Supplying outbuilding, bonding and earthing

[westward10]

OMG look at the main earthing conductor wrapped in the green n yellow tape looks like its actually some of the steel wire armorings no gland there then!

It is indeed.

I think I'm losing the plot on this thread.... is the OP planning to run a cable back to the CU shown in the first post?

No the cable is running to the CU in the post from the CU at the origin.

But didn't he say that the outbuilding was spurred off the kitchen ring - or is this CU the one in the outbuilding?

Yeah sorry the CU in the post is coming from a socket via the SWA in question.

So if is was me..... I would quote to rewire the kitchen, quote to inspect the outbuilding, quote to run a new submain to from the main CU to the outbuilding and if the EICR on the outbuilding shows up anything, that would be included too.
I'm guessing that this "outbuilding" will be let to some unsuspecting tenant so I'd be VERY careful about what signed off.

and if the client didn't like my quote, then I wouldn't be shedding any tears.

If they can afford a new kitchen, they can afford to sort out the fiasco of a submain and the outbuilding too.

Anyone who contemplates much less shouldn't be selling their services as a competent spark IMHO.

If the standard of work is like the CU it is likely to be a mess.

Ok Guys,
Went there today to talk about options and they want to redo this outbuilding so it's only for storage. They going to remove boiler and water and gas services will be terminated. So now it's only the case of new small consumer unit for lighting and few sockets.
Testing will confirm whether to reuse some of existing wiring or rewire all.

I did some resistance test between met and metal services in outbuilding and the resistance was below 2000 ohms so definitely needed bonding.
Adiabatics also gave me csa of earth 5.31mm. With that in mind would I still have to run another 10mm bonding or 3rd core would work fine parallel with armour as combine earth/bonding?

I seem to remember that you cannot combine swa & core, as form of earthing or bonding, but I might be wrong. What was the exact reading you obtained for suspect extraneous conductive parts?
