Finding suspected asbestos during building, renovation or maintenance work can bring your project to a sudden halt. However, discovering a material that may contain asbestos does not necessarily mean there is an immediate danger.

Asbestos-containing materials that are in good condition and remain undisturbed generally present a much lower risk. The concern arises when asbestos-containing materials are damaged or disturbed, potentially releasing microscopic fibres into the air.

Taking the right steps immediately can help protect everyone involved and ensure your project can continue safely.

Stop, Isolate and Do Not Disturb

If you uncover suspected asbestos while carrying out work, your immediate priority should be to stop work and avoid any further disturbance.



1. Stop what you're doing and leave the area. Switch off equipment where it is safe to do so, step away from the affected area and prevent other people from entering.
2. Do not attempt to clean it up. Never sweep, vacuum, drill, sand or otherwise disturb suspected asbestos containing debris. A standard household vacuum cleaner is not suitable for cleaning asbestos contamination and could spread fibres further.
3. Restrict access to the area. Close the area off where practical and avoid doing anything that could further disturb the material or spread dust to other parts of the property.

If significant damage or dust has been created, seek professional advice before attempting to clean or re-enter the affected area to avoid a serious health risk.

Why You Cannot Confirm Asbestos by Eye

You cannot reliably identify asbestos simply by looking at it.

Asbestos-containing materials were extensively used in UK buildings before asbestos was completely banned in 1999. They may still be present in homes, commercial premises and public buildings constructed or refurbished before 2000.

Common locations and materials include:

• Textured coatings
• Garage and outbuilding roof sheets
• Asbestos insulating board (AIB)
• Pipe and boiler insulation
• Floor tiles
• Soffits and panels
• Ceiling tiles
• Fire-resistant boards and linings

Many asbestos-containing materials can look very similar to modern asbestos-free alternatives.

If you are unsure, do not disturb the material and arrange for appropriate professional advice or testing.

Asbestos Survey vs Sampling: Which Do You Need?

The right approach will depend on the property and what you intend to do.

If you have discovered one isolated suspect material, targeted sampling may sometimes be appropriate. A competent asbestos surveyor can take a controlled sample which is then analysed by an appropriately accredited laboratory to establish whether asbestos is present.

If you are responsible for a non-domestic property, planning significant refurbishment or carrying out demolition work, a more comprehensive asbestos survey may be required.

Different types of asbestos surveys are designed for different purposes, so it is important to obtain advice on the appropriate survey for your circumstances.

Your Options Once Asbestos Is Confirmed

Finding asbestos does not automatically mean it needs to be removed.

Depending on the type of material, its condition, location and your future plans for the property, options may include:

• Manage in place: If the asbestos-containing material is in good condition and unlikely to be disturbed, it may be appropriate to leave it in position and manage its condition.
• Asbestos Containment (Encapsulation): Certain asbestos-containing materials can be sealed or protected to help prevent damage and fibre release. This can be an effective alternative to removal in appropriate circumstances. It's a cost-effective choice for items like intact asbestos cement sheets or AIB panels.
• Asbestos removal: Where asbestos-containing material is damaged, deteriorating, poses an unacceptable risk or will be affected by planned works, professional removal may be the most appropriate solution.

Every situation is different, which is why a proper assessment is important before deciding how the asbestos should be managed.

The Risks of DIY Asbestos Removal

Asbestos should never be treated like ordinary building waste.

Exposure to airborne asbestos fibres can cause serious diseases including mesothelioma, asbestos-related lung cancer and asbestosis. These illnesses typically develop many years after exposure.

Certain higher-risk asbestos work can only legally be carried out by a contractor holding the appropriate HSE licence.

Even work involving lower-risk materials can require specific controls, training, protective equipment, handling procedures and compliant hazardous-waste disposal.

Attempting asbestos removal without the appropriate knowledge and controls can unnecessarily expose you and others and potentially contaminate other areas of the property.

What Happens During Professional Asbestos Removal?

The exact process depends on the type, condition, quantity and location of the asbestos-containing material.

Before work begins, the contractor will assess the risks and determine the appropriate method and controls.

Depending on the work involved, this may include:

• Establishing a controlled work area
• Using specialist protective and respiratory equipment
• Applying techniques designed to minimise fibre release
• Carefully removing asbestos-containing materials
• Correctly packaging and labelling asbestos waste
• Transporting waste in accordance with applicable hazardous-waste requirements
• Thoroughly cleaning the work area
• Carrying out appropriate inspection, testing or clearance procedures where required

Higher-risk licensed asbestos removal may require additional controls including specialist enclosures, negative-pressure equipment and formal clearance procedures.

Using an experienced asbestos removal contractor ensures the appropriate procedures are followed for the particular material and circumstances.

Frequently Asked Questions

What should I do if I accidentally damage suspected asbestos in my home?

Stop work immediately and avoid further disturbing the material. Keep other people away from the affected area and do not sweep or use a household vacuum cleaner to clean up debris or dust. Contact an asbestos professional for advice on the appropriate next steps.

Can I legally remove asbestos materials myself in the UK?

Not all asbestos work requires a licensed contractor, but certain higher-risk asbestos materials and types of work are subject to strict licensing requirements.

Even where work is classed as non-licensed, appropriate training, risk controls, personal protective equipment and waste-disposal procedures may still be required. For this reason, professional advice is strongly recommended before disturbing any known or suspected asbestos-containing material.

How do I know if my property contains asbestos insulating board or standard plasterboard?

You cannot reliably distinguish asbestos insulating board (AIB) from other building boards simply by looking at it.

AIB was historically used in locations including partition walls, ceiling tiles, fire protection and service risers. Appropriate sampling and laboratory analysis is required to confirm whether a suspect material contains asbestos.

What is the difference between encapsulation and asbestos removal?

Encapsulation involves treating or protecting an asbestos-containing material so that it remains safely in position and is less likely to release fibres.

Removal involves taking the higher risk material out of the property altogether and disposing of it through the appropriate hazardous-waste route.

Which option is most appropriate depends on the type and condition of the asbestos, where it is located and whether it is likely to be disturbed in the future.

Exposed to Asbestos: How Much Is Dangerous?

The risk of developing an asbestos-related disease generally increases with the amount of asbestos fibre inhaled and the frequency and duration of exposure.

Because asbestos exposure should always be minimised as far as reasonably practicable, suspected asbestos-containing materials should not be unnecessarily disturbed.

How is asbestos waste legally disposed of?

Asbestos waste must be appropriately contained, packaged and labelled before being transported and disposed of through an authorised hazardous-waste route.

The exact packaging method depends on the material and size of the waste. Smaller items may be appropriately bagged, while larger asbestos-containing materials may need to be securely wrapped.

Asbestos specialist contractors will ensure waste is handled, transported and disposed of in accordance with the applicable asbestos regulations.
