Asbestos Awareness for Builders: What You Need to Know Before You Start

Asbestos is still in millions of UK buildings. If you work on anything built before 2000, you need to know where it hides, what the law requires, and what to do if you find it.

Why asbestos still matters

Asbestos was banned in the UK in 1999, but that does not mean the problem is behind us. Far from it. Any building constructed or refurbished before the year 2000 may contain asbestos-containing materials (ACMs). That includes houses, schools, hospitals, offices, factories, and virtually every other type of building in the country.

Asbestos kills around 5,000 people every year in the UK — more than die in road traffic accidents. The vast majority of these deaths are from mesothelioma, a cancer of the lining of the lungs that is almost exclusively caused by asbestos exposure. Mesothelioma is incurable. Once diagnosed, life expectancy is typically 12 to 18 months.

The people dying today were exposed decades ago — asbestos diseases have a latency period of 15 to 60 years. That means the exposure happening now on construction sites, where builders unknowingly drill into, cut through, or rip out materials containing asbestos, will not show up as illness until the 2040s, 2050s, and beyond. This is not a historical problem. It is a current one, and builders are among the most at-risk groups.

The law is clear: if you are working on a pre-2000 building, you must consider asbestos before you start. Not halfway through. Not when someone gets worried. Before you pick up a tool.

Where asbestos is found in buildings

Asbestos was used in over 3,000 different building products. It was cheap, fireproof, and incredibly versatile, which is why it ended up everywhere. Here are the most common places builders encounter it:

  • Textured coatings (Artex). Stippled or swirled ceiling and wall coatings applied before the mid-1980s very commonly contain chrysotile (white) asbestos. Even coatings applied up to the mid-1990s may contain it.
  • Floor tiles and adhesives. Thermoplastic floor tiles, especially the 9-inch by 9-inch type, and the black bitumen adhesive used to stick them down frequently contain asbestos.
  • Cement roofing sheets and guttering. Corrugated cement roof sheets on garages, sheds, and industrial buildings are one of the most common ACMs in the UK. They typically contain 10 to 15 per cent chrysotile asbestos.
  • Pipe lagging and insulation. Thermal insulation on heating pipes, boilers, and ducts is one of the most dangerous forms of asbestos because it often contains amosite (brown) or crocidolite (blue) asbestos, which are the most hazardous types.
  • Soffits and fascias. Asbestos cement boards were widely used for soffits, fascias, and barge boards on residential and commercial buildings.
  • Fuse boxes and electrical panels. Asbestos insulating board was commonly used as a fire-resistant backing in electrical consumer units and distribution boards.
  • Toilet cisterns and flue pipes. Asbestos cement was used to manufacture toilet cisterns, water tanks, and flue pipes. These are easily overlooked during refurbishment work.
  • Behind plasterwork. Asbestos insulating board was often used as a fire break behind plasterwork, in partition walls, and around structural steelwork.
  • Window putty. Some window putties and sealants manufactured before 2000 contain asbestos. Removing old windows can release fibres if the putty is disturbed without precautions.

This is not an exhaustive list. Asbestos turns up in places you would never expect. The only safe assumption when working on a pre-2000 building is that ACMs may be present until a competent survey proves otherwise.

The duty to manage — Regulation 4

Regulation 4 of the Control of Asbestos Regulations 2012 places a duty to manage asbestos on the person responsible for maintaining or repairing non-domestic premises. This person is known as the duty holder and is usually the building owner, landlord, or managing agent.

The duty holder must take reasonable steps to find out whether asbestos-containing materials are present in the building, assess their condition, presume materials contain asbestos unless there is strong evidence they do not, prepare a written management plan, and provide information about the location and condition of ACMs to anyone who might disturb them — including builders.

For builders, the practical implication is this: before you start any refurbishment or demolition work on a pre-2000 building, ask the client for the asbestos survey. If they do not have one, they need to commission one. Do not start work without it. If the client tells you there is no asbestos, ask how they know. If the answer is “I just know” or “the last builder said it was fine,” that is not good enough. You need a proper survey carried out by a competent person.

The duty to manage applies to non-domestic premises and the common areas of domestic premises (such as shared hallways in blocks of flats). For purely domestic properties, there is no legal duty to manage, but as a builder, you still have a duty under the Health and Safety at Work Act to protect yourself and your workers. That means you should still check for asbestos before starting work on a house built before 2000.

Types of asbestos survey

There are two types of asbestos survey, and understanding the difference is essential for builders. Using the wrong type of survey for the work you are doing can leave you exposed — literally.

Management survey

The standard survey for buildings in normal use. It identifies ACMs that could be disturbed during normal occupation, routine maintenance, or minor works. The surveyor inspects accessible areas and takes samples, but does not cause significant damage to the building. Suitable for ongoing building management but not sufficient for refurbishment or demolition work.

