Try it from the other side of the fence. A Council rewire and I am subcontracted to do the rewire.
The snag list appears and the only snag is "kitcken sink not bonded". I explained that it is a plastic kitchen sink but it fell on deaf ears.
Your supplier should be able to tell you what sort of supply you have (TT, TN-S or TN-C-S)
If it is a TN supply then then the supplier has provided you with an earth point that you can use.
You would certainly want a suppliers earth if the cutout is in a metal box.
Probably not the best solution, but I suspect that the metal case will do the job.
No earth is risky, no earth and no RCD is dangerous.

You (or an electrician) would need to test that the green wire or conduit is actually connected to earth. Somewhere, at the bottom of the close, it should be connected to the supplier's cable armour, or the supply neutral, or an earth rod(s). Testing it needs a proper earth tester, not a multimeter.
I'm also not terribly impressed by the way the live fuses have been commoned together. And I'd like to see the whole mains meggered before someone gets a fatal shock off any old metal-clad close light switches.
You weren't the person having lightning sparks from the boiler were you?

But not necessarily as a separate incoming conductor. The consumer PE can be connected to the incoming neutral at the consumer end.
Thats TN-C-S for you:-)
It will not have it any other way.

Ah, I missed that. Was wondering where the neighbour's live feed came from.
No one has commented on the two incoming lives (two phases?) sharing one neutral wire.
Kinda impressed by the way the supplier's earth has been connected to the box metal without cutting the wire as it passes from top to bottom.
bonded". I
I was thinking along the lines of "box tickers, don't you just love 'em" along with correcting the "problem" and associated invoice. When the invoice is paid a call to the local newspaper and either return of the payment (if they can accept it!) or donation to a local charity.
It's the ESQCR, Regulation 24 (4):
"Unless he can reasonably conclude that it is inappropriate for reasons of safety, a distributor shall, when providing a new connection at low voltage, make available his supply neutral conductor or, if appropriate, the protective conductor of his network for connection to the protective conductor of the consumer?s installation."
AFAIK DNOs are not under any obligation to provide TN earthing to existing older supplies, although they will sometimes do so if you ask.
And if my experience is to go from, charge through the nose.
Yes, I brought this up a month or so ago when an Inspector told me my earth clamp was the wrong type, and should be changed. He also said I could not do it myself, as the wires up to the meter were the property and responsibility of the supplier. Neither my electric supplier, or the distributor would come out to replace the clamp. They would however fit a new TN-C-S supply, at a cost of £360.
They said I should get an electrician in to change the clamp. The ELECSA Inspector said no-one apart from the supplier was to touch it. I will be diying it, as I got the proper clamp last week. Alan.
We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember google saying something like:
I'm afraid the usual option of banging in an earth spike is not open to you, unless you have very understanding neighbours below.
