GU12 is around the national average for energy efficiency.
For the 10,746 homes assessed in GU12, the average energy score comes in at 68 out of 100, placing it around the national average. The national average is 67, which means GU12 performs roughly in line with the rest of the country. The most common rating band is D, with 18.2% of homes rated A or B and 69.9% 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 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. Flats make up a notable 22% of homes here. Around 71% of properties are owner-occupied and 18% are social housing. 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 68 to 82 — a 14-point jump that would lift the typical rating to B.

Frequently asked questions
What is the average EPC rating in GU12?
Homes in GU12 have an average EPC rating of D, scoring 68 out of 100 for energy efficiency. That figure comes from 10,746 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 GU12 are rated F or G?
1.4% of homes in GU12 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 GU12 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.
