual basis — to ensure workers remain up to date with current guidance and best practice. Records of training must be maintained and must be available for inspection.
Enforcement and the Real Consequences of Getting This Wrong
The Health and Safety Executive takes asbestos compliance seriously, and enforcement action is not uncommon. Inspectors carry out both planned and unannounced site visits, and they have wide powers to issue improvement notices, prohibition notices, and prosecute duty holders.
Penalties for asbestos-related offences can be severe:
- In magistrates’ courts, fines can reach £20,000 per offence
- In the Crown Court, fines are unlimited
- Individuals — including site managers and company directors — can face custodial sentences of up to two years
- Prohibition notices can shut down a site immediately, with significant financial consequences
Beyond the legal penalties, there is the human cost. Asbestos-related diseases — including mesothelioma, asbestosis, and asbestos-related lung cancer — have long latency periods. Workers exposed today may not develop symptoms for 20 to 40 years. By the time the disease appears, it is almost always fatal.
No project deadline and no cost saving is worth that risk.
A Practical Compliance Checklist for Your Next Project
If you are a client, contractor, or property manager dealing with a pre-2000 building, work through this checklist before any physical work begins:
- Commission the right survey. A management survey for ongoing occupation; a refurbishment or demolition survey before any intrusive work. Do not start work without one.
- Build asbestos information into pre-construction information. Principal designers must ensure survey data is included in the information pack passed to the principal contractor. This is a CDM requirement, not optional.
- Develop a construction phase plan that addresses asbestos. Principal contractors must document how asbestos risks will be managed on site before work begins.
- Carry out a specific asbestos risk assessment. This must be completed for every area where ACMs could be disturbed, and it must be reviewed if site conditions change.
- Ensure all workers are trained. Check that every person on site who could encounter asbestos has received appropriate training and that records are in place.
- Use licensed contractors where required. High-risk asbestos work can only be carried out by HSE-licensed contractors. Verify licences before work begins.
- Keep records. Maintain records of surveys, risk assessments, training, licensed work notifications, and any ACMs discovered or removed during the project.
- Update the asbestos register. Once the project is complete, ensure the building’s asbestos register reflects any changes — materials removed, encapsulated, or newly identified.

Frequently Asked Questions
Does CDM apply to small refurbishment projects involving asbestos?
Yes. CDM applies to virtually all construction work, including small refurbishments. Even on minor projects, if the building was constructed before 2000, asbestos risks must be assessed and communicated before work begins. The scale of CDM duties varies depending on the project, but the obligation to manage asbestos does not disappear on smaller sites.
What type of asbestos survey is needed before a refurbishment?
A refurbishment and demolition survey is required before any intrusive work begins. This is more thorough than a standard management survey and involves accessing areas that would not normally be disturbed. It must be completed before the building is handed over to contractors, as it requires destructive inspection techniques that are not compatible with occupied premises.
Who is responsible for providing asbestos information under CDM?
The client is responsible for providing pre-construction information, which must include any existing asbestos survey data. The principal designer then coordinates this information and ensures it reaches the principal contractor. If no survey exists, the client should commission one before the project proceeds. Passing a building to contractors without asbestos information is a potential breach of CDM duties.
Can a principal contractor start work before an asbestos survey is complete?
No — not in any area where ACMs could be present. Starting work in a pre-2000 building without an appropriate survey in place puts workers at risk and exposes the principal contractor and client to significant legal liability. The survey results must feed into the construction phase plan before physical work in affected areas begins.
How often does an asbestos management plan need to be reviewed?
The Control of Asbestos Regulations require the asbestos management plan to be reviewed and, where necessary, revised at regular intervals. In practice, this typically means an annual review as a minimum, plus a review whenever there is a change of circumstances — such as a change in the condition of known ACMs, new materials being discovered, or planned works that could disturb existing materials.
