411.3.1.1 A circuit protective conductor shall be run and terminated at each point in wiring and at each accessory except a lampholder having no exposed-condutive parts and suspended from such a point
Cheaper than the 4 core!
^^^^ Father Jack just bought the 4-core by the look of it....
Arse? Really?
Sadly, it says " For interior use only. "

With respect to the former flex, that is due to the sheath not being UV resistant.
Can you slip some conduit over it?

That was to illustrate a possible cable type.
One ebay search later:

Assuming your email addy works, YHM.
Any use mate?
And that is IMHO a good offer.
It's just a way of making the link a bit shorter, not a personal comment. Screwfix and many others (amazon esp) insist on padding links on their sites with unnecessary junk, you must have something in that field so I shorten it with just a few (often random) letters.
This works just as well:
but I prefer to avoid the wrap.
Anything they add after the 5 digit partcode is just padding too, usually it's for tracking which I object to.
That's just the usual, "plasticised PVC sheathed cable is unsuitable for use outdoors" nonsense, yes, it will become more brittle after sustained (many years) exposure to UV but provided it is used in a fixed installation it will be no worse than using a non flexible PVC sheathed cable and will be perfectly safe.
Heh, I would have got away with it if it wasn't for those pesky regs :o)

Interesting - Ta.
Its not good practice IMHO, but its not actually forbidden if over marked at both ends. (it would be forbidden if it were not part of a cable form though, so green/yellow singles can't be over marked).
The subtle implication of which is that non single core cables *may* be over marked at their terminations.
The difficulty there is that the stat position must provide provision of an earth, so reusing the one that's there means you fail to meant the requirements in a different way.
Except as Adam pointed out (411.3.1.1) except if you're short of conductors and mark the CPE as something else, you no longer have a CPE, so you fail a different way ...
Presumably the risk is that someone cuts the cable mid-way to insert something or other and just assumes the cores are being used in the way you'd expect.
which is the essence of standards.
That things are done a standard way so that anyone coming along doesn't need a Haynes manual to work out which wire does what. Or whatever.
