The questions we are asked most
- 1Why is spray foam in a loft a problem?It can trap moisture against the roof timbers and hides them from surveyors, so lenders and buyers often ask questions. Read the answer
- 2Can I get a mortgage on a house with spray foam?Often, yes. In October 2026 the government named eight major lenders as open to lending, subject to their own checks. Read the answer
- 3Do I have to remove it?Not always. It depends on the foam, the roof and what your lender or buyer asks for. Get any requirement in writing first. Read the answer
- 4How much does removal cost?Typically £50–£80 per m², which is £3,000–£8,500 for most UK lofts. Read the answer
- 5Can I make a claim against the installer?Possibly, through the installer, the guarantee or an ombudsman. Which route applies depends on when it was fitted. Read the answer
- 6Is there a government grant for removal?No. The government's October 2026 paper sets out no grant or funding for removal. Read the answer
On 22 October 2026 the Department for Energy Security and Net Zero published Spray foam insulation: Remediation, removal and lending. It says many mortgage providers are open to lending on homes with spray foam, subject to their own requirements, and that removing foam "will not always guarantee" a lender will still lend.
It tells homeowners to take advice from a specialist surveyor before deciding anything. It says nothing about grants or funding for removal.

Does spray foam always have to be removed?
No. It depends on the property, the foam, its condition and the requirements of the lender, buyer or surveyor involved. Ask for any removal requirement in writing before booking work.
Will spray foam removal guarantee a mortgage?
No. No company can guarantee a lender decision. Removal and supporting evidence may help, but each lender and valuer applies its own requirements.
Which mortgage lenders accept spray foamHow is the type of spray foam identified?
A removal specialist can review installation documents and photographs, or inspect the roof space, before recommending the work. Open-cell and closed-cell foam are removed differently, which affects both method and cost.
How to tell if you have spray foamWhat is a spray foam removal certificate?
It is part of the evidence showing what was inspected or removed, usually with photographs and a description of the work. The exact paperwork needed depends on the lender, buyer or surveyor reviewing the property.
Spray foam removal certificates explainedCan I remove spray foam myself?
DIY removal is strongly discouraged. It risks exposure to dust and chemicals, damage to timbers or wiring, incomplete removal and mistakes with waste disposal, and it leaves no paper trail for a lender. Use a professional specialist.
Can I remove spray foam myself?How long does spray foam removal take?
Most three-bedroom homes take 2–5 days once work starts. Roof complexity, foam type, access and waste disposal all affect the timeline, and your quote should set out the expected programme.
