I am on the management committee of a community hall, which has an adjoining parking facility for hall users. Unfortunately this is not a closed area and is regularly used by local people who used the adjacent bowling club. We would like to develop a differential charging policy for both hall users and non hall users partly to generate some income, but also to resolve some of the disquiet this parking issues causes. The hall is governed by a deed of trust and there seems to be nothing within that deed to prevent us developing such a charging policy. Can you please advise.
