Help with installation methods please.

[sjm]

Currently doing a rewire on an old house. Loft has 50mm joists at right angles to a large central joist 200mm. So I can clip cables along the centre of the loft with no problem. Using installation method 101 it would seem that I can lay the cables out to light fittings between the joists on top of the plasterboard ceiling. I'm using 1.5 T+E so insulation on top should not be a problem.
Normally I would fit extra runner boards to clip the cables to but I need to get the 1st fix done asap so the quickest allowable method is required. Your valued opinions would be greatly appreciated.


Thanks in advance.
Steve.

1.5mm will be fine under insulation on a 6A breaker. It only becomes difficult with ring finals, showers etc..
