The 3,177 EPC certificates on record for WC1X paint a clear picture — the area averages 72 out of 100, placing it above the national average. The national average is 67, which means WC1X performs better than most areas. The most common rating band is C, with 25.4% of homes rated A or B and 68.4% in the C or D bands. Meanwhile, 0.8% 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 84% of all certificated properties — a distinctly urban profile. Around 27% of properties are owner-occupied , while 40% are privately rented and 33% are social housing. That high proportion of rental homes matters — landlords in WC1X 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. Gas central heating is the main fuel source for 68% of homes, which is typical for urban areas across England.

There is genuine room for improvement here. If every recommended upgrade were carried out, the average score could climb from 72 to 78 — a 6-point jump that would lift the typical rating to C.
