Brunel (West London) is a campus uni too I do believe!
Roehampton is a campus uni.
I go there and it's pretty nice, but if you're set for ABC grades then it's probably best to go for somewhere with a better rep.
birmingham lovely academic campus + most accomodation on nearby separate campus (but within a vibrant city) = best of both worlds
If you want somewhere that's pretty cheap to live and with low entrance requirements, what about University of Ulster? English is offered at their Coleraine campus (UU is actually 4 separate campuses), with 260 points for straight English and 240 points for English with American Studies or history.
exeter is usually referenced as having the most attractive campus in the country.
I wanted exactly what you're after and found that in Loughborough. Everything is a max 20 mins walk (thats from one side of campus to the other) All halls, union, shops, take away, taxis, library, hairdressers, opticians, doctors, dentist, estate agents, supermarket, banks, restaurants etc are ALL on campus. Town is less than a half an hour walk away and has loadsa good shops if you wanna go (or go on the bus like we do if you're lazy) but you only need to go if you WANT too, not cause you HAVE too. Leicester and Nottingham are also a 10 mins train journey away (a bus of which goes to the station from campus) so you can always get to the big places if you're after a big shopping spree!
Birmingham defo, campus uni but like 10mins on the train from city centre and english at brum is wicked.
Notts Uni is definitely the nicest campus uni in the uk, its more like hogwarts in the trent building than a uni. Its ace.
Huddersfield is a campus uni, right in the middle of the town. The halls the uni want everyone to go to are 5 miles away like, but all of the uni itself is on one campus.
Chichester is a campus uni for undergrad. Halls are about 1 minute from the bar, food and lecture halls
Post grad courses for teaching are based in bognor on the other campus
University of Exeter:
The UK's most beautiful campus, just 15 minutes' walk from the city centre. A Registered Botanic Garden, the Streatham campus was described by The Times as the 'best-gardened campus in Britain' and by The Independent as having a 'sublime' setting.
