We measure the sprayed area at the survey, and the quote says which type of foam you have. ## What do other UK sources say? SourceRange Checkatrade (2026)£50 to £75 per m² for open-cell; £80 to £100+ for closed-cell House of Commons Library, briefing CBP-10658 (updated July 2026)about £3,200 for the roof of a three-bedroom detached house, or about £40 per m² MyJobQuote (2026)about £40 per m² on average Spray Foam Helpline (2026)about £40 to £75 per m², or about £3,000 to £7,500 for a typical three-bed loft ## Open-cell or closed-cell? Open-cell foam is soft and spongy. It cuts away from the rafters fairly easily, which is why it costs less to remove. Closed-cell foam sets hard and bonds tightly to the timber. It takes much longer to strip, and the rafters need more cleaning afterwards, so it costs more. If you are not sure which you have, we can tell at the survey. ## A worked example Removing foam from a 50 m² roof: - Open-cell: 50 × £45 = £2,250 - Closed-cell: 50 × £85 = £4,250 If you then want standard loft insulation fitted, 300mm of mineral wool across a 40 m² loft floor is 40 × £30 = £1,200. ## What pushes the price up? The type of foam makes the biggest difference: closed-cell costs almost twice as much to remove as open-cell at our rates. The area matters next. Foam sprayed across the whole roof, or on walls as well as rafters, means more square metres. Access can slow the job down. Low headroom, small hatches and stored belongings all add time. Refitting insulation afterwards is a separate cost, from £10 per m² for mineral wool. ## How removal works We survey the roof, measure the sprayed area and check the foam type. On the day, we protect the house below the loft, cut the foam away from the rafters, clean the timbers, bag the waste and take it away. We can then fit standard loft insulation so the house is not left cold. ## How to compare quotes Ask every firm: - How many square metres are included? - Is the price for open-cell or closed-cell foam? - Is waste removal included? - Is new insulation included, or extra? - Is VAT included?
