If you wish to “perform music” in your hall, and that could be almost anything from a live performance to a radio playing in the background, then the hall will need to obtain an annual licence from two copyright collecting agencies – the PRS and PPL. For an explanation of the difference, how the fee is calculated and how to pay it, try the link here. How much your hall is expected to pay is related to its income. But remember this income does not include donations or grants. Both PRS and PPL charge 1% of the calculated income.  However, there is a minimum charge, regardless of income,  which is currently (May 2024) £162.00/year (including VAT) for the joint licence.
