What measures have been taken to safely remove existing asbestos in buildings since the ban?

Management and Removal of Asbestos in UK Buildings: What Every Dutyholder Must Know

Asbestos doesn’t disappear just because it’s been banned. Millions of buildings across the UK still contain asbestos-containing materials (ACMs), and the management and removal of asbestos remains one of the most pressing legal and safety obligations facing property owners, employers, and facilities managers today. If your building was constructed before 2000, this is not a historical concern — it is an active duty you are required to fulfil right now.

The UK banned the import, supply, and use of all forms of asbestos in 1999. But that ban didn’t make existing asbestos vanish. It simply shifted the responsibility: from preventing asbestos entering buildings to managing what’s already there.

Why Asbestos Remains a Live Issue in UK Buildings

Asbestos was used extensively in British construction throughout the 20th century. It was cheap, fire-resistant, and remarkably versatile — which is exactly why it ended up in everything from ceiling tiles and pipe lagging to floor tiles, roofing sheets, and textured coatings like Artex.

When asbestos fibres are disturbed and become airborne, they can be inhaled and lodge permanently in the lungs. This leads to serious and often fatal diseases including mesothelioma, asbestos-related lung cancer, and asbestosis. These conditions have a long latency period — symptoms can take decades to appear, meaning people exposed years ago are still falling ill today.

The Health and Safety Executive (HSE) consistently identifies asbestos as the single greatest cause of work-related deaths in the UK. This is not a historical problem. It is an ongoing public health issue that demands active management from every dutyholder responsible for a non-domestic building.

The Legal Framework Governing Management and Removal of Asbestos

The primary legislation in the UK is the Control of Asbestos Regulations, supported by the HSE’s technical guidance document HSG264. Together, these establish the legal duties placed on dutyholders — typically building owners or those responsible for the maintenance and repair of non-domestic premises.

The Duty to Manage

The duty to manage asbestos applies to anyone who owns, occupies, manages, or has responsibilities for non-domestic premises. This duty requires you to:

  • Find out whether ACMs are present in the building
  • Assess the condition and risk posed by any ACMs found
  • Produce and maintain an asbestos register
  • Create and implement an asbestos management plan
  • Provide information about ACMs to anyone who may disturb them
  • Review and monitor the plan regularly

Failing to comply with this duty is a criminal offence. The HSE can and does prosecute dutyholders who neglect their asbestos management responsibilities — ignorance is not a defence.

Licensing Requirements for Removal

Not all asbestos work requires a licence, but the most hazardous types do. The Control of Asbestos Regulations divide asbestos work into three categories:

  1. Licensed work — required for high-risk materials such as asbestos insulating board (AIB), sprayed coatings, and lagging. Only contractors holding a current HSE licence may carry out this work.
  2. Notifiable non-licensed work (NNLW) — lower-risk tasks that must still be notified to the relevant enforcing authority, with medical surveillance required and records kept for 40 years.
  3. Non-licensed work — the lowest risk category, though still subject to strict controls and safe working practices.

If you are arranging asbestos removal for your property, always verify that the contractor holds a current HSE asbestos licence. Licences are publicly verifiable, and using an unlicensed contractor for licensable work exposes both you and the contractor to serious legal liability.

The Role of Asbestos Surveys Before Any Work Begins

Before any refurbishment, demolition, or removal work begins — and as part of ongoing management — a professional asbestos survey is essential. The type of survey required depends on the circumstances.

Management Surveys

A management survey is the standard survey used to locate ACMs that could be disturbed during normal occupation and routine maintenance. It involves a thorough visual inspection and sampling of suspected materials, with the results feeding directly into your asbestos register and management plan.

If you are responsible for a commercial or public building and you don’t yet have a current management survey in place, commissioning one is the single most important step you can take right now. Without it, you cannot fulfil your legal duty to manage.

Refurbishment and Demolition Surveys

Before any structural work, a demolition survey is required. This is a more intrusive survey designed to locate all ACMs in the areas to be worked on — including those that are hidden or inaccessible in voids, beneath floors, and behind wall linings.

