General knowledge and identification
What is asbestos, and why was it used in buildings?
Asbestos is a group of naturally occurring fibrous minerals. Manufacturers used it for insulation, fire protection and reinforcement. In an older building, it can turn up in a roof sheet, a board behind a heater or insulation around a pipe.
HSE guide to asbestos in buildings
What year of house might contain asbestos?
In Great Britain, a building built or refurbished before 2000 may contain asbestos. A 1970s house with a recently fitted kitchen can still have older boards, floor coverings or coatings elsewhere. Use the building date as a prompt to investigate before work begins.
HSE guidance on building age and asbestos
Where is asbestos commonly found in a house, garage or office?
Possible locations include garage roof sheets, soffits, textured ceilings, vinyl floor tiles, panels around boilers, service ducts and pipe insulation. Products that look alike can have different compositions. A competent surveyor can identify which materials need sampling.
See HSE’s illustrated building diagrams · Ask ASM about a suspect material
Can you tell if something is asbestos from a photo?
A photo can show ASM where the material is and help plan a visit. It cannot confirm whether the material contains asbestos. If the distinction affects planned work, leave the material undisturbed and arrange representative sampling by a competent person.
Read ASM’s guide to identifying asbestos from photographs
Does every Artex or textured ceiling contain asbestos?
No. Some older textured coatings contain asbestos, and others do not. The pattern cannot tell you which coating you have. Before scraping, sanding or installing downlights, check the coating in the actual work area.
Arrange sampling of a textured coating
What do ACM and AIB mean on an asbestos report?
ACM means asbestos-containing material. AIB means asbestos insulating board, one type of ACM. If a report records AIB, give the contractor its location, condition and the proposed work before anyone drills, cuts or removes the board.
Suspected asbestos and immediate safety
I drilled into something that might be asbestos. What should I do now?
Stop drilling immediately, keep other people away and avoid spreading dust. Do not sweep up, use a household vacuum or carry dusty tools through the building. At work, tell the person in charge and follow the site’s asbestos emergency procedure. Get competent advice before anyone cleans the area or restarts work.
HSE advice on accidental disturbance · Contact ASM about the affected area
Why is asbestos dangerous, and who should I speak to about possible exposure?
Breathing airborne asbestos fibres can cause serious disease. If you are concerned about an exposure, speak to your GP and explain when it happened, what you were doing and how long it lasted. At work, also report the incident to your employer so the circumstances can be recorded.
HSE advice on inadvertent exposure
Do I have to remove asbestos if it is in good condition?
Asbestos in good condition can often stay in place if it can be managed safely and is unlikely to be disturbed. Record its location and monitor its condition. Reassess the decision if the material deteriorates or proposed work will reach it.
Managing asbestos in place · When to discuss removal
Should I break off a small piece of suspect material to send for testing?
Leave the material in place and arrange professional collection. Breaking a corner off a board or scraping a coating can release fibres and may give the laboratory an unrepresentative sample. Tell ASM where the material is and what work you were planning.
Choosing a survey and reading a report
What is the difference between a management, refurbishment and demolition asbestos survey?
A management survey supports normal occupation and foreseeable maintenance. A refurbishment survey investigates the areas a particular alteration will disturb. A demolition survey examines the building or part of it that will come down. Tell the surveyor what people will actually do in the building so the scope matches the work.
Compare ASM’s asbestos survey types · HSE survey guidance
Do I need an asbestos survey before a rewire, kitchen refit or bathroom renovation?
If the work could disturb hidden material in a pre-2000 building, check whether existing survey information covers the full work area. A rewire can pass through ceiling voids and walls well beyond the room being renovated. Give the surveyor the proposed cable routes, openings and fixing points to scope a refurbishment survey.
Scope a refurbishment asbestos survey
My homebuyer report mentions possible asbestos. What do I ask for?
Send ASM the relevant extract and say what decision you need to make before purchase. A specific question about one garage roof may call for targeted sampling. If you plan to renovate several rooms, share those plans so the surveyor can advise on wider coverage.
