1st flats with concrete ceilings

8mm hole and bang these in. Cable Ties Online | Masonry Mounts - https://www.cableties-online.co.uk/category.php?ID=8

If you have to support the cables in case of premature collapse in the event of a fire then use a bit of band strapping every so often in combination with the above.

Using basket etc will not make you competitive at all.

Depends upon where sockets are etc when I did some flats with concrete slab above clipped most of the ring around the perimeter on the wall above the ceiling. The main spine of wiring as Lee posted.

I've used p-clips and metal cable ties on jobs in past. Depending on size of void you'd probably need to work out if any pipe work / ducting going in same gap and try and keep your routes away from them. I've burnt through a ---- ton of sds bits doing concrete ceilings as well

Spit gun/Hiti gun, a lot quicker then drilling a hole and knocking in a cable hook, also a lot quicker then throwing up some basket as by time ducting and plumbers pipes gone in there would be hardly any room anyway.

Do you need to use metal clips,does the ceiling count as a barrier,I dint think so according to 18th.
We are going all the way back to the days of metal trunking/conduit,not a bad thing.

17th Edition says you need to metal clip exit routes, 18th says everywhere.

So crampets will be the job then

You would have a hard job banging crampets in to a reinforced concrete ceiling imo.

How many layers of plasterboard are going up?
How about metal cable ties every third fixing?

Sorry to invade this post. Just a variance on the above... same situation apart from the plasterboard ceiling is up plastered and painted in a relatively new apartment. Customer wants light switch moved to opposite side of room as it’s currently in a silly place. 6m across room assuming it directly opposite. What do other people do to meet regs in this situation? Metal fixings and a load of large holes cut out the ceiling? It makes for a great fixing for the entanglement/ premature collapse issue but kinda messed up the fire integrity of the plasterboard ceiling. Any thoughts gratefully received also.
