Spray Foam Insulation Removal: The UK Investigation No One Is Talking About
Updated August – This is the definitive guide to spray foam insulation removal, legal requirements, and the hidden property risks facing UK homeowners.
The Shocking Truth: 72% of UK Spray Foam Installations Now Under Scrutiny
In a bombshell report released this summer, the Property Care Association (PCA) revealed that over 72% of spray foam insulation installations in UK homes since 2018 may be non-compliant with current industry and lender standards.
Mortgage refusals, plummeting property values, and urgent removal orders have left thousands of homeowners in limbo.
But how did things get so bad? And what can you do right now if your home is affected?
Breaking: Birmingham Couple Faces £18,000 Bill After Foam Installation Blocks Home Sale
Consider the case of Julie and Mark Evans from Edgbaston, Birmingham:
After installing open-cell spray foam insulation in 2021 (on the promise of "energy savings and higher property value"), their home failed a RICS survey in May . All four major lenders refused a mortgage on the property until the foam was removed and a compliance certificate issued.
Their removal quote? £18,000 – plus £2,500 for roof repairs.
Their story is far from unique.