Refurbishment / demolition survey

A fully intrusive survey required before any refurbishment or demolition work on a pre-2000 building. The surveyor accesses areas behind walls, above ceilings, beneath floors, and inside ducts. The area must be vacated before the survey because the surveyor will need to cause damage to reach hidden materials. This is the survey builders need.

If a client shows you a management survey and says “we have had a survey done,” check what type it is. A management survey does not cover hidden areas that your refurbishment work will expose. You need a refurbishment survey for the specific areas where you will be working.

What to do if you find suspected asbestos

Even with a survey, there is always a chance you will come across something unexpected. If you find a material you suspect might contain asbestos, follow these steps:

1.Stop work immediately

Do not continue with the task. Do not try to finish what you were doing. Stop straight away.

2.Do not disturb the material

Do not break it, drill it, sand it, scrape it, or attempt to remove it. The danger from asbestos comes when fibres are released into the air, so the priority is to avoid creating any more disturbance.

3.Keep people away from the area

Move everyone out of the immediate vicinity and prevent anyone from entering. If possible, close doors to contain any fibres that may have been released.

4.Report to the site manager or client

Inform the person in charge of the site immediately. They need to arrange for the material to be assessed by a competent person.

5.Do not attempt to remove it yourself

Unless you hold the appropriate licence and training, do not try to handle, bag, or dispose of the material. Unlicensed asbestos removal is a criminal offence for certain types of ACM.

6.Get it tested

Arrange for a sample to be taken by a competent surveyor and sent to a UKAS-accredited laboratory for analysis. Do not take the sample yourself unless you have been trained to do so safely.

Licensed vs non-licensed asbestos work

Not all asbestos work requires a licensed contractor, but knowing which category your work falls into is critical. Get it wrong and you face prosecution. UK law divides asbestos work into three categories:

Licensed work

Work with the most dangerous forms of asbestos: sprayed coatings, lagging on pipes and boilers, and asbestos insulating board (AIB) in poor condition. This work must be carried out by an HSE-licensed contractor. The HSE must be notified at least 14 days before work begins, and the contractor must hold a current asbestos removal licence.

Notifiable non-licensed work (NNLW)

Work with lower-risk ACMs where exposure is not sporadic and of low intensity. Examples include removing asbestos cement sheets, textured coatings containing asbestos, or asbestos-containing floor tiles. You do not need an HSE licence, but you must notify the HSE using form ASB5 before work starts, carry out a risk assessment, use appropriate controls including RPE and PPE, and maintain medical surveillance records.

Non-licensed work

Very short-duration, low-risk tasks where fibre release is minimal and sporadic. Examples include minor repairs to undamaged asbestos cement, or removing a single cement sheet in good condition using hand tools. Even for this category, you still need asbestos awareness training, a suitable risk assessment, and appropriate PPE.

If you are unsure which category applies, treat the work as licensed and bring in a specialist. The consequences of getting this wrong are severe — both for your health and your business.

How The Site Book handles asbestos

Asbestos is one of the most serious risks a builder can face, and it is easy to overlook when you are focused on getting the job done. The Site Book is designed to make sure it does not get missed.

When you create a project in The Site Book, it automatically flags pre-2000 buildings and prompts you to confirm whether an asbestos survey has been carried out. If the building was constructed or refurbished before 2000, the system will not let you overlook it — it builds asbestos considerations into your project documentation from the start.

Your RAMS will include asbestos-specific precautions where relevant, covering what to do if suspected ACMs are found, the requirement for a refurbishment survey, and the procedure for stopping work and reporting. This means your safety documentation already addresses one of the highest-risk hazards in construction, without you having to write it from scratch.

Frequently asked questions

Common questions builders ask about asbestos awareness and compliance.

Do I need asbestos awareness training?

Yes. Under Regulation 10 of the Control of Asbestos Regulations 2012, every employer must ensure that anyone who is liable to be exposed to asbestos during their work receives adequate information, instruction, and training. In practice, this means that every builder, tradesperson, and labourer who works on buildings built or refurbished before 2000 needs asbestos awareness training. This is not limited to people who work with asbestos directly — it covers anyone who might accidentally disturb it. The training must cover the properties of asbestos, its health effects, where it is likely to be found in buildings, how to avoid disturbing it, and what to do if you come across it. Asbestos awareness training is widely available online and typically takes half a day. Many CITB-affiliated training providers offer it, and it is often included as part of the CSCS Health, Safety and Environment test preparation. The training should be refreshed regularly — the HSE recommends annual refresher training as a minimum. If you employ anyone, you are legally responsible for making sure they have had this training before they start work on any pre-2000 building. Even if you are a sole trader, completing the training protects you and demonstrates to clients and the HSE that you take your legal obligations seriously.

