It's not exactly a Herculean task to dig the filler out....
Mmmm how to run an outside cable from this consumer unit?

At least bringing the cores and the sheath (that is between the cores and steel armour) in through the wall means the connections ( if any ) are inside the house and thus not prone to weather effects such as condensation of vapour from inside the house / cavity creating water in the external junction box
True if the ducting is not necessary.
In an area where digging may occur in the future then ducting is a benefit that is almost 100% necessary. It it gives an extra inch or so of warning for the digger to be stopped before the sheath of the SWA is damaged. ( assuming there is a person watching the inch by inch excavation under the warning tape ).
And if the SWA is damaged then pulling a new length through the repaired duct is probably much better than having to make an underground joint from the digger mutilated ends of the SWA.
Or just wrap gaffer tape round the exposed steel and hope it doesn't corrode too quickly and interrupt the earth continuity.

What BS cable standard applies to the part of a SWA cable you are left with when you've removed the outer sheath and the armour?
Mmmm tonnes of ideas flowing....
FP 200 cable from consumer unit (RCD protected).... Then through wall and terminate in external box. In external box, SWA cable. From there follow the wall of the house before turning down to the ground and into a duct (ducting needed as paving going down before power run to shed). SWA through ducting then terminated in shed. 2 way CU in shed to supply lights and a double socket.

Am I missing something here? Why not just drill thru the wall at a steep down hill angle (viewed form inside)? No bending radii are going to be exceeded then.
Ok drew a small plan here. In a nutshell this is what I envisage.
If you draw that looking from above, you still have a sharp bend in the SWA where it exits the hole in the wall and turns to run horizontally. Better to continue downwards from the exit hole and then you can put in a wider radius turn to run along the wall.
Sure that'd make more sense.
As suggested, ducting swept up inside a plastic pipe into an enclosure on the wall.
Will look much better than SWA cleated to the wall like that.

I see your point. Esp if a cleat fell off then the cable would just 'hang' off the wall. Plastic conduit for the SWA to run through will look better aesthetically I suppose. Thanks for the ideas and inputs so far. Just trying to think this through properly.
I see what you mean now. Just trying to avoid digging up the slabs and avoiding the waste pipe that runs parallel. I'd hate to drill through that!
Thought you were putting in the ducting before the slabs were put down?
