Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate she has made of the number of homes whose sales have been affected by a lack of access to financial products due to spray foam insulation.

The pricing and availability of mortgages, including decisions on the type of property to lend against spray foam, is a commercial decision for lenders in which the Government does not intervene. Therefore, we do not hold a record of these numbers.

The department has recently published guidance on GOV.UK (Spray foam insulation: Remediation, Removal and Lending), which provides consumers with information and links to consumer support on spray foam. This also includes a list of lenders who are open to lending on properties with spray foam, subject to their own requirements. For more information:
