SG15 is around the national average for energy efficiency.
Based on 2,060 Energy Performance Certificates, SG15 in Central Bedfordshire has an average EPC score of 68 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 15.2% of homes rated A or B and 74.6% in the C or D bands. Meanwhile, 0.8% 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 houses. Around 65% of properties are owner-occupied and 20% 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 83 — a 15-point jump that would lift the typical rating to B. That is a substantial gain, suggesting many homes are missing basic efficiency measures.

Frequently asked questions
What is the average EPC rating in SG15?
Homes in SG15 have an average EPC rating of D, scoring 68 out of 100 for energy efficiency. That figure comes from 2,060 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 SG15 are rated F or G?
0.8% of homes in SG15 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 SG15 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.
