KT16 is around the national average for energy efficiency.
3.9% of homes are rated F or G — above the national average of 2.9%.
Data from 7,200 property assessments shows KT16 averaging 68 out of 100, placing it around the national average. For reference, the England and Wales average is 67 — so KT16 is around that benchmark. The most common rating band is C, with 20.2% of homes rated A or B and 65.1% in the C or D bands. Meanwhile, 3.9% 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 KT16 and you will mostly see houses. Flats make up a notable 36% of homes here. Around 69% of properties are owner-occupied and 16% are social housing. Gas central heating is the main fuel source for 78% 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 80 — a 12-point jump that would lift the typical rating to C.

Frequently asked questions
What is the average EPC rating in KT16?
Homes in KT16 have an average EPC rating of D, scoring 68 out of 100 for energy efficiency. That figure comes from 7,200 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 KT16 are rated F or G?
3.9% of homes in KT16 fall into the F or G bands — the lowest energy efficiency ratings. Nationally, the figure is 2.9%.
That means KT16 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.
