London Borough of Lambeth

Planning appeal decisions, 2016–2026

Householder appeals

In the 12 months to 28 August 2026

10 allowed and 18 dismissed (28 decided). That is 0.2 percentage points above the national average of 35.5%. Across all years: 40.6% of 308 decided.

Small sample: with this few decisions the percentage can swing a lot from one year to the next.

Allowed ÷ (allowed + dismissed). Split decisions, withdrawn, invalid and undetermined appeals are left out. Based on completed records in the Appeal Scout archive, which runs a little behind today's date because decisions are added after publication.

Householder appeals allowed, year by year

Dashed outlines mark years with fewer than 10 decided appeals, too few to chart. 2016 starts in April and 2026 runs to 28 August.
