The government has published a comprehensive guidance document for non-domestic landlords subject to the upcoming Minimum Energy Efficiency Standards (MEES), outlining a number of government rules including a seven year payback test to determine possible exemptions from the regulations.

From 1 April 2018, commercial properties will not be able to sign new tenancy agreements unless they reach a minimum EPC rating of E. It has been estimated these rules will affect a fifth of non-domestic buildings falling under the scope of MEES but until now, little guidance has been available in preparation for the rules.

Just over a year ahead of their introduction, the Department of Business, Energy and Industrial Strategy (BEIS) has explained how the regulations will be implemented, including details of a number of exemptions.

MEES require landlords of properties rated at EPC F or G to improve the property to at least an E, or register an exemption should one apply, when the tenancy is being renewed or extended, or a new tenancy is being granted.
