Asbestos Renovation Checklist: What to Do Before You Start Any Building Work
Renovation work in a pre-2000 property without an asbestos check is one of the most common ways people are exposed to asbestos fibres. This checklist covers every step — from planning to completion — so you can renovate safely and legally.

Asbestos in good condition, left undisturbed, does not release fibres. The risk comes from disturbance — and renovation work is the most common source of disturbance in domestic properties. Sanding an Artex ceiling. Lifting old floor tiles. Drilling through a partition wall. Removing a boiler and its lagging. Each of these activities, in a pre-2000 property, carries a real risk of asbestos exposure if the materials have not been checked first.
The HSE estimates that around 5,000 people die each year in the UK from asbestos-related diseases. Many of those deaths trace back to brief, apparently minor exposures — a weekend renovation, a single drilling job, a ceiling that was sanded and painted. The fibres are invisible. The diseases take 20–50 years to develop. By the time symptoms appear, the exposure is decades in the past.
The Control of Asbestos Regulations 2012 (CAR 2012) requires that a refurbishment or demolition survey is carried out before any work that could disturb building materials in a pre-2000 building. This is not optional guidance — it is a legal requirement. Builders and contractors who proceed without a survey are committing a criminal offence, and so are the clients who instruct them to do so.
Management Survey ≠ Refurbishment Survey
A management survey identifies ACMs in accessible areas under normal conditions. It does not involve destructive inspection. Before renovation work, a refurbishment survey is required — this is an intrusive survey that inspects the specific areas to be worked on, including inside walls, floors, and ceilings. If you have a management survey but not a refurbishment survey, you do not have the information you need to start building work safely.
Where Asbestos Is Commonly Found in Pre-2000 Properties
Before planning any renovation, check whether your work zone includes any of these materials. If it does, a refurbishment survey is required before work begins.
| Material |
|---|
Artex and textured coatings Medium — low risk if intact, high risk if sanded or scraped |
Asbestos cement sheets Low to medium — friable when weathered or broken |
Asbestos insulation board (AIB) High — friable, releases fibres easily when disturbed |
Pipe lagging High — very friable, releases fibres on any contact |
Floor tiles and adhesives Low to medium — risk increases if tiles are broken or adhesive disturbed |
Loose-fill insulation Very high — highly friable, airborne fibres released immediately on disturbance |
Roof slates and tiles Low — risk increases if tiles are broken during removal |
The Complete Renovation Checklist
Work through this checklist in order. Do not start the next phase until the current one is complete.
Before you plan
Confirm the property was built before 2000
Any building constructed before 2000 may contain asbestos. If yours was, asbestos must be considered before any renovation work begins.
Check for an existing asbestos survey report
If a management survey has been carried out, review it before planning work. If no survey exists, commission one before proceeding.
Commission a refurbishment survey for the affected areas
A management survey is not sufficient for renovation work. A refurbishment survey is required — it involves intrusive inspection of the specific areas to be worked on.
Identify all ACMs in the work zone
The refurbishment survey will identify all asbestos-containing materials in the areas to be disturbed. Review the report carefully before finalising your renovation plans.
Before you start
Arrange removal of any ACMs in the work zone
ACMs that will be disturbed by the renovation must be removed before work begins. Do not attempt to work around them — any disturbance releases fibres.
Confirm the contractor is licensed (if required)
Removal of asbestos insulation board, sprayed coatings, and loose-fill insulation requires a licensed contractor. Asbestos cement and Artex in good condition may be non-licensed work — but always confirm with a surveyor.
Obtain a 4-stage clearance certificate after removal
Before renovation work begins in the cleared area, obtain the 4-stage clearance certificate from an independent analyst. This confirms the area is safe.
During work
Brief all contractors on asbestos risks
Every contractor working in a pre-2000 building must be briefed on the location of known ACMs and the procedures for dealing with unexpected finds.
Stop work immediately if suspected ACMs are found
If unexpected materials are found that could contain asbestos, stop work, seal the area, and commission a sample analysis before continuing.
Do not disturb ACMs that are not being removed
ACMs outside the work zone must not be disturbed. If renovation work requires access to areas with known ACMs, commission a separate removal before proceeding.
After work
Update the asbestos register
After removal and renovation, update the asbestos register to reflect what was removed and what remains. Keep all documentation — survey reports, clearance certificates, waste transfer notes.
Retain all documentation
Keep the refurbishment survey report, the removal contractor's RAMS, the 4-stage clearance certificate, and the waste transfer note. These are the legal record that the work was done correctly.
What to Do If You Find Suspected Asbestos During Renovation
Stop work immediately. Do not continue, do not try to remove the material yourself, and do not disturb it further. Seal the area if possible — close doors, seal gaps with tape, and keep people out. Call a licensed asbestos contractor to assess and sample the material. If the material has already been disturbed and fibres may have been released, vacate the area and contact a specialist for air testing before re-entry.
This is not an overreaction. Asbestos fibres are invisible, odourless, and do not cause immediate symptoms. The only way to know whether the air is safe is to test it. Air testing after an accidental disturbance takes a few hours and gives you a definitive answer. Continuing to work in an area where fibres may have been released is not a risk worth taking.
Telling Your Builder About Asbestos
Under the Construction (Design and Management) Regulations 2015, clients have a legal duty to provide pre-construction information — including asbestos survey reports — to contractors before work begins. If you have a survey report, give it to every contractor working on the project. If you do not have one, commission one before instructing any contractor to start work. A builder who proceeds without this information is taking a legal risk, and so are you.
How Pro Asbestos Removal Supports Your Renovation
We work with homeowners, builders, and project managers across Surrey and South London to make sure renovation projects start safely. We carry out refurbishment surveys, remove ACMs before work begins, and provide the 4-stage clearance certificate that confirms the area is ready for your contractors. We can also advise on whether specific materials in your property require licensed removal or whether non-licensed work is appropriate.
If you are planning a renovation and are not sure whether asbestos is a concern, call us. We will give you a straight answer based on the age and type of your property — no obligation, no pressure.
