If you're looking for additional bursaries, you might be out of luck depending on your postcode, so maybe check if you'd be eligible for any additional bursaries/academic scholarships before deciding on a university. If you are, then you will be fine in an expensive city, but if you're not, then I'd suggest looking for a university that has relatively cheap accommodation and cost of living.
I got the maximum maintenance loan and grant, but was not eligible for any bursaries because of my postcode... even though I fit every other criteria needed. So just watch out for that!
