Why did you change to a student account?

Id be very suprised if they HAD actually given you a 1k overdraft on a student account, but ive never had a student account so wouldnt really know anyway!

Halifax are wank though, just go to Natwest.

And yes, Natwest seem to just automatically up your overdraft for you.
When i was on an irregular income they wouldnt give me an overdraft at all.
I needed to buy a car a few years ago and a £1.5k cheque wasnt going to clear intime so they agreed to an overdraft to cover it. Since then its risen to over £2k. Think its about £2250 now.
