Planning Application Amendment Service
Amendments to Planning Applications
If you make changes to your planning application after submitting it, your case officer must:
- Review the new plans and documents
- Where appropriate, carry out further internal and public consultation
- Reassess your proposed development against planning policy
- Update their officer report
Going through this process means it will take longer to determine your application. Typically, it adds between 14 and 35 days to the assessment period.
Amendment Charges
From 1 May 2026, charges will apply for making amendments to planning applications after they have been submitted. The charges will cover the additional time and work required to review and process your changes, ensuring that resources are used fairly and that applications can continue to be processed efficiently.
The charges vary according to the type of application, as set out below.
| Development Type | Fee (including VAT at 20%) |
|---|---|
| Householder | £216 |
| Minor | £360 |
| Major | £720 |
| Advertisement | £180 |
| Lawful Development Certificate | £108 |
| Conditions (householder) | £60 |
| Conditions (other) | £180 |
The charges above cover one set of amendments only. Subsequent amendments will incur additional charges.
Eligibility
The amendment service applies to all applications for planning permission, except for Fast Track applications. It also applies to applications for lawful development certificates, approval of details reserved by conditions, and express advertisement consent. Amendments will not be accepted for other types of applications.
You can use the amendment service if you have been advised by your case officer to make an amendment to your application. However, you should note that case officers are not obliged to seek amendments, and unacceptable applications may be refused without advance notice.
If you wish to make an amendment without having been advised to do so by your case officer, you may be eligible for the amendment service, but this will be at the sole discretion of your case officer. Case officers will not accept amendments where:
- The development is considered to be acceptable and the amendment would harm the likelihood of planning permission be granted.
- The development is considered to be unacceptable and the amendment would not improve the likelihood of planning permission be granted.
- The amended development would be of a substantially different character or description to the one originally submitted.
- The application type is not eligible for the service.
- You are unwilling to agree to an extension of time or the required extension of time would be excessively long.
- The amendment has not been agreed with the case officer in advance.
How to use the Service
In all cases, the first step in using the service is to discuss the proposed amendment with your case officer by email. Their email address will have been provided to you when your application was validated.
You must discuss the amendment with your case officer even if the amendment is being sought in response to the advice of a third-party consultee or the comments of another interested party.
When the amendment has been agreed in principle with your case officer, you should prepare the plans and documents necessary to support it. Your case officer will advise you on what is required upon request. They will also advise you of the charge for using the service.
When the amended plans and documents have been prepared, you should send them to your case officer by email. Your case officer will then ask you to agree to a new deadline for determining your application (typically 14 to 35 days beyond the original deadline).
You will then need to pay the applicable charge, we will contact you about making payment.
Once the payment has been made, your case officer will process the amendment and begin the assessment process.
Exemptions
Charges will not be payable where applications are declared invalid at the point of submission and the amendments are made for the sole purpose of making the application valid.
Charges will also not payable where the application is solely for the purpose of providing means of access for disabled persons or other facilities designed to secure their greater safety, health or comfort.
Charges may be waived where the proposal was discussed under our pre-application service and officers’ advice was demonstrably followed. Charges will still apply in instances where pre-application advice was not followed.
