Asbestos at Work: How UK Law Regulates One of Britain’s Deadliest Hazards
Asbestos at work remains the single largest cause of work-related deaths in Britain. Thousands of people die every year from asbestos-related diseases — mesothelioma, lung cancer, asbestosis — and the overwhelming majority of those deaths are directly linked to occupational exposure. If you own, manage, or maintain a non-domestic building, the law places specific, enforceable duties on you. Here is what you need to know.
The Core Legislation: Control of Asbestos Regulations
The Control of Asbestos Regulations is the primary legislation governing asbestos at work across the UK. It applies to virtually all non-domestic premises and sets out clear duties for employers, building owners, contractors, and anyone responsible for managing a property where asbestos may be present.
Enforcement sits with the Health and Safety Executive (HSE), with local authorities taking responsibility for certain premises such as shops and offices. Non-compliance is not treated lightly — it can result in improvement notices, prohibition notices, unlimited fines, and criminal prosecution.
Who Does the Law Apply To?
The regulations impose obligations on several distinct parties. Understanding where you sit in that framework is the first step to genuine compliance.
- Duty holders — anyone who owns, occupies, or is responsible for the maintenance of non-domestic premises
- Employers — anyone whose workers may encounter asbestos-containing materials (ACMs) during their work
- Contractors — those carrying out work that could disturb ACMs, including builders, plumbers, electricians, and demolition teams
Domestic properties are not covered by the duty to manage. However, landlords of residential buildings still carry responsibilities under health and safety law where they control common areas or undertake maintenance work.
The Duty to Manage Asbestos at Work
One of the most important obligations under the regulations is the duty to manage asbestos. This applies to anyone responsible for maintaining or repairing non-domestic premises — from office blocks and schools to industrial units and NHS buildings.
The duty requires you to take a structured, ongoing approach:
- Find out whether asbestos is present in the building and, if so, where it is and what condition it is in
- Assess the risk — is the material damaged, deteriorating, or likely to be disturbed?
- Record the findings in an asbestos register and keep it up to date
- Produce a written asbestos management plan setting out how risks will be controlled
- Inform anyone who might disturb the material — contractors, maintenance staff, emergency services
- Review and monitor the situation regularly
The management plan is not a one-off document. It must be reviewed when conditions change — after refurbishment, if an ACM deteriorates, or if the building’s use changes significantly.
Asbestos Surveys: Where Compliance Starts
Before you can manage asbestos at work, you need to know where it is. A professional asbestos survey is the essential starting point, and there are three main types — each with a specific purpose and legal trigger.
Management Survey
A management survey is the standard survey required to fulfil the duty to manage. It identifies the location, extent, and condition of all ACMs that could be disturbed during normal occupation and routine maintenance.
The inspection is designed to be minimally intrusive — walls and ceilings are not broken into unless necessary. This is the survey most duty holders will need first, and it forms the foundation of your asbestos management plan.
Refurbishment Survey
Before any renovation, fit-out, or refurbishment work takes place, a refurbishment survey is required for the affected areas. This is a more intrusive inspection — surveyors need access to all areas where work will be carried out, including above ceilings, inside wall cavities, and beneath floors.
No refurbishment work should begin until this survey is complete. Starting work without one exposes contractors and duty holders to serious legal risk.
Demolition Survey
A demolition survey is required before any part of a building is demolished. It is the most comprehensive survey type and must cover the entire structure. All ACMs must be identified and removed before demolition begins — not during or after.
All surveys must be carried out by a competent, qualified surveyor operating to UKAS-accredited standards and in accordance with HSG264 guidance. At Supernova Asbestos Surveys, our surveyors hold recognised qualifications and have completed over 50,000 surveys nationwide.
Asbestos Licensing: Who Can Do What
Not all asbestos work is the same. The regulations divide work into three categories based on risk level, each with different legal requirements.
Licensed Work
The highest-risk asbestos work — including the removal of sprayed coatings, lagging, and asbestos insulating board (AIB) — must only be carried out by a contractor holding an HSE asbestos licence. To obtain a licence, a contractor must demonstrate technical competence, robust health and safety management systems, and suitable health surveillance arrangements for their workers.
