Source: Renewable Energy Planning Database (REPD), Department for Energy Security and Net Zero, Open Government Licence v3.0 — 2026 Q1 extract. Approval rate is over decided applications only (approved ÷ approved+refused); withdrawn and undecided schemes are excluded. A permission later expired still counts as approved because consent was granted. REPD covers schemes of roughly 150 kW and above, is published quarterly, and does not record refusal reasons — so nothing here explains why a scheme was refused.
