The only change for the 2018 competition from 2017 is the quarter-finals stage is renamed as the play-offs.

Knockout stage
The winner of each group progressed straight to the semi-finals with the second and third placed teams playing a play-off match against a team from the other group which made up the play-offs. The winner of each play-off played one of the group winners in the semi-finals. The final took place at Lord's on 30 June 2018, with Hampshire defeating Kent Spitfires by 61 runs.
