into conduit along wall>wall mounted switched spur box>out back of this into back of mains Double socket.
It's the end bit that I'm struggling to visualise. Maybe a pic or drawing?
As for running the lead in the virgin media conduit - surely if we know its there - damage is very unlikely - i appreciate its against regs.
I mean this is it isn't it?
I guess with any diy electrical work there's an insurance risk, but ultimately if it's safe I don't really think you need to get hung up on regs. You could always use armoured cable just in case.
We've got an external armoured cable running under our patio. Ultimately it'll have an out door socket on one end and the other end next to the shed will connect into some sort of plug to be plugged into a socket. No idea of the regs associated with that, but it'll only be plugged in occasionally running led Xmas lights and maybe some led evening nights (possibly combined with a phone charger or baby monitor) when we're out there - so where's the risk?
After seeing that laying an armoured cable just consists of laying an armored cable I'm a bit annoyed I didn't diy when we were having our drive done. The total electrician cost meant it was vetoed, but in hindsight I could have just layed a cable myself and at least it would be there. Plus I could have sorted out a trickle charging setup for ky motorcycle. #grumble

Main risk with electrics outside the house is electrocution due to differences in earth impedance preventing the breaker operating. Largely that's what you're paying an electrician to do, properly specify and test the installation.
It seems like you're on the right track with your installation but there would be a lot of dangerous attempts if the regs allowed anyone to have a crack at it and a lot of reasons for that are cost saving.
Tricky thing is the socket is on the party wall - not the rear wall which is actually window frame - it's a 60's crosswall.
How does this sound... 4 gang extension lead in shed > out of shed (via hole) > into outside socket (with rcd) > though windowframe>into conduit along wall>wall mounted switched spur box>out back of this into back of mains Double socket.
Then I can switch the power off from inside the house on a daily basis or completely disconnect at the outside socket for longer periods ?

oh and thanks to you and all esp. @stevo_com - for the advice ;-)
