According to a report in the Daily Telegraph, individuals are increasingly falling prey to door-to-door salespeople offering exclusive, time-limited offers on cost-effective insulation solutions.

Certain companies are charging substantial sums for spray foam installations, often failing to apply it correctly, resulting in moisture-related issues in roofs. This is occurring despite the introduction of a new industry code of practice.

Property assessors frequently advise the removal of such insulation prior to a property's sale, as potential buyers may encounter difficulties securing a mortgage unless the polyurethane foam is removed.

Last year, Nationwide issued a warning about a surge in cases of homeowners facing problems stemming from this type of insulation. It was linked to approximately 250,000 properties becoming ineligible for mortgages.

The lender highlighted that individuals are increasingly susceptible to dishonest installers as they strive to enhance their homes' energy efficiency and reduce costs.

The Insulation Manufacturers Association (IMA), which includes makers and installers, surveyors, valuers and lenders, published a code of practice on spray foam installation in May.

Independent surveyors trade body RPSA (Residential Property Surveyors Association) performed a U-turn last year on its guidance for spray foam installation.

The RPSA retracted the guidance, which said that if no detailed technical information was available then surveyors should recommend the foam is removed and the roof replaced.
