Who Is Responsible for Managing the Risk of Asbestos in the Construction Industry?
Asbestos remains the single biggest cause of work-related deaths in the UK. It is present in millions of buildings constructed before 2000, and construction workers disturb it every single day — often without realising it. Understanding who is responsible for managing the risk of asbestos is not a matter of box-ticking. It is a legal obligation with serious consequences when it goes wrong.
The answer is not simple. Responsibility is shared across employers, employees, dutyholders, and the Health and Safety Executive (HSE). Each party carries distinct legal duties, and when those duties overlap, no one gets to pass the buck.
The Legal Framework That Governs Asbestos Risk
The Control of Asbestos Regulations
The Control of Asbestos Regulations is the primary legislation governing asbestos management in Great Britain. It applies to anyone who owns, manages, or works in non-domestic premises — and to employers whose workers may encounter asbestos-containing materials (ACMs).
Key duties under the Regulations include:
- Identifying whether ACMs are present before construction, refurbishment, or demolition work begins
- Carrying out a suitable and sufficient risk assessment
- Producing and maintaining an asbestos management plan
- Ensuring workers liable to disturb ACMs receive appropriate training
- Providing adequate PPE and implementing exposure controls
- Conducting air monitoring and health surveillance where required
Any building constructed before 2000 must be treated as potentially containing asbestos until proven otherwise. This is an enforceable legal obligation — not a precautionary suggestion.
The Health and Safety at Work Act
The Health and Safety at Work Act sits above all specific regulations and places a broad general duty on employers to ensure, so far as is reasonably practicable, the health, safety, and welfare of their employees. For construction employers, this means asbestos risks cannot be ignored or delegated away.
Ignorance of what a building contains is not a legal defence. Ultimate accountability sits firmly at employer level.
Employer Responsibilities: The Heaviest Burden
Employers carry the most significant share of responsibility for asbestos safety on construction sites. Before any work begins in a pre-2000 building, the right type of survey must be commissioned.
A management survey is appropriate for routine maintenance and minor works. A demolition survey is required before any intrusive refurbishment or demolition work — it covers all areas of the building, including voids, ducts, and structural elements that a standard survey would not access.
Relying on an outdated or inadequate survey puts workers at immediate risk and exposes the employer to significant legal liability.
Risk Assessment and Management Planning
Once ACMs have been identified, employers must produce a written risk assessment and an asbestos management plan. That plan must clearly state:
- Where ACMs are located and what condition they are in
- What work is planned near or involving those materials
- What control measures are in place
- Who is responsible for implementing and reviewing those measures
- How workers will be informed of the risks
This is a live document. It must be reviewed and updated whenever site conditions change, when new ACMs are discovered, or following any incident involving asbestos disturbance.
Training: Mandatory, Not Optional
All construction workers who could encounter asbestos must receive asbestos awareness training as a minimum. Workers need to understand what asbestos looks like, where it is commonly found, the health risks it presents, and what to do if they suspect they have encountered it.
Workers carrying out non-licensable asbestos work require additional Category B training. Those undertaking licensable work — which includes higher-risk materials such as asbestos insulation, insulating board, and sprayed coatings — must work for an HSE-licensed contractor and hold appropriate licensed contractor training.
Supervisors and site managers need advanced training that goes beyond awareness. They must know how to interpret asbestos surveys and management plans, implement control measures, and respond when unexpected ACMs are found. A supervisor who cannot read and enforce the asbestos management plan they are responsible for is a liability risk for the whole site.
PPE and Decontamination
Where asbestos work is being carried out, employers must provide appropriate PPE at no cost to the worker. This typically includes:
- Disposable coveralls (Type 5/6 minimum) to prevent fibre contamination
- Appropriate respiratory protective equipment (RPE), with the grade depending on the type of work
- Gloves and boot covers where relevant
PPE must be the correct specification, properly maintained, and workers must be trained in how to don and doff it safely. The removal process is where many exposures occur — it is routinely overlooked.
