GL4 is around the national average for energy efficiency.
For the 14,429 homes assessed in GL4, the average energy score comes in at 67 out of 100, placing it around the national average. The national average is 67, which means GL4 performs roughly in line with the rest of the country. The most common rating band is D, with 8.2% of homes rated A or B and 81.7% in the C or D bands. Meanwhile, 1.9% 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.
Houses make up the bulk of the housing in this district. Around 65% of properties are owner-occupied and 21% are social housing. Gas central heating is the main fuel source for 91% 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 67 to 81 — a 14-point jump that would lift the typical rating to B.

Frequently asked questions
What is the average EPC rating in GL4?
Homes in GL4 have an average EPC rating of D, scoring 67 out of 100 for energy efficiency. That figure comes from 14,429 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 GL4 are rated F or G?
1.9% of homes in GL4 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
This is actually better than the national picture, suggesting the housing stock in GL4 is in relatively good shape — though any home rated F or G would still benefit enormously from basic upgrades. Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
