Data from 936 property assessments shows EC1A averaging 74 out of 100, placing it above the national average. For reference, the England and Wales average is 67 — so EC1A is above that benchmark. The most common rating band is C, with 35.3% of homes rated A or B and 59.1% 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.

Walk through EC1A and you will mostly see flats. Flats alone account for 97% of all certificated properties — a distinctly urban profile. Around 52% of properties are owner-occupied , while 42% are privately rented . That high proportion of rental homes matters — landlords in EC1A 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 74 to 80 — a 6-point jump that would lift the typical rating to C.
