Measure
Property type
EPC records are not a census of every home. They cover properties assessed for sale, letting, construction or another qualifying event. Local property age, type and tenure can affect comparisons. Potential scores assume recommended improvements are completed.

Methodology and limitations
Certificate selection
The latest valid domestic EPC per UPRN, lodged within the preceding 10 years and mapped to current council geography.
Sample threshold
100 certificates are required for bungalows. This reduces unstable comparisons from small samples.
Measures
Median scores use EPC points. Rating shares show the percentage in bands A–C or E–G. Improvement potential is the median difference between current and potential scores.
Interpretation
These figures describe assessed properties, not every dwelling. They do not directly measure bills, household energy use, carbon emissions or retrofit cost.
