Teams played matches within a series of divisions with the winners of the top division being crowned County Champions. Matches were played using a
one day format with 50 overs per side. The championship worked on a points system, with placings decided by
average points of completed games. Due to restructuring ahead of the
2012 season, which had divisions of nine teams compared to six in 2011, there was no relegation and more teams were promoted per division. The points are awarded as follows:
Win: 10 points + bonus points.
Tie: 5 points + bonus points.
Loss: Bonus points.
Abandoned or cancelled: Match not counted to average. Bonus points are awarded for various batting and bowling milestones. The bonus points for each match are retained if the match is completed. •
