ACMs Asbestos and CDM Compliance: What Every Duty Holder Needs to Know
If your building was constructed before 2000, there is a strong chance asbestos-containing materials (ACMs) are present somewhere within its fabric. Understanding how ACMs asbestos regulations interact with the Construction Design and Management (CDM) framework is not just a legal obligation — it is the difference between a safe site and a prosecution.
Whether you are a property owner, principal contractor, or facilities manager, this post cuts through the complexity and tells you exactly what you need to know about identifying, managing, and controlling ACMs under UK law.
Understanding CDM 2015 and Its Relationship with ACMs Asbestos
The Construction Design and Management Regulations place legal duties on every party involved in a construction project — from the client commissioning the work to the workers on site. Where ACMs asbestos is concerned, CDM 2015 does not stand alone.
It works alongside the Control of Asbestos Regulations and HSE guidance document HSG264 to create a robust legal framework. CDM 2015 applies to all construction work in the UK, including minor refurbishments, full demolitions, and everything in between. There is no minimum project size that exempts you from duty.
Who Has Duties Under CDM 2015?
- Clients — must provide pre-construction information, including details of any known ACMs
- Principal Designers — must plan, manage, and coordinate health and safety during the pre-construction phase, factoring in asbestos risks
- Principal Contractors — responsible for managing the construction phase plan and ensuring ACMs are handled safely on site
- Contractors and Workers — must follow safe systems of work and report any suspected ACMs immediately
When asbestos is present, each of these roles carries specific responsibilities. Ignoring them carries serious consequences — enforcement notices, unlimited fines, and custodial sentences are all within the HSE’s powers.
The Legal Duty to Manage ACMs Asbestos in Buildings
The Control of Asbestos Regulations place a clear duty on those who own or manage non-domestic premises to identify, assess, and manage any ACMs within the building. This applies to commercial properties, public buildings, schools, hospitals, and the communal areas of residential blocks.
The duty holder must:
- Find out if ACMs are present — and presume materials contain asbestos unless there is strong evidence they do not
- Assess the condition of any ACMs and the risk they pose
- Produce and maintain an Asbestos Register documenting all findings
- Create and implement an Asbestos Management Plan
- Review the plan regularly and update it when circumstances change
- Share information with anyone who might disturb ACMs during their work
Failing to fulfil these duties is not a minor oversight. The HSE has consistently pursued prosecutions against duty holders who have neglected their obligations — and the penalties reflect how seriously asbestos exposure is treated under UK law.
What Is an Asbestos Management Plan?
An Asbestos Management Plan is a live document that records where ACMs are located in your building, their condition, the risk they present, and how they will be managed or removed. It must be reviewed at least annually and updated following any changes to the building or its use.
The plan should be accessible to contractors, maintenance staff, and emergency services — anyone whose work could potentially disturb asbestos materials. Keeping it locked in a filing cabinet and never sharing it defeats the purpose entirely.
Asbestos Surveys: The Starting Point for CDM Compliance
Before any construction, refurbishment, or demolition work begins, the right type of asbestos survey must be commissioned. HSG264 sets out the types of survey required and when each applies. Getting this wrong — or skipping the survey entirely — puts workers at serious risk and exposes you to significant legal liability.
Management Survey
A management survey is the standard survey required for all non-domestic premises during their normal occupation and use. It locates ACMs that could be disturbed during routine maintenance and checks their condition.
This survey forms the basis of your Asbestos Register and Management Plan. It is not a one-off exercise — as the building changes, the survey findings must be kept current.
Refurbishment Survey
A refurbishment survey is required before any refurbishment or intrusive maintenance work takes place. It is more invasive than a management survey because it needs to locate all ACMs in areas that will be disturbed during the works.
This survey must be completed before the project begins — not during it. Commissioning it retrospectively, once work is already underway, is a common and costly mistake that can halt an entire project.
Demolition Survey
A demolition survey is the most thorough of all three types. It is required before any structure is demolished in full or in part, and must locate all ACMs throughout the entire building — including areas that are normally inaccessible.
All ACMs must be removed before demolition proceeds. There are no shortcuts here, and no planning authority or principal contractor should allow demolition to begin without a completed survey in place.
Where ACMs Asbestos Is Commonly Found in Buildings
Asbestos was used extensively in UK construction from the 1950s through to the late 1990s. Its properties — fire resistance, durability, and insulating capability — made it popular across a huge range of building materials. If your property was built or refurbished during this period, ACMs could be almost anywhere.
Common Locations for ACMs
- Pipe and boiler lagging (thermal insulation)
- Sprayed coatings on structural steelwork, ceilings, and walls
- Ceiling tiles and floor tiles (including the adhesive beneath vinyl tiles)
- Textured decorative coatings such as Artex
- Insulation boards in partition walls and around fire doors
- Roofing sheets, gutters, and downpipes made from asbestos cement
- Water tanks and cisterns in roof spaces
- Old electrical panels and fuse boxes
- Rope seals and gaskets around boilers and heating systems
- Soffit boards and external cladding panels
These materials are not always visually obvious. A trained, accredited surveyor will know where to look and how to sample materials safely for laboratory analysis.
