Using cpc as neutral

The 5 core cables were coming from the controls downstairs, as already explained. As was the cpc contained within supply cable. I'll have to remember to ask the wholesaler for a 5 core which doesn't contain a green/yellow covered conductor next time.

You can get YY flex or 7 core flex.

I'm not sure the wholesaler has 7 core flex, needed some to wire up a Rayburn once and it was a nightmare to find. That was a few years ago mind. Not heard of YY flex, does it not have a green/yellow core? Anyway, I'm sure there's nothing wrong with using the cpc in a multicore flex as long as it's identified properly, and it's not specifically prohibited in 7671 like an un-insulated cpc is. I go to great lengths to ensure that identification stays put

It will be hard to find YY cable that doesn't have the below comment in their specs. All depends on what you are using the YY cable for.

I Work on the basis that it's best to have a CPC in every cable I run ..

It certainly makes testing easier.

Tell you the truth mate, after 77 posts I lost the will to live, as well as what he was using the cable for...

Came across this with the LIVES on an EICR last week - 1 x 3 wago later it was sorted

I've had that before - in the absence of a live loop they'd twisted the lives together and stuck a bit of sellotape over the copper. Every light fitting in the house was the same.
I'd only gone to put up a smoke detector.
