There is no comprehensive count of UK homes containing asbestos. Official guidance identifies pre-2000 buildings as the main concern, while selected surveys and historical estimates describe different parts of the building stock. This page separates those measures so that a percentage from surveyed social housing is not mistaken for a national household prevalence rate.
It's written for anyone who needs citable numbers — journalists, students, landlords, renovators, and the dutyholders who manage buildings — with the data period stated alongside every figure.
Key facts and figures
- 86% of surveyed homes — 80,731 of 94,116 domestic properties — contained asbestos in the ATaC/NORAC October 2021–March 2022 sample, overwhelmingly social housing.
- 94,116 domestic properties formed 73% of the ATaC/NORAC sample; this was not a random survey of all UK homes.
- ~1.5 million buildings was a historical estimate cited by ResPublica in 2019, not a current official count of homes.
- ~310,000 non-domestic premises was HSE’s provisional best estimate reported to Parliament in 2022, within a range of 210,000–410,000.
- 71% of asbestos items logged across 128,000+ UK building surveys showed some damage (ATaC/NORAC, November 2022).
- Pre-2000 buildings may contain asbestos. Building age is a warning to investigate, not proof of its presence.
- 389,700 asbestos items were identified in the domestic properties in the ATaC/NORAC 2021/22 sample.
- 2,146 mesothelioma deaths were recorded provisionally in Great Britain in 2024; HSE published these figures in July 2026.
Reviewed on 15 October 2026. Building estimates and survey findings retain their original dates. They are not a 2026 census. The latest HSE mortality figures cover 2024 and primarily reflect exposure decades earlier.
How many UK homes contain asbestos?
No official national household percentage is established by the UKHSA guidance cited here. The ATaC/NORAC report found asbestos in 80,731 of 94,116 domestic properties surveyed between October 2021 and March 2022, about 86%. However, 99.5% of its domestic sample was housing controlled by registered social landlords. That selected sample cannot tell us what proportion of all privately owned, privately rented or UK homes contains asbestos.
HSE advises that asbestos may be present in buildings constructed before 2000. Construction and refurbishment dates help identify where to investigate, but do not confirm whether a particular material contains asbestos. Where relevant, a competent survey and analysis by a suitably accredited laboratory establish the material’s identity; appropriate precautions are needed where its status remains uncertain.
The main prohibition on chrysotile took effect in Great Britain on 24 November 1999 and in Northern Ireland on 2 May 2000, with limited exceptions at the time. Older blue and brown asbestos had been prohibited earlier. Our ban timeline explains the jurisdictional differences. The practical pre-2000 screening rule is not a guarantee that a later building is free of every legacy material.
How many buildings contain asbestos in the UK?
There is no reliable single range covering all UK buildings. Estimates of non-domestic premises, campaign estimates for wider building stock and findings from selected homes have different denominators. They should be shown separately, with their dates and limitations.
| Measure | What it counts | Source and date |
|---|---|---|
| About 310,000; range 210,000–410,000 | Provisional estimate of GB non-domestic premises containing asbestos | HSE evidence to Parliament, 2022 |
| About 1.5 million buildings | Historical broader estimate cited in a campaign report; not a domestic census | ResPublica, 2019 |
| 94,116 properties | Domestic sites selected for surveys, overwhelmingly social housing | ATaC/NORAC, October 2021–March 2022 |
| 80,731 (86%) | Surveyed domestic properties containing asbestos | ATaC/NORAC, same selected sample |
| 389,700 items | Asbestos-containing items in the domestic sample | ATaC/NORAC, same survey period |
In 2022 HSE clarified its non-domestic estimate to Parliament as a provisional best estimate of 310,000, within a range of 210,000–410,000. ResPublica’s 2019 report cited around 1.5 million buildings and six million tonnes of asbestos; its references include older estimates and historic imports. Those figures do not establish a current domestic prevalence rate or a measured tonnage still in buildings.
Why do the estimates differ so much?
The sources differ in scope, selection and method. A national estimate of workplaces cannot be compared directly with a percentage from surveyed social housing or with a historical campaign estimate.
- Scope. HSE’s 2022 estimate concerns non-domestic premises; the ATaC/NORAC domestic subset largely concerns social housing.
- Method. Estimates and selected commercial surveys are different forms of evidence. Neither is a complete census of UK homes.
- No register. Because the UK has no national asbestos register (covered below), there is no mechanism for turning the thousands of individual building surveys carried out every year into one authoritative national count.
For a citation about homes, use the ATaC/NORAC result with its date and social-housing limitation. For the 2022 non-domestic estimate, use HSE’s stated range and describe it as provisional. Neither source establishes that half of all UK households contains asbestos.
Where is asbestos found in homes?
Any home built or refurbished before 2000 can contain asbestos, and in a typical pre-1985 property it can appear in almost every room. The most common locations are:
- Roofs and exteriors — corrugated asbestos cement on garages and outbuildings, roof tiles, soffits, fascias, gutters and downpipes
- Ceilings — older textured coatings, including some products sold under the Artex name, and asbestos insulating board (AIB) ceiling tiles. Do not use appearance or a mid-1980s cut-off to rule asbestos out.
