Volunteer What happens if I don’t pay my minimum donation? Challenge events and assignment donations have minimum amounts and you will be told when you get a place when this is due in. Non-payment can result in serious disruption to your place on the challenge or assignment team and you may forfeit your right to a place and be held responsible for any costs incurred by the charity. Any donations already given cannot be refunded if you cannot join the team. Please plan your fundraising and contact us in plenty of time prior to your deadline if you are struggling.
