Requirements for valid planning application

All planning applications require supporting documents and information. We often require accurate drawings and plans that clearly show your proposed development.

You can find out more if you need planning advice.

Mandatory application requirements

Location Plan, showing the location and boundaries of the site you are planning to work on and the site area in context:

  • based on an Ordnance Survey map at scale 1:1250 or 1:2500
  • show the surrounding land and buildings
  • mark the application site with a red line
  • mark any other nearby land you own with a blue line

Site Plan - this is a more detailed scale plan showing the relationship of the proposal to the site boundary and any buildings on neighbouring land.

You can use the Planning Portal's 'Buy a Plan' service to make sure that you meet our requirements.

Completed application form - check on the Planning Portal for the form that best fits your needs. There are National Validation Requirements and the following types of supporting may be required:
