Across 1,463 assessed properties, EX21 achieves an average EPC score of 55 out of 100, placing it below the national average. For reference, the England and Wales average is 67 — so EX21 is below that benchmark. The most common rating band is D, with 10.5% of homes rated A or B and 45.2% in the C or D bands. Meanwhile, 17.4% 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 EX21 and you will mostly see houses. Around 84% of properties are owner-occupied . Oil-fired heating is common in this part of EX21, reflecting the more rural character of the area and limited mains gas coverage.

There is genuine room for improvement here. If every recommended upgrade were carried out, the average score could climb from 55 to 82 — a 27-point jump that would lift the typical rating to B. That is a substantial gain, suggesting many homes are missing basic efficiency measures.
