Data sources & method

Applications. Sourced from the Greater London Authority (GLA) Planning Datahub and Islington Council’s online planning register. Covers full planning, householder, and minor residential applications of nine units or fewer decided in the window shown above.

Decisions and timing. Outcomes and determination times are taken from the council’s published decision notices.

Refusal reasons. Extracted from refused decision notices that were publicly available. Not every refusal has a readable notice, so totals count all refusals but the reason breakdown covers only those we could read.

Scheme classification. Site types (conversion, demolish & rebuild, extension, and so on) are coded from application descriptions and drawings. Areas are mapped from postcodes and ward names using the council’s own sub-area definitions.

Update frequency. Refreshed quarterly. Next refresh: July 2026.

Nothing here is planning advice. Outcomes are historical and do not predict individual cases. Approval rates vary with site specifics, policy context, and case officer.
