Across 11,809 assessed properties, PO1 achieves an average EPC score of 70 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so PO1 is around that benchmark. The most common rating band is C, with 9.7% of homes rated A or B and 84.4% in the C or D bands. Meanwhile, 0.9% 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 PO1 and you will mostly see flats. Flats alone account for 58% of all certificated properties — a distinctly urban profile. Around 31% of properties are owner-occupied , while 28% are privately rented and 41% are social housing. Gas central heating is the main fuel source for 77% 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 70 to 79 — a 9-point jump that would lift the typical rating to C.
