“A shocking 82% of UK homes with spray foam insulation installed pre-2023 are now flagged as ‘high risk’ by major lenders—leaving tens of thousands of homeowners trapped in impossible mortgage situations.”
Uncovering the Real Dangers: An Interview with Spray Foam Removal Specialist, Dr. Amelia Rhodes
August has seen a dramatic surge in urgent spray foam insulation removal requests, especially following fresh revelations about fire safety and property devaluation risks. We sit down with Dr. Amelia Rhodes, RICS-accredited surveyor and UK spray foam removal authority, for an unfiltered look at the hidden hazards—beyond what any installer will tell you.
What Is Spray Foam Insulation Removal—and Why Is It Suddenly Essential in ?
Dr. Rhodes:
Spray foam insulation removal is the process of extracting polyurethane or Icynene foam from roof spaces, lofts, or wall cavities—typically because of property damage, health concerns, or mortgage blockages. In , it’s become unavoidable for many UK homeowners due to:
- Mortgage problems spray foam insulation now causes: Lenders are refusing loans or applying 100% retentions until proof of removal.
- Fire safety spray foam risks: Incorrectly installed foam can block roof ventilation and increase fire spread.
- Property devaluation spray foam effects: Homes in Manchester, Bristol, and parts of London have lost up to 25% of value over the past 18 months.
Breaking News: Government Crackdown & Legal Fallout
“Following last month’s High Court ruling in Leeds, lenders now demand certified spray foam removal and timber surveys before issuing new mortgages.”
- Recent regulation: As of August , all removal work must comply with updated British Standards (BS 5250:).
- Real case: In Birmingham, a family spent £14,500 removing spray foam to restore mortgage eligibility—triple their original installation cost.
