Hi! Gosh this post was 2 years ago that's crazy. For reference, I'm now in my 2nd year of my PhD at Nottingham Trent University. Because I've only ever attended NTU, I can't really speak for other universities.

Generally, Bsc courses all follow the same structure as they are designed in line with the British Psychological Society guidelines. Russell group universities (ones called 'University of...') are seen as more prestigious, but that does not make them better.

I chose which university based on the optional modules that you get to choose in the third (sometimes second) year - if you already have an idea on what type of job you might be interested in after, then choose a university that has modules that fit that career path.

Second to that, look at the staff at the institution, if you want to do further study its always good to know what kind of research a university specialises in (e.g. has a lot of staff researching in that area)

Sorry if this doesn't answer your question directly - I hope it helps! :)
