Question

To ask the hon. Member for Blaenau Gwent and Rhymney, representing the House of Commons Commission, if the Commission will list the energy performance certificate ratings recorded for each building within the Parliamentary estate in each of the last five years.

The House of Commons retains copies of Energy Performance Certificates (EPC) where we acquire new buildings or undertake major refurbishments. It also holds EPCs for buildings or spaces that we lease. These EPCs are the responsibility of our landlords.

The buildings and EPC ratings for buildings in these categories are detailed in the table below. Data for Derby Gate is not available for the period of refurbishment running to 2022. We do not currently hold the data for 14 Tothill Street for 2021–22

The areas of the Parliamentary Estate used by the House of Commons includes a number of freehold buildings that have not been subject to major refurbishment and where EPCs are not therefore required. The House of Commons also holds several properties in Bridge Street which are rented out for non-Parliamentary uses.

We also hold Display Energy Certificates (DECs) for several buildings across the Parliamentary Estate. DECs are designed to show the energy performance of public buildings. As part of our commitment to sustainability and compliance, we commission annual DECs for many of our buildings. These certificates are publicly accessible via the Find an energy certificate service on GOV.UK. DECs are also displayed at the Palace of Westminster and Portcullis House.

Pages 39–46 of the House of Commons Administration Annual Report and Accounts 2024–25 provide an Environmental Review detailing the steps the Administration is taking to increase sustainability as well as data on emissions and energy consumption for the Estate (House of Commons: Annual Report & Accounts 2024-25).
