GU11 is around the national average for energy efficiency.
Data from 9,908 property assessments shows GU11 averaging 71 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so GU11 is around that benchmark. The most common rating band is C, with 22.9% of homes rated A or B and 69.4% in the C or D bands. Meanwhile, 1.1% 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.
Walk through GU11 and you will mostly see houses. Flats make up a notable 39% of homes here. Around 48% of properties are owner-occupied , while 29% are privately rented and 23% are social housing. Gas central heating is the main fuel source for 83% 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 71 to 82 — a 11-point jump that would lift the typical rating to B.
