Just putting in a fused spur off the ring main - only 6 inches away from
existing double socket


Thanks for all responses - much appreciated.
I phoned the electrician who had done the installation of the new kitchen -
and told him of the problem. He was round the house like a rat up a drain -
obviously very concerned when I described the diagonally running cable.

BUT: as soon as he saw it - he said red and black - and heaved a sigh of
relief.
I had not spotted the colours - it was an existing cooker cable which was
already in place from years ago.
However, he said if one of his men had done it - he would have sacked them -
and he would have put in a new compliant cable.
So - I just need to fix in a new 6" length.
I am assuming crimping rather than a push-fit Wago type is preferred - views?

Depends on where the join is going to end up... if its a joint in a box
of some sort, then either will be fine.

Wagos on a cooker cable... They'll get hotter than the cooker...

The way I was reading it, the cooker cable was the one in the way due to
its routing in an unexpected place, not the one actually being extended?

If you need something
approaching the slimness of a cable so that you can bury the joint in
plaster, then crimps and heat shrink would be a better choice.

I would not try and make an inaccessible join in a cooker (or shower)
cable. I used a giant chocolate block connecter designed for cable of
twice the crossectional area, and ran both the conductors to be joined
under both terminal screws to make a good connection. This can be housed
in a flush box with a blanking plate.

If the damage is near one cable end, I would replace that short piece
to the end rather than make two joins.

High current joins need to be made to a high standard of workmanship,
or they may overheat.

Yup agreed...

To be fair I have not tried the large wagos on "big" cables. (the large
6mm^2 capable wagos are rated at 41A supposedly)
