Our pre-school recently had to cancel plans for a fundraising pub quiz in the infant school hall as the costs were going to be prohibitive. On top of the hall rent, apparently we would have had to acquire an entertainment licence.
I wasn't involved in it but as a registered charity it seems daft that we would have to do that.
Blimey, does that mean that school discos are hit, too?? Apparently not if it's restricted to just the school's own attenders... but about younger siblings of children at the school, or the school fete each year, if they play any music?
This Herts page implies that school premises are exempt:
Since it's a license you get from the local authority I would phone the city or district council.
Oh, and get back here and tell me what you found out so I can tell my school PTA.
