Energy Performance of Buildings

Access to Energy Performance Certificates and Display Energy Certificates data for buildings in England and Wales. Searchable, browsable and downloadable individually or in bulk from MHCLG.

Find an energy certificate for a property in England, Wales or Northern Ireland. This includes homes, business properties and public buildings.

Median energy efficiency score of dwellings in England and Wales, by property type, tenure, property age and whether new or existing. Published by the Office for National Statistics. Updated annually in October

The Office for National Statistics (ONS) produced this data visualisation tool to show the energy efficiency of dwellings in an area. It shows maps for all dwellings, existing houses and flats and new houses and flats. The visualisation is included in an article by the ONS about the energy efficiency of housing in England and Wales in 2022. ONS base findings in the article on analysis of EPC open data from the Department for Levelling Up, Housing and Communities Open Data Communities website.

The Office for National Statistics (ONS) has published this data visualisation map which shows the energy efficiency of homes in an area. It shows the number and proportion of homes in area with an EPC rating of C or above, and the proportion in the local authority built before 1900, or built in 2012 or later. The visualisation is included in an article by the ONS which show the age of a property is the most significant factor associated with energy efficiency, ahead of fuel type and property type. ONS base these findings on analysis of EPC open data from the Department for Levelling Up, Housing and Communities Open Data Communities website.

Tables showing data from certificates lodged on the Energy Performance of Buildings Registers since 2008.

There is also an interactive dashboard to explore on this site which presents quarterly statistics on Energy Performance Certificates issued for domestic and non-domestic buildings.

ODI Leeds exploration project looking at EPCs and housing retrofit potential.

EPC certificates represent a fantastic resource, helping to better understand the energy efficiency of buildings and how they can be improved. EPCs contain data on indicators which detail the current and potential performance that each building can achieve. The difference between these two values can be considered as the buildings capacity for improvement. in 2018 ODI Leeds used hex maps to represent this data at ward level to visualise areas within Calderdale that would benefit the most from improvements.
