Small changes can be made to approved planning applications without needing to go through the full planning application process again.
These small changes are called ‘non-material amendments’.
Non-material amendments must keep within the scope of the original planning permission and must not result in a totally different proposal.
In deciding your application we will use the criteria below.
If a proposed amendment involves any of the following we will not accept it as non-material:
Only someone with a legal interest in the land affected can apply for a non-material amendment. Examples of a legal interest include owning the freehold or a leasehold with at least seven years remaining.
If the application is made by anyone other than the owner, the owner must be notified of the application in the way the form explains.
