Scoping: NESO is not aware that a planning application has been made.

Awaiting Consents: NESO is aware, or the customer has told it, that a planning application has been made.

Consents Approved: NESO is aware, or the customer has told it, that the planning application has been approved.

Terminated: used by NESO only in its register of 30 April 2021, for two projects that left the register the next month.

These statuses are NESO’s, not QueueWatch’s, and NESO describes them as “as far as we are aware”, so a project may be further along than its status shows.
