London has a bigger proportion of energy efficient homes than the rest of England, and Tower Hamlets is the leading borough with 3 times the national average for the top green rating.
Whenever a home is built, sold or let it requires a Domestic Energy Performance Certificate that rates it from A to G for its level of energy efficiency. 11.2% of homes are rated as A or B in London compared to 8.8% for England. For A, B and C ratings London is ahead again – 41% compared to 36%.
Urbs looked at all the certificates on the local authority registers from 2008 to the end of the most recent quarter (Q2 2015). As our borough map reveals there are some wide variations in housing energy efficiency, likely related to the nature of the housing stock.
27% of the homes in Tower Hamlets are in the A/B category compared to just 5% in Kensington and Chelsea. Tower Hamlets includes the Canary Wharf and Limehouse areas that have seen a huge expansion in new build houses and flats that are more energy efficient than older homes.
