Spray Foam Insulation Removal: The Hidden Risks UK Homeowners Can't Ignore in
Updated August – Latest regulations, real UK case studies, and urgent mortgage impact updates.
A Shocking August Story: Spray Foam Nightmare in Manchester
On 3rd August , BBC News North West broke the story: a family in Didsbury saw their £550,000 home devalued by £120,000—overnight—after a RICS surveyor flagged spray foam insulation as a “major mortgage concern.” Their dream sale collapsed. By the end of that week, three more Greater Manchester homeowners faced similar devastation, forced to rip out spray foam—at costs exceeding £9,000—just to keep their homes on the market.
How did this once-trendy upgrade become such a disaster for UK property owners?
Let’s uncover the hidden dangers lurking above your head—and why professional spray foam removal is now one of ’s fastest-growing property services.
What Is Spray Foam Insulation Removal? (Definition)
Spray foam insulation removal is the professional process of safely extracting previously installed spray foam from lofts or roofs, often to address mortgage problems, property devaluation, surveyor red flags, fire safety, or moisture-related timber rot.
Why Are So Many UK Homeowners Removing Spray Foam in ?
1. Surveyor Red Flags: The Mortgage Timebomb
- 76% increase in spray foam “red flag” mentions in RICS residential surveys (–).
- Major UK lenders—including Halifax and NatWest—often reject mortgage applications on properties with unverified spray foam.

“Mortgage lenders are reluctant to lend where spray foam is present, especially if documentation is lacking.”
— RICS Guidance Note, June
2. Timber Rot & Moisture Damage: The Silent Threat
