New research has revealed the areas of England with the best and worst percentages of energy-efficient homes.
The study by Enviro Homes Renewables looked at the latest data from the Office for National Statistics, which showed the percentage of homes in each local authority that had an Energy Performance Certificate (EPC) of Band ‘C’ or above.
Tower Hamlets in London claims the highest share of energy-efficient homes, with 76.11% of properties achieving an EPC of band ‘C’ or above in 2022. The City of London and Southwark also feature in the top three, with 62.74% and 62.07% of homes respectively meeting this standard.
Other areas with a high proportion of energy-efficient homes include Salford in Greater Manchester (62.04%) and Hackney in London (61.27%).
The top ten England areas with the most energy-efficient homes
| Rank | Local authority district name | Region | Percentage of dwellings with EPC Band ‘C’ or above, 2022 |
| 1 | Tower Hamlets | London | 76.11% |
| 2 | City of London | London | 64.74% |
| 3 | Southwark | London | 62.07% |
| 4 | Salford | North West | 62.04% |
| 5 | Hackney | London | 61.27% |
| 6 | Greenwich | London | 59.41% |
| 7 | Cambridge | East of England | 59.23% |
| 8 | Dartford | South East | 58.81% |
| 9 | Milton Keynes | South East | 58.50% |
| 10 | Islington | London | 58.18% |
The research highlights the significant regional disparities in home energy efficiency across England, with the top 10 worst falling outside of London and the South East.
The Isles of Scilly, located off the Cornish coast, has the lowest proportion of energy-efficient homes in England, with just 14.09% of properties having an EPC of Band ‘C’ or above in 2022. Pendle in Lancashire takes second place with 21.83% of homes meeting this criteria, followed by Castle Point in Essex at 24.84%.

| 2 | Pendle | North West | 21.83% |
| 3 | Castle Point | East of England | 24.84% |

| 10 | Calderdale | Yorkshire and The Humber | 29.46% |
Commenting on the findings, Ross Jones, director Of Enviro Homes Renewables, says: “While there are many ways you can save money on energy for your home, having a low energy efficiency rating can make this very difficult from the start, and costs will add up, and with the current cost of living this can be a serious problem. However, if you live in one of these areas, you can improve your EPC rating by installing insulation, changing your lighting, replacing your boiler, and more.”
