SO22 is around the national average for energy efficiency.
Energy efficiency in SO22 (Winchester) sits at an average score of 71 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 C, with 22.8% of homes rated A or B and 69.5% in the C or D bands. Meanwhile, 1.2% 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.

Frequently asked questions
What is the average EPC rating in SO22?
Homes in SO22 have an average EPC rating of C, scoring 71 out of 100 for energy efficiency. That figure comes from 9,487 certificates issued across the district.
This is broadly in line with the national average of 67 — neither particularly efficient nor particularly wasteful.
What percentage of homes in SO22 are rated F or G?
1.2% of homes in SO22 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 SO22 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.
