Frequently asked questions
What is the planning approval rate in Cornwall?
Across all application types, 95.5% of 4,512 applications decided in Cornwall since September 2021 were approved.
Do I need planning permission in Cornwall?
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 Cornwall?
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.
