How much does spray foam removal cost in the UK? (Quick answer)
Last updated: May 2026 · Compiled by Spray Foam Removal Advice from published cost data and quotes received through this service
Professional spray foam removal in the UK costs £50-80 per m², which comes to £5,000-£8,000 for a standard 100m² loft. Across the range of UK property sizes, most homeowners pay £3,000-£8,500 in total. Open-cell foam sits at the lower end of that per-metre rate because it's softer and faster to strip; closed-cell is denser, bonds harder to the timber, and sits at the top.
That figure normally includes labour, PPE, waste removal and a written removal report. It does not usually include any timber repairs (£200-£1,000+), re-insulation (£300-£1,500+), or a separate RICS/insulation certificate where a mortgage lender requires one.
It's worth getting three quotes from certified contractors any time the variance between site visits is likely to be material — i.e. when access is awkward, the foam is closed-cell, or the property is being remortgaged or sold.
A standard £3,000-£8,500 removal protects against the £10,000-£30,000 cost of full roof replacement if foam-related rot is left to progress.
