Revisions and amendments to planning applications

Policy on accepting amendments to planning applications

The Council will exercise its discretion whether to request or accept amendments to a planning application under consideration.  Upon receipt of an application, we expect it to be:

  • supported by relevant information and
  • in a condition to be fully assessed and determined as submitted.

On that basis our normal position is not to seek or accept amendments after validation.  We emphasise this approach by encouraging all to engage in the pre-application service.

We will not accept unsolicited amendments.  Please do not seek amendments in response to an objection unless first cleared with your planning case officer.

Guidance on amendments

This guidance will help you understand when the Council will/will not request or accept amendments to planning applications.

Unless there are exceptional circumstances, we will only seek an amendment under either or both of these 2 conditions:

  1. Further analysis of the case means more information or clarification is needed.  It must be needed to complete the assessment of the scheme.  For example, cross sectional or levels details drawings;
  2. Amendments of a minor nature that would improve the scheme.  This must be a necessary improvement and not jeopardise a decision within the statutory period. For example, requiring additional consultation or more detailed third party expert advice.

We will:

  • help you consolidate minor changes ( that result in an improved scheme) into a single request
  • only accept one round of amendments to a submitted scheme.
  • only accept the amendment if an extension of time is agreed at the outset.

This means we will not generally accept amendments to planning applications if/for:

  1. they trigger the need for a fresh 21-day consultation (assessed on an individual basis)
  2. an increase in size of or material change to the red edge site boundary unless requested by the LPA
  3. a significant move or relocation of footprint and/or volume and mass of built form
  4. introduction of materially different uses
  5. conflict with development plan policies
  6. materially increase the visual impact of the development
  7. materially increase the amenity impact of the development on a feature of recognised sensitivity
  8. increase in the impact on a heritage asset
  9. exacerbate concerns raised by third parties.

This is not an exhaustive list.

Non-material amendments after decision

You can apply for a non-material amendment to an existing planning permission. Section 96A of the Town and Country Planning Act 1990 (amended by Planning Act 2008) covers this. You may need to make a change after the planning decision because:

  • Building Regulations require a change to the proposals
  • unplanned issues arise when construction or operations start.

Local Planning Authorities may allow small changes as 'non-material amendments'. The benefits are:

  • the applicant avoids the time and costs of making a new planning application
  • the Local Planning Authority can make the best use of its resources.

There will be no:

  • consultations
  • publicity and
  • notifications

because a non-material amendment is not an application for planning permission.

Non-material amendments must:

  • be within the scope of the original planning permission
  • not result in a materially different scheme that has a differing impact.

When a non-material amendment is accepted, it means that:

  • enforcement action will not be taken against the breach of planning control
  • there is an accurate record of the development as completed.

There is no statutory definition for 'non-material' changes.  It depends on the context and is determined by the Local Planning Authority.

Non-material amendment criteria

Each application will be considered on its merits.  The proposed change may be a non-material amendment if:

  1. There would be no change to the application site boundary and the proposal would be located within it (red line boundary)
  2. The amendment would not conflict with development plan policies or other Government guidance
  3. There would be no conflict with any conditions on the planning permission
  4. The proposal would not make worse any concerns raised by third parties when the original planning permission was considered
  5. The approved footprint/siting of the building will not be moved in any direction by more than 1 metre
  6. The proposal would not result in an extension to development already approved
  7. The height/volume of the building or extension would not be increased or significantly reduced
  8. The amendments must not result in a fundamental change in the design of the building
  9. The change does not amount to new works or elements which have not been considered by any environmental statement submitted with the original application
  10. Amendments to windows/doors/openings must not have any overlooking impact on neighbouring properties
  11. There would be no change to the description of development in respect of number of proposed units

These criteria are designed to prevent amendments being accepted that would have a harmful impact.  If the above cannot be met:

  • a Section 73 application or
  • a new full application may be required. 

Please consider whether the proposed change meets these criteria before making a submission.

A refused non material amendment application will not receive a refund. The development must be undertaken with the approved plans on the original application. Or you may wish to apply for a revised planning application.
