Edit: just seen this and thinking this may apply:
10. Private family events
PRS for Music does not make a charge for functions of a purely domestic or family nature, such as wedding receptions, christening parties or domestic birthday parties, when:
* Attendance of guests is by personal invitation only (except for staff, performers, etc.)
* The function is held in a privately-booked room, not at that time open to the general public
* There is no form of charge made for admission
* There is no financial gain to the function’s organiser or host (e.g. the person hiring the venue)
