NW11 is around the national average for energy efficiency.
Looking at the energy data for NW11, this Barnet district scores an average of 64 out of 100, placing it around the national average. Compared to the national average of 67, that puts NW11 around the norm for England and Wales. The most common rating band is D, with 8.3% of homes rated A or B and 73.0% in the C or D bands. Meanwhile, 2.7% 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.
The area is characterised by flats. Flats alone account for 58% of all certificated properties — a distinctly urban profile. Around 46% of properties are owner-occupied , while 47% are privately rented . That high proportion of rental homes matters — landlords in NW11 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 89% 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 64 to 77 — a 13-point jump that would lift the typical rating to C.

Frequently asked questions
What is the average EPC rating in NW11?
Homes in NW11 have an average EPC rating of D, scoring 64 out of 100 for energy efficiency. That figure comes from 9,850 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 NW11 are rated F or G?
2.7% of homes in NW11 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 NW11 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.
