The only live has the connector block the others are dead the floor above is floored how would you do this ?
Thanks
 
Probably in need of more information here.

What ends? What are they from? what is planned for them?
Why are they not disconnected at source?
the floor above what? where are they?

Perhaps put all in separate connector blocks/wago's and then enclose within a wagobox.
 
They were from an old time clock for an old back boiler and pump heating system from many years back, above is the attic which has been floored with chipboard sheets and I can’t find the other ends of the cables. I tested them and they are all dead bar the one cable which only goes off when a certain breaker is off. I only found them a few months back buried in the wall so pulled them up to ceiling level so I could get a inbuilt fridge fitted.
 
Oops sorry thought these were up

Can 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.

I can’t find the other ends of the cables.

next 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.

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 block

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 sure
 
If they’re from an old back boiler as you say, they may go to behind sockets, had this recently.
 
Okay so if fitting in a back box with blank face plate do I strip the ends even If dead
