4.2% of homes are rated F or G — above the national average of 2.9%.
Energy efficiency in TA9 (Somerset) sits at an average score of 67 out of 100, placing it around the national average. To put this in context, the national average sits at 67. The most common rating band is C, with 19.9% of homes rated A or B and 63.9% in the C or D bands. Meanwhile, 4.2% 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.
Most of the housing stock here consists of houses. Around 62% of properties are owner-occupied and 26% are social housing. Gas central heating is the main fuel source for 72% 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 67 to 82 — a 15-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 TA9?
Homes in TA9 have an average EPC rating of D, scoring 67 out of 100 for energy efficiency. That figure comes from 4,696 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 TA9 are rated F or G?
4.2% of homes in TA9 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means TA9 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.