- Walls and panels — AIB partitions, panels behind fires and fuse boxes, airing-cupboard linings
- Floors — vinyl and thermoplastic floor tiles and the bitumen mastic adhesive beneath them
- Heating systems — pipe lagging, boiler components, flue pipes, rope seals and gaskets
- Lofts — loose-fill insulation, cold-water tanks, AIB around tanks and hatches
Visual identification is unreliable — only laboratory analysis of a sample can confirm asbestos. Our room-by-room reference guide to asbestos-containing materials covers each material's year range, appearance and risk level, and our guide to what asbestos looks like covers identification in more depth.
What condition is the UK's asbestos in?
In the ATaC/NORAC 2021/22 sample, 507,612 of 710,433 asbestos items had some damage, or 71%. Of those damaged items, 459,027 had low damage. The report grouped 22% of all items as licensable materials and 78% as non-licensable materials. These classifications do not mean that 78% required licensed or notifiable handling; the proposed work needs a separate assessment.
These were real survey records, but their coverage was selective. Domestic properties made up 73% of sites and were overwhelmingly social housing. The condition figures combine domestic and non-domestic properties, so they cannot be presented as the percentage of all UK homes with damaged asbestos or as a direct measure of occupants’ exposure.
Is there a national asbestos register?
No — as of 2026 the UK has no national asbestos register. Information about which buildings contain asbestos is held building by building, by the individual dutyholders required to compile and maintain an asbestos register for their own non-domestic premises under Regulation 4 of the Control of Asbestos Regulations 2012 — see our guide to the duty to manage asbestos. Private homes fall outside the duty altogether, apart from the common parts of flats and maisonettes.
The gap is a live political issue. In April 2022, the House of Commons Work and Pensions Committee recommended that the Government commit to removing asbestos from non-domestic buildings within 40 years and develop a central digital register of asbestos in those buildings. The Government published its response in July 2022, and campaigners were still pressing the case in a dedicated Commons debate on a national register on 13 September 2023 — the debate in which ResPublica's 1.5-million-buildings estimate was cited. No national register has been established.
How dangerous is the asbestos still in place?
HSE estimates that past asbestos exposure causes around 5,000 deaths annually in Great Britain. Its July 2026 release recorded 2,146 mesothelioma deaths provisionally in 2024 and 503 deaths mentioning asbestosis without mesothelioma. There were also 395 new pleural-thickening cases assessed for Industrial Injuries Disablement Benefit in 2024, compared with 390 in 2023. These are different measures and should not be added together.
The risk in a building depends on the material, its condition and whether it can release fibres. Materials in good condition and protected from disturbance can often remain in place under appropriate management. Drilling, sanding, scraping or breaking suspect materials can release fibres; obtain competent advice before work and do not assume that a negative visual inspection makes disturbance safe.

Frequently asked questions
How many homes in the UK have asbestos?
There is no comprehensive count of UK homes containing asbestos. A selected 2021/22 survey sample found it in 86% of 94,116 domestic properties, but almost all were social housing. That percentage must not be applied to all UK households.
Where does the "1.5 million buildings" asbestos figure come from?
ResPublica cited that historical estimate in its 2019 report, alongside a six-million-tonne figure connected to older estimates and imports. It is a campaign-era estimate, not a current count of homes, and should retain its source and date.
Does my house contain asbestos if it was built before 2000?
Possibly. HSE advises that buildings built before 2000 may contain asbestos. Age and appearance cannot confirm or exclude it in a particular material. A competent assessment may involve appropriately controlled sampling and laboratory analysis, or presuming asbestos is present and planning controls accordingly.
Is it safe to live in a house that contains asbestos?
Materials in good condition and protected from disturbance can often be managed in place. Damaged or vulnerable materials need competent assessment and appropriate action. Do not sand, drill, scrape or break suspect materials while their identity and safe work arrangements remain unresolved.
Does the duty to manage asbestos apply to private homes?
Regulation 4 applies to non-domestic premises and common parts of residential buildings, rather than the inside of individual private dwellings. However, employers and contractors working inside homes still have duties to assess and prevent asbestos exposure. Northern Ireland has separate asbestos regulations.
How do I find out whether my home contains asbestos?
Use a competent asbestos surveyor and a laboratory with appropriate UKAS accreditation for sample analysis. The scope must match the planned activity: a management survey supports normal use, while refurbishment or demolition requires more intrusive investigation of the affected areas before work. See our survey guide.
For tradespeople and anyone whose work disturbs the fabric of pre-2000 buildings, asbestos awareness training is a legal requirement under Regulation 10 of the Control of Asbestos Regulations 2012. Our CPD-certified Asbestos Awareness Course covers where asbestos hides, how to avoid disturbing it, and what to do if you find it.
Asbestos can remain in pre-2000 buildings; make sure your team can recognise it before they disturb it.
