Asbestos at Work Regulations: What UK Employers and Workers Must Know
Asbestos kills more people in the UK each year than any other single work-related cause. The material was used extensively in buildings constructed before 2000, meaning millions of workers across construction, maintenance, and facilities management still encounter it regularly. Understanding the asbestos at work regulations that govern how employers and workers must respond is not optional — it is a legal duty with serious consequences for getting it wrong.
This post covers the key legislation, survey requirements, licensing rules, PPE obligations, decontamination procedures, health surveillance, and what employers must do right now to stay compliant.
The Core Asbestos at Work Regulations You Must Understand
Two pieces of legislation form the backbone of asbestos law in Great Britain. Both place clear, enforceable duties on employers — and ignorance of either is not a defence.
The Control of Asbestos Regulations
The Control of Asbestos Regulations is the primary legal framework for managing asbestos in UK workplaces. It sets out who is responsible, what they must do, and the standards they must meet.
Under these regulations, the workplace exposure limit for asbestos fibres is 0.1 fibres per cubic centimetre of air — a threshold that must not be exceeded under any circumstances. Exceeding this limit, or failing to monitor air quality appropriately, is a breach of the regulations and can trigger immediate enforcement action.
Regulation 4 is particularly significant. It places a duty to manage asbestos on anyone who owns, occupies, or is responsible for non-domestic premises. That means identifying whether asbestos is present, recording its location and condition, and putting a management plan in place to control the risk. Failing to comply with Regulation 4 is a criminal offence.
The regulations also distinguish between different categories of asbestos work, with the most hazardous activities requiring a licence from the Health and Safety Executive (HSE). Notifiable non-licensed work sits in a middle category — it must be reported to the relevant enforcing authority before it begins.
The Health and Safety at Work etc. Act
The Health and Safety at Work etc. Act provides the overarching framework within which the asbestos at work regulations sit. It places a general duty on employers to ensure, so far as is reasonably practicable, the health, safety, and welfare of their employees — including protecting them from exposure to hazardous substances like asbestos.
Employers must provide adequate information, instruction, and training, and must supply appropriate personal protective equipment where risks cannot be eliminated. Breaches of this Act can result in unlimited fines and, in serious cases, custodial sentences.
Courts have handed down significant penalties to employers who failed to take asbestos risks seriously. This is not a regulatory grey area.
Asbestos Surveys: A Legal Requirement Before Work Begins
Before any construction, refurbishment, or demolition work begins on a building that may contain asbestos, a survey is legally required. The type of survey depends on the nature of the work planned — getting this wrong puts workers at immediate risk and exposes duty holders to enforcement action.
The HSE’s guidance document HSG264 sets out the standards that asbestos surveys must meet. Surveys must be carried out by competent surveyors — typically those accredited by the United Kingdom Accreditation Service (UKAS) — and the results must be recorded in an asbestos register that is kept accessible to anyone who might disturb the material.
Management Surveys
A management survey is required for buildings in normal occupancy and use. Its purpose is to locate asbestos-containing materials (ACMs) that could be disturbed during routine maintenance or everyday activities. The surveyor assesses the condition of any ACMs found and assigns a risk rating to inform the management plan.
This type of survey is not intrusive — it does not involve breaking into the building fabric. However, it must cover all accessible areas, and any presumed ACMs that cannot be confirmed must be treated as if they contain asbestos until proven otherwise.
Refurbishment Surveys
A refurbishment survey is required before any refurbishment or maintenance work that could disturb the building fabric. This is a more intrusive survey — it involves accessing areas that would normally be sealed, including voids, ceiling spaces, and wall cavities. Samples are taken and sent to an accredited laboratory for analysis.
This survey must cover the specific area where work is planned, not necessarily the whole building. However, if the scope of works changes, a further survey may be needed before new areas are touched.
Demolition Surveys
A demolition survey is the most thorough of the three. It must be completed before any demolition work begins and must cover the entire structure. The surveyor will access all areas, including those that are normally inaccessible, to provide a complete picture of all ACMs present.
The findings from a demolition survey inform the asbestos removal programme that must be completed before demolition can proceed. No demolition contractor should begin work without seeing a completed demolition survey report.
Licensing and Training: Who Can Do What
Not everyone can work with asbestos. The asbestos at work regulations create a clear hierarchy based on the risk level of the work involved.
Licensed Asbestos Removal
The highest-risk asbestos work — including work with sprayed coatings, lagging, and asbestos insulating board — must be carried out by a company holding a licence issued by the HSE. Licences are not granted automatically; the HSE assesses each applicant’s competence, equipment, and safety management systems before issuing one.
Licences must be renewed every three years, and the HSE can revoke a licence at any time if a company fails to maintain the required standards. Before engaging any contractor for asbestos removal, always verify their licence status on the HSE’s public register.
For licensed work, the employer must also notify the relevant enforcing authority at least 14 days before work begins. This notification requirement exists so that inspectors can visit the site if they choose to.
Asbestos Awareness and Handling Training
The regulations require that any worker who could encounter asbestos during their work receives appropriate training. There are three levels:
- Asbestos awareness training — for workers who might accidentally disturb ACMs, such as electricians, plumbers, and decorators working in older buildings. This covers what asbestos is, where it might be found, and what to do if it is encountered.
- Non-licensed work training — for workers carrying out non-licensed asbestos work, covering safe working methods, use of PPE, and decontamination procedures.
- Licensed work training — for workers employed by licensed contractors, covering all aspects of safe asbestos removal in detail.
Refresher training is required at least every year for anyone working with or liable to disturb asbestos. The HSE can inspect training records at any time, and inadequate training is one of the most common compliance failures identified during enforcement visits.
