Looking at the energy data for HR3, this Powys district scores an average of 56 out of 100, placing it below the national average. Compared to the national average of 67, that puts HR3 below the norm for England and Wales. The most common rating band is D, with 10.4% of homes rated A or B and 48.3% in the C or D bands. Meanwhile, 18.6% 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.

The area is characterised by houses. Around 73% of properties are owner-occupied . Oil-fired heating is common in this part of HR3, 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 56 to 80 — a 24-point jump that would lift the typical rating to C. That is a substantial gain, suggesting many homes are missing basic efficiency measures.
