Figures computed from decided planning applications published by each borough: the October 2026 snapshot, computed 10 October 2026. Coverage: 33 London planning authorities. A borough with fewer than 20 decisions in the window is shown as “too few decisions” rather than ranked, and one that records no refusals across 100 or more decisions is left unranked until we can read its decision wording.