Construction sites where asbestos work is taking place must also have adequate decontamination facilities: designated areas for removing and bagging contaminated PPE, washing facilities, and HEPA-filtered vacuum equipment. Asbestos waste must be double-bagged, correctly labelled, and disposed of as hazardous waste by an approved contractor.
Employee Responsibilities: Workers Are Not Off the Hook
Responsibility does not rest solely with employers. Employees have their own legal duties under both the Health and Safety at Work Act and the Control of Asbestos Regulations.
Workers are required to:
- Use the PPE and RPE provided to them correctly and consistently
- Follow the asbestos management plan and any site-specific method statements
- Report any suspected ACMs — including unexpected finds — to their supervisor immediately
- Attend mandatory asbestos awareness training and any required refresher sessions
- Participate in health surveillance programmes where required
- Not undertake any work that is beyond their level of training or competency
Self-employed contractors working on construction sites carry the same duties as employed workers. Being self-employed does not remove the obligation to follow safe systems of work or to report asbestos finds.
The single most important action any construction worker can take is to stop work immediately if they disturb a material they suspect may contain asbestos. The area must be vacated, nobody should re-enter until the material has been assessed, and the supervisor must be informed straight away.
Dutyholder Responsibilities: The Building Owner’s Role
In non-domestic premises, the Control of Asbestos Regulations places a specific duty to manage asbestos on the dutyholder — typically the owner, landlord, or facilities manager responsible for maintaining the building. In a construction context, this creates a shared responsibility between the building owner and the principal contractor.
The dutyholder must:
- Know whether ACMs are present in the premises
- Maintain an up-to-date asbestos register
- Ensure that anyone working on the building — including all contractors — is made aware of where ACMs are located and their condition
- Commission refurbishment or demolition surveys before intrusive work is commissioned
Handing a construction team access to a building without providing them with an asbestos survey and register is a serious breach of the Regulations. The dutyholder does not escape liability simply because the employer of the workers failed to check.
The Role of the HSE in Asbestos Enforcement
The Health and Safety Executive is the UK’s national regulator for workplace health and safety. Its role in asbestos covers enforcement, guidance, and licensing.
Enforcement Powers
HSE inspectors carry out unannounced site inspections and respond to complaints and incidents. They have the power to issue improvement notices, prohibition notices, and prosecution. Where asbestos regulations are breached, the consequences can include:
- Unlimited fines in the Crown Court
- Custodial sentences for individuals in the most serious cases
- Revocation of asbestos removal licences
- Prohibition of ongoing work until breaches are remedied
Employers should not assume that because asbestos exposures do not cause immediate visible symptoms, the risks will go unnoticed or unpenalised. The HSE takes asbestos enforcement seriously, and prosecutions are publicly reported.
Licensing Requirements
Any company carrying out licensable asbestos work must hold a current licence issued by the HSE. This licence is not automatically granted — it requires evidence of competent management, trained operatives, appropriate insurance, and compliant procedures. Licences are subject to renewal and can be suspended or revoked where standards slip.
When appointing a contractor for asbestos removal, always verify their HSE licence number before any work begins. Do not take their word for it — check the HSE’s public register.
Guidance and Resources
The HSE publishes extensive guidance on asbestos management, including HSG264 on surveying and sampling, training requirements, and the distinction between licensable and non-licensable work. This guidance is freely available and should be the starting point for any employer developing an asbestos management approach.
Health Surveillance and Air Monitoring
Health Surveillance Requirements
Workers engaged in licensable asbestos work must be placed under a health surveillance programme supervised by an appointed doctor. This involves periodic medical examinations to detect early signs of asbestos-related disease. Records must be kept and are the employer’s responsibility to maintain.
For workers carrying out non-licensable asbestos work, employers must keep records of the work carried out, the materials involved, and the exposure levels. These records must be retained for 40 years.
