What is Welwyn Hatfield's Gera Planning Approval Index?
Welwyn Hatfield scores 91/100 on the Gera Planning Approval Index, ranking #153 of 310 English local planning authorities. The Gera Planning Approval Index (GPAI) is computed transparently from two real MHCLG figures for each local planning authority: the percentage of planning decisions granted (weighted 70%) and the percentage of decisions delegated to planning officers (weighted 30%). GPAI = round(0.70 × granted% + 0.30 × delegated%), on a 0–100 scale. A higher score means an authority where applications are both more likely to be approved and more likely to be handled efficiently by officers rather than held for committee. It is a descriptive index of the published year-ending-December-2025 record, not a prediction of any individual application’s outcome.
How long does planning permission take?
Nationally, 90% of major applications were decided within 13 weeks or an agreed time, and 88% of minor applications within 8 weeks or an agreed time (MHCLG, July–September 2025). Per-authority speed varies; check your council directly.
