From 1 April 2020, all domestic private rental properties must have an Energy Performance Certificate (EPC) rating of at least E. From 1 April 2023 this will apply to non-domestic properties too.
Any property for sale or rent needs an EPC which shows its energy efficiency, typical energy costs and suggestions of how to reduce energy usage. The regulations are intended to ensure that tenants have the best living conditions and lower energy bills.
Landlords must use an approved domestic energy assessor to produce an EPC, if the building doesn't already have one. Some properties are exempt but must be registered on the Private Rented Sector (PRS) exemptions register.
Breaches of the regulation can result in fines of up to £5,000.
