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 isolatethe cable in a
junction box in the ceiling void and then join the new cable
in this box?

If it is going to be inaccessible (as this will be) then the joints
need to be crimp types and not screw terminals (as in chocolate block)

He could just lie a junction box under the floorboards of the
floor above and make sure that there's a screw-down panel which
can be removed for access.
