I know NOTHING about British Universities but here's some info that I found... I recommend you visit this site:
University guide 2012: Law | Education | guardian.co.uk
You can get an idea of the names and research accordingly to where you have an opportunity of being accepted.
Also try to Google Research Assessment Exercise (RAE) or go here to view the pdf: RAE 2008 : Publications : 2008 : RAE 01/2008 - RAE 2008: the outcome
. This seems like an agency that reviews schools of all levels.
There must be a Princeton Review type site for Britain. I don't think its bad to ask if there happens to be any visitors that are British or studied over there. But yea it's going to be tough to find such person on a basketball forum for a Canadian team. You should signup for a Manchester United forum and those guys would have a better idea lol.
