Thanks welbeck, she has decided to not do leaflets for the reason you stated and as far as collecting cash in boxes, according to Government Guidance, as long as you get a local council licence and are honest about what you are collecting for, taking no expenses whatsoever, have at least two people counting and banking the funds, that seems to be the criteria.
We have also found out that you can collect money on private premises and have collection boxes in public houses with the owners permission.
