The last few years
Each row is a full twelve months of decisions, ending in the quarter shown

By type of application
Year to September 2026 · types with at least ten decisions
The headline median mixes every kind of application together. A householder extension and an outline application for a housing site are not the same job, and the difference between them is usually larger than the difference between two councils.

What Islington decides
Year to September 2026
Islington issued 2,175 decisions in the year to September 2026. Of the clear-cut outcomes, 91% were approvals: 1,854 granted against 184 refused. Split decisions, withdrawals and other outcomes sit outside that percentage rather than being counted as either.
Speed and approval rate are separate things. A council that refuses quickly is not doing the same job as one that negotiates an approval slowly, and neither figure alone says which served the applicant better.