Work must not begin until this survey is complete and the findings have been acted upon. Surveys must be carried out by competent, trained surveyors, and analysis of samples must be performed by a UKAS-accredited laboratory. This is not an area where cutting corners is acceptable or legal.

How the Management and Removal of Asbestos Works in Practice

Safe asbestos removal follows a structured, tightly regulated process. Here is what that looks like on the ground.

Risk Assessment and Planning

Before any removal work begins, a detailed risk assessment must be completed. This identifies the type and condition of ACMs, the scope of work, potential exposure risks, and the control measures needed. A written plan of work is then produced, setting out exactly how the job will be carried out safely.

The control limit for asbestos fibres under UK regulations is 0.1 fibres per cubic centimetre of air, averaged over a four-hour period. All work must be planned and executed to keep exposure well below this limit — ideally as close to zero as practically achievable.

Establishing a Controlled Work Area

For licensed asbestos removal, the work area is fully enclosed and sealed before work begins. This typically involves:

  • Erecting a polythene enclosure around the work area
  • Sealing all openings including windows, doors, and ventilation systems
  • Setting up an airlock and decontamination unit for workers to enter and exit safely
  • Running negative pressure air filtration units fitted with HEPA filters to maintain negative air pressure inside the enclosure

Negative air pressure means any air leakage flows inward rather than outward, preventing fibres from escaping into the wider building or environment. It is one of the most critical safeguards in the entire process.

The Removal Process Itself

Workers inside the enclosure wear full personal protective equipment (PPE), including disposable coveralls, gloves, and appropriate respiratory protective equipment (RPE). For licensed work, this means powered air-purifying respirators or similar high-protection-factor equipment.

Wet removal techniques are used wherever possible. Wetting the material before and during removal suppresses fibre release significantly. Power tools are avoided or strictly controlled, as they generate far more dust than manual methods.

All asbestos waste is double-bagged in heavy-duty polythene sheeting of at least 1000 gauge, clearly labelled as asbestos waste, and transported to a licensed waste disposal facility. Asbestos waste cannot be disposed of at standard landfill sites — it must go to a site specifically licensed to accept hazardous waste. Our dedicated asbestos removal service page explains exactly what this involves for your property type.

Decontamination Procedures

Workers must decontaminate before leaving the work area. This involves a staged process through the decontamination unit — removing contaminated coveralls, showering, and changing into clean clothing. Contaminated PPE is treated as asbestos waste.

After removal is complete, the work area is thoroughly cleaned using HEPA-filtered vacuum equipment. All surfaces — including heating and ventilation systems — are vacuumed and wiped down before the enclosure is removed.

Clearance Inspection and Air Testing

The final stage before the area is handed back for normal use is a four-stage clearance procedure. This is carried out by an independent UKAS-accredited analyst — not the removal contractor — and includes:

  1. A thorough visual inspection of the work area to confirm no visible debris remains
  2. A second visual inspection after any additional cleaning
  3. Air sampling using aggressive air monitoring techniques
  4. Analysis of air samples to confirm fibre levels are below the clearance indicator of 0.01 fibres per cubic centimetre

Only once the clearance certificate has been issued can the area be returned to normal use. This independent sign-off is a critical safeguard — it ensures the removal contractor cannot simply declare their own work satisfactory.

Managing Asbestos in Place: When Removal Isn’t the Answer

Removal is not always the right approach. In many cases, ACMs that are in good condition and unlikely to be disturbed are best left in place and managed. Disturbing asbestos unnecessarily can create risks that didn’t previously exist.

Where ACMs are retained, the dutyholder must:

  • Record their location and condition in the asbestos register
  • Ensure all contractors and maintenance workers are made aware of their presence before starting any work
  • Monitor the condition of ACMs regularly and update the register accordingly
  • Arrange removal or encapsulation where the condition deteriorates or planned work would disturb the material

Encapsulation — applying a sealant to the surface of ACMs to bind fibres and prevent release — is another option in some circumstances. However, encapsulation is not a permanent solution and requires ongoing monitoring and periodic re-inspection. It should never be used as a way to avoid dealing with seriously deteriorated material.

