When do I need a licensed asbestos removal contractor?

Licensed contractors are required under the Control of Asbestos Regulations 2012 for work with asbestos insulating board (AIB), pipe lagging, sprayed coatings, and any work where the fibre release is not sporadic and of low intensity. The HSE maintains a public register of licensed contractors. An ASB5 notification must be submitted to the HSE at least 14 days before licensed work begins.

What is the difference between encapsulation and removal?

Removal physically takes out the asbestos-containing material and disposes of it at a licensed hazardous waste facility. Encapsulation coats the material with a sealant that binds the fibres and prevents release. Encapsulation is cheaper and less disruptive but is only suitable for materials in good condition that will not be disturbed. It does not remove the long-term liability of having asbestos in the building.

How much does asbestos disposal cost in the UK?

Asbestos disposal at a licensed hazardous waste landfill typically costs £150-£300 per tonne, significantly more than general construction waste. Double-wrapped asbestos waste bags must be transported by a licensed carrier to a facility with a hazardous waste permit. A consignment note is required for each load under the Hazardous Waste Regulations.

Can I remove asbestos cement sheets myself?

Homeowners can legally remove small quantities of low-risk asbestos cement (e.g. garage roofing sheets) provided they follow HSE guidance (HSG210). This involves wetting the material, not breaking it, wearing RPE (FFP3 minimum), double-bagging waste, and disposing at a council household waste site that accepts asbestos. However, hiring a professional is strongly recommended for safety.

What PPE is required for asbestos work?

Minimum PPE includes an FFP3 disposable respirator (or full-face powered respirator for licensed work), disposable Type 5/6 coveralls with hood, disposable gloves (doubled), and wellington boots. All PPE must be treated as contaminated and disposed of as asbestos waste. A full decontamination procedure is required after each work session.

How We Calculate This

This calculator classifies asbestos-containing materials by risk level per the Control of Asbestos Regulations 2012 and estimates removal or encapsulation requirements.

Risk classification

Non-licensed work: Low-risk materials like cement sheets and floor tiles where the material is in good condition and will not be significantly broken up.

Notifiable non-licensed work: Some lower-risk work that must be notified to the enforcing authority, such as textured coating removal and gasket replacement.

Licensed work: High-risk materials including insulating board, pipe lagging, and sprayed coatings. Requires HSE-licensed contractors, ASB5 notification (14 days), and full containment with negative pressure enclosures.

Disposal requirements

All asbestos waste must be double-wrapped in UN-approved asbestos waste bags (red with asbestos warning), transported by a licensed carrier with consignment notes, and disposed of at a hazardous waste landfill with the appropriate permit.
