Planning permission in Swindon

When you need planning permission

You usually need permission for: new buildings, major extensions, changes of use (e.g. house to office), work on listed buildings, and alterations in conservation areas. Smaller extensions, loft conversions, and some outbuildings may fall under permitted development – meaning no application is needed, provided you meet the rules.

Permitted development

Permitted development rights allow certain home improvements without full planning permission. Limits apply to size, height, and position. If your property is listed or in a conservation area, permitted development may be restricted. Check the GOV.UK guidance and, if unsure, apply for a Lawful Development Certificate to confirm your project is permitted.

How to apply

Submit applications to Swindon Borough Council. You can apply online via the Planning Portal. You will need plans, a location plan, and sometimes a design and access statement. Fees apply. Decisions typically take 8–13 weeks for standard applications.

Pre-application advice

Swindon Borough Council may offer pre-application advice for a fee. This can help clarify whether you need permission and what the council is likely to accept. See the council's planning pages for details.

Appeals and objections

If your application is refused, you can appeal to the Planning Inspectorate. Neighbours and others can comment on applications during the consultation period – the council publishes applications online.
