Hello there! Try HSBC - they let me open an international account and now I'm over here they have let me keep my UK account too on the same basis. I can do online transfers between the two and its worked well for me so far. ( I was an HSBC customer anyway but I'm, sure even if you're not, its worth opening a UK account and going this route.) Can't say I've seen any other International banks over here - all the others seem to be Canadian based, so might well be the only option!
Best of Luck :)
