Frequently asked questions
What is the planning approval rate in Isles of Scilly?
Across all application types, 95.2% of 434 applications decided in Isles of Scilly since August 2021 were approved.
Do I need planning permission in Isles of Scilly?
It depends on the project and the property. Many home projects fall under permitted development rights, but constraints such as conservation areas, listed buildings and Article 4 directions change what needs permission at a specific address. See our guides to permitted development rights and Article 4 directions.
Do I need a planning consultant in Isles of Scilly?
Many home projects do not need one. A straightforward extension on an unconstrained property is often handled directly with the council, or with an architect or agent preparing the drawings. A consultant is more likely to earn their fee where the site is constrained, the council has refused similar schemes, or an appeal is in prospect. Understanding your property's constraints and the council's recent decisions first makes any conversation with a professional a better-informed one.
