Energy Performance Certification measures a building’s energy efficiency and environmental impact. But who needs an EPC?
- There are no residential properties that do not need energy performance certification. It is against the law to sell or rent a home without an EPC.
- If your property is newly built, you will need to get an EPC by carrying out SAP calculations. These calculations make sure your building complies with Part L of The Building Regulations.
- If you convert or extend your property, you will need to get an updated EPC, even if the property already has one.
- Generally, residential properties need an updated EPC every ten years. However, if there is a major change to the building services, such as a newly installed heating system, this may need to be sooner.
- As of 1st April 2018, it will be against the law to grant a new lease or renew an existing lease on homes with an energy rating of an F or G.
- From 1st April 2020, this will extend to all privately rented residential properties – irrespective of whether it is a new lease or not.
The same EPC requirements govern commercial properties as residential properties. However, there are some exceptions. The following properties do not require an EPC:
- Places of worship.
- Stand-alone non-dwellings of less than 50m2.
- Industrial sites, workshops and non-residential agricultural buildings with low energy demand.
- Temporary buildings with a planned usage time of 2 years or less.
- Non-residential agricultural buildings which are used by a sector covered by a national sectoral agreement on energy performance certification.
*Please note that as of 1st April 2023, it will be against the law to rent non-domestic properties with poor energy performance ratings.*
