Quick answer: CAR 2012 requires a Refurbishment and Demolition Survey before any construction or maintenance work begins in a pre-2000 building where ACMs may be disturbed. There are three work categories: licensed (asbestos insulation and AIB, HSE-licensed contractor required), notifiable non-licensed (asbestos cement, textured coatings — notification required), and non-licensed (lower-risk incidental work). H-Class extraction (H14 HEPA, 99.995%) is mandatory for all vacuum work involving asbestos dust across all three categories — M-Class is not permitted. Filter changes are asbestos waste events requiring sealed disposal.
Asbestos is present in a very high proportion of UK buildings constructed before 2000. For construction and maintenance contractors, CAR 2012 is not an optional compliance consideration — it is the mandatory legal framework for any work that may disturb asbestos-containing materials (ACMs). The obligation begins before a single tool is picked up and applies regardless of whether the contractor considers the work minor or routine.
The most common failure modes for contractors working in pre-2000 buildings:
- Starting maintenance or refurbishment works without commissioning a Refurbishment and Demolition Survey
- Assuming that the absence of known asbestos means it is not present
- Using M-Class extraction or standard vacuums for ACM-contaminated material — only H-Class is permitted
- Failing to register work under notifiable non-licensed (NNLW) requirements where notification is required
- Not following sealed disposal procedures for H-Class filter changes — filter changes on ACM work are asbestos waste events
- Working without a suitable written plan of work for licensed asbestos work
The three categories of asbestos work under CAR 2012:
Licensed work — asbestos insulation, asbestos insulating board (AIB), asbestos lagging. Only HSE-licensed asbestos contractors may carry out this work. Notification to HSE required. Medical surveillance required. Written plan of work. H-Class extraction and full RPE mandatory.
Notifiable non-licensed work (NNLW) — asbestos cement, textured coatings (Artex), asbestos floor tiles in good condition. Non-licensed contractors may carry out this work but must notify the relevant enforcing authority before starting. Health records and H-Class extraction required.
Non-licensed work — lower-risk incidental contact with asbestos in good condition. Still requires a risk assessment and appropriate controls. H-Class extraction still required for any vacuum work involving ACM debris.
H-Class extraction (H14 HEPA, 99.995%) is mandatory across all three categories for any vacuum operation involving asbestos dust or ACM debris. M-Class vacuums are not permitted for asbestos work — asbestos fibres pass through M-Class filtration. Sealed Type H disposal bags are required — removing an M-Class or standard bag from a vacuum used on asbestos creates a secondary release event. Under COSHH Regulations 2002, asbestos is a substance hazardous to health and the control hierarchy must be applied rigorously. Under CDM 2015, principal contractors have duties to manage asbestos risk across the site.
