LE12 is around the national average for energy efficiency.
3% of homes are rated F or G — above the national average of 2.9%.
Across 23,120 assessed properties, LE12 achieves an average EPC score of 68 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so LE12 is around that benchmark. The most common rating band is D, with 25.6% of homes rated A or B and 60.0% in the C or D bands. Meanwhile, 3% 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.
Walk through LE12 and you will mostly see houses. Around 72% of properties are owner-occupied . 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 68 to 84 — a 16-point jump that would lift the typical rating to B. That is a substantial gain, suggesting many homes are missing basic efficiency measures.

Frequently asked questions
What is the average EPC rating in LE12?
Homes in LE12 have an average EPC rating of D, scoring 68 out of 100 for energy efficiency. That figure comes from 23,120 certificates issued across the district.
This is broadly in line with the national average of 67 — neither particularly efficient nor particularly wasteful. A D rating typically means higher-than-necessary heating bills, especially in older properties without adequate insulation.
What percentage of homes in LE12 are rated F or G?
3% of homes in LE12 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means LE12 has a higher-than-average proportion of poorly insulated homes. On the positive side, many of these properties may qualify for free improvements through government schemes like ECO4 or the Great British Insulation Scheme. Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
