Based on 10,083 Energy Performance Certificates, S3 in Sheffield has an average EPC score of 74 out of 100, placing it above the national average. To put this in context, the national average sits at 67. The most common rating band is C, with 30.1% of homes rated A or B and 64.4% in the C or D bands. Meanwhile, 0.7% 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.

Most of the housing stock here consists of flats. Flats alone account for 80% of all certificated properties — a distinctly urban profile. Around 25% of properties are owner-occupied , while 41% are privately rented and 34% are social housing. That high proportion of rental homes matters — landlords in S3 must comply with the Minimum Energy Efficiency Standards (MEES), which currently require at least an EPC E rating. Properties rated F or G cannot legally be let. A significant share of homes here rely on electric heating, which tends to be more expensive per unit of energy than gas.

There is genuine room for improvement here. If every recommended upgrade were carried out, the average score could climb from 74 to 80 — a 6-point jump that would lift the typical rating to C.
