Hope you don't mind me jumping in on this one!
To clarify - if your bank is a creditor you will need to open a new account with a bank who is not one of your creditors. Depending on your credit score at the time of opening an account you make get a full bank account rather than a basic one. The only stipulation is that you must not have credit with the account.
If your bank is not a creditor you will most likely be able to keep the account, although again you must not have any credit. Some banks have a policy of closing the accounts of people in an IVA - HSBC and First Direct definitely do this as company policy, and I have read on here that Natwest have done it, although it doesn't seem to be company policy.
Yesterday is history, tomorrow is a mystery, today is the present - a gift to make the most of.
