Sometimes, you may want to make changes to a proposal which already has planning permission.
This may be some time after the original planning permission was granted, given that permissions last at least three years from the date of the original decision.
Minor amendments and non-material amendments
Minor changes to approved plans can be dealt with under an amended plan procedure.
You should complete an application for an amendment – Planning Portal.
Make sure you read the validation checklist, as this explains in full what information is required when submitting this application.
Amendment fees
The fee is £44 if the application is a householder application. In all other cases the fee is £298.
In most cases, we’ll accept minor amendments including:
- a reduction in the volume or size of the building or extension
- a reduction in the height of the building or extension
- amendments to windows, doors or openings that will not have any impact on neighbouring properties
Examples where you will need to submit a new application
Some amendments will take a development beyond the scope of the permission. In these instances you have to submit a new planning application.
Examples include:
- a significant increase in the volume of the building or extension
- a significant increase in the height of the building or extension
- changes which would conflict with a condition on the original approval
- additional and/or repositioned windows, doors or openings that will have an impact on neighbouring properties
- changes altering the description of development from the original application
- amendments warranting re-consultation of neighbours, council departments or statutory bodies
