I suggest calling your bank and ask them about it. If they allow crypto currencies trades, you should be fine and I believe there is in the UK a bank called Fidor which is crypto friendly.
Thanks, I spoke to my Bank who would not give a yes or no answer. They said they cannot give prior approval and all I could do was try a few transactions.
Of course this is not any use, I cannot risk having a large amount of money frozen in some dispute which may take ages to resolve if ever.
