adding outside light to shed

[beacon182]

Hi all,

My block-built shed currently has a mini-consumer unit feeding one double socket and one single light switch controlling a single lighting point. This work was only done last year when I moved in by a proper sparks so is all modern etc, but now I want to add an outside light on the wall of the shed but I will have trouble getting a sparks in just for that, especially down here in Cornwall, so I want to do it myself.
From my limited knowledge, I think/know I need to insert a junction box with a spur to the new lighting point and another to the new 2-gang switch, but I'm not sure where to position it: on the existing cable from the CU to the switch? or on the existing cable from the switch to the current inside lighting point... Or should I continue the circuit from the existing lighting point (a batten fitting)? What's the simple way of doing this job and what connections do I need to make in the junction box and at the switch? I have already fitted the light outside and fed a wire in, and I've also changed the switch to a 2-gang, but connected nothing else up yet.
Any help much appreciated!

Simple for you just to stick a plug on the end and stick it in your socket.

You could spur off from the the back of the socket with a switched fuse spur.
you can then put the switched fuse spur near the shed door for ease or have it switching via a PIR or dawn to dusk.
This way you are not wasting one of your 2 sockets.

Just ensure that you correctly rate the fuse in the fuse spur and use the correct cable for the conditions.

out door location needs to be checked under part p unless is plugged in with a 13 amp plug then its temporary not fixed
although going through walls and clips can make it fixed so still need part p certification
so you need it to be very loose to save argument
