What Every Homeowner Must Know About Dealing with Asbestos During Renovations
Picking up a sledgehammer to knock through a wall feels satisfying — until you realise the house was built before the mid-1980s and that dusty material crumbling around you might be asbestos. Dealing with asbestos during home renovations is one of the most serious hazards a homeowner can face, and getting it wrong doesn’t just mean a fine. It can mean decades of irreversible lung damage.
This post walks you through exactly what to do, what to avoid, and how to keep your family safe from one of the UK’s most persistent building hazards.
Where Asbestos Hides in Older Properties
Asbestos was used extensively in UK construction right up until its full ban in 1999. If your home was built or significantly refurbished before that date, there’s a real chance it contains asbestos-containing materials (ACMs) somewhere.
The tricky part is that asbestos doesn’t announce itself. It blends into ordinary building materials, and you simply cannot identify it by looking at it.
Common Locations in Domestic Properties
- Textured coatings — Artex and similar ceiling finishes were frequently made with asbestos fibres
- Floor tiles — Vinyl and thermoplastic floor tiles, particularly in kitchens and bathrooms
- Pipe lagging and boiler insulation — Especially in older heating systems
- Roof materials — Corrugated asbestos cement sheets on garages, outbuildings, and flat roofs
- Soffit boards and fascias — Often made from asbestos cement in properties from the 1960s to 1980s
- Partition walls and ceiling tiles — Particularly in properties that were converted or extended
- Insulation board — Around fireplaces, in airing cupboards, and behind storage heaters
The risk isn’t just in the obvious places. Renovators have disturbed asbestos in areas they never expected, which is exactly why a professional survey before any significant work is not optional — it’s essential.
How to Confirm Whether a Material Contains Asbestos
Suspecting asbestos and confirming it are two very different things. Never assume a material is safe just because it looks undamaged or because the previous owner said it was fine.
The only reliable way to confirm the presence of asbestos is through laboratory analysis of a physical sample. There are two main testing methods used in the UK:
- Polarised Light Microscopy (PLM) — The standard method for identifying asbestos type and concentration. Generally the more cost-effective option per sample.
- Transmission Electron Microscopy (TEM) — A more detailed analytical method used when greater precision is required, typically at a higher cost.
Home testing options are available — you can purchase an asbestos testing kit if you want an initial indication — but they carry significant limitations. They rely on the homeowner taking samples safely, which itself requires proper PPE and technique, and the results are only as good as the lab processing them.
For anything beyond a preliminary check, professional asbestos testing conducted by a UKAS-accredited surveyor is the correct approach. A qualified surveyor will inspect the property, take samples under controlled conditions, and provide a written report detailing the location, condition, and risk level of any ACMs found.
If you’re based in the capital, an asbestos survey London from a qualified team will give you that documented baseline before any renovation work begins.
The Dos of Dealing with Asbestos Safely
If asbestos is confirmed or strongly suspected in your property, there are clear steps you must take to protect yourself, your family, and anyone else on site.
Do Get a Professional Survey Before You Start Work
Before any demolition, drilling, or stripping work, commission a management or refurbishment survey depending on the scope of your project. A refurbishment survey is specifically designed to locate ACMs in areas that will be disturbed during building work.
This isn’t bureaucracy for its own sake. Disturbing hidden asbestos without knowing it’s there is how people end up with serious, life-limiting conditions that may not appear for 20 to 40 years after exposure.
If the scope of your project involves taking down significant structures, a demolition survey is the appropriate route. This is a more intrusive investigation designed to locate all ACMs throughout the entire structure before any demolition work commences.
Do Hire a Licensed Asbestos Removal Contractor
For certain categories of asbestos — particularly those classified as high-risk, such as sprayed coatings, asbestos insulating board, and pipe lagging — removal must be carried out by a contractor licensed by the Health and Safety Executive (HSE). This is a legal requirement under the Control of Asbestos Regulations, not a recommendation.
Even for lower-risk materials, using a trained and competent contractor is strongly advisable. Licensed contractors are assessed against strict competency standards, carry appropriate insurance, and know how to handle, contain, and dispose of ACMs without creating a wider hazard.
Professional asbestos removal contractors will also notify the HSE prior to licensed work beginning, manage the enclosure and decontamination process, and arrange for compliant disposal — all of which are your legal responsibilities as the property owner if you attempt to manage it yourself.
Do Seal Off the Work Area Properly
If any work involving ACMs is being carried out, the area must be properly enclosed. This means sealing internal doorways and ventilation openings with heavy-duty polythene sheeting, creating an air-controlled environment that prevents fibres from migrating to other parts of the building.
Negative pressure units are used by professional contractors to ensure that any airborne fibres are drawn inward rather than pushed outward into the rest of the property. This is standard practice for licensed work and reflects the level of control required when dealing with asbestos.
