What EPCs are
An Energy Performance Certificate (EPC) shows:
- how energy efficient a property is and how you can improve it
- how a property affects the climate
There are different EPCs for:
- domestic properties
- non-domestic properties
For domestic properties, an EPC shows the property's:
- 'energy efficiency rating' and typical energy costs (but costs will vary with how each person uses energy)
- 'environmental impact rating' – how much the building affects the climate with CO2 emissions
For non-domestic properties, an EPC shows the property's:
- 'energy performance rating' – how much the building affects the environment with CO2 emissions
EPC ratings
EPC ratings go from A to G – with A as the best.
A property with an 'A' rating is more energy efficient than one with a 'G' rating.
EPCs also give a 'potential' rating. This is the rate the property could be if you make suggested improvements.
Recommendations Report
A 'Recommendations Report' comes with an EPC.
This gives:
- more detailed information on the energy efficiency and climate impact of your property
- how to improve it
- possible cost of improvements
How long an EPC is valid for
An EPC is valid for for up to 10 years. If you get a new EPC before your current EPC expires, the new EPC replaces any older EPCs for your property.
Selling or renting a property
You must get an EPC when you sell a property or rent it to a new tenant.
EPCs also form part of a Home Report.
If you make changes to a property you should update the EPC as it could affect its rating.
