LED drivers in Celotex with no space

[Dray]

Hi all.
So I have read a few posts on fitting down lights into celotex or equivalent and I have the same issue but with my own property, and my question is this. If I am going to install some LED downlights into a bathroom where 2/3 rds of the ceiling has no space due to celotex...can I extend the cable from the driver of each LED so that they can be installed/driven from the void that has the space to fit them? they will be accessible from the cutouts of the other downlights, and be extended about 1.5m.
T.I.A

Barking IMO to line a roof with Celotex then cut a load of holes in it. - I try to persuade customers not to, but I don't always succeed.

I sort of agree with you there Justin, but builders should then put a little thought into the design of the lighting...and not just hang a single pendant in a large bathroom just because it's easier for them. Had I done the extension/ refurb I would have done everything right at first fix stage rather than the usual FITWD attitude of most builders these days
