Can you not remove the live from the other end?
I can’t find the other ends of the cables.
Oops, maybe I’ll get my eyes recheckednext suggestion?
The live must go straight to the cu and I had a look at where the old hot water tank was but no ends there and nothing at the old room stat or pump, so when they changed the system to a combi they must have just cut the other ends. So I am left with these with the live on the connector blockCan you not remove the live from the other end? This is what I would do if possible, then just snip back as fast as you can and polyfill/plaster over.
Originally tested with a volt pen so it showed one set live and 5he others dead 5hen tested with a multimeter across live & neutrals and nothing. Then repeated with the live set and 242v so kept testing while switching mcb ( sorry don’t know what they are called) and then found the one that killed it retested again and the powered pair was dead and repeated just to be surenext suggestion?
EDIT. If you cannot disconnect from the origin, sink a single box in the wall, terminate the ends safely, and pop on a blank panel. After all, it will be behind/above the fridge, so you won’t see it.
Note also: you have identified a live. Not sure how you discovered that? Remember that one or more of the other conductors may be a neutral. So isolation is important.
