The Department for Business, Energy & Industrial Strategy has published guidance for domestic and non-domestic landlords to assist in complying with the 2018 minimum energy efficiency standard, energy performance certificate band E. 

This gives landlords guidance on which properties will be covered and how to deal with energy efficiency improvements for properties. 

From April 2018 all landlords of domestic or non-domestic property will have to ensure that their properties have an EPC rating of at least E before granting any new leases/tenancies. Existing tenancies and leases will also have to comply from 1 April 2020 for domestic properties and 1 April 2023 for non-domestic properties.
