NW4 is around the national average for energy efficiency.
The 10,107 EPC certificates on record for NW4 paint a clear picture — the area averages 66 out of 100, placing it around the national average. The national average is 67, which means NW4 performs roughly in line with the rest of the country. The most common rating band is C, with 8.8% of homes rated A or B and 77.2% 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 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 62% of all certificated properties — a distinctly urban profile. Around 42% of properties are owner-occupied , while 46% are privately rented . That high proportion of rental homes matters — landlords in NW4 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 78 — a 12-point jump that would lift the typical rating to C.

Frequently asked questions
What is the average EPC rating in NW4?
Homes in NW4 have an average EPC rating of D, scoring 66 out of 100 for energy efficiency. That figure comes from 10,107 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 NW4 are rated F or G?
2% of homes in NW4 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 NW4 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.
