My Thai house has flimsy aluminum ceiling supports on a 600mm x 600mm grid. Climb a ladder, remove one tile and throw the wire over to near where you want it. Open tile at that point and continue. Easy.

The op obviously doesn't have that type of ceiling design but I too am confused as to what he does have. Mine is an alluminium grid system but without removable tiles but with plasterboard sheets and all the joints are taped and smoothed to it's a continuous ceiling. There is however an access trap and through there you can walk along the top of the internal walls or walk on the "C" section steel that spans the house and is welded to the roof "C" section steel. I was up in the loft last month putting cables in for extra outside lights and it was a doddle.

I have the same sort of plasterboard ceiling with taped joints as you, but the supports are made of thin steel instead of aluminium.

I can also walk along the wall tops or big steel roof C beams. Unfortunately, they don't go everywhere I need to, like over the consumer unit.

I'm almost finished, and hopefully will only need one more climb. So far have only cracked the bedroom ceiling when I slipped, so no need to replace roof panels ( yet ).

Make a trap door where you have cracked the ceiling. It would be a good patch up, good for future access and if done properly, they are hardly noticeable.

Good idea, thanks.
