Loose elecrtical wire

Ratsathome

Hi just want to find out about loose electrical wires.
I saw in my roof space loose electrical wires running to the lights and sockets.It is the ones with the extra grey insulation around it(not t+e) and as far as I know that is allowed.
I work at a company that outsourced all their electrical work. Today I noticed that they run the normal brown/blue and green loose inside the drywall. Is that allowed?
Thanks

Hard to tell but maybe looks like pvc only cabling in the pics
So no that's not allowed

Surface wiring would be better if that's a commercial type installation

I think a better definition picture would help.

They going to put drywall slabs over them.

This is not permitted. There’s no mechanical protection. Should be pvc/pvc or twin and earth. I don’t think it passes the minimum depth either. As another poster pointed out,a surface installation may be better

Needs to be another layer of insulation on those cables (looks like single pvc in the pics). If it was pvc/pvc the cables don't need any other protection behind a dry wall as long as the cable runs are run vertically or horizontally from each outlet or run at the top of the wall within 150mm of the ceiling.

Ouch. No mechanical insulation.

Was this work done by a qualified electrician? If so were they trained to Irish or equivalent standards? Who is responsible for signing off their work?
I wouldn't allow them to slab it if it's going to come back to your company to pay for it to be rectified later. Best to get it done properly before it goes any further.

Does any competent electrician even do that, I certainly never did

Imo anything concealed should be dropping to a point unless it's steel

That's just what the rules say
