Frequently asked questions

What is the planning approval rate in Lambeth?

Across all application types, 80.5% of 4,647 applications decided in Lambeth since January 2023 were approved.

Do I need planning permission in Lambeth?

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 Lambeth?

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.
