Mortgage Lenders Raise Concerns Over Spray Foam Insulation: What Homeowners Need to Know

As energy efficiency becomes a priority for homeowners, many have turned to spray foam insulation to seal roof spaces, walls, and floors. While its ability to enhance energy efficiency is well-publicized, the material is now under scrutiny by mortgage lenders due to concerns about its impact on property safety, longevity, and resale value.

Why Are Mortgage Lenders Hesitant About Spray Foam?

While spray foam insulation has gained popularity for its ability to reduce heat loss and improve energy efficiency, it's important to be aware of its potential drawbacks. Structural and fire safety concerns are causing hesitation among lenders, highlighting the need for caution when considering this type of insulation.

• Structural Risks: Spray foam can trap moisture in roof timbers, potentially causing wood to rot over time. This compromises the roof's structural integrity, which may result in costly repairs or even complete roof replacement.

• Fire Safety Concerns: Certain types of spray foam can pose fire risks if not properly installed, making lenders and insurers cautious about properties with such insulation.

Lenders' Stance on Properties with Spray Foam

A recent investigation by the BBC revealed that five of the UK's largest mortgage lenders—including TSB Bank, Skipton Building Society, and Aviva—would not approve loans for properties with spray foam in the roof. Others, such as Yorkshire Building Society and Metro Bank, will only lend if the insulation is minimal.

Some lenders, including Lloyds, Nationwide, and Barclays, evaluate such properties on a case-by-case basis, often requiring a surveyor's report to determine the extent of potential risks. Equity release providers like More 2 Life are stringent, lending only if the insulation was installed as part of an authorized new build with proper documentation.

Impact on Homeowners and Buyers

For homeowners, the presence of spray foam insulation could make selling a property more challenging. Property lawyers warn that buyers may need help to secure a mortgage, effectively reducing the pool of interested parties and potentially lowering property value.

What Should Homeowners Do?

If you already have spray foam insulation or are considering installing it, here are a few tips to mitigate issues:

1. Obtain Documentation: Ensure a certified professional installs the insulation and keeps work records, including guarantees and product specifications.

2. Regular Inspections: Schedule periodic inspections to check for moisture retention or timber rot, addressing issues promptly.

3. Consult a Surveyor: Before selling, get a valuation or report from a trusted surveyor to reassure potential buyers and lenders.

4. Communicate with Lenders: If you're looking to remortgage or sell, contact your lender in advance to understand their criteria for properties with spray foam.

Looking Ahead

While spray foam insulation offers energy-saving benefits, the concerns raised by mortgage lenders underscore the importance of thorough research and professional advice before installation. This empowers homeowners to make informed decisions and avoid potential issues in the future.

The rising scrutiny around spray foam insulation serves as a reminder of the delicate balance between energy efficiency and long-term property value. It's a testament to the fact that sustainable upgrades must save energy and enhance safety and marketability, prompting homeowners to be mindful and strategic in their choices.
