Amending an approved planning application
Making amendments to planning permission that has already been approved.
When planning permission is granted, development must take place in accordance with the permission and conditions attached to it, and with any associated legal agreements. However, new issues may arise after planning permission has been granted, which require amendments of the approved proposals.
Where these modifications are fundamental or substantial, under section 70 of the Town and Country Planning Act 1990, you will need to submit a new planning application.
Where these changes are less substantial, there are two types of amendment that can be proposed: non-material amendments and material amendments.
Non-material amendments
A non-material amendment to an approved scheme can be summarised as:
"an insignificant variation in a detail, or details, of an approved scheme which does not raise any new issues which would warrant the submission of a fresh planning application"
To apply for this, you need to complete and submit the form for 'non-material amendment'. Please return the completed form to us, accompanied by plan(s) clearly showing the proposed changes and the appropriate fee.
If you're not sure if your proposal will be accepted as a non-material amendment, please contact the Planning Service.
Material amendments
Where there is a relevant planning condition on an approved permission, it is possible to apply to either vary or remove conditions by a material amendment.
To apply for a Material Amendment, you need to complete and submit the form and checklist for 'removal or variation of condition (S73) following grant of planning permission'. You should also submit plan(s) clearly showing the proposed changes and the appropriate fee.
