Anyone who owns, lets or maintains a non-domestic building in the UK carries a legal duty to find out whether asbestos-containing materials (ACMs) are present and to manage the risk they pose. This obligation is set out in Regulation 4 of the Control of Asbestos Regulations 2012, widely known as the "Duty to Manage Asbestos". It applies to commercial landlords, freeholders, managing agents, facilities managers, employers, property owners, building maintenance teams, and those responsible for communal areas in blocks of flats. Non-compliance can trigger enforcement action, prosecution, fines and — most seriously — exposure of workers, contractors and tenants to a substance that remains a major cause of occupational disease in the UK.
Asbestos was fully banned in the UK in November 1999, making it illegal to import, buy or sell the material from that date. Buildings constructed before that threshold — particularly anything built before 2000 — may still contain legacy ACMs that were never removed. The UK's Health and Safety Executive (HSE) confirms that the duty to manage covers all non-domestic premises, such as factories and shops, as well as the common parts of multi-occupancy domestic premises like purpose-built blocks of flats.
What does Regulation 4 require dutyholders to do?
According to HSE guidance, the dutyholder must work through a defined sequence of actions. These steps form the practical backbone of asbestos compliance for any building professional, from property managers to refurbishment contractors handling older fabric:
- Assess whether asbestos-containing materials are present, in what quantity, where, and in what condition
- Presume materials contain asbestos unless there is strong evidence they do not
- Create and keep up to date a record or register of the location and condition of ACMs or presumed ACMs
- Assess the risk of anyone being exposed to airborne fibres from the ACMs
- Write an asbestos management plan, put it into action, and review it at least every 12 months or sooner if necessary
- Monitor the condition of ACMs or suspected ACMs on an ongoing basis
- Provide location and condition information to anyone who may work on or disturb the materials, including emergency services
Where is asbestos typically found in older buildings?
For buildings constructed before 2000, asbestos may turn up in a wide range of construction products. Identifying these materials is usually the first practical step toward Regulation 4 compliance, commonly carried out through an asbestos management survey. Materials that may contain asbestos include:
This reflects how extensively asbestos was once used across cladding, cement products, roofing and fire-protection systems — categories that today's brandschutzsysteme and fassadenputz solutions have since replaced with non-fibrous alternatives.
Why does disturbance matter more than presence?
Asbestos is not usually dangerous when it is in good condition and left undisturbed. The risk rises sharply when ACMs are damaged, drilled, sanded, broken or otherwise disturbed during maintenance, refurbishment or demolition work. Fibres released into the air can cause serious and often fatal diseases, including mesothelioma, asbestos-related lung cancer, asbestosis and pleural thickening. Health and safety data cited by legal specialists puts the current toll at around 5,000 asbestos-related deaths every year in the UK, underlining why the duty to manage remains a live compliance issue decades after the 1999 ban rather than a purely historical matter.
Who is responsible for managing the risk day to day?
HSE guidance states that the dutyholder must identify a person within their organisation responsible for managing ACMs, and that this person must be competent — meaning they have the resources, skills, training and authority to do the job effectively. In practice, this role tends to fall to different people depending on the size of the organisation: the owner in small companies, a safety, health and environment manager in larger organisations, or a maintenance, estates or facilities manager elsewhere. Dutyholders must also provide additional training for anyone involved in parts of the asbestos management plan.
What should building owners do next?
For properties built before 2000 without an existing asbestos register, the practical starting point is a management survey to identify and record suspect materials, followed by a documented management plan that is reviewed at least annually. Buildings undergoing deconstruction or major refurbishment carry heightened risk, since disturbance — not mere presence — is what releases fibres into the air. Dutyholders who have not reviewed their asbestos records recently should treat Regulation 4 compliance as an ongoing obligation rather than a one-off survey.
