For the 14,187 homes assessed in W6, the average energy score comes in at 69 out of 100, placing it around the national average. The national average is 67, which means W6 performs roughly in line with the rest of the country. The most common rating band is C, with 14.3% of homes rated A or B and 76.2% in the C or D bands. Meanwhile, 1.3% 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 72% of all certificated properties — a distinctly urban profile. Around 37% of properties are owner-occupied , while 39% are privately rented and 24% are social housing. That high proportion of rental homes matters — landlords in W6 must comply with the Minimum Energy Efficiency Standards (MEES), which currently require at least an EPC E rating. Properties rated F or G cannot legally be let. 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 69 to 78 — a 9-point jump that would lift the typical rating to C.
