Licensed vs Non-Licensed Asbestos Removal
Which asbestos removal regime applies — licensed or non-licensed — depends on the material, not the size of the job. A UK dutyholder comparison.
Key takeaways
- AIB ceiling panels in a 1970s office → Licensed removal, full enclosure, 4-stage clearance
- Pipe lagging in a school plant room → Licensed removal, decant of the classroom block
- Boiler insulation replacement in a hospital → Licensed removal, phased with the shutdown window
- Corrugated cement garage roof at a domestic property → Non-licensed removal by an ACAD contractor
- Textured coating (Artex) removal for a kitchen refit → Non-licensed removal with local dust-suppression sheeting
CAR 2012 splits asbestos removal into three regimes: licensed, notifiable non-licensed (NNLW) and non-licensed. This guide compares licensed vs non-licensed head-to-head — cost, containment, air monitoring and the survey you need first. The NNLW middle ground is covered in its own guide.

Answer 2–3 questions to get a specific survey recommendation.
Question 1
What material is being removed?
Head-to-head comparison
Licensed and non-licensed work look completely different on site. The table shows what changes across the same 10 dutyholder criteria.
| Criterion | Licensed removal | Non-licensed removal |
|---|---|---|
| Typical materials | AIB, lagging, sprayed coatings, high-density insulation | Bonded cement, most textured coatings, floor tiles, gaskets, ropes |
| Contractor licence | HSE 3-year licence required | No HSE licence required |
| Notification | 14-day ASB5 notice to HSE before work | None (unless material becomes NNLW — see separate guide) |
| Enclosure | Fully sealed negative-pressure enclosure | Simple dust-suppression sheeting |
| Air monitoring | Background + leak + 4-stage clearance mandatory | Not required by law; reassurance test recommended |
| Medical surveillance | Mandatory 3-yearly for all operatives | Mandatory only where NNLW threshold exceeded |
| Waste classification | Hazardous — consigned via HWCN | Hazardous — consigned via HWCN |
| Typical UK cost | £1,800–£12,000+ per job | £350–£3,500 per job |
| Timing on site | 3–10+ days including clearance | 0.5–2 days typical |
| Survey required first | R&D Survey by UKAS 17020 body | R&D Survey by UKAS 17020 body |
What this means
The material dictates the regime, not the size of the job. A single square metre of AIB is still licensed work; a whole garage roof of cement usually is not.
Licensed removal — pros and cons
Used for the most hazardous materials — AIB, pipe lagging, boiler insulation, sprayed coatings and any friable high-fibre-release ACM.
Pros
- Highest containment standard on the UK market — negative-pressure enclosure and 4-stage clearance
- Independent UKAS air monitoring provides written proof the area is safe to reoccupy
- HSE licence and mandatory medical surveillance give a strong audit trail for insurers
- Correct regime for the highest-risk materials — no ambiguity for the dutyholder
Cons
- Highest cost bracket — enclosure, PPE, decontamination unit and clearance all bill separately
- 14-day HSE notification adds calendar time before work can start
- Occupied buildings usually need decant of the affected area
- Requires an independent analyst to break the contractor's commercial interest — never use the removal contractor's own analyst
Non-licensed removal — pros and cons
Used for bonded cement, most textured coatings, vinyl floor tiles, bitumen adhesive, gaskets and rope seals — materials where fibre release under controlled removal is low.
Pros
- Lower cost — no enclosure, no HSE notification and shorter site time
- Faster mobilisation — a competent contractor can be on site the same week
- Suitable for outdoor cement removals with dust-suppression only
- No decant needed for small internal jobs where the area can be sealed off
Cons
- No clearance certificate — the dutyholder should still commission a reassurance air test
- Contractor competence is uneven in the market — the ACAD register is the practical UK short-list
- Any change in condition (damaged AIB, friable lagging) pushes the job into licensed territory mid-project
- Waste is still hazardous and must be consigned correctly — a common area of non-compliance
Recommended scenarios
In practice the material is confirmed by an R&D Survey and the regime follows. The examples below show which regime the survey typically recommends.
- •AIB ceiling panels in a 1970s office → Licensed removal, full enclosure, 4-stage clearance
- •Pipe lagging in a school plant room → Licensed removal, decant of the classroom block
- •Boiler insulation replacement in a hospital → Licensed removal, phased with the shutdown window
- •Corrugated cement garage roof at a domestic property → Non-licensed removal by an ACAD contractor
- •Textured coating (Artex) removal for a kitchen refit → Non-licensed removal with local dust-suppression sheeting
- •Vinyl floor tiles with bitumen adhesive in a retail unit → Non-licensed removal overnight
What this means
The R&D Survey is the routing document — match the survey type to the works, then let the survey route each ACM to the correct removal regime.

The independent-analyst rule
For any licensed removal, the analyst carrying out the 4-stage clearance must be independent of the removal contractor. HSG248 makes this explicit and the HSE audits it. Non-licensed jobs are not required by law to have air testing but a reassurance test from an independent UKAS 17025 lab is best practice and cheap insurance for the dutyholder.
What this means
Never accept air testing carried out by the removal contractor's own analyst — the certificate has no independent evidential weight.
Recommended next step
In practice, the choice above turns on the facts of your building and the works. If you'd rather have an independent consultant confirm the recommendation in writing, request a fixed-price R&D Survey quote. The R&D Survey is the routing document that confirms which regime applies to each ACM — we do not carry out removal ourselves, so the recommendation is evidence-led. Elements Surveying Group is UKAS 17025 accredited, does not own a removal arm and does not take referral fees — the recommendation is evidence-led, not commercial.
- •Request a fixed-price R&D Survey quote — one working day turnaround
- •Speak to a senior consultant on 0208 036 1099 (Mon–Fri, 8am–6pm)
- •Independent, UKAS-accredited, conflict-free — no removal arm, no referral fees
What this means
If the comparison still leaves doubt, request a quote — the enquiry costs nothing and puts the decision in writing from an independent, accredited consultancy.
Frequently asked questions
Who decides which regime applies?
The R&D Survey identifies the material and its condition; the HSE Analysts' Guide (HSG248) and CAR 2012 dictate the regime that follows. It is not a commercial choice.
Can a licensed contractor do non-licensed work?
Yes — most do. The licence sets the minimum standard, not the maximum. A non-licensed contractor cannot however do licensed work.
Do I need a 4-stage clearance for non-licensed removal?
No — a reassurance air test is sufficient and is what most competent dutyholders commission.
Is the waste treated the same?
Yes — both licensed and non-licensed asbestos waste is classified as hazardous waste and must be consigned via a Hazardous Waste Consignment Note.
