W5 is around the national average for energy efficiency.
Data from 17,976 property assessments shows W5 averaging 66 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so W5 is around that benchmark. The most common rating band is D, with 10.3% of homes rated A or B and 75.7% in the C or D bands. Meanwhile, 2% of homes sit in the F or G bands — the least efficient categories. In practical terms, a rating of D means many homes here lose more heat than average — potentially adding £200-400 per year to energy bills compared to a C-rated home.
Walk through W5 and you will mostly see flats. Flats alone account for 65% of all certificated properties — a distinctly urban profile. Around 48% of properties are owner-occupied , while 44% are privately rented . That high proportion of rental homes matters — landlords in W5 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 84% 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 66 to 77 — a 11-point jump that would lift the typical rating to C.

Frequently asked questions
What is the average EPC rating in W5?
Homes in W5 have an average EPC rating of D, scoring 66 out of 100 for energy efficiency. That figure comes from 17,976 certificates issued across the district.
This is broadly in line with the national average of 67 — neither particularly efficient nor particularly wasteful. A D rating typically means higher-than-necessary heating bills, especially in older properties without adequate insulation.
What percentage of homes in W5 are rated F or G?
2% of homes in W5 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
This is actually better than the national picture, suggesting the housing stock in W5 is in relatively good shape — though any home rated F or G would still benefit enormously from basic upgrades. Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
