Have you thought about a current account with e-savings? I've got a Nationwide Flexaccount,and transfer most of the balance from my current account into an e-savings account which currently pays 5.8% interest. When you need money to cover a cheque, for example, you can just transfer money back from the e savings to the current account. Transfers are done on-line very easily and happen instantly. It works brilliantly for me. There's no minimum deposit required.
