Earthed galv'd be better..

not really, afaict there are no safe zones in a floor and anything able to go through concrete is liable to go through PVC pretty damn quickly.

earthed galv conduit is the way to go here IMO. Try to keep the number of bends to a minimum and use pulled bends not elbows.

Don't borrow a pipe bender designed for copper from your plumber mate

A Building inspector will not let you run the cables under the screed,unless its accessable via a suitable trunking i.e metal set in to the screed. If you go down the trunking route then it still has to be accessable trough any floor covering. Whats wrong with running cables through new roof timbers. you must have wires in a first floor void?

Hmm, buried deep and in earthed mechanical protection is fine.

Some building inspectors do get a bit 4nal about such things though! Stick to roof trusses, insulation and damp courses I say!

Doing loads of work in places with pcv/pvc buried into the screed atm, sure glad that stuff isn't so common nowadays!

On what legal basis?

Who says so?
