Mid Sussex granted permission on 3 December 2025, subject to any conditions on the decision notice. Work must normally begin within three years or the permission lapses. More in our guide to what happens after a planning decision.

An amendment application makes limited changes to a permission that already exists; anything beyond modest adjustment needs a fresh application. More in our guide to planning application types.
