Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what assessment they have made of the (1) value for money, and (2) environmental impact, of providing grants to householders to install types of air conditioning which are environmentally friendly.

The Warm Homes Plan will reduce energy bills and transform homes to be comfortable and low carbon by accelerating the installation of new technologies like heat pumps. The department is also conducting research to ensure homes are resilient to the future climate by identifying the buildings most vulnerable to extreme heat. This research is informing the adaptation solutions in the Warm Homes Plan which will publish in October.

The department recently consulted on expanding the scope of the Boiler Upgrade Scheme to allow air-to-air heat pumps to receive grant funding. The Government Response will be published in due course. Advantages of air-to-air heat pumps include the ability to provide cooling, dehumidification, and air filtration in addition to space heating.
