EPC band distribution by local authority
Each bar shows the proportion of properties in each EPC band, from A (most efficient) on the left to G (least efficient) on the right.
| Local authority | Properties | Mode band | Avg score | Band distribution |
|---|---|---|---|---|
| Bradford | 235 | D | 54.6 | |
| Calderdale | 91 | C | 64 | |
| Kirklees | 216 | D | 56.1 | |
| Leeds | 293 | D | 60.2 | |
| Wakefield | 131 | D | 55.2 |
“Mode band” is the most common band in that authority. “Avg score” is the mean current-energy-efficiency value, on the 0–100 scale used by EPCs.

What the data shows
The EPC band is the headline figure on a property’s Energy Performance Certificate, on a scale from A (most efficient) to G (least efficient). A band D is “typical” for English housing — new building regulations target band B and above, while a large share of older homes sit at D, E or below.
For West Yorkshire, the headline that matters for retrofit policy is the share of homes at D or below — these are the properties that benefit most from insulation and heating upgrades, and they form the target group for most current funding routes. Schemes like ECO4 are explicitly targeted at homes rated D or worse, and the upcoming Warm Homes: Local Grant is expected to follow a similar focus.
At postcode-area level, the data reflects the underlying housing stock. Areas dominated by older solid-wall terraces — common across central Leeds, Bradford, and the Calder valley — typically show a higher concentration of D–F bands than areas with newer post-war or modern stock. Insulating those properties properly is the biggest single lever on the region’s residential carbon emissions and on fuel-poverty risk.
Methodology
Sample-based aggregation. Queries a hand-picked set of 80 representative West Yorkshire postcodes against the official Department for Energy Security and Net Zero Domestic EPC API, deduplicates by UPRN (keeping the most recent registration), and aggregates the resulting properties by local authority and outward postcode area. The score column shows an estimated mean efficiency derived from EPC band midpoints — the search API's band-only response doesn't include the underlying numeric score. For full coverage of every certificate, the API's bulk-CSV download (/api/files/domestic/csv) is the canonical route.
Deduplication. When a property has been issued more than one EPC over time (for example, before and after a retrofit), only the most recent certificate is counted — so the figures here approximate the current state of the housing stock rather than a count of every certificate ever issued.
Coverage. Domestic EPCs only. Display Energy Certificates (issued for public buildings) and non-domestic EPCs (commercial property) are not included. Properties without a valid EPC do not appear in the dataset at all — older properties never sold or rented since 2008 may be under-represented.
Source. Department for Energy Security and Net Zero EPC data, accessed via the official EPC API. Data is published under the Open Government Licence v3.
Date range. Certificates issued between 2012-04-11 and 2026-06-03.
