In answer to the many disagreements of my comment, of course if as the OP states which, in all honesty I missed, that the ceilings were coming down then in this case I would agree with the majority do it from below.
One question to the OP, he says he want's the thin chipboard ceiling down.
OP is, or does the rewire include every thing in the house, or is it just in one area for example the Kitchen area? will all the ceiling material be removed from the entire property?
That's right - I'm having the ceilings of the entire house plasterboarded to remove a thin chipboard - potentially leaving the hallway / stairs. There will new wiring to add more sockets and spotlights throughout. The current kitchen area is included / the future kitchen will be in an extension.
