Why not open a current account with them just to for the internet banking option. Thats what I did with Ulster bank. I declined the ATM card and just use it to look at the balance. Every now and then I use the current account to pay off my credit card bill i.,e electronic transfer from my "real" current account to the Ulster bank account. Becasue I have no cards it doesn't cost be a penny in tersm of stamp duty and its free banking anyway.
I also have a Halifax credit card and current account but you can only view your baalnce online.
From my experience of the two:
not being able to view online transactions is a pain with halifax,
but they offered me a very reasonable credit limit compared with Ulster bank. Who in my opinion were ultra cautious when giving me a credit limit.
