[IP2]

I opened a Business account with Barclays when under 18, that however was quite a few years back.

Without directly asking your age, bare in mind that in October all Directors will need to be over 16 (This is already the case in Scotland).

As you are not looking for credit, dealing with suppliers should be less of a problem.

However one way to resolve the whole problem may be to appoint another Director/ Company Secretary that is over 18.

Good luck.
