A PPL licence is required when recorded music, within PPL's repertoire, including radio and television, is played in public. There is no statutory definition of "playing in public" and "public performance" but the UK courts have given guidance on its meaning and ruled that it means any playing of music outside of a domestic setting, for example at a workplace, public event or in the course of any business activities. No licence is required for listening on headphones. The playing of recorded music as part of domestic home life, or when the audience consists entirely of friends and/or family does not require a PPL licence.
