Under UK copyright law, schools, colleges, universities and PTA's wishing to play a film in public will generally require a licence from the copyright owner or its representatives before doing so. 'In public’ means, broadly speaking, to an audience outside of the home. If that educational institution does not obtain the required licence they risk infringing copyright.
A PVSL is required when films are screened for the benefit of Film Clubs, Breakfast Clubs, End of Term Treats, Wet Weather Screenings and After School Clubs*.