Licences are typically valid for three years and are subject to reassessment. The HSE maintains a public register of licensed contractors — always check this before appointing anyone for asbestos removal work.
Notifiable Non-Licensed Work (NNLW)
Some asbestos tasks do not require a licence but are still notifiable to the relevant enforcing authority. This covers short-duration work on AIB or work on textured decorative coatings — such as Artex — that contain asbestos.
Before commencing NNLW, employers must:
- Notify the HSE (or relevant local authority) in advance
- Keep records of the work carried out
- Ensure workers are under medical surveillance, with examinations every three years
- Provide appropriate training and use correct control measures
Non-Licensed Work
Lower-risk asbestos tasks — such as encapsulating undamaged asbestos cement in good condition, or minor work on asbestos-containing floor tiles — may be carried out without a licence and without notification. A thorough risk assessment is still mandatory, and all workers must have received appropriate training before starting.
Asbestos Risk Assessments
Before any work that could disturb asbestos at work begins, the employer must carry out a suitable and sufficient risk assessment. This is not a box-ticking exercise — it needs to genuinely evaluate the hazard and directly inform the controls you put in place.
A proper risk assessment should consider:
- The type of asbestos present — white, brown, or blue — all are hazardous, but some more so than others
- The condition of the material — friable or damaged ACMs present significantly higher risk
- The likelihood and extent of fibre release during the planned work
- The duration and frequency of potential worker exposure
- The number of people who may be affected, including others in the building
- The adequacy of planned control measures
The findings must be recorded in writing. For licensed work, the risk assessment forms part of a written plan of work that must be prepared before work starts.
Exposure Limits and Control Measures
The regulations set a control limit for asbestos of 0.1 fibres per cubic centimetre of air, measured as a four-hour time-weighted average. There is also a short-term exposure limit of 0.6 f/cm³ over any ten-minute period.
These are legal limits, not targets. The aim should always be to reduce exposure to as low as reasonably practicable — well below the control limit wherever possible.
The hierarchy of control measures runs as follows:
- Elimination — remove the ACM entirely if practical and safe to do so
- Encapsulation or enclosure — seal or enclose ACMs that are in good condition and unlikely to be disturbed
- Engineering controls — wet methods, local exhaust ventilation (LEV), and enclosed workstations to suppress fibre release
- PPE — respiratory protective equipment (RPE) and disposable coveralls where engineering controls alone are insufficient
PPE is always the last line of defence, not the first. Relying solely on a mask and coveralls is not an acceptable approach where other controls are practicable.
Air Monitoring and Clearance Testing
During and after licensed asbestos removal work, air monitoring must be carried out by an independent UKAS-accredited analyst. Before a previously contaminated area is handed back for reoccupation, a four-stage clearance procedure must be completed — including a visual inspection and air testing to confirm fibre levels are below the clearance indicator of 0.01 f/cm³.
Skipping or rushing this stage puts occupants at risk and exposes the duty holder to serious legal liability. Do not allow a contractor to pressurise you into reopening a space before clearance is confirmed in writing.
Asbestos Training Requirements
The regulations require that all workers who are liable to encounter asbestos during their work receive appropriate information, instruction, and training. The level required depends on the nature of the work they carry out.
Asbestos Awareness Training
Anyone whose work could foreseeably disturb asbestos — builders, plumbers, electricians, joiners, painters — must receive asbestos awareness training. This covers what asbestos is, where it is commonly found, the health risks, and what to do if they suspect they have encountered it. The HSE recommends this training is refreshed annually.
Non-Licensed and Notifiable Non-Licensed Work Training
Workers carrying out non-licensed or notifiable non-licensed asbestos work need additional, more detailed training. This covers correct working methods, use of PPE, decontamination procedures, and emergency arrangements — going well beyond basic awareness.
Licensed Work Training
Workers employed by licensed contractors must undergo comprehensive training that includes supervised on-the-job instruction, detailed understanding of the plan of work, and regular refresher courses. Competence is an ongoing requirement, not a one-time certificate.
