Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether he will take steps to provide redress to people whose (a) property values or (b) access to mortgage finance has been impacted by spray foam insulation installed using a Green Homes Grant Voucher.

The Department has worked with the insulation industry and lending community to address concerns relating to spray foam. Protocols were published in March 2023 to support surveyors to assess spray foam, provide reassurance to lenders, and inform consumers.

While the Department cannot comment on the decisions made by individual lenders, the presence of spray foam should not automatically prevent lending. Decisions should be made on a case-by-case basis following a survey. Recent indications are that most mortgage lenders no longer have blanket policies on spray foam insulation.

Any borrower seeking to take out a mortgage may find it useful to shop around and speak to a mortgage broker to find the best possible product for them.
