The league will be divided into two divisions, with Competitive (Comp) and Recreational (Rec) divisions playing on alternate weeks.  All teams will have five weeks of regular-season play, with five games per day during a four – five hour period.  If we do not reach capacity, BSUK will amend the league format but will ensure teams play the maximum number of games possible.

There will be a scratch team at each week of the Comp and Rec divisions and individuals who wish join this team should contact

In the interests of fairness and to balance both the Comp and Rec divisions, BSUK reserves the right to make final decisions on which division teams will be assigned to.


Osterley Sports and Athletic Centre will host the majority of the league. Due to availability, some sessions will take place at Brentford Fountain Leisure Centre (this is noted on the dates below).
