Looking at the energy data for SW1V, this Westminster district scores an average of 69 out of 100, placing it around the national average. Compared to the national average of 67, that puts SW1V around the norm for England and Wales. The most common rating band is C, with 6.8% of homes rated A or B and 84.0% 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.

The area is characterised by flats. Flats alone account for 86% of all certificated properties — a distinctly urban profile. Around 31% of properties are owner-occupied , while 42% are privately rented and 27% are social housing. That high proportion of rental homes matters — landlords in SW1V 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 87% 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 69 to 77 — a 8-point jump that would lift the typical rating to C.
