L37 is around the national average for energy efficiency.
Based on 6,675 Energy Performance Certificates, L37 in Sefton has an average EPC score of 66 out of 100, placing it around the national average. To put this in context, the national average sits at 67. The most common rating band is D, with 13.4% of homes rated A or B and 70.8% in the C or D bands. Meanwhile, 2.5% 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.
Most of the housing stock here consists of houses. Around 85% of properties are owner-occupied . Gas central heating is the main fuel source for 94% 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 66 to 80 — a 14-point jump that would lift the typical rating to C.

Frequently asked questions
What is the average EPC rating in L37?
Homes in L37 have an average EPC rating of D, scoring 66 out of 100 for energy efficiency. That figure comes from 6,675 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 L37 are rated F or G?
2.5% of homes in L37 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 L37 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.
