Frequently asked questions

What is the average EPC rating in RH15?

Homes in RH15 have an average EPC rating of C, scoring 70 out of 100 for energy efficiency. That figure comes from 10,727 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 RH15 are rated F or G?

1.2% of homes in RH15 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 RH15 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.
