EC3R is above average for energy efficiency — better than most areas in England and Wales.
When it comes to energy performance, EC3R in City of London manages an average of 78 out of 100, placing it above the national average. Compared to the national average of 67, that puts EC3R above the norm for England and Wales. The most common rating band is B, with 58.4% of homes rated A or B and 39.1% in the C or D bands. Meanwhile, 0.6% of homes sit in the F or G bands — the least efficient categories. In practical terms, a B rating indicates well-insulated homes with efficient heating — energy bills here tend to be well below average.
The area is characterised by flats. Flats alone account for 97% of all certificated properties — a distinctly urban profile. Around 36% of properties are owner-occupied , while 63% are privately rented . That high proportion of rental homes matters — landlords in EC3R 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 78 to 81 — a 3-point jump that would lift the typical rating to B.
