Quick Answer: Which Lenders Accept Spray Foam?
Very few UK mortgage lenders accept properties with spray foam insulation. Over 50 major lenders including TSB (complete ban), Halifax, Nationwide, and most building societies reject spray foam properties outright or require expensive specialist surveys. Only a handful of specialist lenders may consider it, often with higher rates and strict conditions.
The most reliable solution is professional spray foam removal (£50-80/m²) with a mortgage-compliant certificate, which restores full lender eligibility.

Why Do Mortgage Lenders Reject Spray Foam?
1 Cannot Inspect Roof Timbers
Spray foam covers rafters, making it impossible for surveyors to assess timber condition, rot, or structural damage. Lenders cannot verify the security of their investment.
2 Condensation & Moisture Risks
Improper installation traps moisture, causing hidden rot and structural decay. Lenders view this as unacceptable long-term risk to property value.
3 Resale Difficulties
With most lenders rejecting spray foam, the buyer pool is severely limited. Lenders worry about recovering their investment if repossession is needed.
4 RICS Guidance
The Royal Institution of Chartered Surveyors (RICS) advises caution on spray foam properties. Lenders follow this professional guidance in their policies.
