England and Wales
Since 1 April 2018, it is illegal to let out any residential property in England and Wales with an EPC rating of band F or G (the least efficient bands).
Since 1 April 2020, it is illegal to continue letting out residential property that doesn't have an EPC rating of band E or higher. This means that from 1 April 2020 all residential property let out to tenants must have an EPC rating of band E or higher, even if the tenancy started before this date. The required ratings are subject to exemptions.
For commercial property, when a new tenancy is created the property must currently have an EPC rating of band E or higher. From 1 April 2023, this minimum will apply to all commercial tenancies, new and existing. The minimum will continue to rise gradually until, by 1 April 2030, properties will need to have a minimum EPC rating of band B. For more information, read the Government’s guidance.
The band E standard required in Scotland was removed due to challenges facing the residential private rented sector during the Coronavirus (COVID-19) pandemic. Amended plans require that properties have a band C rating as a minimum by 2025, where this is technically feasible and cost-effective. The requirement will apply regardless of technical feasibility and cost-effectiveness from 2028.
In Scotland, the EPC must be displayed somewhere within the property (eg in the meter cupboard or next to the boiler).
