Across 3,445 assessed properties, SR1 achieves an average EPC score of 69 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so SR1 is around that benchmark. The most common rating band is C, with 8.2% of homes rated A or B and 83.3% in the C or D bands. Meanwhile, 0.8% 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.

Walk through SR1 and you will mostly see flats. Flats alone account for 75% of all certificated properties — a distinctly urban profile. Around 13% of properties are owner-occupied , while 34% are privately rented and 53% are social housing. 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 69 to 78 — a 9-point jump that would lift the typical rating to C.
