Poker in a Club (Private Members Club) Poker can be played in clubs as long as it takes account of the conditions that apply to gaming in clubs, including limits on stakes and prizes.
The maximum stake per player is £10 per game, and the combined stakes for your premises must not exceed £250 per day and £1,000 per week.
The maximum prize is £250 per game.
A maximum participation fee of £1 per person per day can be charged by a members’ club, with or without a club machine permit. A commercial club with a club machine permit can charge £3 per person per day, but only £1 otherwise.
Private Cash PokerPrivate Cash Poker (as opposed to tournaments) is allowed but Gaming is only private if it occurs in a place to which the public does not have access (normally a private dwelling, hostel, hall of residnece or similar establishment). No charge may be made for participation in private gaming (and this includes an entrance fee or other charge for admission), nor may any amounts be deducted from stakes or prizes. No profits can be made from private gaming, irrespective of how the organiser intends to use those profits.
Private gaming can potentially take place on commercial premises in circumstances where a members’ club hires a room in, for example, a pub or hotel for a private function where equal chance gaming only is played. However, organisers would need to scrutinise very carefully the arrangements put in place to make sure that the particular area of the pub, hotel or other venue in which the gaming takes place is not, on the occasion of the private function, a place to which the public have access and that those participating are not selected by a process which means that, in fact, they are members of the public rather than members of the club. The law in this area is complex and organisers are strongly advised to seek their own legal advice before organising events of this nature.
