The following guidance can help you assess whether Planning Permission is needed:

You can make certain types of minor changes to your house without applying for Planning Permission. This is called "permitted development"

Our Permitted Development Fact Sheet may answer whether works you are proposing fall within “permitted development”.

The Planning Portal’s interactive guide also provides guidance on whether the works you are proposing fall within “permitted development”: Planning Portal Permitted Development Guidance.

The following link is to where you can view an online version of the complete permitted development legislation - The Town and Country Planning (General Permitted Development) (England) Order 2015).

In some cases, some of the permitted development rights may have been removed by the issuing of an Article 4 direction. This will mean that a planning application will need to be submitted for work when it would normally not be required. For further information, please see our page on Article 4s

The Planning Portal website provides up-to-date information about work that can be carried out with and without planning permission.

This information is provided in an interactive guide: Do you need permission?

The Planning Portal also provides planning and building regulation guidance for many common building work projects for the home,: 

If you need planning permission, and would like advice on whether your proposal would be supported, you can use our pre-application advice service before submitting your application to us.

If after using the above links and guidance, you feel that Planning Permission isn't required for the works that you are proposing, but would like an informal view of whether you need Planning Permission, you may wish to use our: "Do I need planning consent or building regulations?" service.

This will check whether you need Planning Permission, Listed Building or Demolition in a Conservation Area Consent and/or Building Regulations. To use this service, please send us a completed Do I need planning consent or building regulations form.  We aim to respond within 10 working days.  The checking service is free for building regulations, but there is a fee of £50 (including VAT) to check whether you need planning consent.

For peace of mind, you can apply for a lawful development certificates if you wish. This is formal proof that your household building work is lawful and doesn’t require planning permission. There is a fee for this service.

If you are creating a new vehicle access or off-road parking space you may need to apply for Planning Permission, depending on the location and category of road.

Once planning consent has been granted, or you have confirmation that it’s not required, you need to apply for a Vehicle Crossover Licence for permission to cross the footway with a vehicle. There is a fee for the licence.