The Presumption Rule
HSE guidance is clear: if you cannot confirm that a material does not contain asbestos, you must presume it does and manage it accordingly. This is not a precautionary suggestion — it is a legal requirement under the Control of Asbestos Regulations.
Do not allow contractors to disturb suspect materials without a survey result confirming they are safe. The consequences of getting this wrong extend far beyond regulatory penalties — asbestos-related diseases are irreversible.
Risk Assessment for ACMs Asbestos
Once ACMs have been identified, a risk assessment must be carried out to determine how they should be managed. This assessment considers several factors:
- The type of asbestos present — chrysotile, amosite, and crocidolite all carry risk, though the level varies
- The condition of the material — is it friable, damaged, or deteriorating?
- The likelihood of disturbance during normal building use or planned works
- The potential for fibre release if the material is disturbed
- Who might be exposed and how frequently
The outcome of the risk assessment determines whether ACMs should be left in place and monitored, encapsulated, or removed by a licensed contractor. Not all asbestos needs to be removed immediately — but all of it needs to be managed.
Licensed vs. Non-Licensed Work
The Control of Asbestos Regulations distinguish between licensed, notifiable non-licensed, and non-licensed asbestos work. Most work involving high-risk materials such as sprayed coatings, lagging, and insulation board requires a licensed contractor.
Only the HSE can grant an asbestos licence, and you should always verify a contractor’s licence before they begin work. Using an unlicensed contractor for licensed work is a criminal offence — not just a breach of contract.
Asbestos Awareness Training Under CDM
CDM 2015 requires that all workers involved in construction have the skills, knowledge, and training necessary to carry out their work safely. Where ACMs asbestos is a potential hazard, asbestos awareness training is not optional — it is a legal requirement for anyone who could encounter asbestos during their work.
Who Needs Asbestos Awareness Training?
- Builders, plasterers, and general construction workers
- Plumbers, electricians, and heating engineers
- Maintenance and facilities management staff
- Site managers and supervisors
- Building owners and property managers with responsibility for occupied premises
- Architects and designers working on pre-2000 buildings
The level of training required varies by role. Workers who might disturb ACMs incidentally need awareness-level training. Those who carry out licensed asbestos work require far more detailed, regulated training.
What Awareness Training Covers
A proper asbestos awareness course will cover the health risks associated with asbestos exposure, how to recognise potential ACMs, what to do if suspect materials are found, and the legal framework governing asbestos management.
It does not qualify someone to work with or remove asbestos — it teaches them to stop work and report immediately. This distinction is critical. Disturbing ACMs without proper controls in place can cause fibre release that affects not just the individual worker, but everyone in the building.
Safe Handling, Storage, and Disposal of ACMs Asbestos
Where removal of ACMs is necessary, strict procedures must be followed to protect workers, building occupants, and the surrounding environment. The HSE sets out detailed requirements for each stage of the process.
During Removal
- The work area must be sealed and clearly signed as an asbestos exclusion zone
- Workers must wear appropriate respiratory protective equipment (RPE) and disposable coveralls
- Materials should be kept damp where possible to suppress fibre release
- Air monitoring must be carried out during and after licensed removal work
- A four-stage clearance procedure must be completed before the area is reoccupied
Waste Disposal
Asbestos waste is classified as hazardous waste under UK law. It must be double-bagged in clearly labelled UN-approved sacks, transported by a registered waste carrier, and disposed of at a licensed hazardous waste facility.
Fly-tipping asbestos waste is a serious criminal offence with severe penalties. Your licensed contractor should handle all waste documentation, including consignment notes, which must be kept for a minimum of three years.

Frequently Asked Questions
What does ACMs asbestos mean?
ACMs stands for Asbestos-Containing Materials — any material or product that contains asbestos fibres. Under UK law, materials must be presumed to contain asbestos unless tested evidence confirms otherwise. Common ACMs include insulation boards, textured coatings, ceiling tiles, pipe lagging, and asbestos cement products.
Do CDM 2015 regulations apply to asbestos work?
Yes. CDM 2015 applies to all construction work, and asbestos management is a key element of pre-construction planning. Clients must provide information about known ACMs, principal designers must factor asbestos risks into their planning, and principal contractors must ensure ACMs are handled safely throughout the construction phase.
What type of asbestos survey do I need before refurbishment?
You need a refurbishment survey before any intrusive maintenance or refurbishment work begins. This survey is more invasive than a standard management survey and must be completed before work starts — not commissioned once a project is already underway. HSG264 sets out the requirements clearly.
Does all ACMs asbestos have to be removed?
No. Not all asbestos-containing materials need to be removed immediately. If ACMs are in good condition and are unlikely to be disturbed, they can often be left in place and managed through a regular monitoring programme. Removal becomes necessary when materials are deteriorating, when refurbishment or demolition is planned, or when a risk assessment determines that in-situ management is no longer appropriate.
How do I know if a contractor is licensed to remove asbestos?
You can verify a contractor’s asbestos licence directly through the HSE’s online register of licensed asbestos contractors. A valid licence must be in place before any licensed asbestos removal work begins. Using an unlicensed contractor for work that legally requires a licence is a criminal offence under the Control of Asbestos Regulations.
