Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what steps his Department is taking to ensure that programmes to retrofit homes to make them more energy efficient protect against extreme heat as well as cold.

The Government has started delivery of the Warm Homes Plan, including a new Warm Homes: Local Grant, and the Warm Homes: Social Housing Fund. These schemes require installers to be Trustmark registered and measures to be installed in accordance with the Publicly Available Specification (PAS) 2030 and PAS 2035. This ensures the risks of unintended consequences, such as mould, condensation due to poor ventilation and overheating, are minimised.

The Warm Homes Plan will ensure that homes are fit for the future. To support policy development in this area, the Government is conducting research to identify which building types are most vulnerable to extreme heat and appropriate adaptation solutions.
