I'm not at Reading, but I don't think you'll come up against any hidden admin costs. If you start this year, fees should remain at the rate you started paying them throughout your course. That's the situation with undergrad courses. As for funding, I'm not an expert, but I would imagine that it is very difficult to acquire funding for the arts and humanities, particularly following recent cuts. You could look at the AHRC and see what that says, if you haven't already.
