My Nana used to make bread pudding as opposed to bread and butter pud. The difference, in my mind anyway, was that B&B was individual slices of bread, buttered, with dried fruit on and custard poured over to set. My Nana's was stale bread bashed into crumbs, mixed with dried fruit and custard. It set in a way that you you could slice it but it was too soft to eat with your fingers - Always a spoon.
