W1K is around the national average for energy efficiency.
Looking at the energy data for W1K, this Westminster district scores an average of 67 out of 100, placing it around the national average. Compared to the national average of 67, that puts W1K around the norm for England and Wales. The most common rating band is C, with 13.5% of homes rated A or B and 70.4% in the C or D bands. Meanwhile, 2.4% 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.
The area is characterised by flats. Flats alone account for 85% of all certificated properties — a distinctly urban profile. Around 46% of properties are owner-occupied , while 46% are privately rented . That high proportion of rental homes matters — landlords in W1K 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 75% 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 67 to 77 — a 10-point jump that would lift the typical rating to C.

Frequently asked questions
What is the average EPC rating in W1K?
Homes in W1K have an average EPC rating of D, scoring 67 out of 100 for energy efficiency. That figure comes from 1,972 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 W1K are rated F or G?
2.4% of homes in W1K 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 W1K 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.
