How Watford decides solar, wind and battery applications

Watford has 3 decided solar, wind or battery applications in REPD — too few for a refusal rate (we show one from 10 decisions). Across all UK planning authorities 19% of 10,236 decisions were refusals.

All projects in Watford

Is the status up to date?

32% of applications still shown as pending in REPD were submitted more than two years ago, and only 37% of pending records were updated in the last 12 months, so some of them may already have been decided. Near WD18, 3 projects have a status that may be out of date (pending for over two years, or approved with a permission expiry date already passed). Check the council's planning register for the latest decision.
