HSE CAR 2012 Consultation: What the Four-Stage Clearance Independence Review Means for You
The HSE ran a consultation on improving the Control of Asbestos Regulations 2012 between November 2025 and 9 January 2026. The central issue — whether the analyst who issues your clearance certificate must be genuinely independent from the contractor who removed the asbestos — has direct consequences for every domestic and commercial asbestos removal job in the UK.
Why the Clearance Independence Question Matters
The four-stage clearance procedure under CAR 2012 Regulation 22 is the mechanism that confirms a licensed asbestos enclosure is safe to dismantle and the area safe to reoccupy. It requires an independent analyst — not the removal contractor — to carry out a visual inspection, background air sample, enclosure integrity check, and final air sample. The clearance certificate the analyst issues is the legal record that the work was done correctly.
The problem the HSE consultation was designed to address is that "independent" has not been defined with sufficient precision in the regulations. In practice, some contractors have used in-house analysts, sister companies, or analysts with whom they have a commercial relationship. The conflict of interest is obvious: an analyst who depends on the removal contractor for referrals has a financial incentive to pass clearances that should fail.
Across the jobs we have managed, the most common documentation problem we encounter is a clearance certificate that does not clearly identify the analyst as independent from the removal contractor. In several cases, the certificate has been issued on the same letterhead as the removal company — which is not a valid four-stage clearance under any reading of Regulation 22. This is the pattern the HSE consultation is designed to close.
What the HSE Consultation Covered
The consultation ran from November 2025 and closed on 9 January 2026. It covered four main areas of CAR 2012 application. The response and any proposed regulatory changes have not yet been published as of June 2026.
Analyst independence from the removal contractor
Active enforcement focusThe consultation asked whether CAR 2012 should be amended to make explicit that the analyst carrying out the four-stage clearance procedure must be independent from the contractor who performed the removal. Current Regulation 22 requires an independent analyst but does not define independence with sufficient precision, leading to cases where contractors use in-house analysts or sister companies.
UKAS accreditation for clearance analysts
Under reviewThe consultation explored whether UKAS accreditation for asbestos air testing should become a mandatory requirement for analysts issuing clearance certificates, rather than a recommended best practice. UKAS accreditation means the analyst's methods have been independently assessed against ISO 17025.
Notification requirements for NNLW
Guidance expectedThe consultation reviewed the notification thresholds for Notifiable Non-Licensed Work (NNLW), including whether the current ASB5 notification process adequately protects workers and whether the boundary between NNLW and licensed work is being applied correctly in practice.
Training and refresher requirements
Under reviewThe consultation examined whether the current annual refresher training requirement for licensed asbestos workers is being consistently applied, and whether the training content adequately covers the four-stage clearance procedure and its independence requirement.
What the Independence Requirement Means Right Now
The consultation does not change the existing legal position. CAR 2012 Regulation 22 already requires the four-stage clearance to be carried out by an independent analyst. The consultation is about making that requirement more precise and more consistently enforced — not about introducing a new obligation.
What this means in practice: if you are commissioning licensed asbestos removal today, you should already be asking your contractor who will carry out the clearance and verifying that the analyst is genuinely independent. Waiting for the consultation response to be published before taking this step is not a defensible position if something goes wrong.
The UKAS Accreditation Standard
UKAS accreditation for asbestos air testing (under ISO 17025) is the recognised standard for clearance analysts. You can verify any analyst's accreditation at ukas.com/find-an-organisation. The HSE consultation explored whether UKAS accreditation should become mandatory. Whether or not it does, using a UKAS-accredited analyst is the safest position for property owners and duty holders.
Pro Asbestos Removal uses a UKAS-accredited independent analyst for all four-stage clearances. The analyst is a separate company with no commercial relationship with our removal operations. The clearance certificate we provide identifies the analyst, their UKAS accreditation number, and the date and result of each stage. This is the standard the HSE consultation is designed to make universal — we already apply it on every licensed job.
What This Means for Homeowners Commissioning Removal
Ask for proof of analyst independence
When a contractor quotes for licensed asbestos removal, ask specifically who will carry out the four-stage clearance. The analyst must be a separate company from the removal contractor — not a sister company, not an in-house team. Ask for the analyst's UKAS accreditation number and verify it at ukas.com.
Check the clearance certificate before reoccupying
The clearance certificate must be issued by the independent analyst before the area is reoccupied. It should show the analyst's name, UKAS accreditation number, the date of clearance, the fibre concentration result, and a statement that the area is safe to reoccupy. A certificate that does not include these details is not a valid four-stage clearance.
Retain the certificate permanently
The four-stage clearance certificate is a permanent record that licensed removal was carried out correctly. It should be kept for the life of the building and provided to future buyers, tenants, or insurers on request. It is the primary evidence that the area was safe to reoccupy after removal.
Understand what the consultation means for contractors
Contractors who currently use in-house analysts or associated companies for clearance are operating in a grey area that the HSE consultation is designed to close. Once the consultation response is published, the independence requirement is expected to be tightened. Choosing a contractor who already uses a genuinely independent UKAS-accredited analyst protects you now and in the future.

Frequently Asked Questions
What was the HSE CAR 2012 consultation about?
The HSE ran a consultation between November 2025 and 9 January 2026 on improving the application of the Control of Asbestos Regulations 2012. The main focus areas were the independence of four-stage clearance analysts from removal contractors, UKAS accreditation requirements, NNLW notification thresholds, and training standards.
What is the four-stage clearance procedure?
The four-stage clearance procedure is the process required under CAR 2012 Regulation 22 before a licensed asbestos enclosure can be dismantled and the area reoccupied. It consists of: (1) visual inspection, (2) background air sample, (3) enclosure integrity check, and (4) final air sample. All four stages must be carried out by an independent analyst — not the removal contractor.
Why does analyst independence matter?
If the analyst who issues the clearance certificate is employed by or associated with the removal contractor, there is a conflict of interest. The analyst's commercial relationship with the contractor may influence whether a clearance is passed or failed. An independent analyst has no financial interest in the outcome and is accountable only to the regulatory standard.
What is UKAS accreditation for asbestos analysts?
UKAS (United Kingdom Accreditation Service) accreditation for asbestos air testing means the analyst's laboratory methods have been independently assessed against ISO 17025, the international standard for testing and calibration laboratories. UKAS-accredited analysts are listed at ukas.com. The HSE consultation explored whether UKAS accreditation should become mandatory rather than recommended.
Does this affect domestic asbestos removal?
Yes. The four-stage clearance independence requirement applies to all licensed asbestos work, including domestic garage removal, roof removal, and any other licensed work in a home. Homeowners commissioning licensed removal should ask their contractor who will carry out the clearance and verify that the analyst is independent and UKAS-accredited.
When will the HSE publish its consultation response?
The HSE consultation closed on 9 January 2026. The response and any proposed regulatory changes have not yet been published as of June 2026. We will update this page when the response is released. In the meantime, the existing CAR 2012 independence requirement remains in force.
