Whatever the check is (I think Enhanced CRB is an old one) there are
certainly checks like that done on Uni students who are volunteers.
And apparently are still not transferable, and have to be done over
and over again for every few hours volunteering.

You're out of date. According to what I've been told, any organization
can accept an existing DBS check rather than doing its own. Obviously
it needs to consider the risks in doing so, and needs to do the
identity check.

Perhaps I identified the wrong failure mode. On second thoughts more
likely it's because at the application stage (to multiple organisations
for a summer of bits-and-pieces volunteering) the first DBS check hasn't
come through yet.
