For the 19,883 homes assessed in SE16, the average energy score comes in at 74 out of 100, placing it above the national average. The national average is 67, which means SE16 performs better than most areas. The most common rating band is C, with 27.9% of homes rated A or B and 67.1% in the C or D bands. Meanwhile, 0.4% 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 74% of all certificated properties — a distinctly urban profile. Around 37% of properties are owner-occupied , while 35% are privately rented and 28% are social housing. Gas central heating is the main fuel source for 62% 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 74 to 80 — a 6-point jump that would lift the typical rating to C.
