If the aspect of English literature you're interested in is creative writing, have a look at UEA. Their courses have notched up an impressive string of success stories, not least Ian McEwen. (But maybe they're only post-grad courses.)

Keep in mind that whether you like somewhere will be as much to do with you as with the place. Sheffield could indeed be a good bet, but Nottingham and especially Leeds are really humming these days, so give them serious consideration. Similarly Edinburgh, which would make Greg very happy as it's a touch more west than Bristol.
