Data from 11,108 property assessments shows W10 averaging 69 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so W10 is around that benchmark. The most common rating band is C, with 13.6% of homes rated A or B and 77.8% in the C or D bands. Meanwhile, 0.9% 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 W10 and you will mostly see flats. Flats alone account for 73% of all certificated properties — a distinctly urban profile. Around 32% of properties are owner-occupied , while 23% are privately rented and 45% are social housing. Gas central heating is the main fuel source for 85% 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 78 — a 9-point jump that would lift the typical rating to C.
