My brief research suggests that a snooker hall would fall under the use Class E. However, if the premises is permitting access to non-members to frequent the bar, as an ancillary to the snooker use, would this therefore be seen as mixed use, and thus sui generis?
Furthermore is there a period of time that the premises could have been closed for to lose the class provision, including if it closed before 2020 when Class E was introduced?
Welcome advice.