Training, Medical Surveillance, and Ongoing Prevention

The regulatory framework around asbestos isn’t just about the removal process itself. It also covers the people doing the work and those who may encounter asbestos in the course of their jobs.

Asbestos Awareness Training

Anyone whose work could foreseeably disturb asbestos — tradespeople, maintenance workers, construction workers — must receive asbestos awareness training. This is a legal requirement under the Control of Asbestos Regulations.

The training covers what asbestos is, where it is likely to be found, the health risks it poses, and what to do if ACMs are encountered unexpectedly. It is not optional, and it is not a one-off event.

Medical Surveillance

Workers carrying out notifiable non-licensed work or licensed asbestos work must be placed under medical surveillance by an HSE-appointed doctor. Health records for these workers must be retained for 40 years — reflecting the long latency period of asbestos-related diseases.

This isn’t bureaucracy for its own sake. It’s a mechanism for detecting early signs of disease and ensuring accountability across the industry over the long term.

Annual Refresher Training

Annual refresher training is mandatory for workers carrying out both licensable and non-licensable asbestos work. Procedures, regulations, and best practice evolve, and workers need to stay current.

Building managers should ensure that any contractor they engage can demonstrate up-to-date training records before work begins. Asking for this documentation is not unreasonable — it is due diligence.

What to Do If You Suspect Asbestos in Your Building

If you manage or own a building constructed before 2000 and you’re unsure whether asbestos is present, the starting point is always a professional survey. Do not attempt to sample or disturb suspected ACMs yourself — this is both dangerous and potentially unlawful.

Here’s a straightforward action plan:

  1. Commission a management survey — this establishes what is present, where it is, and what condition it’s in.
  2. Create or update your asbestos register — based on the survey findings, document all ACMs and their risk ratings.
  3. Develop an asbestos management plan — set out how each ACM will be managed, monitored, and reviewed.
  4. Communicate with contractors and maintenance staff — anyone who may work in the building must be informed of ACM locations before they start.
  5. Arrange removal or encapsulation where required — particularly before any refurbishment or demolition work, and whenever ACMs are deteriorating or at risk of disturbance.
  6. Review regularly — your asbestos management plan is a living document, not a one-time exercise.

Frequently Asked Questions

What is the difference between asbestos management and asbestos removal?

Asbestos management means keeping asbestos-containing materials (ACMs) safely in place through regular monitoring, maintaining an asbestos register, and ensuring anyone working in the building is aware of their location. Asbestos removal means physically extracting ACMs from the building using licensed contractors and controlled procedures. Management is often the preferred approach for ACMs in good condition; removal becomes necessary when materials are deteriorating, or when refurbishment or demolition work is planned.

Do I legally need an asbestos survey before refurbishment work?

Yes. Under the Control of Asbestos Regulations and HSE guidance in HSG264, a refurbishment and demolition survey is a legal requirement before any work that could disturb the fabric of a building built before 2000. Starting work without one puts workers at risk and exposes the dutyholder to serious legal liability, including prosecution.

Can I leave asbestos in place rather than removing it?

In many cases, yes — provided the ACMs are in good condition, are not likely to be disturbed, and are properly managed. The Control of Asbestos Regulations do not require removal as a default. However, ACMs must be recorded in your asbestos register, monitored regularly, and removed if their condition deteriorates or if planned work would disturb them. Removal is always required before demolition.

How do I know if an asbestos removal contractor is licensed?

HSE asbestos removal licences are publicly verifiable. You can check whether a contractor holds a current licence directly through the HSE website. For any licensable asbestos work — including removal of asbestos insulating board, sprayed coatings, and pipe lagging — only a contractor with a valid HSE licence may legally carry out the work. Always ask to see evidence of a current licence before appointing a contractor.

How long does asbestos removal take?

The duration depends on the quantity and type of ACMs, the complexity of the work area, and the access arrangements. A small removal job in a straightforward location might take one to two days; a large-scale project in a complex building could take several weeks. The four-stage clearance procedure at the end — including independent air testing — adds time but cannot be skipped. Your contractor should provide a detailed programme as part of their plan of work.
