Looking at the energy data for DE11, this South Derbyshire district scores an average of 69 out of 100, placing it around the national average. Compared to the national average of 67, that puts DE11 around the norm for England and Wales. The most common rating band is C, with 20.2% of homes rated A or B and 67.8% in the C or D bands. Meanwhile, 2.3% 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.

The area is characterised by houses. Around 64% of properties are owner-occupied and 19% are social housing. Gas central heating is the main fuel source for 92% 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 69 to 84 — 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.
