Do I need an asbestos survey before building work?

By Ajay Singh. Published 30 October 2026.

If you own and live in the home, we haven't found anything from HSE that says you must commission one yourself. But the firm doing the work has to deal with asbestos before it starts, so on a pre-2000 home, expect the question to come up. Getting an answer early is usually cheaper than getting it halfway through a job.

This is general information, not legal advice. We don't survey or remove asbestos. We pass enquiries to one independent firm, and we don't vet anyone.

Who's expected to do what

The firm doing the work. HSE (1 March 2021) tells anyone who employs people whose work might involve asbestos that they must find out if it's in a building before work starts. That includes looking for an existing survey, checking it suits the job, and writing a plan of work. Regulation 5 of the Control of Asbestos Regulations 2012 gives an employer two ways to meet this: assess what's present, or if in doubt, assume it's there and follow the regulations on that basis.

You, as the owner. HSE's FAQs (4 September 2025) say owner-occupiers aren't legally responsible for asbestos risks to contractors, because they aren't doing any work themselves. It does ask you to tell builders about any asbestos you know of before they start. MyJobQuote (9 September 2026) puts it plainly, saying no law requires a homeowner to have one, though that's a price guide, not a legal source.

Who books it. HSE doesn't say who should in a private house. In practice, it's you or the builder. Our view is that it's worth settling early, and getting it in writing. If you book it, you've got a report to give every firm pricing the job, which is what HSE's survey guide, HSG264 (second edition, 2012), recommends clients do at paragraph 52. If the builder books it, ask for a copy.

A builder may well ask for one before committing to a price. A survey is often simpler than assuming asbestos is everywhere, since that means full precautions on the work. HSE makes this point to people responsible for non-domestic buildings, and we think the same logic applies here. HSE's wording about the firm's side can be stronger, too. A press release on a large-scale case (9 March 2026) says employers must commission a refurbishment and demolition survey before work likely to disturb the fabric of a pre-2000 building.

Which homes and jobs it most applies to

Homes. HSE says asbestos may be in any home built or refurbished before 2000, and that buildings put up after 2000 are unlikely to have it. HSG264 says it was used extensively in homes from 1930 to 1980. So the 1930s semi and the 1970s bungalow are obvious candidates. So is an older house with a 1980s garage or kitchen extension, as refurbishment and later additions count too.

Jobs. It's about whether the work breaks into the building. HSG264 (paragraph 67) says a refurbishment and demolition survey is required for work that disturbs the fabric, and it's written mainly for non-domestic buildings and organisations that manage housing. On a house, these are the ones to think about:

• A loft conversion. The ceiling below gets cut for the stair, and the roof and any old water tank may be involved.
• A garage conversion. The roof, the soffits and old floor finishes are the usual concerns.
• An extension. Walls get broken through, and work meets the eaves and soffits.
• A garden room. A freestanding new building is a much lower concern, unless an old shed or garage is coming down first. That's our reading, so ask if that applies.

Our asbestos surveys page lists where it tends to be found, with sources.

What a refurbishment survey involves

This one's meant to find what's hidden, not just what's on show. HSG264 (paragraphs 51 and 53) calls it disruptive and fully intrusive. The surveyor may lift carpets and tiles, break through walls, ceilings and cladding, and open up floors. Asbestos can sit inside the structure, where a walk-through wouldn't show it, so that's why it goes so far.

The area has to be empty while it's done, with controls to stop debris spreading, and shown fit to go back into before you do. On a small job, the guide says this can be limited to one room or part of it. It should only cover where the work will happen, so a survey for a loft shouldn't mean opening up your kitchen.

Don't try a smaller version yourself. HSE and NHS inform both warn against trying to remove suspect material, and HSE says samples should be taken by a suitably trained person. In good condition and left alone, HSE says the risk is extremely low, so there's no rush to go poking at anything.

When to do it

Before quotes are final. HSG264 (paragraph 68) says that for house improvement work, the survey should go into the planning phase as far as possible, to avoid delays. Paragraph 52 says the report should go to the designers and contractors bidding for the work.

A sensible order, in our view, looks like this:

1. Get a rough idea of the design, so you know which parts of the house will be touched. See is my loft suitable? if you're at that stage.
2. Ask whether you or the builder will arrange the survey.
3. Get it done, with the area cleared. Published UK prices and timings are on our survey page.
4. Give the report to every firm you're asking to price, so that removal is either in the quote or clearly priced as an extra.
5. Check the quote says who'll do any removal, and whether it's licensed work.

Otherwise, you can end up with a price that doesn't include it. MyJobQuote's loft conversion guide (21 October 2026) lists finding asbestos among the costs a typical quote may not cover. It's better to know early than to have the job stop while someone works out what to do.

If you let the property out, your position isn't the same as an owner-occupier's, and you shouldn't rely on this guide. HSG264 (paragraphs 10 to 12) goes through it, so take advice.
