Homes in SY20 have an average EPC rating of E, scoring 51 out of 100 for energy efficiency. That figure comes from 2,207 certificates issued across the district.
That is below the national average of 67, which means there is real scope to improve energy efficiency here. An E rating suggests many homes here are losing significant amounts of heat — and money — through poor insulation or outdated heating systems.
What percentage of homes in SY20 are rated F or G?
26% of homes in SY20 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means SY20 has a higher-than-average proportion of poorly insulated homes. On the positive side, many of these properties may qualify for free improvements through government schemes like ECO4 or the Great British Insulation Scheme. Landlords should note that F and G rated properties cannot legally be rented out under current MEES rules.
