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:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

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.
