Has anybody come across this practice before? I live in a purpose built flat with concrete floors and ceiling. The cables for the ring main and the lighting circuit are imbedded into the concrete floors and ceilings with no conduit used apart from besa back boxes which the ceiling roses are screwed to. Was this normal practice? I take it there is no way of rewiring lighting circuit unless using surface trunking? The ceiling slab is reinforced concrete with the thinnest layer of skimming imaginable. The flat was built in the early 1960’s with black outer sheath (quite tough but not rubber) and stranded cable – but it is much bigger than 2.5mm T+E. It looks like 4mm T&E Even the cooker has the same size cable!

Never seen this done before. The time that concrete was used for building accomodation then conduit was the standard way of doing things. Maybe it is some form of small flat conduit, seen it used in old properties, it is basically like a twin and earth profile, but a bit bigger and has 3 compartments with individual insulated conductors run into the three parts. A photo would probably help.