Can I remove asbestos myself?

It depends on the type of asbestos and the type of work. There are three categories of asbestos work under UK law. Licensed work covers the most dangerous types — sprayed coatings, lagging on pipes and boilers, and asbestos insulating board in poor condition. This work must be carried out by a contractor licensed by the HSE, and it requires notification to the HSE at least 14 days before work starts. Notifiable non-licensed work (NNLW) covers some lower-risk tasks such as removing asbestos cement sheets, textured coatings, or certain floor tiles. You do not need an HSE licence for this work, but you must notify the HSE using ASB5, carry out a risk assessment, have appropriate training beyond basic awareness, use the correct PPE and RPE, and follow specific procedures for containment and waste disposal. Non-licensed work covers very short-duration, low-risk tasks where fibre release is minimal, such as removing a single asbestos cement sheet that is in good condition. Even for this category, you still need asbestos awareness training and must follow safe working practices. The critical point is that you cannot determine which category applies without knowing what type of asbestos you are dealing with and what condition it is in. That requires a survey by a competent person and, in many cases, laboratory analysis. Never assume a material is safe to remove yourself. If in doubt, treat it as licensed work and call a specialist.

How do I know if a material contains asbestos?

You cannot tell whether a material contains asbestos just by looking at it. Asbestos fibres are microscopic, and asbestos was mixed into hundreds of different building products between the 1950s and 1999. Textured ceiling coatings can look identical whether they contain asbestos or not. The same is true for floor tiles, cement sheets, insulation boards, and virtually every other material that might contain asbestos. The only reliable way to confirm whether a material contains asbestos is to have a sample analysed by a UKAS-accredited laboratory. A competent surveyor will take samples during an asbestos survey and send them for analysis. The laboratory uses polarised light microscopy or other techniques to identify the presence and type of asbestos fibres. Results typically come back within a few days. As a general rule of thumb, if a building was built or significantly refurbished before the year 2000, you should assume that asbestos-containing materials may be present until a survey proves otherwise. Do not rely on the age of the building alone — asbestos materials were sometimes installed during later refurbishment work even in relatively modern buildings. The cost of having a sample tested is typically between twenty and fifty pounds per sample, which is a small price compared to the consequences of disturbing asbestos unknowingly.

What is the difference between a management survey and a refurbishment survey?

A management survey is the standard survey that should be carried out on any building likely to contain asbestos-containing materials. Its purpose is to locate ACMs that could be disturbed during normal occupation, routine maintenance, or minor works. The surveyor will inspect accessible areas and take samples where they suspect ACMs may be present, but they will not rip open walls, lift floors, or cause significant damage to the building fabric. A management survey tells you what is there and what condition it is in, so the building owner can create a management plan. A refurbishment or demolition survey, by contrast, is fully intrusive. The surveyor needs access to every part of the building that will be affected by the planned work, including behind walls, above ceilings, beneath floors, and inside ducts. This survey is required before any refurbishment or demolition work begins on a building that was built or refurbished before 2000. It must be carried out in the specific area where the work will take place, and the area should be vacated and made safe before the survey begins because the surveyor will need to cause damage to access hidden areas. The key distinction is purpose and scope. A management survey is for ongoing building management. A refurbishment survey is for planned construction work. If you are a builder about to start a refurbishment project on a pre-2000 building, you need a refurbishment survey for the areas you will be working in — a management survey alone is not sufficient.

What happens if I disturb asbestos accidentally?

If you accidentally disturb material that you suspect contains asbestos, stop work immediately. Do not try to clean it up, sweep it, or continue with the task. Move yourself and anyone else away from the area and prevent other people from entering. If the material has been broken, drilled, sanded, or otherwise damaged, fibres may have been released into the air. Keep the area sealed off and do not allow anyone to re-enter without appropriate protection. Report the incident to the site manager, the client, and your employer if applicable. Under RIDDOR, the accidental release of asbestos is a dangerous occurrence that must be reported to the HSE. Contact a licensed asbestos removal contractor to assess the situation and carry out any necessary decontamination. The area may need to be enclosed, air monitoring may be required, and any contaminated materials, clothing, or equipment will need to be disposed of as asbestos waste. Do not try to handle any of this yourself unless you hold the appropriate licence and training. Anyone who was in the area when the disturbance occurred should make a note of the date, duration of potential exposure, and the type of work they were doing. This information should be kept on their medical records. A single brief exposure to asbestos does not mean you will develop an asbestos-related disease, but it is important to have the incident properly recorded. The Health and Safety Executive takes accidental asbestos disturbance seriously, and failing to report it or attempting to cover it up can result in prosecution.
