Do I need planning permission?

Do I need planning permission?

You'll probably need planning permission if you want to build something new, make a major change to your building or change the use of a building. 

We've created an interactive online form that gives detailed guidance on whether or not you will need planning permission for a wide range of projects - from a rear extension through to a loft conversion.

It also gives guidance on what you need to think about if you want to carry out works to a property in a conservation area, an area with an Article 4 Direction or a listed building.

Get further advice

If you can't find the answer you are looking for, or want our team to look at your plans and give more detailed advice, we can help. 

If you have a general enquiry (not related to specific plans), why not submit a planning enquiry which costs £90 (inc. vat) and our team will get back to you within three working days.

If you want our team to look at your plans and give advice on whether or not they are likely to get planning permission, why not submit a pre-application which start at just £75.60 (inc. vat) for householders.

Don't forget about building control advice

Whether or not you need planning permission, you will still need building control advice to ensure your build meets required building control regulations.

Further guidance

The Planning Portal's guidance for householders is designed to help you understand what needs planning permission. It also has guidance on planning and building regulations for a list of common development projects.
