Planning application supporting information

You are likely to need to submit extra information with your planning application. This is known as validation criteria. If you do not submit all the correct information with your application it may take longer for you to get permission.

All supporting documents should be uploaded to the Planning Portal alongside your application. All plans and drawings must include the paper size, address of the proposal, metric scale, be appropriately titled, and plans must show the direction of north.

Please ensure the content and detail of your supporting documentation is sufficient to assess and consult on your application. Many applications require further information following validation due to insufficient detail within documents. This can extend the timeframe required to make a decision on your application.

Validation checklists

Please select the appropriate validation checklist for your application type below. Our validation checklists can also be accessed via the Planning Portal.

Householder application

Householder planning applications provide a simplified process for proposals to alter or enlarge a single house (but not a flat), including works within the boundary/garden. This is commonly used if you are a homeowner wishing to complete work on your home.

Full application

A full planning application is required when making detailed proposals for developments which are not covered by a householder application or permitted development rights. This is commonly the case for new buildings of any kind and any 'commercial' property.

Biodiversity requirement

Our biodiversity requirement asks an applicant to submit a self-assessment form as part of their supporting documentation. Please check the associated validation checklist to see if this is required. If you do not provide a self-assessment when submitting your application, it is likely the application will be invalid.

Mandatory Biodiversity Net Gain (BNG)

For further information on BNG, including Gloucestershire-wide guidance please see our webpage on Biodiversity Net Gain.

Non-material amendment

Once you have been given planning permission you may need to make a change to your application. If so, you may need to apply for a non-material amendment.

For some adverts you will need to get consent. The validation checklist tells you what additional information you will need to include with your application.

You can apply for a lawful development certificate when you do not need planning permission to prove that your development is legal.

Check what extra information you need to submit to get a lawful development certificate.

Listed building consent

If your building is listed you will need to get consent for changes or demolition.

Outline planning permission with reserved matters

Outline planning permission gives agreement for how a site could be developed. The permission is given as long as an application for approval of certain conditions, called Reserved Matters, is submitted.

Prior approval

You may need to let us know about work that does not need planning permission by applying for prior approval. You will not be able to start the work until we have agreed.

The following validation checklist for prior notification is available:
