⚠️ Data limitations on this profile. Of 13 decisions, 1 (8%) have outcomes that couldn't be cleanly classified as approved or refused (e.g. "decided", "advice given", non-material amendments). The approval rate below is calculated from only the 12 clearly approved/refused decisions.

Known data gaps: our Idox scrape covers Gateshead, Sunderland, and Northumberland from late 2023 onwards. Newcastle Upon Tyne data is NOT in our corpus (the council's planning portal blocks IONOS shared-hosting IPs). If you're looking for a Newcastle case officer, their decisions won't appear here even if the officer name matches.

📡 Data Pipeline

Officer intelligence is generated from planning application decision data. As more authorities are ingested into PlanningCore, officer profiles become richer and more accurate.

📊 Data sources & freshness

planning_applications.case_officer (updated Daily ingest)
Live ingest from LPA portals (Idox + Civica + Northgate). Coverage varies by council — leading LPAs publish on every record, others publish only on committee reports.
Approval rate calculation
approvals / (approvals + refusals) per officer. Withdrawn and pending applications are excluded.
Date window
Stats reflect the entire decision history for the officer, not a rolling window. Recent volume changes can shift the averages.
