Energy Performance Certification tests energy efficiency and environmental impact of buildings. Who needs an EPC?
- There are no residential properties that do not require certification for energy efficiency. Selling or renting a home without an EPC is unlawful.
- If your property is newly built, you need an EPC by conducting SAP calculations. These calculations ensure compliance with Part L of the Building Regulations.
- When you upgrade or expand your property you’ll need an updated EPC, even if it already has one.
- Residential properties need a revised EPC every ten years. Nevertheless, if the building facilities, such as a newly installed heating system, are significantly changed, it may need to be earlier.
- As of 1 April 2018, issuing a new lease or renewing an existing lease on homes with an F or G energy rating will be unlawful.
- Beginning 1 April 2020, this will apply to all private rented residential properties, whether it is a new lease or not.
- Places of worship.
- Less than 50m2 stand-alone non-dwellings.
- Industrial areas, workshops and low-energy non-residential farm buildings.
- Temporary buildings with 2 years or less expected use time.
- Non-residential agricultural buildings used by a company protected by a National Sectoral Agreement on Energy Performance Certification.
- Please note that leasing non-domestic properties with low energy performance ratings will be unlawful as of 1 April 2023.
