Developments of National Significance

Planning applications for Developments of National Significance are examined by the Planning Inspectorate who also make a recommendation to Welsh Ministers, who in turn decide whether or not to grant permission for the scheme. We are a ‘specialist consultee’ in the processes for determining Developments of National Significance

We have produced new guidance which sets out our role as a specialist consultee for Developments of National Significance (DNS).

This guidance sets out how and when to consult us during the application process. 

The table attached below sets out the determination period for consents for which we are the consenting body.

If your scheme needs one or more consents for which we are the consenting body, please refer to the table. It will guide you when to submit the application, so that it can be decided within a similar timescale as the planning application for your DNS.
