The Energy Efficiency Rating

The energy efficiency rating will be displayed on an A to G scale. The least efficient buildings will be rated G and the most efficient will be rated A.

As well as a current rating for the property, a potential rating will also be shown, which is the energy efficiency rating after all recommendations have been applied to the property.

For England, Wales and Northern Ireland the current EPC rating will be shown at the top of the EPC.

The rating is actually based on cost factors such as the type of fuel used for heating, hot water, lighting and ventilation.

Currently if the property uses main gas it will score higher on the energy efficiency rating than a property which uses electricity. This is due to mains gas being cheaper per p/kWh than electricity.
