For the 151 homes assessed in EC4M, the average energy score comes in at 69 out of 100, placing it around the national average. The national average is 67, which means EC4M performs roughly in line with the rest of the country. The most common rating band is C, with 4.6% of homes rated A or B and 90.1% in the C or D bands. Meanwhile, 1.3% 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 97% of all certificated properties — a distinctly urban profile. Around 59% of properties are owner-occupied , while 41% are privately rented . That high proportion of rental homes matters — landlords in EC4M 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 69 to 77 — a 8-point jump that would lift the typical rating to C.