Protecting Workers: PPE, Decontamination, and Health Surveillance
Even with the best planning and risk controls in place, workers carrying out asbestos work need robust physical protection. The asbestos at work regulations set clear requirements in three areas.
Personal Protective Equipment
Workers must be provided with appropriate respiratory protective equipment (RPE) and protective clothing before any asbestos work begins. The type of RPE required depends on the risk level of the work — licensed work typically requires a powered air-purifying respirator or self-contained breathing apparatus, while lower-risk work may permit a half-mask with a P3 filter.
Face fit testing is mandatory. An RPE that does not seal properly to the wearer’s face provides no meaningful protection. Employers must ensure that fit testing is carried out by a competent person and that records are kept.
Disposable coveralls, gloves, and boot covers complete the standard PPE package for asbestos work. Reusable clothing must never be worn into an asbestos work area unless it can be fully decontaminated before leaving the site.
Decontamination Procedures
Decontamination after asbestos work is not optional — it is a legal requirement. The purpose is to prevent fibres from being carried out of the work area on clothing, skin, or equipment, where they could pose a risk to others.
For licensed asbestos work, a three-stage decontamination unit is required on site. The process works as follows:
- Workers use a HEPA-filtered vacuum to remove loose fibres from their protective clothing before leaving the work area.
- They enter a dirty changing area, remove their disposable coveralls, and bag them for disposal as asbestos waste.
- They shower thoroughly, washing hair and body, before entering the clean changing area and putting on fresh clothing.
All asbestos waste — including used PPE, contaminated materials, and cleaning waste — must be double-bagged in clearly labelled, UN-approved waste sacks and disposed of at a licensed waste facility. Records of waste disposal must be kept.
Health Surveillance and Medical Records
Workers engaged in licensed asbestos work must be placed under medical surveillance by a doctor appointed by the HSE. This includes a baseline medical examination before they begin asbestos work and regular follow-up examinations thereafter.
Medical records for asbestos workers must be retained for 40 years. This is because asbestos-related diseases — including mesothelioma, asbestosis, and lung cancer — have extremely long latency periods. A disease diagnosed today may have resulted from exposure decades ago, and long-term records are essential for both compensation claims and epidemiological research.
Workers also have the right to access their own health records. Employers must not obstruct this right.
Employer Responsibilities: Managing Asbestos In Situ
Not all asbestos needs to be removed immediately. In many cases, ACMs that are in good condition and are not likely to be disturbed are best left in place and managed. This is often the safer and more practical option — but it still requires a structured approach.
Employers and duty holders must:
- Maintain an up-to-date asbestos register recording the location, type, and condition of all known or presumed ACMs in the building.
- Produce a written asbestos management plan setting out how identified risks will be controlled.
- Review the management plan regularly — typically every six to twelve months, or whenever there is a change in circumstances such as building works or a change of use.
- Ensure that anyone who could disturb ACMs — including maintenance contractors and cleaning staff — is informed of their location before work begins.
- Carry out periodic condition monitoring of ACMs to identify any deterioration that might increase the risk of fibre release.
The asbestos management plan is a live document, not a box-ticking exercise. It must reflect the current state of the building and the current risks. An outdated plan that has not been reviewed provides no legal protection if something goes wrong.
What Happens When the Asbestos at Work Regulations Are Breached
The HSE takes asbestos enforcement seriously. Inspectors carry out unannounced site visits, and they have the power to issue prohibition notices stopping work immediately if they find unsafe conditions. Improvement notices can require specific remedial action within a set timeframe.
Where breaches are serious, the HSE will pursue prosecution. Penalties under the Health and Safety at Work etc. Act include unlimited fines for companies and individuals, and directors or managers who are personally responsible for a breach can face prosecution in their own right.
In the most serious cases — where a worker has been killed or seriously harmed as a result of asbestos exposure — custodial sentences are available to the courts. The HSE publishes details of prosecutions and convictions on its website, and the reputational damage of appearing on that register can be as damaging as the financial penalty.
The message is straightforward: the cost of compliance is always lower than the cost of getting it wrong.

Frequently Asked Questions
Who is responsible for managing asbestos in a workplace?
Under Regulation 4 of the Control of Asbestos Regulations, the duty to manage asbestos falls on the person or organisation that owns, occupies, or has responsibility for non-domestic premises. In practice, this is usually the building owner, landlord, or facilities manager. If there is any ambiguity about who holds the duty, it should be clarified in writing before any work is carried out.
Do the asbestos at work regulations apply to small businesses?
Yes. The regulations apply to all employers and duty holders regardless of the size of the business. A sole trader carrying out maintenance work in a pre-2000 building has the same legal obligations as a large contractor. The scale of the compliance measures required may differ, but the duty itself does not.
What is the difference between licensed and non-licensed asbestos work?
Licensed work involves the highest-risk materials — such as sprayed coatings, lagging, and asbestos insulating board — and must only be carried out by a contractor holding an HSE licence. Non-licensed work covers lower-risk tasks where the exposure to asbestos fibres is short-duration and low-level. Some non-licensed work is still notifiable to the enforcing authority before it begins. If you are unsure which category your planned work falls into, seek advice from a specialist surveyor before proceeding.
How often does an asbestos management plan need to be reviewed?
There is no single prescribed interval in the regulations, but HSE guidance recommends reviewing the plan at least every six to twelve months, and also following any change in circumstances — such as building works, a change of occupier, or a change in the condition of known ACMs. A plan that is never reviewed is unlikely to satisfy an enforcement inspector.
What should a worker do if they suspect they have disturbed asbestos?
Work should stop immediately. The area should be evacuated and secured to prevent others from entering. No attempt should be made to clean up the material without specialist advice. The employer must be notified, and if the disturbance has occurred in a licensed work context, the HSE must also be informed. An air monitoring assessment may be required before the area can be re-occupied.
