You dont need a licence to listen to the radio in the UK today .....

BUT

Any location or premises, outside of home, where music is played from clubs to concert halls, from discos to dentists’ waiting rooms and from trains to takeaways needs a MCPS/PRS Music Licence for the public performance of copyright music.

( see mcps / prs website for all the details )

 Essentially your MCPS/PRS licence pays the musicians whose tunes amuse you during your daily toil !!

Its totally unrelated to the TV / Radio licence fee
