The T20 Trophy groups have been changed with one team moving from each group as the Match Secretary refreshes the groupings whilst keeping a regional aspect to these early heat matches. Included are the two teams promoted into the Premiership; Thongsbridge and Moorlands with the two teams relegated from last season's Premiership; Elland and Shelley. However the previous year's relegated teams Slaithwaite and Holmfirth will now take part in the T20 Shield.
