Well..the thread is a year old, so maybe he's been taken to court for non payment, or something..

Yes indeed but this only started because the dumb meter was changed to smartWe are not really talking about a Smart meter, we are talking about a company doing something daft.
That's tricky as the property owner is receiving letters addressed to 'the occupier'.And when people do daft things or ask daft questions, they must expect daft actions or answers, and for the other party to treat what they are doing with the contempt it warrants. Like writing on a letter to the occupier not know at this address, return to sender.

Thought you said not one there any more, so what is he opening letters addressed to someone else for? They do not say the Owner, so not for him.That's tricky as the property owner is receiving letters addressed to 'the occupier'.
Meter will have a red light - if it's on solid all the time then no load is detected and the readings should never change.It makes me wonder what the meter is measuring and whether that is a standard thing?
Going back a bit further than my summary; the outbuilding SWA (which I imagine is 16mm²) was powered by a 32A switched fuse and a private meter from my friends supply. When the tenant moved out around 2005-2010 and a new one moved in he wanted his own supply so an additional meter and fused switch was fitted on the spare phase and the SWA was changed over to it.Well..the thread is a year old, so maybe he's been taken to court for non payment, or something..
As much as I would like to agree there are legal obligations regarding a letter addressed to: 'The occupier, 1 High Street' on the person legally occupying '1 High Street'.Thought you said not one there any more, so what is he opening letters addressed to someone else for? They do not say the Owner, so not for him.
Yes, I know it is daft, but two can play at that game.
If that is the case then the provider can pay for it themselves! I've never been aware of any other form of meter being an energy liability to the customer — such as E7 RTS/contactor etc except I have known it to be wired on the metered side when remote from the cutout.90Wh/week is a load of not much more than 500mW.
Maybe it's the meter itself.

The 3ph supply is a legacy from the days of it being a real farm with a herd of cows but that aspect is long gone.As you rightly say, he has to open the letter, but there is a further problem, the three-phase supply must have been asked for by someone. Even if the meter is not registered to anyone at that address.
But also someone must have agreed to have smart meters fitted, and if the supply has nothing to do with the owner, then the person who agreed to have the smart meter fitted, would need to sort it out, I have been rather surprised with meters, and how if the tenant pays the bill, he can get the meter changed, any other installation in the building, the landlord can stipulate what is done, I know my son worked on council houses, re-wiring them, and not only were chandeliers fitted by tenants removed, the tenant was charged to have them removed. It was on the agreement that fittings could not be touched.
There are some odd laws, I know I have to allow Ofcom assess to my house, but only because I hold an amateur radio licence, otherwise they could not assess my house.
But with electric, there are an array of firms who can bill you or pay you for electric used or supplied, so before any could ask for money, there has to be an agreement in place. And that's the bit that does not make sense. My smart meter was fitted be British Gas, who was given the account when some other supplier went to the wall, but I now pay Octopus, and for that to happen I had to sign an agreement.
Possibly, I'm not in intimate contact with him and our last contact may very well have been this thread of a year ago.So something seems missing in the telling of the tail.

why the 3rd meter was changed I have no idea.
Totally agree, so why are they trying to get payment now by attempting to create a customer for it now?Cheaper to do it at the same time as the others than on a separate visit, therefore more profit on the new service connection fee if ever anybody wanted one in the future?
Yes I didYou told us they'd been billing "the occupier" since the day the meter was installed.

But also someone must have agreed to have smart meters fitted, and if the supply has nothing to do with the owner, then the person who agreed to have the smart meter fitted, would need to sort it out
