RG23 is around the national average for energy efficiency.
Data from 4,868 property assessments shows RG23 averaging 71 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so RG23 is around that benchmark. The most common rating band is B, with 33.9% of homes rated A or B and 57.9% in the C or D bands. Meanwhile, 1% of homes sit in the F or G bands — the least efficient categories. In practical terms, a B rating indicates well-insulated homes with efficient heating — energy bills here tend to be well below average.
