ouch, new opening at number 19 on the list. Although we do have teachers and other CRB screened people in our ranks so if one of them were to become the Club Welfare Officer you could extend the age range down a bit.
Unfortunately you'd still have to have another CRB check even if you were (for example) a teacher. The checks are organisation specific, and everyone who will be working (including temporary staff, volunteers, etc) with children would need to have the check done.
