Hi All,
I have a couple of questions regarding running SWA cable between the Internal House CU and The Shed New CU.

The shed is basically being used as a home office and as such has a 6A lighting circuit and 16A Circuit for Socket outlets. Will be running a couple of computers and Monitors.

So, First things first, I understand that running power out to the Shed is notifiable, however I'm not Part P registered, however I do design electrical systems for ships, so I'm a bit beyond a normal DIYer.

House is pretty old and not had a re-wire for a long time.
TN-S Earthing.
I think a new CU in the house is probably best.
RCD protected for House Circuits, Seperate 32A MCBO for supply to Shed, as the Shed CU has its own RCD.
Can the House CU be Changed and retain the original RED/Black house wires?

I need some advice on running the SWA cable from the house CU to the Shed.
Plan is the use 6mm2 SWA, correct glands for earthing or the armour to the Metal CUs and one core for Earth as well as the Armour.

The house has Suspended wooden floor so running the SWA from the consumer unit to the exterior wall is no problem.
Is there a specific requirement for the height the cable must enter/exit the building?
Should the SWA be chased into the wall internally before it goes through the cavity if it has to come out at a certain height?

Once on the outside it will be clipped along the exterior wall where it will head to shed...
Entry through side panelling with drip loop and then into Shed CU.

Shed distribution from Shed Cu is all done in conduit and already wired ready to go.....

Thanks in advance for any input and help, have a beer on me!
