Suspending wires on ceiling?

[Vortigern]

I am about to start wiring two flats from scratch. The builder board the ceiling and make it fireproof my first fix will be to this ceiling. Then they suspend another ceiling under that by 150mm with accoustic/thermal so my wires will be inside that. I am planning to use metal plastic coated strip and loop them on the routes. The question being how do you do it, is there a better way?

Can't think of a better way and it is probably as good as any alternatives although a lot would depend on the construction of the suspended ceiling and any effect the acoustic / thermal insulation may have on the cable ratings

Hi @UNG, yes thinking about that. Is accoustic thermal (I guess so) and it is above plasterboard (100mm) then the cable touching plaster board on top of another layer of accoustic (100mm) Trying to figure out if that counts as "surrounded by thermal insulation" Assuming the worst anyway and using the rule of thumb applying a 0.5 downrating factor.
