Control of Asbestos Regulations 2012 explained
The Control of Asbestos Regulations 2012 (CAR 2012) consolidated and replaced all previous UK asbestos legislation into a single framework. It applies to all work with asbestos-containing materials in England, Scotland, and Wales. Northern Ireland has parallel regulations.
CAR 2012 covers:
- The duty to manage asbestos in non-domestic buildings (Regulation 4)
- Requirements for asbestos surveys before refurbishment or demolition (Regulation 7)
- The licensing system for high-risk asbestos work (Regulations 8–9)
- Training requirements for anyone who might encounter asbestos at work (Regulation 10)
- Exposure limits — the workplace exposure limit (WEL) is 0.1 fibres per cm³ of air, averaged over 4 hours
- Health surveillance and medical records for exposed workers
The regulations apply to employers, building owners, landlords, and self-employed workers. Domestic homeowners working on their own property are technically exempt from CAR 2012's employer duties — but are still subject to environmental and waste disposal regulations.
The duty to manage (Regulation 4)
Regulation 4 is the cornerstone of UK asbestos law. It places a legal duty on the person responsible for maintaining or repairing a non-domestic building to manage the asbestos in it. This person is called the duty holder.
Who is the duty holder?
- The building owner, if they have a maintenance or repair obligation (usually through the lease)
- The tenant, if the lease gives them maintenance responsibility
- The managing agent, if they've been contracted to manage the building
The duty holder must:
- Find out whether asbestos is present — through a management survey or by checking existing records
- Presume materials contain asbestos unless there's strong evidence they don't
- Assess the condition of any asbestos-containing materials found
- Make a written plan to manage the risk — an asbestos management plan
- Inform anyone who might work on or disturb the asbestos — contractors, maintenance staff, emergency services
- Monitor the condition of ACMs and review the plan regularly
Domestic homes are not covered by Regulation 4 — but the moment a home becomes a rental property or a commercial premises, the duty applies. For survey costs and options, see our asbestos survey guide.
Licensed vs non-licensed vs NNLW
CAR 2012 divides asbestos work into three categories. Getting this wrong is a criminal offence.
| Category | What it covers | Requirements |
|---|---|---|
| Licensed work | Sprayed asbestos, pipe/boiler lagging, asbestos insulating board in poor condition | HSE licence, 14-day notification, medical surveillance, full containment, 4-stage clearance |
| NNLW (Notifiable Non-Licensed Work) | Short-duration work with certain ACMs (e.g. AIB in good condition, some textured coatings) | ASB5 notification to HSE, brief written assessment, health records kept 40 years |
| Non-licensed work | Cement products (roofing, floor tiles, soffits), textured coatings in good condition, gaskets | Risk assessment, method statement, trained workers, proper PPE, safe disposal |
The distinction matters financially. Licensed removal costs roughly double non-licensed work because of the containment, notification, and clearance requirements. For a cost breakdown, see our removal cost guide.
Penalties for non-compliance
The HSE doesn't mess around with asbestos enforcement. Penalties under CAR 2012:
- Failure to manage asbestos (Reg 4): Improvement notice, then prosecution. Fine: unlimited.
- Unlicensed removal of licensable material: Criminal offence. Fine: unlimited. Imprisonment: up to 2 years.
- Failure to notify HSE before licensed work: Criminal offence. Fine: unlimited.
- Improper disposal of asbestos waste: Fine: unlimited under the Environmental Protection Act 1990.
In 2023–2024, the HSE prosecuted over 40 cases involving asbestos offences, with fines ranging from £5,000 to over £1 million for serious breaches. Companies and individuals can both be prosecuted.
Beyond criminal penalties, civil claims for asbestos-related disease are common. The average mesothelioma compensation payout in the UK exceeds £150,000, and employers' liability claims can run into millions.
Landlord and homeowner responsibilities
Landlords
If you rent out a property built before 2000, you are the duty holder for communal areas under Regulation 4. That means:
- A management survey of communal areas (hallways, stairwells, boiler rooms)
- An asbestos register listing all ACMs found
- A written management plan
- Informing contractors before they work on the building
- Annual condition checks
For individual flats within a building, the duty typically falls on whoever has maintenance responsibility under the lease — usually the freeholder or management company.
Homeowners
Domestic homeowners working on their own property are not directly covered by CAR 2012's employer provisions. But you are still subject to:
- Environmental Protection Act 1990 — illegal to dispose of asbestos waste improperly
- Hazardous Waste Regulations 2005 — asbestos is classified as hazardous waste
- Construction (Design and Management) Regulations 2015 — if you hire contractors, you have duties as a client
If you hire a builder to renovate your pre-2000 home and they disturb asbestos without a survey, both you (as client) and the builder can face enforcement action. Get quotes from properly licensed contractors.
