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

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.
