There will be no play-off if the club in Championship 2 has not received a licence for senior football. The five lowest ranked clubs will also be relegated from Championship 2 to regional football. However, if there is no eligible regional champion for promotion, only four clubs will be relegated with the 10th-placed club reprieved.Team changes
