Where the armour has been cut back, is it exposed - either directly or after opening an enclosure? Because a nail could make the armour live with no ADS, then a child (first case) or sparky (second case) could touch the live armour. I'd definitely give that a C2.

Yes the armour is exposed, it has just been cut back roughly about a foot out of the ground.  I left it as a C2 anyway.  It was a pretty rough job.

Yuk! Thank you for the picture, which I had not seen earlier.

In fairness to the householder (or any other lay person), it is not obvious how to install SWA. At least in this case, the armour might protect against a spade if not a fork.

Given the L-E reversal, I conclude that there is at least a CPC in the cable.
