Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, with reference to the press release entitled Warm homes and cheaper bills as government accelerates Plan for Change, published on 7 February 2025, what estimate he has made of the number and proportion of remaining properties not at energy performance certificate level C that will not be able to be upgraded to that level owing to the nature of the property.

As outlined in the consultation-stage Options Assessment (DESNZ001(OA)-25-NZBI), there are 5.1 million privately rented properties in England and Wales, with 55% below the current EPC C. Under the preferred option, 2.8 million properties could reach the proposed new EPC C standard by 2030. Some properties may remain below standard as the consultation proposed a range of exemptions for those unable to reach EPC C. Government is currently analysing responses to decide on a final policy outcome and will publish a government response and further impact assessment in due course.
