Hi, all... hoping for some pointers here since it seems to be a
minefield of confusing insulation.
I'm having a re-roof. Building regs. say I've got to increase my loft
insulation (currently zero) to the 280mm recommendation.

I am also in eth position of adding 280mm of insulation to a bare
loft. I can run the lighting wiring above the insulation; there is
enough slack. But this still leaves the 280mm of cable that is
completely enclosed in insulation. Is that acceptable? the wiring
has just been done.

Also, are you required to uprate the loft insulation just becuase you
are reroofing, or is it voluntary? It might be important if you want
to use the aded insulation as mitigation to some other work in the
house that reduces the thermal insulation. You can only play the
"improved loft insulation" card once. In my case I am delaying teh
loft insulation until we do the kitchen extension in case I want to
use it in mitigation for putting more than the standard amount of
window in the extension.
