Socket Wiring Advice

[nero44]

Not sure I follow. I would need the white JB to manage the lightswitch, so that would need to stay.

The black JB has one incoming and the other one is serving a double socket. I would continue to have a socket there in the lower part of the shelf. Are suggesting just to twin the two 2.5mm together going into the FCU (so the socket can still get the un-downrated current) and on the other side 1.5mm up to the white one feeding the lights?

Thanks both, that has given me enough options to do this correctly.

(Maybe) last question on this... regarding the socket that is running off this, I plan to just run a fresh wire from the FCU down to the lower shelf where I plan to install the socket (Blue). There is obviously an existing cable going down into the floor come comes up inside the skirting board (Red). What would be good practice to handle this unused cable. I cannot remove it, but it will be completely disconnected from anything.

As you can see on the second photo, there is limited space (only terminal blocks I reckon, as I still need to put a piece of plywood to close the skirting). But if this is fully disconnected from anything, can I just cover the ends with insulation tape and a little note or so to indicate it is not connected to anything?

Opted for the twist/insulate/label method… done the same on the other side and it just pushed inside the wall out of the way

In the circumstances I think I'd joine the wires in the 'abandoned cable' together and label in some way that won't fade, such as sharpie pen on the grey sheath or a paper tag.

What are the chances of diverting the existing loft cable to the socket in adjacent room?
What are the chances of running a cable from the new FCU to the exixting loft sockets?
This looks like a good solution with minimal JB's and no spurs:

Very acceptable in the circumstances.
