Across 9,202 assessed properties, SE11 achieves an average EPC score of 71 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so SE11 is around that benchmark. The most common rating band is C, with 20.5% of homes rated A or B and 72.9% in the C or D bands. Meanwhile, 1.1% 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.

Walk through SE11 and you will mostly see flats. Flats alone account for 79% of all certificated properties — a distinctly urban profile. Around 37% of properties are owner-occupied , while 22% are privately rented and 42% are social housing. Gas central heating is the main fuel source for 77% 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 71 to 78 — a 7-point jump that would lift the typical rating to C.
