Energy efficiency (EPC)

Energy efficiency (EPC)

The dashboard below shows EPC (Energy Performance Certificate) data for residential properties in Southampton. EPCs rate the current and potential energy efficiency of a home out of 100 (these ratings are also grouped A to G). Energy efficient properties are deemed to be those with a current rating of C or better. This dashboard shows how the percent of energy efficient homes varies across the city.

Not every residential building has a current EPC rating as they have only been mandatory since 2008, around 1 in every 3 homes in Southampton does not have an EPC and is therefore not included in the dashboard.

Up-to-date national trends and more information on EPCs is available on the Office for National Statistics' page on energy efficiency.
