Frequently Asked Questions

Find answers to common questions about spray foam removal, EBR-01 compliance, mortgages, and more.

Can spray foam insulation stop me getting a mortgage and how do I fix it?

Yes — most major UK mortgage lenders including Halifax, Nationwide, Santander, NatWest and Barclays decline to lend on properties with spray foam insulation in the roof space, because it can trap moisture and mask timber decay. The fix is professional removal by an EBR-01 certified contractor who issues a compliance documentation pack that surveyors and lenders accept to restore mortgage eligibility.

Affected lenders
Halifax, Nationwide, Santander, NatWest, Barclays, HSBC, Virgin Money, TSB and many building societies.
Why lenders refuse
Foam can hide timber rot and prevent surveyors inspecting the roof structure.
The fix
Removal by an EBR-01 certified contractor with a lender-accepted compliance pack.
Cost range
Typically £1,500–£6,000 depending on property size and whether foam is open or closed cell.
