Asbestos is found in millions of UK properties built before the year 2000. Despite a complete ban in 1999, it remains present in homes, commercial buildings, schools and industrial premises across London and the South East. The challenge is that asbestos is not always easy to spot and disturbing it without knowing it is there can have serious consequences for your health.
This guide explains what asbestos looks like, the most common places it is found, how professional testing works, and what removal typically costs. If you suspect asbestos in your property, the guidance below will help you understand your next steps.
| Important: Never attempt to drill, cut, sand or remove materials you suspect may contain asbestos. Disturbing asbestos releases microscopic fibres that can cause serious lung disease, including mesothelioma and asbestosis. Always contact a licensed contractor first. |
What Does Asbestos Look Like?
This is one of the most common questions people ask, and the honest answer is: you cannot reliably identify asbestos by sight alone. Asbestos fibres are microscopic. What you can sometimes identify is the material that contains asbestos, known as an asbestos-containing material or ACM.
There are three main types of asbestos that were used commercially in the UK. Each has slightly different visual characteristics, though all require laboratory testing to confirm.
| Type | Common name | Typical appearance | Risk level |
| Chrysotile | White asbestos | White or greyish, fine curly fibres; often found in textured coatings, floor tiles and cement sheets | High – still dangerous |
| Amosite | Brown asbestos | Brown or grey, straight brittle fibres; commonly found in insulation boards and ceiling tiles | Very high |
| Crocidolite | Blue asbestos | Blue or lavender, fine straight fibres; found in spray coatings and pipe insulation | Extremely high – most dangerous type |
In practice, asbestos-containing materials often look perfectly ordinary. A ceiling tile, a floor tile, a roofing panel or a section of pipe lagging may all contain asbestos without any outward sign. Age and condition offer clues but not certainty
| Did you know? Around 1.5 million commercial buildings in the UK are estimated to still contain asbestos, according to the Health and Safety Executive (HSE). Many homeowners are unaware their property contains it. |
Where Is Asbestos Most Commonly Found?
Asbestos was used in construction throughout most of the twentieth century because of its fire resistance, insulating properties and durability. It was banned in the UK in 1999, so any building constructed or refurbished before that date could contain it.
The most common locations include:
- Textured coatings: Artex and textured wall and ceiling coatings (particularly in homes built between 1960 and 1985)
- Tiles: Ceiling and floor tiles, particularly vinyl floor tiles with bitumen adhesive
- Insulation: Pipe lagging and boiler insulation in older heating systems
- Roofing and external panels: Asbestos cement roofing, guttering and soffit boards
- Insulation boards: Insulating boards used in partition walls, around fireplaces and as fire-check doors
- Hidden locations: Behind bath panels, under flooring and inside roof spaces
- Structural coatings: Sprayed coatings on structural steelwork in commercial and industrial buildings
Buildings from the 1950s through to the late 1990s are the highest risk, though pre-war properties can also contain asbestos imported before widespread domestic use began. If your property was built before 2000, it is worth having a professional survey carried out, particularly before any renovation work.
How to Spot Asbestos: Visual Clues to Look For
While visual identification is never conclusive, certain signs can indicate that a material is worth having tested professionally. Look out for:
- Materials in properties built before 2000 that appear fibrous, layered or corrugated when damaged or broken
- Ceiling coatings with a stippled or swirled pattern, particularly in rooms decorated before 1985
- Soft, crumbling or powdery insulation around old pipes or behind heating equipment
- Grey or brown board panels used in partition walls, behind fireplaces or as ceiling tiles
- Corrugated cement sheets on garage roofs, outbuildings or fascia boards that appear weathered or cracked
- Old floor tiles that are brittle, cracked or have a black bitumen adhesive beneath them
| Important: Do not touch, probe or attempt to take a sample yourself. Even handling suspected asbestos-containing materials briefly can release fibres. Only accredited analysts should take samples for testing. |
How to Test for Asbestos
The only reliable way to confirm whether a material contains asbestos is laboratory analysis. There are two main routes:
Professional asbestos survey
A qualified surveyor inspects the property, takes samples from suspect materials and sends them to an accredited laboratory for analysis. Survey reports confirm the presence, type, condition and risk level of any asbestos found, and include a management plan. There are two types:
- Management survey: Carried out before sale, purchase or general management of a building. Minimally intrusive and covers accessible areas.
- Refurbishment and demolition (R&D) survey: Required before any demolition or significant refurbishment. More intrusive and covers areas that will be disturbed by the works.
Bulk sampling
A licensed contractor can take a targeted sample from a specific material for laboratory testing. This is suitable when there is a single suspect material rather than a whole-building concern. Samples are analysed using polarised light microscopy (PLM) or transmission electron microscopy (TEM) to identify fibre type and concentration.

