For small builders and main contractors (UK, focus on England/Wales)
Last reviewed: March 2026
If the building's pre-2000, assume asbestos is on the table. This is how to avoid either doing something daft or walking off jobs you could manage safely.
1. Where asbestos bites you on domestic work
Asbestos turns up on:
- Any house built or refurbished before 2000 - especially 1950s-1980s stock.
- Typical spots: soffits, old flat roofs, Artex/texture coatings, AIB soffits/boxing, old vinyl tiles and bitumen, warm-air systems, old fuse boards, garage roofs, flue pipes, boiler cupboards.
Legally, the heavy "duty to manage" sits on non-domestic and common-parts dutyholders, but as the builder you're still responsible for not exposing your lads or the family.
Rule of thumb: if it's pre-2000 and you're cutting, drilling, grinding or stripping back to structure, you need to think "asbestos" before you start.
2. Surveys - management vs refurbishment
Two main survey types you need to understand:
Management survey
- For buildings in normal use - shops, offices, blocks etc.
- Identifies asbestos in accessible areas so the owner can manage it day-to-day.
Refurbishment/demolition (R&D) survey
- Fully intrusive, done before you start major refurb or demo.
- Designed to find all asbestos that your work is likely to disturb in the work area.
- This is the one you care about on domestic rip-outs, lofts, re-wires, re-roofs, garage demos etc.
If you're pricing big invasive work on a pre-2000 house, your safest move is:
- Tell the client up front: "This needs an asbestos refurb survey before we start stripping - that's your responsibility to arrange."
- Price on the basis that if asbestos is found, there'll be a variation for delays and specialist removal.
3. Licensed vs non-licensed work (builder's version)
You don't need to memorise the full law, but you do need this split:
Licensed work (specialist contractor only)
- High-risk, friable stuff like lagging, sprayed coatings, and most asbestos insulating board (AIB) in anything more than tiny, strictly controlled tasks.
- Large-scale removal or work with high potential exposure - especially on refurbs/demolitions.
- Must be done by an HSE-licensed asbestos contractor, usually with 14-day HSE notification.
Non-licensed work (still controlled)
- Lower-risk, non-friable materials like asbestos cement sheets, some floor tiles, bitumen, textured coatings, in small/short-duration jobs.
- Still needs risk assessment, proper method, PPE/RPE and correct waste handling - it's not "do what you like".
- HSE's Asbestos Essentials sheets show what non-licensed work they expect small builders/trades to do and how, down to task level.
If you're not sure whether something is licensed or not: assume you shouldn't touch it and get a specialist to call it.
4. What to do if you discover suspect asbestos mid-job
If you hit something that might be asbestos while working:
Stop work immediately
Don't keep cutting, drilling or ripping. You're just putting more fibres in the air.
Keep people out and avoid disturbing it
Clear the area, shut the door or tape off, and turn off any ventilation that could spread fibres.
Do not sweep, vacuum or dry scrape
No brooms, no standard vacs, no scraping - that's how you spread contamination.
Tell the client and arrange sampling/survey
Get a UKAS-accredited lab/surveyor to sample and identify the material.
If it's positive, agree next steps: licensed contractor vs controlled non-licensed removal, timescales and cost.
Only restart when you've got the all-clear or a plan
Either written confirmation it's not asbestos, or a clearance note after removal.
Put simply: stop, contain, confirm. Don't guess.
5. Planning jobs so asbestos doesn't wreck you
On any pre-2000 refurb:
- Ask early: "Any asbestos info or old surveys on the place?"
- If it's invasive (re-wire, full rip-out, knocking through, re-roof, garage conversion, loft, bathroom/kitchen strip to brick):
- Recommend a refurbishment survey over the work area before you start.
- Build in time and a provisional sum for asbestos if found.
- For small works:
- If you're just drilling a few holes in obviously newer plasterboard or fixing to recent stud, you might manage risk with basic checks and controls.
- If the substrate is unknown, old, or looks like AIB/old cement, don't take chances - get it checked or avoid disturbing it.
6. Training and paperwork - minimum decent standard
HSE expect anyone who might disturb asbestos to have at least asbestos awareness training.
For a small builder, that means:
- You and your key lads doing a UKATA/IATP-style awareness course every couple of years.
- Having a simple written procedure:
- How you check for asbestos pre-start.
- What you do if you hit suspect stuff (see section 4).
- When you call a surveyor/licensed contractor.
Keep:
- Copies of any asbestos surveys.
- Lab results.
- Removal/clearance certificates.
Those go in the job file with your other H&S and handover docs.
7. Where people go badly wrong
Usual sins on domestic jobs:
Assuming "it's just a house, not a factory"
Plenty of houses have more ACMs than some small commercial units.
Smashing through Artex/AIB/soffits with no thought
Especially on ceilings, boiler cupboards, old pipe boxings and garage roofs.
Dry sweeping and hoovering dust after
That spreads contamination and makes a small incident into a full clean-up job.
Working off zero paperwork
No survey, no sampling, no record - then everyone argues later about what was there and who exposed who.
Thinking "non-licensed" = safe and unregulated
Non-licensed work still needs method, PPE/RPE, proper waste disposal - it's just a different legal category.
8. Simple rules to drum into the team
- If the building is pre-2000, assume asbestos is there until proven otherwise.
- If you don't know what it is and you're about to cut, drill, or rip it - stop and check.
- If you uncover something that looks like asbestos mid-job: stop, keep out, get it tested, then decide.
- Don't try to be a bargain-basement asbestos remover. If in doubt, bring in someone who knows exactly what they're doing.
Handled right, asbestos is a planning and organisation problem, not a reason to panic or bury your head.

Common questions
Who pays for an asbestos survey?
On commercial premises, the duty-holder (usually the building owner) pays. On domestic refurbs, the homeowner is liable. If a client refuses to commission a Refurbishment & Demolition survey before you start, you should walk off the job. Don't accept verbal assurances that 'it's all clear'.

Do I have to report asbestos disturbance?
Yes, in most cases. Any uncontrolled disturbance must be reported to your employer or the duty-holder. Licensed asbestos work and dangerous occurrences must also be reported to HSE under RIDDOR. Stop work, isolate the area, and get a licensed contractor in. Don't try to clean it up yourself.
