Across 14,706 assessed properties, BS23 achieves an average EPC score of 64 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so BS23 is around that benchmark. The most common rating band is D, with 7.8% of homes rated A or B and 72.3% in the C or D bands. Meanwhile, 3.3% of homes sit in the F or G bands — the least efficient categories. In practical terms, a rating of D means many homes here lose more heat than average — potentially adding £200-400 per year to energy bills compared to a C-rated home.

Walk through BS23 and you will mostly see flats. Flats alone account for 59% of all certificated properties — a distinctly urban profile. Around 50% of properties are owner-occupied , while 30% are privately rented and 20% are social housing. Gas central heating is the main fuel source for 79% of homes, which is typical for urban areas across England.

There is genuine room for improvement here. If every recommended upgrade were carried out, the average score could climb from 64 to 77 — a 13-point jump that would lift the typical rating to C.