Professional Qualifications
Beyond site-level training, professionals working in asbestos surveying and analysis are expected to hold recognised qualifications. Surveyors typically hold the RSPH Level 3 Award in Asbestos Surveying, while analysts hold qualifications covering air monitoring and fibre counting. These qualifications underpin the competence standards the HSE and clients should expect when appointing a surveying firm.
Health Surveillance for Asbestos Workers
Workers involved in notifiable non-licensed work and all licensed asbestos work must be placed under medical health surveillance. This involves an initial medical examination before they begin asbestos work, followed by repeat examinations at least every three years.
Health records must be kept for a minimum of 40 years — a requirement that reflects the long latency period of asbestos-related diseases, which can take decades to manifest after exposure. This is not an administrative formality; it is a legal obligation with a direct human purpose.
Record Keeping and Documentation
Throughout all asbestos-related activities, thorough documentation is a legal requirement. Duty holders and employers must maintain:
- An up-to-date asbestos register for the premises
- A current asbestos management plan
- Records of all asbestos surveys and re-inspection reports
- Risk assessments and plans of work for asbestos tasks
- Air monitoring results
- Training records for all relevant workers
- Health surveillance records
- Waste transfer notes for asbestos waste disposal
These records must be readily accessible — HSE inspectors or local authority officers can request them at any time. Failure to produce adequate documentation is, in itself, a breach of the regulations.
HSE Enforcement and the Consequences of Non-Compliance
The HSE takes asbestos compliance seriously. Inspectors conduct both planned inspections and reactive investigations following incidents or complaints. Where breaches are identified, they have the power to issue improvement notices, prohibition notices stopping work immediately, and to prosecute individuals and organisations.
Prosecutions for asbestos offences can result in unlimited fines in the Crown Court, and custodial sentences are not uncommon in serious cases. Directors and senior managers can be held personally liable where failures stem from decisions made at a leadership level.
The reputational damage that follows an HSE prosecution can be equally damaging as the financial penalties. Getting compliance right from the outset is always the better approach.

Frequently Asked Questions
What is the duty to manage asbestos and who does it apply to?
The duty to manage asbestos applies to anyone responsible for maintaining or repairing non-domestic premises. This includes commercial landlords, facilities managers, and building owners. The duty requires you to identify whether asbestos is present, assess the risk it poses, record findings in an asbestos register, produce a management plan, and ensure that anyone who might disturb the material is informed. It does not apply to private domestic properties, though landlords of residential buildings retain responsibilities in common areas and during maintenance work.
Do I need an asbestos survey before refurbishment work?
Yes. Before any refurbishment, fit-out, or renovation work begins, a refurbishment survey must be completed for the areas affected. This is a legal requirement under the Control of Asbestos Regulations, not just best practice. The survey must be carried out before work starts — not during or after. Starting refurbishment without a survey exposes both the duty holder and the contractor to enforcement action and significant legal liability.
What is the difference between licensed and non-licensed asbestos work?
The regulations divide asbestos work into three categories. Licensed work — covering high-risk tasks such as removing sprayed coatings, lagging, or asbestos insulating board — must only be carried out by a contractor holding a current HSE asbestos licence. Notifiable non-licensed work (NNLW) covers lower-risk tasks that do not need a licence but must still be notified to the HSE or local authority in advance. Non-licensed work covers the lowest-risk tasks, which require no licence and no notification but still demand a risk assessment and appropriate worker training.
How long must asbestos health records be kept?
Health surveillance records for workers involved in notifiable non-licensed and licensed asbestos work must be retained for a minimum of 40 years. This unusually long retention period reflects the fact that asbestos-related diseases — including mesothelioma — can take 20 to 50 years to develop after exposure. The records must be kept in a format that remains accessible throughout that period.
What happens if I fail to comply with asbestos regulations at work?
Non-compliance with the Control of Asbestos Regulations can result in HSE improvement notices, prohibition notices halting work immediately, unlimited fines, and criminal prosecution. In serious cases, custodial sentences have been handed down. Directors and senior managers can face personal liability where failures arise from decisions at leadership level. Beyond the legal consequences, inadequate asbestos management puts workers, contractors, and building occupants at genuine risk of life-threatening illness.
