When planning permission is granted it is specifically for the development described in the application and shown on the submitted drawings, as modified by any conditions. A variation from the permission may mean that the entire development is unauthorised. However it may be possible to make some non-material changes to an approved scheme.
Non-material amendments are minor adjustments which do not significantly alter the planning permission which has been granted or its impacts.
Alterations are unlikely to be considered non-material if they would:
To make a non-material variation to a planning permission you must submit revised plans, the appropriate form and the appropriate fee to us. We then have 28 days - or longer if agreed - to decide if the amendments are, or are not, material.
Please download the Non-material Amendments Checklist and Form (PDF) (opens in new window)
Please make sure your application includes the right information, or it will be judged as invalid.
For more details about when we need the information above, and what we expect, please see our guidance notes.
Top tip: if you are applying by post, please send three copies of all forms, plans and supporting information.
Our guidance notes form part of our validation checklists. They provide further details about what information we require with an application.
