Number of records added to register for new homes energy efficiency rating, 2009 to 2020, England and Wales — Energy efficiency of domestic buildings
There were 89% of new buildings allocated to A or B energy efficiency rating in 2020.
New dwellings cover new builds as well as conversions and change of use of existing properties (i.e. converting a house into self-contained flats or changing a church into a dwelling). Energy Performance Certificates gives homes a rating from A being the most efficient to G being the least efficient.
The energy efficiency rating is a measure of the overall efficiency of a building. This rating is based on the performance of the building and its fixed services (such as heating and lighting). The higher the rating the more energy efficient the home is and the lower the fuel bills will be.