Testing one suspect material · Choosing a property survey
Can we use our management survey to demolish part of a building?
A management survey alone does not establish what is concealed inside the part being demolished. Give the surveyor a demolition drawing that identifies the structure, adjoining areas and services affected. Resolve inaccessible areas within that scope before demolition starts.
Plan a demolition asbestos survey
My survey says “no access” or “presumed asbestos”. Can the contractor go ahead?
A “no access” entry means the surveyor did not inspect that area. “Presumed asbestos” means the material must be treated as asbestos unless suitable evidence establishes otherwise. If the planned work reaches either entry, pause that part of the job and ask the surveyor what further investigation or controls are needed.
HSE guidance on survey coverage · Resolve a gap before refurbishment
Does an asbestos survey expire after a year?
A survey records what the surveyor could establish on the day and within the agreed scope. Its usefulness depends on changes to the building, material condition and the next job. Review the register and management plan regularly. A recent survey can still be unsuitable for a new project if it excluded the work area.
Find out what a re-inspection covers
What does ASM need before surveying an occupied shop, office or school?
Provide floor plans, previous reports, the work brief and access arrangements. Identify occupied areas, restricted rooms and shutdown windows. For intrusive work, agree with the surveyor which areas must be vacated, when access is needed and how the areas will be handed back.
Sampling, lab results and air testing
Do I need one asbestos sample or a survey of the whole property?
Targeted sampling can answer a narrow question about a particular material. Choose a survey when you need to understand several rooms, concealed materials, a contractor’s work area or an estate’s management responsibilities. A sample result applies to the material sampled.
Targeted sample collection · Asbestos surveys for buildings and projects
My sample says “no asbestos detected”. Does that clear the room?
No. The result applies to the submitted sample. Check the sample reference against its location and description. For example, a negative result for a floor tile does not establish what is in the adhesive beneath it or in tiles laid at a different time.
What ASM’s bulk laboratory result covers
My asbestos test is positive. What do I do with the result?
Identify the precise sample location, leave the material undisturbed and tell anyone planning work there. The next decision depends on its condition and what the work will disturb. Ask for advice on management, protection or removal before the programme continues.
Plan how to manage the material · Discuss removal before works
Can an air test tell me whether my ceiling contains asbestos?
No. A bulk test identifies asbestos in a representative piece of material. Air monitoring measures airborne fibre concentration at a stated location during a sampling period. If your question is about the ceiling itself, start with professional material sampling.
Test a suspect material · Understand air monitoring
What is four-stage clearance, and who appoints the analyst?
Four-stage clearance is a formal assessment before an area is handed back after relevant licensed asbestos removal. It includes inspection, a thorough visual check, clearance air monitoring and a final assessment after the enclosure comes down. The client should appoint an independent analytical organisation accredited for the work.
ASM guidance on air monitoring and four-stage clearance
Can I post an already collected asbestos sample to ASM?
ASM’s Sunderland laboratory accepts suitable samples by prior arrangement. Contact the lab before sending anything and follow its acceptance, packaging and identification instructions. If the material is still part of the building, book professional collection.
Landlord, employer and dutyholder questions
Who is responsible for managing asbestos in a commercial building?
In Great Britain, responsibility follows the obligation to maintain or repair the premises, or control of the premises where there is no such obligation. A landlord, tenant or more than one party can have duties. Check the lease and maintenance arrangements, including who controls shared spaces.
HSE’s dutyholder guidance · ASM management plan support
Do landlords need an asbestos survey before letting a house or flat?
Letting a private home does not automatically require a whole-property asbestos survey. The duty to manage can apply to shared areas of residential buildings, such as communal stairs and plant rooms. Before repairs or refurbishment, establish what materials the contractor could disturb inside the home as well.
ASM’s guide for landlords · HSE guidance on premises covered
What is the difference between an asbestos register and a management plan?
The register records where known or presumed asbestos is and its condition. The management plan explains who will act on that information, which actions are due, how condition will be checked and how people will receive the information before work.
See how a register and management plan work together
What asbestos information should I give an electrician or maintenance contractor?
