What is Spray Foam Affecting House Sale?

Definition and Context

Spray foam insulation is a material applied to roofs and walls to enhance energy efficiency by sealing gaps and preventing heat loss. However, its application has been linked to complications in property sales across the UK.

Recent Statistics (2024-2026)

• As of 2025, 67% of UK properties with spray foam insulation faced mortgage rejections. (sprayfoamremovaladvice.co.uk)

• By 2026, major lenders, including TSB, Nationwide, and Halifax, have implemented policies rejecting properties with spray foam insulation. (sprayfoamremovaladvice.co.uk)

Why It Matters for UK Homeowners

The widespread use of spray foam insulation, particularly under government-backed schemes, has inadvertently led to a significant number of properties becoming unsellable or devalued. Homeowners now face the dilemma of either removing the insulation or accepting a reduced sale price.

Why This Matters for Your Property

Mortgage Implications

Many UK mortgage providers have outright policies against approving loans for properties with spray foam insulation unless:

• A detailed structural survey demonstrates that the roof is free from damage.

• The foam has been professionally installed and certified.

This means that potential buyers may struggle to secure financing, leading to prolonged market listings or the need to lower the asking price. (simmonstaylorhall.co.uk)

RICS Surveyor Guidance

The Royal Institution of Chartered Surveyors (RICS) has updated its guidelines to address properties with spray foam insulation. Surveyors are now advised to assume potential defects in the roof structure if spray foam is present, which can lead to reduced property valuations. (sprayfoamremovaladvice.co.uk)

Property Value Impact

Properties with spray foam insulation have seen a devaluation of £20,000 to £50,000 or more. This significant reduction is due to the combined effects of mortgage rejections, buyer apprehension, and the costs associated with removing the insulation. (nationalsprayfoamadvice.co.uk)

Insurance Considerations

Securing standard buildings insurance becomes challenging for properties with spray foam insulation. Some insurers may refuse coverage, while others might offer it at significantly higher premiums, further deterring potential buyers. (nationalsprayfoamadvice.co.uk)
