There is a possibility that the church didn't pay for them but the government did, I think the government owns the cathedral and pays for it's up keep, and heating etc during the winter because it is a national historical landmark. The liberal Church of England probably still have church services their but I doubt hardly any body attends, but thousands of tourist visit these historical sites.
Now if only the characters like Aslan and the other good characters of Narnia could come alive and wage war against the evils of the Church of England that would be great.
