The 4,380 EPC certificates on record for MK9 paint a clear picture — the area averages 79 out of 100, placing it above the national average. The national average is 67, which means MK9 performs better than most areas. The most common rating band is B, with 51.6% of homes rated A or B and 46.4% 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.

Flats make up the bulk of the housing in this district. Flats alone account for 92% of all certificated properties — a distinctly urban profile. Around 40% of properties are owner-occupied , while 40% are privately rented and 20% are social housing. That high proportion of rental homes matters — landlords in MK9 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 79 to 81 — a 2-point jump that would lift the typical rating to B.
