I'm installing a kitchen in a couple of weeks time and have a question.

I have to move my heater/water controller from one wall to another it has
8
wires. As I'm going to need more wire to move the box is it okay to
isolate
the cable in a junction box in the ceiling void and then join the new
cable
in this box?

I'd thought it to be no problem but thought I'd ask first.

best to replace the cable complete, as it wil be difficult to access later
when everything is put back.
you will know the joint is there in the ceiling void, but the next person
who buys your house wont. bear in mind that you could end up in a house
where someone else had done this, imagine how ****ed off you'd be if there
was a loose connection and you couldn't find it.
