I think that it should be mentioned that it is now not very easy to establish if the premises that may have booked you or that you are arranging a gig at - is licensed to enable live music.

Under the old legislation you could ask for and obtain from the local authority a list of the premises that had PELs.

I made that equiry yesterday and found that the licensing section could not tell me which of the the Premises Licensed venues had entertainment permission. And of course each licence will be different. It may be possible for a licensee on the phone to tell you that their pub has obtained entertainment permission. But this may only enable them to provide a Regulated Entertainment like Indoor Sports - but not for live music.
