EC3A is above average for energy efficiency — better than most areas in England and Wales.
Energy efficiency in EC3A (City of London) sits at an average score of 80 out of 100, placing it above the national average. To put this in context, the national average sits at 67. The most common rating band is B, with 76.9% of homes rated A or B and 21.1% in the C or D bands. In practical terms, a B rating indicates well-insulated homes with efficient heating — energy bills here tend to be well below average.
Most of the housing stock here consists of flats. Flats alone account for 99% of all certificated properties — a distinctly urban profile. Around 33% of properties are owner-occupied , while 67% are privately rented . That high proportion of rental homes matters — landlords in EC3A 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.
There is genuine room for improvement here. If every recommended upgrade were carried out, the average score could climb from 80 to 82 — a 2-point jump that would lift the typical rating to B.
