Across 2,485 assessed properties, B4 achieves an average EPC score of 81 out of 100, placing it above the national average. For reference, the England and Wales average is 67 — so B4 is above that benchmark. The most common rating band is B, with 69.2% of homes rated A or B and 30.6% in the C or D bands. In practical terms, a B rating indicates well-insulated homes with efficient heating — energy bills here tend to be well below average.

Walk through B4 and you will mostly see flats. Flats alone account for 98% of all certificated properties — a distinctly urban profile. Around 9% of properties are owner-occupied , while 77% are privately rented . That high proportion of rental homes matters — landlords in B4 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 81 to 82 — a 1-point jump that would lift the typical rating to B.
