Each team must be based at a licensed pub or club, with at least one regulation dart board and an accompanying fixed oche (which may be detachable) with good lighting. The scoreboard may be chalk/whiteboard or electronic, and must be capable of displaying at least the most recent 4 scores for each side.
Teams may comprise as many members as desired (as long as they’re registered in the usual way).
The entry fee per team is generally around £60/year, however this may be changed/waived each year as per committee vote at the AGM. Once the fee has been paid it becomes non-refundable (eg if a team leaves the league).