Air Monitoring
During and after asbestos removal or disturbance work, air monitoring measures fibre concentrations in the environment. This determines whether control measures are working and whether it is safe for workers or building occupants to re-enter an area.
Air monitoring must be carried out by a competent person using accredited methods. The results feed directly into the risk assessment and management plan — they are not a formality.
What to Do When Unexpected Asbestos Is Found
Unexpected discovery of ACMs during construction work is common — particularly in older buildings where previous surveys may have been incomplete or where materials were concealed behind later finishes.
When this happens, the procedure is non-negotiable:
- Stop work immediately in the affected area
- Prevent anyone from entering the zone
- Report the find to the site supervisor and dutyholder
- Do not attempt to remove or disturb the material unless licensed and equipped to do so
- Commission sample analysis or a survey to confirm the presence and type of asbestos
- Update the risk assessment and management plan before work resumes
Speed matters, but so does doing it correctly. Rushing back into work without confirming what you are dealing with is how workers get exposed.

Who Is Responsible for Managing the Risk of Asbestos? Shared Accountability in Practice
Asbestos safety in the construction industry is not the sole responsibility of any one party. Employers, employees, dutyholders, and contractors all carry specific legal duties — and those duties overlap in ways that mean multiple parties can be found liable when something goes wrong.
A dutyholder who fails to commission a survey, an employer who fails to provide training, a supervisor who ignores an unexpected find, and a worker who fails to report a suspected ACM — each of these failures can contribute to an exposure event. And each of these parties can face regulatory action as a result.
The practical implication is this: everyone on a construction site has skin in the game. The dutyholder must provide an accurate asbestos register. The employer must commission the right surveys, train their workforce, and implement proper controls. The supervisor must enforce those controls on the ground. And every worker must follow safe systems of work and report anything suspicious immediately.
When each party fulfils their role, asbestos risks can be managed effectively. When one party fails, the entire system breaks down — and the consequences can be fatal, even if the effects are not felt for decades.

Frequently Asked Questions
Who is legally responsible for managing the risk of asbestos on a construction site?
Responsibility is shared between several parties. The dutyholder — typically the building owner or facilities manager — must maintain an asbestos register and provide it to contractors before work begins. The employer is responsible for commissioning appropriate surveys, training workers, and implementing control measures. Individual workers also carry legal duties to follow safe systems of work and report suspected ACMs. No single party bears sole responsibility; all must fulfil their role under the Control of Asbestos Regulations.
What type of asbestos survey is required before construction or demolition work?
A refurbishment and demolition survey is required before any intrusive construction, refurbishment, or demolition work. This type of survey is more thorough than a management survey — it accesses voids, structural elements, and concealed areas to locate all ACMs that could be disturbed during the works. A management survey alone is not sufficient for intrusive projects.
What should a worker do if they discover suspected asbestos during construction work?
Stop work immediately and vacate the area. Do not attempt to remove, disturb, or sample the material yourself. Report the find to your site supervisor and the dutyholder straight away. The material must be assessed — through sample analysis or a survey — before work can resume. Returning to work without confirmation of what the material is puts everyone at risk and may breach the Control of Asbestos Regulations.
Does the duty to manage asbestos apply to domestic properties?
The duty to manage under the Control of Asbestos Regulations applies specifically to non-domestic premises. However, employers whose workers enter domestic properties to carry out construction or maintenance work still have a duty to ensure those workers are not exposed to asbestos. If there is any reason to suspect ACMs are present in a domestic property, appropriate surveys and risk assessments should still be carried out before work begins.
How long must asbestos exposure records be kept?
Records relating to workers who have carried out licensable asbestos work must be retained for 40 years. For non-licensable asbestos work, employers must also keep records of the work done, the materials involved, and exposure levels. These long retention periods reflect the fact that asbestos-related diseases can take decades to develop after the initial exposure.
