Making changes to approved plans

If you already have planning permission but need to change your approved plans, this page explains what to do next. Some changes can be dealt with quickly, while others need a new planning application. We’ll help you understand the difference and how to apply.

Minor changes to approved plans

If your change is small, you may be able to apply for a non‑material variation. This is for changes that do not significantly affect the original permission.

We compare your proposed change with the approved plans to decide whether it is:

• non‑material – a small change with no significant impact
• material – a change that could affect neighbours, the appearance of the building or how the development works

Each request is considered on its own merits. Where it is considered a material change, a fresh revised planning application will be required.

Apply for a non‑material variation

You can apply online using our form.

Each request is charged at £247. Payment must be made when you apply, so please have your card details ready

No neighbour notification is required, and we aim to issue a decision within 21 days of receiving your application.
