What Percentage of Buildings Built Before 2000 Contain Asbestos?
If your building was constructed before the year 2000, there is a very real chance it contains asbestos. The HSE estimates that around half of all UK buildings built before 2000 may contain asbestos-containing materials (ACMs) — and that figure rises sharply for structures dating from the 1950s, 60s and 70s, when asbestos use was at its absolute peak.
Understanding what percentage of buildings built before 2000 contain asbestos is not simply an academic exercise. It directly affects your legal obligations, your renovation plans, and the safety of everyone who uses your property.
This is not a niche problem confined to derelict industrial sites. Asbestos was used extensively in schools, hospitals, offices, and ordinary family homes right up until the UK’s comprehensive ban took effect in 1999. If you own, manage, or are planning work on an older property, this issue almost certainly applies to you.
Why Asbestos Was Used So Widely in Older Buildings
Asbestos was not used carelessly — it was genuinely considered a wonder material. Naturally fire-resistant, thermally insulating, chemically stable, and cheap to source, it was enthusiastically specified by builders and architects across virtually every building type and construction method for decades.
Use peaked between the 1930s and the late 1970s. During this period, asbestos was incorporated into hundreds of different building products — from roof sheets and floor tiles to textured decorative coatings and pipe lagging.
Even after concerns about its health effects began to emerge in the 1970s and 1980s, certain asbestos products remained in legal use. The result is a vast legacy of ACMs distributed across the UK’s building stock — much of it still in place, often undisturbed, and frequently unknown to current owners and occupants.
How Building Age Affects Asbestos Risk
Not all pre-2000 buildings carry the same level of risk. The era in which a property was constructed has a significant bearing on both the likelihood of asbestos being present and the types of materials involved.
Buildings from the 1930s to 1950s
Properties from this era carry some of the highest asbestos risk. Sprayed asbestos coatings were applied to structural steelwork for fire protection, and asbestos insulation boards were commonly fixed to walls and ceilings.
These materials tend to be more friable — meaning they can release fibres more easily when disturbed — making them particularly hazardous. If you are responsible for a property of this age, a professional survey is not optional; it is essential.
Buildings from the 1960s and 1970s
This was the peak period for asbestos use across the UK. System-built schools, local authority housing, commercial offices, and industrial units were all constructed using a wide range of ACMs.
Textured coatings such as Artex were applied to millions of ceilings during this period, and asbestos cement products were used extensively in roofing and cladding. Buildings of this vintage are statistically among the most likely to contain multiple types of ACMs throughout their fabric.
Buildings from the 1980s and 1990s
Even as awareness of asbestos dangers grew, many products remained in legal use throughout the 1980s and into the 1990s. Chrysotile (white asbestos) was not banned until 1999, meaning buildings constructed or refurbished right up to that point may still contain it.
Floor tiles, gaskets, and certain insulation products from this era should never be assumed to be asbestos-free without proper testing. The 1980s and 1990s are decades that property owners frequently underestimate when assessing their risk.
Where Is Asbestos Typically Found in Pre-2000 Buildings?
Knowing where asbestos is likely to be found helps property owners and managers understand the full scope of the risk. The following materials were routinely manufactured with asbestos and are frequently identified during professional surveys:
- Textured coatings — Artex and similar decorative ceiling and wall finishes applied from the 1960s through to the 1990s
- Asbestos insulation board (AIB) — Used in ceiling tiles, partition walls, fire doors, and around boilers and pipework
- Pipe lagging — Thermal insulation applied to heating pipes, particularly in boiler rooms and plant areas
- Sprayed asbestos coatings — Applied to structural steelwork and concrete for fire protection, common in industrial and commercial buildings
- Asbestos cement products — Roof sheets, gutters, downpipes, and wall cladding panels, widely used in agricultural and industrial buildings
- Vinyl and thermoplastic floor tiles — Frequently contained asbestos fibres, particularly those installed before the mid-1980s
- Linoleum flooring — Older linoleum products and their adhesive backings may contain asbestos
- Roofing felt and bitumen products — Certain felt underlays and bitumen-based products used in flat roofing contained asbestos
- Boiler and furnace insulation — Lagging and blanket insulation around heating plant frequently used asbestos as a primary component
- Window putty and glazing compounds — Some older compounds contained asbestos as a filler and binder
This list is not exhaustive. Professional surveyors regularly identify asbestos in locations that genuinely surprise building owners — including behind wall tiles, within partition systems, and in areas that appear to have been refurbished relatively recently.
