Re fittings, I'd ask the seller whether cupboards, cabinets, wall lights, etc. will be sold with the house or removed. If they are to stay with the house, get it put in writing. I've even seen places where the outgoing owner has taken fancy brass light switches and sockets off the wall and not even fitted cheap white replacements, just left the wires hanging out!
Check the deeds to see if any rights-of-way exist over your land. People have bought a place with grand ideas about how to build extensions, patios, etc. only to discover later that they can't do any of them because there's a right-of-way running right past the side of the house.
Check also for any convenants on what you may or may not do. This is more likely to apply to a modern estate house than an older property. Some have restrictive clauses about the maximum height of any hedge or trees, how many vehicles may be kept on the driveway, and so on.
If the house is a semi-detached (= U.S. duplex) or a terraced (row) house, check who has responsibility for party walls and any other shared areas.
I know some people will disagree with my next point, but if you are in any way planning on buying a place to "fix up," alter, or extend, I wouldn't touch a listed building with a 10-foot pole. There are enough planning/building regulations as it is without getting involved with listed-building consents.
A general building survey does not normally include an inspection of electrical wiring, plumbing, or heating systems. If you're not able to examine them and determine their condition and safety for yourself, you might want to arrange for independent inspections. For the electrics, you want to ask for a PIR, or "Periodic Inspection Report."
