By all means correct me if I am wrong, but isn't the NPPL(A) going to disappear next year to be replaced by the LAPL?
Given the OP is 15, surely tuere wont be an NPPL(A) for him to pass, but most likely an LAPL which would give access all over europe.
I know the details of the LAPL are still to be confirmed, but isn't that the intention?
