BL1 is around the national average for energy efficiency.
For the 22,274 homes assessed in BL1, the average energy score comes in at 66 out of 100, placing it around the national average. The national average is 67, which means BL1 performs roughly in line with the rest of the country. The most common rating band is C, with 8.1% of homes rated A or B and 78.2% 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.
Houses make up the bulk of the housing in this district. Flats make up a notable 27% of homes here. Around 56% of properties are owner-occupied , while 23% are privately rented and 21% are social housing. 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 80 — a 14-point jump that would lift the typical rating to C.

Frequently asked questions
What is the average EPC rating in BL1?
Homes in BL1 have an average EPC rating of D, scoring 66 out of 100 for energy efficiency. That figure comes from 22,274 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 BL1 are rated F or G?
2.4% of homes in BL1 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 BL1 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.
