To coincide with the return of community fundraising and face-to-face events, the Fundraising Regulator and the Chartered Institute of Fundraising have published joint new guidance on cash collections and events & community fundraising activities.
They bill it as a framework to aid good decision-making and I recommend you look at the updates to the Code of Fundraising Practice. A good starting point is the Fundraising Regulators press release, with links to specific areas of the Code.
