Help on how to : Shed wiring.

why not? cant i use trunking/conduit

You can use conduit, provided it is made from galvanised steel and installed properly.
It will cost far more than armoured cable and take a lot longer to install as well.

Right electrician came round and told me that the socket I was intending to use used to be the boiler socket which supposingly sat above the sink.

So he just isolated the socket by tripping the fuse at the C/Unit.

As its rented accomodation and we can do whatever to the house (checked with the landlord).... is there any easy fix for this.

As when you take the socket off the wall theres the L N and E cable there.??

So that socket is the only one on that circuit?

Is it a radial? What cable size and device rating?

I would be gobsmacked if "do whatever to the house" included dangerous electrical work.

Or work which was illegal, but I don't know what the law in Scotland says.

You need to check that they are actually connected by doing continuity tests.

You then need to measure the earth fault loop impedance at the socket, add on the expected R1+R2 for the cable to the shed and the cables there to check that it will be safe before you start.

You then need to find a way to join the cable at that switch to armoured cable which you run in a trench to the shed and join it there to the cables in the shed. The easiest way would probably be to put a waterproof enclosure on the outside of the house, CW gland on the bottom, SWA cores through the wall and crimped onto the internal cable. Same idea at the shed end.

You'll need to use a banjo or earth nut on the glands to ensure the armour is earthed.

See the Wiki article on working with SWA.

Then when it's done you need to do continuity, insulation resistance, polarity and fault-loop tests at the shed.

So yes - reasonably easy if you're competent.

I recently had the same questions, sort of, I believe you'll find all you need to know here:

Your options are to run it from the CU or preferably run it as a sub main, you can't run it off a kitchen socket and you can't run it without armoured cable. Also, you can't run it, as in you personally. There's quite a lot to it and you need an electrician.
