Asbestos at Work: What Every Employer and Dutyholder Needs to Know
Asbestos doesn’t announce itself. It sits silently inside walls, beneath floor tiles, above suspended ceilings, and around pipe lagging — often completely undisturbed for decades. But the moment it’s touched, drilled, cut, or damaged, it releases microscopic fibres that can cause life-altering and fatal diseases. Managing asbestos at work isn’t optional for employers and those responsible for non-domestic premises — it’s a legal duty, and more importantly, it’s the difference between protecting your workforce and unknowingly putting them at serious risk.
Where Asbestos Hides in the Workplace
Asbestos-containing materials (ACMs) were used extensively in UK construction right up until 1999, when a full ban came into force. Any building constructed or refurbished before that year could contain asbestos — and in many cases, does.
In a typical commercial or industrial building, ACMs can be found in:
- Sprayed coatings on structural steelwork, ceilings, and beams
- Pipe lagging and boiler insulation
- Ceiling tiles and floor tiles
- Textured coatings such as Artex
- Roofing sheets and guttering (particularly asbestos cement)
- Insulating boards used in partition walls, door linings, and fire breaks
- Gaskets, rope seals, and friction materials in older plant and machinery
The problem is that many of these materials look completely unremarkable. There’s no way to identify asbestos by sight alone — a textured ceiling, a floor tile, or a piece of board panelling could be entirely benign, or it could contain asbestos. Only sample analysis of a physical sample taken from the material can confirm which.
Industries at Highest Risk from Asbestos at Work
While asbestos is a hazard across all sectors operating in older buildings, certain industries carry a heightened risk due to the nature of the work involved:
- Construction and refurbishment — disturbing building fabric regularly means a higher chance of inadvertent exposure
- Building maintenance — electricians, plumbers, and joiners often work in areas where ACMs are present
- Shipbuilding and heavy industry — asbestos was used extensively in these environments historically
- Automotive repair — older brake pads, gaskets, and clutch linings may contain asbestos
- Education and healthcare — many older schools and hospitals still contain significant quantities of ACMs
The risk isn’t limited to blue-collar trades. Office workers, teachers, and healthcare staff can be exposed if building fabric is disturbed during routine maintenance — often without anyone realising it at the time.
The Health Risks: What Asbestos Exposure Actually Does
There is no safe level of asbestos exposure. Even a brief, one-off encounter with airborne fibres carries some risk, and the diseases caused by asbestos are among the most serious in occupational medicine. What makes it particularly cruel is the latency period — symptoms often don’t appear until 20 to 50 years after exposure.
Asbestosis
Asbestosis is a chronic, progressive lung disease caused by the inhalation of asbestos fibres over a sustained period. The fibres embed in lung tissue and cause scarring — a process called fibrosis — which gradually reduces the lungs’ ability to function. Symptoms include a persistent dry cough, increasing breathlessness, and chest tightness. There is no cure; treatment focuses on managing symptoms and slowing deterioration.
Pleural Disease
Exposure to asbestos can also cause changes to the pleura — the lining surrounding the lungs. Pleural plaques are the most common asbestos-related condition and, while generally benign themselves, indicate that significant past exposure has occurred. Pleural thickening is more serious and can restrict lung expansion, causing breathlessness.
Lung Cancer
Asbestos is a recognised cause of lung cancer, and the risk is compounded significantly by smoking. Workers who have been exposed to asbestos and who smoke face a substantially higher risk than either risk factor in isolation — the two interact in a way that multiplies rather than simply adds to the overall risk. Asbestos-related lung cancer is often diagnosed at an advanced stage, when treatment options are more limited.
Mesothelioma
Mesothelioma is the disease most closely associated with asbestos at work. It is a cancer of the mesothelium — the thin membrane lining the lungs, chest cavity, abdomen, and heart — and it is almost exclusively caused by asbestos exposure. Its latency period — often 30 to 50 years — means that people exposed during their working years in the 1970s and 1980s are still being diagnosed today.
Mesothelioma is currently incurable, and prognosis remains poor for most patients. The UK has one of the highest rates of mesothelioma in the world, a direct legacy of the heavy industrial use of asbestos throughout the twentieth century. The Health and Safety Executive continues to highlight asbestos as the single greatest cause of work-related deaths in the country.
Your Legal Duties as a Dutyholder
If you own, manage, or have maintenance responsibilities for a non-domestic building, the Control of Asbestos Regulations place a legal duty on you to manage the risk from asbestos at work. This is commonly referred to as the “duty to manage.”
In practical terms, this means you must:
- Take reasonable steps to identify whether asbestos is present in your premises
- Assess the condition of any ACMs found and the risk they present
- Prepare and implement a written asbestos management plan
- Keep records up to date and share relevant information with anyone who might disturb the fabric of the building — including contractors
- Review and monitor the plan regularly
Before any refurbishment or demolition work begins, a more detailed survey is required — one that involves intrusive inspection of the areas to be disturbed. You cannot rely on a management survey alone before committing to building work.
Failure to comply with these duties is a criminal offence. The HSE has enforcement powers that include prohibition notices, improvement notices, and prosecution. Employers and dutyholders have faced custodial sentences for serious breaches — not just financial penalties.
What About Domestic Properties?
The duty to manage under the Control of Asbestos Regulations applies specifically to non-domestic premises. However, landlords of residential properties have responsibilities under other health and safety legislation, and any landlord undertaking refurbishment work on a pre-2000 property should commission an appropriate survey before work commences.
