Based on 14,914 Energy Performance Certificates, E5 in Hackney has an average EPC score of 69 out of 100, placing it around the national average. To put this in context, the national average sits at 67. The most common rating band is C, with 12.7% of homes rated A or B and 79.0% in the C or D bands. Meanwhile, 1.1% 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.

Most of the housing stock here consists of flats. Flats alone account for 71% of all certificated properties — a distinctly urban profile. Around 35% of properties are owner-occupied , while 36% are privately rented and 29% are social housing. That high proportion of rental homes matters — landlords in E5 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. Gas central heating is the main fuel source for 85% 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 69 to 78 — a 9-point jump that would lift the typical rating to C.
