Beginning 1 April 2018, under the Energy Efficiency (Private Rented Property) (England and Wales) Regulations 2015 (commonly referred to as the MEES Regulations), non-domestic landlords must ensure that any properties they rent out in England and Wales have an energy efficient rating of at least an E (using the A-G rating system from Energy Performance Certificates (EPCs)). This requirement will apply on the grant of a tenancy to new tenants, or a renewal with existing tenants after that date.  These requirements will extend to all such properties, even where there has been no change in the tenancy arrangements, from April 2023.

The UK government has recently issued Guidance for landlords on how the MEES Regulations are expected to operate and the implications for landlords who do not meet the requirements.