The Different Types of Asbestos Survey — and When You Need Each One
Not all asbestos surveys are the same. Using the wrong type of survey for your situation can leave you legally exposed and your workers unprotected. Here’s what each survey covers and when it’s required.
Management Survey
A management survey is the standard survey for occupied premises in normal use. It identifies the location, extent, and condition of ACMs that might be disturbed during everyday activities, and it provides the information needed to create your asbestos management plan. It is not suitable for use before refurbishment or demolition work — a different survey type is required for that.
Refurbishment Survey
A refurbishment survey is required before any refurbishment, fit-out, or planned building works. It is intrusive — surveyors need to access all areas likely to be disturbed, which may include breaking into walls, lifting floors, and examining voids. The aim is to ensure that no asbestos is disturbed during the project without appropriate controls in place.
Demolition Survey
Before a building is demolished, a demolition survey is required. This is the most thorough and intrusive type of survey, covering the entire structure to ensure all ACMs are identified and safely managed before demolition begins. Proceeding without one is not only dangerous — it’s unlawful.
Re-inspection Survey
If you already have an asbestos management plan in place, the Control of Asbestos Regulations require you to review it periodically to ensure it remains current. A re-inspection survey allows a qualified surveyor to assess whether conditions have changed, whether any previously identified ACMs have deteriorated, and whether the management plan needs updating. Annual re-inspections are standard practice for most premises.
What Happens When Asbestos Is Found at Work
Finding asbestos in your building doesn’t automatically mean it needs to be removed. In many cases, ACMs in good condition and in locations where they’re unlikely to be disturbed are best managed in situ — monitored regularly, kept in good condition, and recorded in your management plan.
Removal is generally recommended when:
- The material is in poor condition and deteriorating
- Refurbishment or demolition work requires the area to be disturbed
- The material is in a location where repeated disturbance is unavoidable
- Removal is the most practical long-term management option
Where removal is required, it must be carried out by a licensed contractor for higher-risk materials such as sprayed coatings, lagging, and insulating board. Our asbestos removal service covers the full process, from planning through to clearance certification.
Some lower-risk materials — such as asbestos cement — may be removed by trained but unlicensed operatives, though notification and other requirements still apply under HSE guidance.
Protecting Your Workers: Practical Steps for Employers
Beyond commissioning surveys and managing records, there are practical day-to-day steps that employers and dutyholders should take to protect their workforce from asbestos at work.
- Always check your asbestos register before work begins. Contractors must be shown the relevant section of your management plan before they start — every time, without exception.
- Ensure maintenance staff receive asbestos awareness training. Anyone whose work could bring them into contact with ACMs — directly or indirectly — must be trained. This is a regulatory requirement under the Control of Asbestos Regulations, not a recommendation.
- Have a clear procedure for unexpected discovery. If workers find a suspicious material they weren’t expecting, they should stop work immediately, isolate the area, and seek professional advice before proceeding.
- Commission air monitoring when appropriate. During and after asbestos removal work, air monitoring should be carried out to confirm that fibre levels are within safe limits.
- Keep your asbestos register up to date. Any changes to the building, any new information, and any re-inspection results should be incorporated promptly.
If you’re unsure whether a material contains asbestos and need a quick answer before work proceeds, a testing kit allows you to collect a sample safely, which can then be sent for laboratory analysis. It’s a practical option when you need clarity fast and a full survey isn’t immediately available.
Don’t Overlook Fire Safety Alongside Asbestos Management
Many of the same buildings that contain asbestos also require a fire risk assessment under the Regulatory Reform (Fire Safety) Order. For employers and property managers, it makes sense to address both obligations together where possible.
Supernova Asbestos Surveys offers both asbestos surveying and fire risk assessments, meaning you can manage your compliance requirements through a single, trusted provider rather than coordinating multiple contractors.

Frequently Asked Questions
Is asbestos still present in UK workplaces?
Yes — asbestos remains present in a large number of UK workplaces. Because asbestos-containing materials were used extensively in construction until 1999, any non-domestic building built or refurbished before that date may contain ACMs. The Health and Safety Executive estimates that millions of tonnes of asbestos remain in UK buildings, making asbestos at work an ongoing concern for employers and dutyholders.
Who is responsible for managing asbestos at work?
Under the Control of Asbestos Regulations, the “dutyholder” is responsible. This is typically the owner of the building, the employer, or whoever has maintenance or repair obligations for the premises — as set out in a tenancy agreement or contract. In some buildings, responsibility may be shared between multiple parties, in which case all parties must cooperate to ensure the duty to manage is fulfilled.
What should I do if I suspect I’ve disturbed asbestos at work?
Stop work immediately and evacuate the area. Do not attempt to clean up any debris yourself. Seal off the area to prevent others from entering, and contact a qualified asbestos surveyor or licensed contractor as soon as possible. The area should not be re-entered until a thorough assessment has been carried out and, if necessary, a licensed contractor has completed any required remediation and clearance testing.
How often does an asbestos management plan need to be reviewed?
The Control of Asbestos Regulations require that asbestos management plans are reviewed and kept up to date. In practice, annual re-inspections are the industry standard for most premises. Re-inspections should also be triggered by any changes to the building, any deterioration in known ACMs, or any work that has the potential to disturb asbestos-containing materials.
Can I remove asbestos myself?
In most cases, no. The Control of Asbestos Regulations require that higher-risk ACMs — including sprayed coatings, pipe lagging, and insulating board — are removed only by a contractor licensed by the HSE. Some lower-risk materials may be removed by trained but unlicensed operatives, but strict conditions apply. Attempting to remove asbestos without the appropriate licence, training, and controls in place is a criminal offence and a serious risk to health.
