BD1 is around the national average for energy efficiency.
For the 4,104 homes assessed in BD1, the average energy score comes in at 68 out of 100, placing it around the national average. The national average is 67, which means BD1 performs roughly in line with the rest of the country. The most common rating band is C, with 9.0% of homes rated A or B and 78.5% in the C or D bands. Meanwhile, 1.5% 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 93% of all certificated properties — a distinctly urban profile. Around 38% of properties are owner-occupied , while 52% are privately rented . That high proportion of rental homes matters — landlords in BD1 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. A significant share of homes here rely on electric heating, which tends to be more expensive per unit of energy than gas.
There is genuine room for improvement here. If every recommended upgrade were carried out, the average score could climb from 68 to 75 — a 7-point jump that would lift the typical rating to C.

Frequently asked questions
What is the average EPC rating in BD1?
Homes in BD1 have an average EPC rating of D, scoring 68 out of 100 for energy efficiency. That figure comes from 4,104 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 BD1 are rated F or G?
1.5% of homes in BD1 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 BD1 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.
