In this comprehensive guide, we break down everything you need to know about spray foam insulation removal in the UK, including real-world costs, mortgage problems, legal standards, and expert advice for homeowners.
Why Spray Foam Insulation Removal Has Become Essential
Spray foam insulation was once marketed as the ultimate energy-saving upgrade. However, by , it’s become a growing headache for property owners across England, Scotland, and Wales. According to the Royal Institution of Chartered Surveyors (RICS), improper installation and lack of regulation have led to many homes being flagged as high risk by lenders and insurers.
Did you know?
- Over 30% of mortgage applications involving spray foam insulation have faced delays or outright refusals in the past year.
- Some major insurers now decline building policies if spray foam is present, regardless of the installation date.
These issues have driven a surge in demand for professional spray foam removal services across the UK.
The Impact of Spray Foam Insulation on Mortgages and Property Value
How Spray Foam Causes Mortgage Problems
Mortgage lenders are increasingly wary of properties containing spray foam insulation, particularly in roof spaces. Surveys often reveal concerns about damp, condensation, or hidden timber damage beneath the foam. As a result, many lenders now require full removal of spray foam before approving a mortgage or remortgage.
Key points:
- RICS surveyors frequently report that spray foam can reduce a property's valuation, sometimes by as much as 20%.
- Properties with spray foam insulation are often deemed "unmortgageable" until removal is completed and attested by a certified contractor.
Insurance and Resale Challenges
Insurance providers are following suit, with some refusing to offer or renew buildings insurance on affected homes. This trend is especially pronounced for older installations or where documentation is incomplete.
Resale prospects are also negatively impacted. Even if your spray foam insulation was installed professionally, public and industry perception can make it harder to sell your home—especially if buyers require a mortgage or insurance.
