I quite often run 2 core swa, it's easier to work with and CPC is bigger than the earth cable would be. Just got to be terminated correctly. The first time I stumbled across an installation like this it confused me totally cos they don't teach this anymore.
i do the same, almost always use the armour as the CPC. if there is a spare core ill use that too
piranha nuts also make it much easier
Swapping a load of outside lights to LED currently wired in 2 core SWA. Nothing wrong with any of it, all properly installed and terminated (by me) 20 years ago and has been working correctly ever since.
Used to see conduit used as CPC a lot in schools, nothing wrong with it until some numpty comes along and loosely threads on 10 couplers and nipples to make the tube reach the new board.

I always use armour as cpc from choice, but we are it seems overrun with 5WW round here because none of the wholesalers stock it anymore.
It's 3 core or special order for 2 core with carriage and minimum orders!
I even had one sales guy in a wholesaler tell me 2 core was illegal!
I just laughed.
Saved quite a bit on even 2.5 2c when we bought 20km of the stuff over 3c.
The issue with adding an external cpc is that it has to be fully rated, you can't just "top up" if the swa is too small.
I do like Piranha nuts too.

5 week wonders don't exist in Ireland on either side of the border. Unless you do an apprenticeship you are forever a labourer and that's it.
Perhaps that's why we use flanged couplers. I know of a few boys who went to london to work and they came back laughing at how rough the work was and they could get away with it. They were working beside wembley stadium. They thought it was a free for all taking shortcuts left right and centre, they were just following the example of their english co-workers.

A CPC in conduit! “Tunny” my then foreman would be beating me about the head with the piece of 4x3 timber I used as a bending block if I even thought of committing such a heinous crime.

I've never seen a bending block or know how to use one being a youngster :Blushing Do you know of any videos as would be interested to see it work?

As I say, the use of flanged couplers remains universal practice in this part of the world.

It has to be said that one good thing about the training here is, as you say, that a full Apprenticeship is required to enter the industry. (Or I suppose an Adult Traineeship although I don't think that's very usual.)
Without this proper training a prospective contractor could not join RECI for example.

There are, of course, but they have been through proper training and become rough all on their own.
My compatriot is correct though in stating that there is no (nor has there ever been any) fasttrack into the industry here.
Too be honest I don’t think you will find much, it was one of those things you were taught as an apprentice. You’d be given a lump of wood and told to bugger off and make your own. 3”x4” about 3’6” long, great for putting sets in. drill two sets of clearance holes for 20 and 25mm conduit.
Mine travelled all over the works with me. It wasn’t just used for conduit, at one point it was jambed in holding a substation roof up. Last used to get a compressor on line, I used it to hit the unloader valve.
