Im Cambridgeshire. Our nursery is £36 including meals for my 3 year old (little bit more for younger children) My childminder/daycare is £53 including meals. Both open 7.30 and CM finishes 6pm whereas nursery at 6.30pm. Neither provide nappies (although they do have emergency stashes) or wipes.
Agree that it really depends where you are and what type of child care you're looking for. I think nurseries tend to be more expensive than childminders, nannies more expensive than nurseries. Even in a relatively small area, nursery prices can vary massively. I pay £835 per month for a 3 day / week place (NW), think childminders are around £5/6 per hour (more if you just want after school rather than full days etc), nannies are £8-10 per hour net (but you have to factor in tax and NI on top of that).