Do Wear the Correct Personal Protective Equipment
If you’re in a situation where you must handle a very minor, low-risk task involving suspected ACMs — and you’ve taken professional advice that this is appropriate — PPE is non-negotiable. The minimum requirement includes:
- A disposable Type 5 Category 3 coverall (not a standard decorator’s suit)
- A correctly fitted FFP3 respirator — not a standard dust mask
- Disposable gloves
- Overshoes or boot covers
All PPE must be disposed of as asbestos waste after use. You should shower thoroughly before leaving the work area, and any clothing worn underneath should be bagged and washed separately.
Do Use Non-Powered Hand Tools for Any Minor Tasks
If minor work around intact, low-risk ACMs is unavoidable, use only non-powered hand tools. Power tools — drills, angle grinders, sanders, and circular saws — generate significant quantities of fine dust, dramatically increasing the risk of fibre release.
A hand saw or manual screwdriver produces far less disturbance and keeps fibre levels considerably lower. Even then, any such work should only proceed after professional advice confirms it is appropriate.
The Don’ts of Dealing with Asbestos
Knowing what not to do is just as important as knowing the correct procedure. These aren’t suggestions — they’re the difference between a manageable situation and a serious health incident.
Don’t Cut, Drill, Sand, or Saw Suspected ACMs
This is the most critical rule. Cutting or abrading asbestos-containing materials releases microscopic fibres into the air. These fibres are invisible to the naked eye, have no smell, and can remain suspended in the air for hours.
Once inhaled, they cannot be expelled by the body and accumulate in lung tissue over time. Diseases linked to asbestos exposure — including mesothelioma, asbestosis, and asbestos-related lung cancer — are irreversible and frequently fatal. There is no safe level of exposure to asbestos fibres, and no cure for the diseases they cause.
Don’t Dispose of Asbestos Waste in Standard Bins
Asbestos waste is classified as hazardous waste under UK law. It cannot go in your wheelie bin, a standard skip, or a general waste facility. Doing so is a criminal offence that can result in substantial fines.
All asbestos waste must be double-wrapped in heavy-duty polythene sheeting of at least 0.2mm thickness, clearly labelled as ‘ASBESTOS WASTE’, and transported to a licensed hazardous waste disposal site. Licensed contractors manage this as part of their service, which is another strong reason to use professionals rather than attempting removal yourself.
Don’t Work with Asbestos in Windy Conditions or Without Containment
Even outdoors, wind can carry asbestos fibres significant distances from the work area. If you’re working on external materials such as asbestos cement roof sheets or soffits, check weather conditions and postpone work if wind speeds are significant.
Neighbours should be informed before any asbestos work begins so they can close windows and doors. This is standard practice and reflects the duty of care you have to those around you.
Don’t Ignore Warning Signs of Potential Exposure
If you believe you may have disturbed asbestos — particularly if you’ve been working in an older property without a prior survey — don’t wait to see what happens. Seek medical advice and inform your GP that you may have been exposed to asbestos fibres.
Symptoms such as persistent breathlessness, a cough that won’t resolve, or chest tightness following work in older buildings should always be investigated. The latency period for asbestos-related disease can be 20 to 40 years, but early documentation of potential exposure is important for any future medical assessment.
Understanding the Highest-Risk Renovation Tasks
Not all renovation work carries the same level of asbestos risk. The tasks most likely to disturb ACMs and release fibres include:
- Removing or sanding textured ceiling coatings — Artex applied before the late 1980s frequently contained chrysotile asbestos
- Lifting old vinyl or thermoplastic floor tiles — Both the tiles and the adhesive beneath can contain asbestos
- Drilling into walls or ceilings — Particularly in properties with asbestos insulating board or plasterboard containing ACMs
- Removing pipe lagging or boiler insulation — Often amosite or crocidolite, both highly hazardous
- Demolishing or altering partition walls — Especially in 1960s and 1970s commercial conversions and domestic extensions
If any of these tasks are part of your renovation plan, a refurbishment or demolition survey must be completed before work starts. This applies whether you’re a homeowner managing a DIY project or a contractor working on someone else’s property.
Safe Asbestos Disposal: What the Law Requires
Disposal of asbestos waste is tightly regulated in the UK. Getting this wrong exposes you to criminal liability — so it’s worth understanding exactly what compliant disposal involves.
Packaging
All ACMs must be wrapped in two layers of heavy-duty polythene sheeting, with a minimum thickness of 0.2mm per layer. Smaller fragments and debris should be double-bagged.
Materials should be kept damp during wrapping to suppress fibre release, and all packages must be sealed securely with tape.
