I don't know much about philosophy, but the Religious Studies Department is very good and has a good reputation, especially for comparative and non-Christian religions. It is quite "cutting edge", so don't look at Lancs if you want conventional theology or Bible Study. They do a lot of religion and society, anthropological and cultural stuff.
I did RS as a minor, my tutor was of the Bah'ai faith, which helped me learn about something I had never even heard of!
The downside is that it is a small department, not many people study RS, and you will find that they are not able to offer all the modules every year, so you can be disappointed if the subject that interests you is removed for your year, because the content changes or the tutor goes off to do research or whatever.