Give the contractor the current register, relevant plans and survey limitations for the exact route of the work. Walk through any entries affecting drilling, fixings or access. If a ceiling void on the route was never inspected, resolve that gap before the contractor enters it.
Information for routine maintenance · Surveying concealed work areas
Our school has an asbestos survey. What else should the estates team check?
Check that the register reflects changes since the survey, each outstanding action has an owner and contractors can obtain the relevant information before starting. A practical check is to pick one planned maintenance job and trace its location from the work order to the register and the contractor briefing.
Removal, demolition and specialist projects
Who can assess an old asbestos cement garage roof for removal?
ASM can review the roof’s location, size, condition and access to scope removal. Send existing test results and photographs taken safely from ground level. Leave the sheets in place and stay off the roof.
Arrange a garage roof removal assessment
Does all asbestos removal require a licensed contractor?
No. The material, condition, task and likely exposure determine whether work is licensable. Higher-risk work, including most work on asbestos pipe insulation, requires an HSE-licensed contractor. Some non-licensed work is notifiable, and all categories require appropriate controls and competence.
HSE guidance on licensed work · Ask ASM to assess a removal scope
Can the soft-strip team start while we wait for the asbestos survey?
Do not start stripping materials where asbestos information for the work is missing. Compare the strip-out drawings with survey coverage, including partitions, soffits, ceilings and concealed services. Resolve gaps and communicate the findings before releasing the affected areas for work.
Principal contractor’s pre-strip survey guide · ASM soft strip-out services
How do we sequence asbestos removal and demolition?
Start with the demolition footprint, the survey and its exclusions. Identify materials that will be disturbed, agree the removal scope and establish which inspections or clearance steps are required before each area is released. Include those handover points in the demolition programme.
Discuss a demolition programme · Plan analytical support
What should a groundworker do if suspect asbestos appears in an excavation?
Stop work in the affected area, keep people away and tell the site manager before more soil is moved. Record the find location without disturbing it. A specialist can review the site investigation, excavation plan and material to determine what sampling, controls or remediation are needed.

How can a project manager check asbestos risks along a new installation route?
Overlay the installation drawings on the survey plans. Trace each penetration, fixing, cable route and access point, including spaces outside the main work area. Send ASM the drawings and programme dates so investigation can be scoped before the installation team arrives.
ASM support for installations and major projects
Can ASM help with asbestos on wind, battery storage or brownfield energy projects?
Yes. ASM supports renewable-energy projects involving existing assets, components and potentially affected land. Identify whether the planned work concerns equipment, a building or ground disturbance, then share the asset records and proposed scope.
Prices, timescales and quotes
How much does a home asbestos survey cost?
ASM’s 2026 guide puts many domestic surveys at £180–£480 plus VAT. Its example for a three-bedroom house is £250–£380 plus VAT. The type of survey matters: an intrusive investigation before refurbishment has a different scope from a management survey for normal occupation.
Check current ASM survey prices and property examples
How much does it cost to test one suspect material?
ASM’s 2026 guide gives £80–£200 plus VAT for professional collection and analysis. Its standard public laboratory-only price is £25 per accepted sample. Choose collection if the material is still in the building. The laboratory-only price applies to a suitable sample already collected.

How much does asbestos garage roof removal cost?
ASM’s 2026 removal guide lists a typical garage roof range of £420–£1,500 or more, plus VAT. Roof size, condition, access and waste handling affect the quote. Ask whether the written scope includes collection, disposal and any replacement roofing you need.
Check ASM’s current removal price guide · Request a garage-specific quote
Why are two asbestos survey quotes for the same building different?
Compare the survey type, areas covered, access arrangements, sampling allowance and reporting timescale. One quote may cover an occupied shop floor while the other includes intrusive access behind counters and above ceilings. Ask each provider to identify exclusions in writing.
What affects an asbestos survey quotation
What should I send ASM for a written quote or a visit date?
Send the postcode, property type, approximate size, planned work and deadline. Attach plans, existing reports and photographs you can take safely. If a contractor is booked, give both the proposed start date and the date they need the report to plan the work.
