How do I add another plug socket?

[Andeh1]

I have a socket at normal height, but it's below my desk and a real faff to plug and unplug things into. I've spent the last couple years with an extension lead sat on my desk but it looks untidy.

I would like to therefore install a double socket in the wall, above my desk, directly in line with the socket below.

It's a new build houses so the cable runs vertically upwards, behind metal sheathing. We built the house over a number of years, so I know how it's all laid out.

Id like to cut out the plasterboard snip out the metal sheath to access the cable, but the cable is obviously going to be reasonably taught, and with the metal sheath pinning it to the wall blocked from letting me rerun a cable from new socket back down to original socket.

Is there any useful tips or approaches, for splicing into the cable to allow me to install an additional socket?

Thanks

Any reason you want to keep the socket below?
Usual procedure as you say is to expose the cables back to the new location and chop a new box in.
You mention plasterboard, is it a solid or hollow wall?

I electrified my desk instead.
I have a bank of sockets on a board at the rear of my desk. they are powered from a single lead to a plug. It's all low power devices, so there's a 5amp fuse in the plug.
Half of the sockets are always live (charger adaptors, network switch). The other half are through a single switch so I can switch off without crawling on the floor. (computer, printer, amp etc) It's all fixed to the back side of the desk, I can reach the switch, but none of it is visible.

The one below is useful for a printer and a few bits that stay plugged in all the time.

It's a plasterboard wall, so I may get lucky with where the dabs are to rerun a new cable, is just like to think through my different options before I commit!

Why not just get a desktop extension?

Like this, for example, but they come in all shapes and sizes:

There are probably some easier desk mounted solutions around these days to be honest to save you the hassle of the work but dot and dab is fairly easy to work on really.

For some reason we didn't have any sockets on the wall where the head of our bed sits, do no way yo plugging phones on bedside lights.

But on other side of the wall was a double socket.

Next door is an electrician so I got him to fit a spur.

Could have done it myself but CBA.

Good job because he had to offset it as the wall is too thin to put sockets back to back.

Basically the cable for the spur crosses through the wall at an angle.

You will often find spare cable at the top of the wall. Pull gently at the cable and if there is slack it will pull down. Or just get the desk solution. It’s what I’ve done in my very new build.

Two sockets would not be enough for my desk.

I would just plug in a 4-way and mount it on the side of the desk or similar.

OTOH, spurring in a socket is not difficult, plasterboard is easy to repair assuming you don't mind repainting the wall.
That way you can have a double socket with USB outlets.