How Much Does It Cost to Remove Asbestos?
Asbestos removal costs in the UK vary considerably depending on the type of material, its location, the quantity involved and whether a licensed or non-licensed contractor is required. Below is a general guide to typical costs based on common job types.
| Job type | Typical cost range | Notes |
| Asbestos survey (management) | £200 – £400 | Single residential property; includes lab analysis |
| Asbestos survey (R&D) | £400 – £1,000+ | Larger or more complex properties |
| Artex / textured coating removal | £500 – £2,000 | Depends on room size and access |
| Asbestos cement roof removal | £1,000 – £4,000+ | Garage or outbuilding; requires licensed contractor |
| Floor tile removal | £300 – £1,500 | Depends on area and adhesive type |
| Pipe lagging removal | £500 – £3,000+ | High risk; licensed removal required |
| Insulation board removal | £500 – £2,500 | Partition walls, fireplaces, ceiling tiles |
These are indicative figures only. A proper quote requires a site assessment. Jobs involving friable or high-risk materials (such as sprayed coatings or pipe lagging) must be carried out by a contractor holding a licence issued by the Health and Safety Executive (HSE).
You can verify any asbestos contractor’s licence status on the HSE asbestos licensed contractors register. Abastra’s licence has been continuously held since 1989 and was renewed until 2027.

How Is Asbestos Removed? What the Process Involves
Asbestos removal is a controlled process governed by the Control of Asbestos Regulations 2012 and, for higher-risk materials, requires a contractor licensed by the HSE. Here is what a professional removal typically involves:
- Survey and risk assessment – A licensed surveyor confirms the type, extent and condition of the ACM before any work begins.
- Notification – For licensed work, the contractor must notify the relevant enforcing authority (HSE or local authority) at least 14 days in advance.
- Enclosure and negative pressure unit – The work area is sealed with polythene sheeting and a negative pressure unit (NPU) is set up to prevent fibres escaping into adjacent areas.
- Removal – Workers in full PPE (including respirators and disposable coveralls) carefully remove the ACM using wet methods to suppress fibre release.
- Decontamination – The work area is thoroughly cleaned using HEPA vacuums and damp wiping. Air testing is carried out before the enclosure is removed.
- Waste disposal – All asbestos waste is double-bagged, labelled as hazardous waste and transported by a licensed carrier to an approved disposal site. A waste consignment note is issued.
- Clearance certificate – An independent UKAS-accredited analyst issues a four-stage clearance certificate confirming the area is safe to reoccupy.
| Why this matters: Attempting DIY asbestos removal is illegal for licensable work and extremely dangerous for any ACM. Prosecution, significant fines and long-term health consequences are all possible outcomes. Always use a licensed contractor. |

Frequently Asked Questions
Can I identify asbestos just by looking at it?
No. Asbestos fibres are invisible to the naked eye. You can look for materials that are consistent with ACMs – such as textured coatings, corrugated cement sheets or old insulation board – but only laboratory testing can confirm the presence of asbestos.
Is asbestos dangerous if it is in good condition?
Asbestos that is intact, undamaged and unlikely to be disturbed poses a low risk. The danger arises when fibres are released into the air, which happens when ACMs are cut, drilled, sanded or disturbed. In such cases, monitoring and management in place may be appropriate rather than immediate removal.
Do I need a survey before renovation work?
Yes. If your property was built before 2000 and you are planning to remove walls, replace flooring, re-roof or carry out any work that involves disturbing building materials, a refurbishment and demolition survey is legally required before work begins.
How long does asbestos removal take?
It depends on the scope of work. A single room of textured coating might take one to two days including air testing and clearance. A larger commercial project involving insulation boards or pipe lagging may take several days or more. Your contractor will confirm timescales after the survey.
What is the difference between white, brown and blue asbestos?
All three are dangerous, though crocidolite (blue) and amosite (brown) are considered the highest risk due to the shape and durability of their fibres. Chrysotile (white) was the most widely used and is still found in many ACMs. All types are subject to the same legal controls in the UK.
Can I legally remove asbestos myself?
In very limited circumstances, non-licensable work (such as removing a small section of asbestos cement in a controlled way) may be carried out without a licence, but it is still subject to strict controls under the Control of Asbestos Regulations 2012. For any licensable material – including most insulation, lagging and sprayed coatings – a licensed contractor is a legal requirement.
