DL16 is around the national average for energy efficiency.
When it comes to energy performance, DL16 in County Durham manages an average of 70 out of 100, placing it around the national average. Compared to the national average of 67, that puts DL16 around the norm for England and Wales. The most common rating band is C, with 22.2% of homes rated A or B and 68.7% in the C or D bands. Meanwhile, 1.4% 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 55% of properties are owner-occupied and 32% are social housing. Gas central heating is the main fuel source for 98% 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 70 to 84 — a 14-point jump that would lift the typical rating to B.
