Asbestos Removal Calculator

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.

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.

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.

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.

Removing textured coating (Artex) or thermoplastic/vinyl floor tiles is non-licensed work when the material is in good condition and removed without breaking it up. It becomes notifiable non-licensed work (NNLW) when the risk of fibre release is greater — for example large-scale removal of textured coatings using steam or gelling methods, or removal that causes significant break-up and dust. NNLW must be notified to HSE online before work starts (there is no minimum notice period), the work area must be designated and marked, and operatives need medical surveillance with records kept for 40 years.

They are indicative planning estimates, not standardised figures. There is no single authoritative HSE or British Standard weight per square metre, or labour rate, for asbestos materials. The waste weight uses an industry rule of thumb of around 15 kg/m² for asbestos cement (documented surface weights range from about 10.5 kg/m² for thin flat sheet to about 15 kg/m² for corrugated Big Six/Profile 6). Thinner materials weigh much less — thermoplastic/vinyl-asbestos floor tiles are only about 2.4-4.9 kg/m² (1/8 to 1/4 inch thick), so the calculator uses about 5 kg/m² to allow for residual bitumen bedding. Always confirm the actual waste tonnage at the disposal facility's weighbridge and the labour against your contractor's method statement and quotation.

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.
