The 7,760 EPC certificates on record for B12 paint a clear picture — the area averages 69 out of 100, placing it around the national average. The national average is 67, which means B12 performs roughly in line with the rest of the country. The most common rating band is C, with 21.2% of homes rated A or B and 66.4% in the C or D bands. Meanwhile, 1.7% of homes sit in the F or G bands — the least efficient categories. In practical terms, a C rating suggests reasonably efficient homes, though there is still room for improvement on heating and insulation.

Flats make up the bulk of the housing in this district. Flats alone account for 54% of all certificated properties — a distinctly urban profile. Around 34% of properties are owner-occupied , while 25% are privately rented and 41% are social housing. Gas central heating is the main fuel source for 65% 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 69 to 80 — a 11-point jump that would lift the typical rating to C.
