Energy Performance Certificates: guide
Energy performance certificates (EPCs) explain how energy efficient a building is and how it could be improved.
About Energy Performance Certificates (EPCs)
An EPC provides information about how energy efficient a building is, and how the efficiency could be improved. Buildings are rated on a scale from A to G, with A being the most efficient.
The EPC also provides:
-
information on measures which could be made to improve the energy efficiency of the building
-
an indicative cost for each improvement
The EPC is accompanied by a recommendations report which provides more detailed information about improvement measures.
The EPC assessment reflects the energy performance of the building itself, not the way it is used by its occupants. This means that standard assumptions are made about occupancy and use, so that different buildings can be fairly compared. The EPC does not contain personal information, other than the name and contact details of the assessor who carried it out.
For non-domestic buildings, the EPC shows an asset rating, alongside an indication of energy performance based on primary energy use.
We're reforming EPCs in Scotland. The Energy Performance of Buildings (Scotland) Regulations 2025 will bring new-style certificates with more detailed ratings and strengthened quality assurance. You can find out more at: EPCs are changing.
