As far as loans go - best to have a search on the wannabes forum - it has come up there before.
Off the top of my head, if you're going with one of the well known integrated outfits in the UK (like OAT) they can help with financing and which bank to approach. I think HSBC were one who did a professional career type loan, but I may be wrong.
To be honest - phone a couple of the schools up - tell them you're planning going integrated in 2-3 years time at the earliest and if they have any advice on financing the course - I'd expect they'd have the best advice!
(But ALWAYS seek an approved financial advisors opinion - they are usually free - they make money of commission, so use them in case there are any pitfalls).
