Situation is there's some 53 year old pyro cable that I need to either remove, or make dead, or cut short and push back into the wall having ensured that the still-live end cannot short out the circuit or come into contact with anything.

No hope of fully removing it, as it goes up the cavity and I don't even know the route it takes.
Chances of finding the junction box that connects it to the downstairs power ring are remote, I suspect it connects at a junction box fixed into the wall behind fixed cupboards, next to pipes, in a kitchen, and below the bath (bathroom above the kitchen), however I cannot be sure. I also am not sure I can take the cupboards down without damaging them (I'm no carpenter/kitchen fitter).

SKIP TO THE POINT:

The obvious thing to do seems to be to cut the cable just after it leaves the outside house, fix the end in such a way that it's not going to short the circuit or make live anything it comes into contact with, and shove it back into the wall (then cement over it). I've not had to deal with pyro before, how would you recommend going about this?

I can just imagine at one of the Electricians training centres, "what about Pyro the Mate" ""oh don't concern yourself with that, you wont find any of that stuff in a domestic situation"" "you will never need to know how to work with it, just concentrate on the cubicle for your practical test"
 
OK I will give you that, but I would be interested how many electricians can terminate an end correctly with confidence.
I haven't touched MICC since I retired some5 years ago, I had a call from a mate who had never touched it, would I give him a hand, made 2 ends off on a 4l2.5 no troubles. It's like a lot of things really, take your time, follow the correct procedure, as I said, simples. The biggest problem I had was setting the stripper properly. I remember when it first came into service in a big way.
 
Hey OP have you disappeared, have you actually opened up some accessories to find this cable to disconnect it or are you taking the hide in the wall as the best Approach?
 
Whenever you come across copper pyro always inform the client that the whole lot has to be pulled out and replaced. No fafing about remove the whole lot end of.
Your post lack emoticons so cannot tell if your joking or not, if not are you suggesting that you remove some off the toughest most durable cable and change it for something a lot lesser just because one might not be skilled in using MICC and consider it a faff to deal with?
I would have thought what is best for the customer comes before what is best for you.
 
Pyro a dark art ?. You're electricians even if you never do it, is it still not part of the apprenticeship you can read the instructions on the bloody packet. Just because you can't stick it in connectors and wrap it in tape people won't work with it. I've seen it still serviceable in domestic and sparks rip it out because they'd rather use t+e. Same with conduit because they can't wire in singles. I used to hate being referred to as a house basher, but the term seems more apt than ever. Domestic is flooded with Cowboys . Also when looking for a blade for my joi stripper Google threw up some interesting search returns.
