A PPL licence is required when recorded music, including radio and TV, is played in public. There is no statutory definition of 'playing in public' (also sometimes referred to as 'public performance') but the UK courts have given guidance on its meaning and ruled that it is any playing of music outside of a domestic setting – so, for example, playing recorded music at a workplace, public event or in the course of any business activities is considered to be 'playing in public'. In contrast, any recorded music being played as part of domestic home life or when there is an audience entirely comprised of friends and/or family (such as at a private family party) does not require a PPL licence.
