Under new regulations for commercial landlords, properties that require an Energy Performance Certificate (EPC) must obtain a minimum efficiency rating of an E before they can be let.
An EPC provides information on how energy efficient a building is by giving it a rating of A (very efficient) to G (inefficient). This rating system helps tenants to ascertain how much it will cost to heat and light the building, as well as an indication of the level of carbon emissions. The certificate also suggests ways that a more efficient rating could be achieved.
The minimum energy efficiency standards (MEES) come into force in April 2018, from which time landlords cannot grant a new tenancy agreement or renew an agreement if a commercial rented property has an EPC rating of F or G. From April 2023, landlords must not continue to let a commercial property under an existing agreement if it does not meet the minimum energy efficiency criteria. BEIS has issued full guidance on the requirements and possible exemptions under the legislation.
