I'd go for an account like intelligent finance (part of the halifax) or virgin money, that's assuming of course you want to move the mortgage as well. Both accounts are offset, which means spare money in the account will reduce interest on the mortgage and maybe - just maybe because I'm not sure it;s still done - with the IF account the amount you can borrow on the mortgage has a reserve limit. Put another way, say your mortgage is 100,000 but the value of your property is 150,000, - and depending what you earn too of course - they will apply a limit on the mortgage which exceeds the balance now, so in theory, you could wip out that loan.
