A Development of National Significance (DNS) is a type of planning application for a large infrastructure project.  

The previous DNS Portal website was hosted by the Planning Inspectorate and contained information on:

  • proposed DNS cases
  • live cases 
  • cases that had already been determined

Developments of National Significance applications can be viewed on the ‘Planning casework’ portal.

Any representation submitted outside a consultation window is likely to be returned as late or unsolicited. If there is a live consultation, please submit your representation via e-mail, quoting the project title and new reference number in the subject line.
