Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what estimate he has made of the proportion of houses in the UK which are sufficiently insulated; and what steps he will take to install adequate insulation in houses that do not have it.

The Government set an aspiration in the Clean Growth Strategy for as many homes as possible to reach at least EPC Band C by 2035, where cost-effective, affordable, and practical.

The UK has made good progress in improving the energy performance of homes. Over 40% of homes in England now have an EPC of C or better, up from 12% in 2009. The Government has committed to spend £3.8 billion in this Parliament to improve the energy performance of homes, including through insulation.
