I suggest you look at the specific English Lit degree (+ modules) at the uni you're planning to apply to. It's a great degree if you're passionate about it. Just make sure you get a decent amount of work experience during your degree; it's extra important for Arts grads.
Edit: a bit of general info: be prepared to read tons of books, do background reading, spend many hours working independently, write tons of essays, proof read, analyse texts in detail, use/find numerous secondary sources, and so on. Source: I'm a Comparative Lit grad.