The Health Risks: Why the Percentage Matters
Asbestos fibres, when disturbed, become airborne. Once inhaled, they lodge permanently in lung tissue and can cause serious, life-threatening diseases — often with a latency period of 20 to 50 years between exposure and diagnosis.
The HSE reports that asbestos-related diseases cause approximately 5,000 deaths in the UK each year — more than any other single work-related cause of death. The primary diseases associated with asbestos exposure include:
- Mesothelioma — A cancer of the lining of the lungs or abdomen, almost exclusively caused by asbestos exposure and invariably fatal
- Asbestos-related lung cancer — Carries a similar risk profile to mesothelioma, particularly in those who also smoked
- Asbestosis — A chronic scarring of lung tissue caused by prolonged asbestos exposure, leading to progressive breathing difficulties
- Pleural thickening — Scarring of the membrane surrounding the lungs, which can cause breathlessness and chest pain
Crucially, it is not the mere presence of asbestos that creates risk — it is the disturbance of asbestos. ACMs that are in good condition and left undisturbed are generally considered low risk. The danger arises when materials are drilled, cut, sanded, broken, or otherwise disturbed during maintenance or renovation work.
Your Legal Obligations as a Property Owner or Manager
If you are responsible for a non-domestic building that may contain asbestos, you have a legal duty to manage it. This obligation is set out under the Control of Asbestos Regulations and is commonly referred to as the Duty to Manage.
The Duty to Manage requires you to:
- Identify whether asbestos-containing materials are present in your premises
- Assess the condition and risk posed by any ACMs found
- Maintain an up-to-date asbestos register
- Produce and implement an asbestos management plan
- Provide information about ACM locations to anyone who may disturb them
- Arrange periodic re-inspections to monitor the condition of known ACMs
Failure to comply can result in significant fines and, far more importantly, serious harm to building occupants, maintenance workers, and contractors. The HSE’s guidance document HSG264 sets out the standards that surveys must meet, and all reputable asbestos surveyors work to this framework.
For domestic properties, the legal position is different — homeowners are not subject to the Duty to Manage — but the health risks are identical. Anyone planning renovation or demolition work on a pre-2000 home should arrange a survey before work begins.
What Type of Asbestos Survey Do You Need?
Given that such a high proportion of buildings built before 2000 contain asbestos, choosing the correct survey type is essential for both legal compliance and practical safety. The right survey depends on what you intend to do with the building.
Management Survey
A management survey is the standard survey for occupied buildings where no major renovation is planned. It identifies the location, extent, and condition of ACMs that could be disturbed during normal occupancy and routine maintenance.
This is the survey required to fulfil your Duty to Manage obligations under the Control of Asbestos Regulations. If you do not currently have an asbestos register in place for your non-domestic premises, this is where you start.
Refurbishment Survey
Before any significant building work or alteration, a refurbishment survey is required. This is a more intrusive investigation of the specific areas to be disturbed, designed to locate all ACMs before contractors begin work.
It is a legal requirement before any notifiable refurbishment activity. Skipping this step does not just create legal exposure — it puts tradespeople and occupants at direct risk of asbestos fibre release.
Demolition Survey
If a building is to be demolished in full or in part, a demolition survey must be carried out beforehand. This is the most thorough and intrusive survey type, covering the entire structure to ensure no ACMs are missed before demolition work commences.
Without a demolition survey, you risk exposing demolition crews to uncontrolled asbestos fibre release — a serious criminal and civil liability.
Re-inspection Survey
Once an asbestos register is in place, the condition of known ACMs must be monitored over time. A re-inspection survey assesses whether the condition of previously identified materials has changed and whether the risk rating remains appropriate. These are typically carried out annually.
What Happens During a Professional Asbestos Survey?
A professional survey carried out to HSG264 standards follows a clear, methodical process. Here is what to expect when you book with Supernova Asbestos Surveys:
- Booking — Contact us by phone or online. We confirm availability, often with same-week appointments, and send a booking confirmation.
- Site visit — A BOHS P402-qualified surveyor attends at the agreed time and carries out a thorough visual inspection of the property.
