Question

To ask the Minister for the Cabinet Office, what the Building Research Establishment Environmental Assessment Method (BREEAM) ratings are for 10 Downing Street, 11 Downing Street, and Admiralty House; and whether any assessments have been carried out since July 2024 to determine whether tenancies are in buildings with a BREEAM rating of A or above.

Answer

The Government Property Agency (GPA) uses BREEAM when retrofitting and building new capital projects as per the government buying standards requirements. Where budget and time allows, GPA aims to deliver to the government buying standards requirements or better. As these buildings are not being developed the BREEAM standard is not relevant. If the buildings were to be retrofitted by the GPA in the future, BREEAM would be applied as per the government buying standards requirements.

In regards to existing commercial spaces, the GPA will deliver to the MEES (Minimum Energy Efficiency Standards, regulations) and produce Display Energy Certificates (DECs) and/or Energy Performance Certificates (EPCs) where commercially relevant.
