We have taken out a partition in modern uk house and there were 2 sockets either side. The cable to them is not long enough to allow the sockets to go to either side now, so is it possible to use some product and an extra piece of wire to extend them both.
Or do we trim them and finish the circuit with a junction box to stop the ends being live ?
Thanks for ideas , safety is the prime important thing.
We cannot easily trace the wire back as it disappears into the ceiling joist through a hole.
