Data from 4,204 property assessments shows TR4 averaging 58 out of 100, placing it below the national average. For reference, the England and Wales average is 67 — so TR4 is below that benchmark. The most common rating band is D, with 13.4% of homes rated A or B and 46.4% in the C or D bands. Meanwhile, 14.6% 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 TR4 and you will mostly see houses. Around 71% of properties are owner-occupied , while 24% are privately rented . 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 58 to 82 — a 24-point jump that would lift the typical rating to B. That is a substantial gain, suggesting many homes are missing basic efficiency measures.
