English degrees can vary hugely in quality. Your DD needs to delve into the Departmental website. NOT the one which advertises the courses for UCAS applications, but the actual information used each day by the Department. I generally find that these are very difficult to locate for post-92 universities; the better ones are much easier to find.
In my experience (from teaching EngLit over 25 years) the better the research rating for a Department, the more demanding the course will be. The better the A levels of the applicant, the better the course she can aim for. I think EngLit is one subject where the REF is really significant for standards of teaching and the ambitions of staff for students. It's a subject where all teaching staff (including part-time tutors and graduate teaching assistants) need to be at the cutting edge of their subject. Otherwise it can be pretty mediocre teaching & students aren't taught with ambitions to generate their own knowledge, or take intellectual risks, because the staff don't generally know how to, or aren't given the opportunities to do so (ie no research leave).
In an excellent Department, the thing you can be pretty sure of is that in each of the 3 years you'll be taught by people writing the books that you'll need to read - that is, further reading & reseaerch for your essays. So I'd be looking for a combination of good teaching ratings with a good REF result.
I'd also be looking at what the academic staff have published - books with good university presses (eg Cambridge University Press, Oxford UP, Routledge, Palgrave Macmillan), not just "Gave a conference paper on XYZ 2 years ago."
I'd also be looking at what the Department website says about PhD students. Are they present on the website? Is there information about their research? What topics are they writing & researching? A good PhD culture means a good teaching culture, and in my experience, PhD students in EngLit can make fantastic tutors for undergraduates (I did it myself!) They're usually younger, closer to the undergrads' experiences, and usually very enthusiastic about teaching & engaging with the undergrads in small group teaching. It's not a bad thing to be taught by a PhD student in EngLit, in conjunction with permanent staff of course! In EngLit, good communication skills are now an important part of what we look for in selecting staff - there really are very few "absent-minded professor" types left in the sector in this discipline.
Don't set your heart on particular modules. Most Departments circulate and rotate optional modules over the years of a degree. I'm about to be on leave, so the 3rd year module I usually teach will be rested for a year. It won't be taught by anyone else, as it's based on the work from my last but one book, so it's truly "research-led teaching."
But do look at the core compulsory modules across 1st to 3rd years. Think about the coverage of literature. The degree course I taught throughout my PhD had a huge First Year survey course from 16th century poetry to late 20C fiction - great fun to teach, and really stretched the undergrads coming from the very piecemeal approach of their A levels (even 20 years ago). Lots of reading: the equivalent of a novel a week. You need to like reading and want to read to do a course like that.
As for publishing - as others have said, an EngLit degree is not an automatic route to publishing: your DD is as likely to be just as successful with a History degree. It'll be a LOT about ambition, and sensible extra-curricular activity: get involved with the student newspaper, write for it, edit it, get internships and work experience in the publication industry, and don't be snobbish if it's in Marketing (the main Commissioning Editor I work with at my publishers started as a marketing assistant).
I did both a History degree and an English degree (Double rather than Combined Hons) - loved them both, although English was far easier. But they go well together as a Combined programme, so your DD could look for a combined Hons degree.
I think that if you have the choice of the best English departments by dint of 3 A to A* at A2, then the choices may be about type of university: city, green fields, country, etc etc
