Grief guys!
Answer as previously given.
In terms of reloads, BASC are better responding to clarify the situation. But I would imagine you could take a selection from - Insurance Requirement, Risk Assessment Issue, Club / Range rules - very much doubt its just for the sake of being awkward.
As others have pointed out, the requirement to be a member of BASC is applicable only to courses/ Assessment taken direct through BASC - there are other providers, even ones operating through BASC as an Assessment Centre that do not have such a requirement.
If you choose to breach the requirements of any Assessment Centre, your Assessment is liable to be void. I've not come across any rules/ requirements yet that are just made up for the sake of it - with any provider. A person may not understand the reasoning, but like as not there will be one.
Each provider is a bit different, thats a strength and offers wider choice. Its why I try to encourage people that post on SD about doing DSC1 to elaborate ( after the event ) on how they personally found it. Honest ( unbribed! ) reporting - I believe - provides a great service to others and a much better source than own trumpet ( I'm half deaf so always out of key anyway

) blowing by any of the providers postings.
