NN13 is around the national average for energy efficiency.
Across 6,933 assessed properties, NN13 achieves an average EPC score of 69 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so NN13 is around that benchmark. The most common rating band is C, with 25.7% of homes rated A or B and 61.1% in the C or D bands. Meanwhile, 2.9% 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.
Walk through NN13 and you will mostly see houses. Around 72% of properties are owner-occupied . Gas central heating is the main fuel source for 75% 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 83 — a 14-point jump that would lift the typical rating to B.

Frequently asked questions
What is the average EPC rating in NN13?

What percentage of homes in NN13 are rated F or G?
2.9% of homes in NN13 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.

Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