Labelling
Every package must be clearly labelled on all visible sides with the words ‘ASBESTOS WASTE’. This is a legal requirement, not a courtesy. Waste carriers and disposal site staff need to identify the material immediately to handle it safely.
Transport and Disposal
Asbestos waste must be transported by a registered waste carrier and taken to a licensed hazardous waste disposal facility. Your local council can provide information on approved sites in your area.
Licensed removal contractors manage this entire process as part of their service, which removes the legal burden from the property owner and ensures full compliance with the Control of Asbestos Regulations and associated waste legislation.
When to Encapsulate Rather Than Remove
Removal isn’t always the right answer. In some circumstances, encapsulation — sealing ACMs in place with a specialist coating or barrier — is a safer and more cost-effective approach than disturbing the material through removal.
Encapsulation is typically appropriate when the ACM is in good condition, is not in an area that will be regularly disturbed, and does not need to be removed for structural or renovation reasons. A professional survey will assess the condition of any ACMs and recommend whether encapsulation or removal is the more appropriate course of action.
However, encapsulation is not a permanent solution. The material still needs to be managed, monitored, and recorded as part of an asbestos management plan. If the property is later sold, renovated, or demolished, the ACMs will need to be addressed at that point.
Asbestos Rules for Contractors and Tradespeople
If you’re a builder, plumber, electrician, or other tradesperson working in domestic properties, the legal position is clear. Under the Control of Asbestos Regulations, anyone who may disturb asbestos during their work must receive adequate information, instruction, and training before doing so.
This is known as the duty to manage, and it extends to anyone working on non-domestic premises. For domestic properties, the duty falls primarily on the homeowner — but tradespeople still have a responsibility not to proceed with work if they suspect ACMs may be present and no survey has been carried out.
If you’re working in Manchester or Birmingham and need a rapid survey before a job can proceed, an asbestos survey Manchester or an asbestos survey Birmingham can be arranged at short notice through Supernova’s nationwide network of accredited surveyors.
The Role of Professional Asbestos Surveys in Renovation Planning
A professional asbestos survey isn’t just a box-ticking exercise — it’s a practical tool that tells you exactly what you’re dealing with before any work begins. The survey report will identify the location, type, condition, and risk rating of every ACM found, giving you and your contractors the information needed to plan the work safely.
The HSE’s guidance document HSG264 sets out the standards for asbestos surveying in the UK and defines the different survey types. A management survey is appropriate for routine occupation and maintenance. A refurbishment or demolition survey is required before any intrusive work that could disturb the fabric of the building.
If you’re unsure which type of survey you need, a conversation with a qualified surveyor before you commit to anything is always the right starting point. The cost of a survey is minimal compared to the cost — financial and personal — of getting it wrong.

Frequently Asked Questions
Can I remove asbestos myself from my own home?
For certain lower-risk, non-licensed materials — such as small amounts of asbestos cement — the law does not prohibit a homeowner from carrying out removal themselves. However, this is strongly discouraged. Without professional training, the correct PPE, proper containment, and compliant disposal arrangements, the risk of exposure is significant. For any high-risk materials such as sprayed coatings, asbestos insulating board, or pipe lagging, removal must legally be carried out by an HSE-licensed contractor.
How do I know if my Artex ceiling contains asbestos?
You cannot tell by looking at it. Artex and similar textured coatings applied before the late 1980s frequently contained chrysotile (white) asbestos. The only way to confirm whether your ceiling coating contains asbestos is to have a sample analysed by an accredited laboratory. You can use a testing kit for an initial indication, but a professional survey is the recommended approach before any sanding, scraping, or ceiling removal work takes place.
What happens if I accidentally disturb asbestos during renovation work?
Stop work immediately and leave the area. Do not attempt to clean up dust or debris with a household vacuum cleaner, as this will spread fibres further. Seal the area if possible and contact a licensed asbestos contractor to assess the situation and carry out a professional clean-up. Inform your GP that you may have been exposed to asbestos fibres, and keep a record of the date and circumstances of the potential exposure for future medical reference.
Is asbestos always dangerous, or only when disturbed?
Asbestos-containing materials that are in good condition and are not being disturbed present a much lower risk than damaged or friable ACMs. The danger arises when fibres are released into the air — typically through cutting, drilling, sanding, or physical deterioration of the material. This is why the standard advice for intact, low-risk ACMs in good condition is often to leave them in place and monitor them, rather than attempting removal and risking fibre release in the process.
Do I need an asbestos survey before selling my home?
There is no legal requirement to commission an asbestos survey before selling a residential property. However, if you are aware that ACMs are present, you have a legal obligation to disclose this information to potential buyers. Many buyers and their solicitors are now requesting asbestos surveys as part of the conveyancing process, particularly for pre-2000 properties. Having a current survey report available can speed up the sale and prevent last-minute complications.
