No not really.
As part of the join process they pay an admin “fee” that includes the cost of the Sqn polo top & the “subs” deposit.
You have to call it a subs deposits not a uniform deposit as otherwise if the uniform is not returned you would technically have to transfer the money to the RAF.
On leaving you just have a check list that for all the leaving actions including making sites subs are all paid up.
If everything’s in place raise a cheque or payment to the parent via cocoon for reimbursement.
Final step once EVERYTHING is done is discharge on bader.
Exceptions is Sqn transfer is they we refund the deposit as part of the transfer as every Sqn is different.
System is pretty good. We also do deferred leave (bit like NEP) where if a cadet is not sure (like changing schools or doing an event) we bag & seal their uniform up & hold it for three months.
If cadet comes back then we give them the bag back, if nothing heard we process the discharge.
