Based on 394 Energy Performance Certificates, EC4V in City of London has an average EPC score of 71 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 14.5% of homes rated A or B and 77.4% in the C or D bands. Meanwhile, 1.5% 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 96% of all certificated properties — a distinctly urban profile. Around 43% of properties are owner-occupied , while 55% are privately rented . That high proportion of rental homes matters — landlords in EC4V 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 71 to 78 — a 7-point jump that would lift the typical rating to C.
