CT7 is around the national average for energy efficiency.
Data from 4,339 property assessments shows CT7 averaging 64 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so CT7 is around that benchmark. The most common rating band is D, with 6.8% of homes rated A or B and 77.5% in the C or D bands. Meanwhile, 2.9% of homes sit in the F or G bands — the least efficient categories. In practical terms, a rating of D means many homes here lose more heat than average — potentially adding £200-400 per year to energy bills compared to a C-rated home.
Walk through CT7 and you will mostly see houses. Around 76% of properties are owner-occupied . Gas central heating is the main fuel source for 86% 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 64 to 80 — a 16-point jump that would lift the typical rating to C. That is a substantial gain, suggesting many homes are missing basic efficiency measures.

Frequently asked questions
What is the average EPC rating in CT7?
Homes in CT7 have an average EPC rating of D, scoring 64 out of 100 for energy efficiency. That figure comes from 4,339 certificates issued across the district.
This is broadly in line with the national average of 67 — neither particularly efficient nor particularly wasteful. A D rating typically means higher-than-necessary heating bills, especially in older properties without adequate insulation.
What percentage of homes in CT7 are rated F or G?
2.9% of homes in CT7 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
This is actually better than the national picture, suggesting the housing stock in CT7 is in relatively good shape — though any home rated F or G would still benefit enormously from basic upgrades. Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
