How many properties can you run off a domestic electricity meter?

[SilliamWhale]

I have two electricity meters on the farmyard. If I wanted to convert another building to a dwelling would I have to install another separate meter? The service cable from to one meter runs but 6m away from this building I'm proposing to connect to and the powerlines to the whole farm are not much further away.

My domestic spark has suggested a totally new service cable and meter is necessary, just checking here if people run multiple buildings off one meter.

No problem with multiple supplies off one meter but what's the total max potential load of 2 houses and one farm from single 100A (?) supply.

I've been quoted £18k to 'upgrade' the transformer so I can have a good enough supply to 4 dwellings and farm workshop.
I think I'll be buying a backup generator (to run 3ph welder on) and accept the odd dimming of the lights.

Depends if you want to pay for their electric or not...... seen a building run off 2 meters as there was no 3 phase available....

I'm not sure. Farm doesn't use a lot beyond a grain fans. I've got a woodwork shop (couple of 16a tools) as well as my house which runs one electric shower and the boiler. I want to add another dwelling which beyond a boiler what is there? Cooker? Another electric shower?

The 3 powerlines are tantalisingly close to the proposed new meter but I doubt that's much consideration on the charges. Maybe I'll get another sparkys opinion

Any chance you would sell the conversion in the future ? I would be inclinded to bite the bullet now & put a new supply / meter in

What size is your existing connection?

Any decent sparky should be able to work it out

but they do like their safety margins.

Which is good if it prevents the main fuse from blowing when everyone is cooking supper at 6pm on a winters night

No reason to have another Mpan meter, just need to ensure your draw does not exceed the board fuses.
You can charge a sub meter anything you like within reason

Check you wayleaves for apparatus on your land that does not supply you

we're at the end of the line.

Well thats the end of the line for that one then

And can a sparky design a system to do that? I suppose the probablity of overload is small but maybe 2 electric showers, 2 cookers/ ovens and 2 boilers going flat out...

I would get a price to do it properly if reasonable go with it but you could use gas for heating and cooking low energy light bulbs which would make the power requirement low enough not to need a new supply that worked fine for me
But do you want to sell the new house or live in it or put staff in it if you want to sell you will have to get a new line

 

[tupmaster]

can you own the meter and charge the dwelling privately for the electric?

 

[Exfarmer]

You can purchase sub meters pretty cheaply. It means you only pay one standing charge.
If you have any renewables feeding in to the Mpan meterit means you have a chance of selling the electricity at a good rate.

Built a barn conversion here and ran it off the house meter.
Did the same at another farm of ours too.

A standard domestic single-phase supply is typically between 15 kVA (60 amp cutout fuse) up to 23 kVA (100 amp cutout fuse), depending on your location and hence what your DNO typically installs.

If you’ve got an existing three phase supply, and fairly modest demands from the farm, it should be pretty easy to take one of the phases for the new domestic connection and simply sub-meter it.

However it all depends the size of the supply going to the farm...

Know of a case where someone with a 3 phase supply to the house has just been charged £20,000 to install a single phase instead, please dont ask me why

Bonkers! I don’t get that at all.

Even if you were on an expensive HH metered connection, you can ask the DNO to down-grade the supply to a sub 100 kW supply (back to standard NHH metering)

Leccy then costs exactly the same whether you are using all three phases, two or just the one!