- Sampling — Representative samples are collected from suspect materials using correct containment procedures to prevent fibre release.
- Laboratory analysis — Samples are analysed under polarised light microscopy (PLM) at our UKAS-accredited laboratory.
- Report delivery — You receive a detailed asbestos register and risk-rated management plan in digital format within 3–5 working days.
The report is fully compliant with HSG264 guidance and satisfies all legal requirements under the Control of Asbestos Regulations. It includes an asbestos register, a risk assessment for each identified ACM, and a management plan setting out the recommended actions.
Can You Test for Asbestos Yourself?
In some circumstances — particularly for homeowners wanting to check a specific material before undertaking minor DIY work — a testing kit can be a practical and cost-effective first step. Our kits allow you to collect a sample safely and send it to our UKAS-accredited laboratory for analysis.
However, understand the limitations clearly. A testing kit will confirm whether a specific sampled material contains asbestos — it will not tell you whether other materials elsewhere in the building are also affected.
For legal compliance and comprehensive risk management, a professional survey carried out by a qualified surveyor remains the correct route. DIY testing is a useful supplement, not a substitute.
Do You Need a Fire Risk Assessment Too?
Many property managers are surprised to learn that asbestos surveys and fire risk assessment obligations often go hand in hand. Non-domestic premises in the UK are required to have a current fire risk assessment under fire safety legislation, and many of the same building materials that contain asbestos — including fire doors, ceiling tiles, and structural insulation — are also relevant to fire risk.
Supernova Asbestos Surveys can arrange both assessments together, saving you time and reducing disruption to your building’s occupants. Combining both obligations in a single visit is an efficient, practical approach that many of our clients choose.

Taking Action: What to Do Next
If your building was constructed before 2000, the question is not really whether asbestos might be present — statistically, there is a significant chance that it is. The question is whether you know where it is, what condition it is in, and what your obligations are.
For non-domestic property owners and managers, the Duty to Manage under the Control of Asbestos Regulations is a legal requirement, not a recommendation. For homeowners planning any renovation or structural work, a survey before you start is the only way to protect yourself and your tradespeople from an invisible and potentially fatal hazard.
Supernova Asbestos Surveys has completed over 50,000 surveys across the UK. Our BOHS-qualified surveyors, UKAS-accredited laboratory, and HSG264-compliant reports give you everything you need to manage your legal obligations and keep your building safe.

Frequently Asked Questions
What percentage of buildings built before 2000 contain asbestos?
The HSE estimates that around half of all UK buildings constructed before 2000 may contain asbestos-containing materials. This figure is higher for buildings dating from the 1950s, 60s and 70s, when asbestos use was at its most widespread. Even buildings from the 1980s and 1990s can contain asbestos, as certain products — including chrysotile (white asbestos) — remained legal until 1999.
Is asbestos dangerous if it is left undisturbed?
ACMs that are in good condition and remain undisturbed are generally considered low risk. The danger arises when asbestos-containing materials are drilled, cut, sanded, or broken, releasing microscopic fibres into the air. Inhaled fibres can cause serious diseases including mesothelioma, lung cancer, and asbestosis, often with a latency period of 20 to 50 years.
Do I have a legal duty to survey my building for asbestos?
If you are the owner or manager of a non-domestic building, you have a legal Duty to Manage asbestos under the Control of Asbestos Regulations. This requires you to identify ACMs, assess their condition, maintain an asbestos register, and implement a management plan. Domestic homeowners are not subject to the Duty to Manage, but should still arrange a survey before any renovation or demolition work on a pre-2000 property.
What is the difference between a management survey and a refurbishment survey?
A management survey is carried out on occupied buildings with no major works planned. It identifies ACMs that could be disturbed during normal use and routine maintenance. A refurbishment survey is required before any significant building work begins — it is more intrusive and focuses specifically on the areas to be altered. Both surveys must be carried out to HSG264 standards by a qualified surveyor.
How quickly can I get an asbestos survey booked?
Supernova Asbestos Surveys regularly offers same-week appointments across the UK, including London, Manchester, Birmingham, and beyond. Call us on 020 4586 0680 or visit asbestos-surveys.org.uk to check availability and receive a fixed-price quote for your property.
