I admit to not taking too much notice of the 18th edition changes as I only took my 18th exam last week (no excuses I am not a good spark like most on here).

I have a flat to do that needs the lighting circuit rewired, but being the ceilings are like concrete and the owners don't want major disruption, it will be done in mini trunking. I usually use self adhesive trunking and seal it with white no nails to give it a strong fixing as drilling through concrete to fix screws in will be an absolute nightmare. So where do I technically stand not using metal fixings to secure it?

Why is that? SDS drills are mighty powerful, then an impact driver to drive a concrete screw into the hole. Did a load of steel conduit last month into concrete walls and ceilings that way.
 
Unfortunetly you can no longer simply use sticky back trunking for re-wires. The plastic trunking and more importantly the cables in the trunking have to be fixed to the fabric of the building using a metal fixing.
There are many ways to achieve this from purpose made clips to a bit of cut up metal bandy strap.
Either way every single method will require fixing to the ceiling in this case.
Nomore nails glue will not meet the new regs
 
How old is the flat and how is the current wiring run around the flat, did a job with my uncle many years back in a 1920's block and managed to utilise the old conduit and run in singe core cables.

Not sure how old the flat is, but I would guess 1940s. The current lighting circuit is in singles and is run inside steel conduit. I always try pulling singles through, but I haven't had much luck with similar set ups in the past.
 
a bit of chip fat mixed with fairy liquid does wonders. cables will end up clean and greasy at the same time.
 
Forgive my naivety, but if I run mini trunking along the ceilings, are the metal fixings to support it supposed to completely cover the mini trunking. The reason I ask is because if the fixings are inside the trunking and a fire started, then the trunking covers would just collapse and the cables fall out?

I appreciate this new requirement is as a result of a very unfortunate incident causing the deaths of firemen, but in reality aren't there many other unsafe practices occurring everyday that are ignored (unless a part pee log is used).

Running 16mm mini trunking in a corner of a room is highly unlikely to trap someone in a building.

Also, if the mini trunking is fitted above the skirting boards, does that also have to adhere to the same criteria in case a person under 6" tall gets trapped under it?
 
sticky back the trunking on, then use metal clips on the cable inside the trunking. several varieties to choose from, even more than heinz57.

at least with concrete ceilings he can fit 50kg chandeliers without reinforcement.
