What the figures cover
- Only homes that have had an EPC. The register mostly holds homes that were sold, let or built since 2008, so the figures describe certified homes, not every home.
- Each home is counted once, by its latest certificate.
- The league tables rank postcode sectors with at least 2,000 homes with an EPC and districts with at least 3,000. The most extreme ranks are sensitive to that threshold.
- Rates are rounded to one decimal place, so 100% means at least 99.95%.
