Data from 2,457 property assessments shows L2 averaging 72 out of 100, placing it above the national average. For reference, the England and Wales average is 67 — so L2 is above that benchmark. The most common rating band is C, with 20.3% of homes rated A or B and 73.5% in the C or D bands. Meanwhile, 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 L2 and you will mostly see flats. Flats alone account for 99% of all certificated properties — a distinctly urban profile. Around 67% of properties are owner-occupied , while 32% are privately rented . 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 72 to 75 — a 3-point jump that would lift the typical rating to C. If you live in L2 and want to reduce your energy bills, start with our guide to loft insulation — it is one of the most cost-effective upgrades you can make.
