I spoke to my accountant about having a business account at the bank. He told me why would I need one ?. As long as you can show your income and your expenditure to the tax man, You don't need one. All Mr Taxman wants to see in what comes in and what goes out.
So I just use a standard bank account with all payments going into that and I list any withdrawals I make daily ending it each month using windows office data base.
