TN27 is around the national average for energy efficiency.
6.9% of homes are rated F or G — above the national average of 2.9%.
For the 4,487 homes assessed in TN27, the average energy score comes in at 65 out of 100, placing it around the national average. The national average is 67, which means TN27 performs roughly in line with the rest of the country. The most common rating band is D, with 23.7% of homes rated A or B and 53.4% in the C or D bands. Meanwhile, 6.9% 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.
Houses make up the bulk of the housing in this district. Around 72% of properties are owner-occupied and 17% are social housing. Gas central heating is the main fuel source for 67% 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 65 to 84 — a 19-point jump that would lift the typical rating to B. That is a substantial gain, suggesting many homes are missing basic efficiency measures.

Frequently asked questions
What is the average EPC rating in TN27?
Homes in TN27 have an average EPC rating of D, scoring 65 out of 100 for energy efficiency. That figure comes from 4,487 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 TN27 are rated F or G?
6.9% of homes in TN27 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means TN27 has a higher-than-average proportion of poorly insulated homes. On the positive side, many of these properties may qualify for free improvements through government schemes like ECO4 or the Great British Insulation Scheme. Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
