There are 65 conservation areas in Lambeth, and many are tiny, down to Roupell Street with its 77 houses and 1.9 hectares and not a single heat pump. Article 4 directions are published for 37 areas, but what exactly they remove is impossible to tell from the data; the other 28 have none. If your area is in the first group, start by reading the text of its own direction; in the second, the general conservation area rules are enough.
From South Bank to Mitre Road
Solid walls without insulation account for 64.5% of homes in these areas against 48.7% across England’s conservation areas, but the housing stock is mixed. In South Bank it is 19% of 1,395 houses, and there is no gas at all. In Mitre Road & Ufford Street every one of the 160 houses has such walls, and 94% have gas. The EPC register shows 164 heat pumps as of November 2026: 50 in the largest area, Clapham, and another 28 on Clapham High Street.
The area’s own page shows its boundary; the council can tell you more precisely. The rules are the national ones as at 21 October 2026, and planning decisions are made by Lambeth Council.
