We understand the need for Clubs to know if their application for promotion has been accepted or not and whether their promotion to Step 6 is officially confirmed, however, this process takes some time.
When deciding the Club Allocations, naturally, these have to be performed 'top-down' and so ordinarily the first set of Club Allocations that are released are the Step 1 to 4 allocations. These are shortly followed by the Step 5 & 6 allocations and then, finally, the Regional NLS Feeder League allocations.
An article detailing the Club Allocation process can be found here.
