Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what recent estimate she has made with Cabinet colleagues of the potential cost of upgrading all homes in England to at least energy performance certificate rating C.

The Government set out an aspiration in the Clean Growth Strategy for as many homes as possible to reach an Energy Performance Rating Band C by 2035 where cost-effective, affordable and practical. Achieving this will require mobilising up to £65 billion of capital investment.

The Government is investing £6.6 billion over this Parliament on clean heat and improving energy efficiency in buildings. In addition, £6 billion of new Government funding will be made available from 2025 to 2028.
