GN21-21 Non-domestic buildings : EPCs and MEES

Most non-domestic buildings which have been built, let, or sold since 1 October 2008 require an Energy Performance Certificate (EPC).

In 2015, the Minimum Energy Efficiency Standards (MEES) were introduced, which require most non-domestic buildings to have a minimum EPC rating of band E when let out on a new tenancy from 1 April 2018, extending to existing tenancies from 1 April 2023.

This guidance note provides an overview of EPCs and MEES for non-domestic properties, including when a property needs to comply and exemptions. For further information, the government guidance can be found here.
