Running SWA on outside of building to feed part of internal ring

[sidekick]

Have come accross a job where house ring run in T/E but has an old extension with earthed metal conduit used for sockets and only live and neutral single cores (of which are both black here).
The earth continuity is greater than 500 ohms and the live is faulty between 2 sockets and disconnected.
For now I have down rated mcb to 16A and looking at rewiring the sockets with the conduit wiring.
My issue is that it is a solid floor covered with laminate, a flat roof and internal walls are stone with current metal conduit and boxes fitted during build within the stone work.
Would it be acceptable to rewire the sockets using SWA on the outside of the building to replace this part of the ring (5 sockets in total to rewire on a final circuit of 18)
Any other ideas/advice appreciated as cannot seem to find any other way.

I can’t see a problem with what you intend to do if you are in the uk.
local regulations may prohibit it though and you don’t mention where in the world this is.

If clipped to the external wall NYY-J would be easier to work with.

Can you pull the existing wires through the conduit and pull in new ones along with a CPC to link all ends of the conduit/accessories?

If not then the suggestion of NYY-J outside makes sense.

Agree, why not pull new main cores and CPC using the old.

If its a concreted in run, the installer usually plans the run suitable for a new pull through (though not allways)
