3 phase at home??

[Jacktegla]

So, bit of back story my dad ling time ago had 3 phase installed into his unit and has had the supply for over 15 years now he's retired and rents the unit out however I'm starting to collect a big more gear for my ever growing tool box.

So I've recently started the build an an 8m x 8m workshop aswell as our orgional garage, so we're currently only have a 32a single phase feed from the house, however it's too small for everything now and unfeasible to dig up supply going to garage as its got a lot of paving over it all now.

So I've looked into a 3 phase supply to the garage then too the workshop. As the transformer is 20ft from the garage and post is in our land, so I've had a price which isn't cheap but nor astronomical. So now I'm looking into it further and this is where the questions start.


Would anyone have any advise how you'd go about getting a price from energy suppliers for 3 phase and to domestic premises, also how will it work having a separate supply into the garage not coming though the house.

Probably easiest to have the workshop on its own 3ph metered supply independent of the house?

and pay more standing charge being separate

That's my thoughts of what will have to happen just can't manage to find an energy supplier to talk to about this as its domestic, also will it matter being on same adress as another property for electricity supply

I'd doubt you'd be able to have 2 meters for two separate feeds and still be able to pay for it.

 

[Erie Fred]

What if you upsize the feed from the house, and buy a phase convertor ?
Yes, you'll need to dig up stuff, such is life.

What is the total cost vs getting a separate feed ?

 

[ajlelectronics]

When I arranged my power feed contracts, there were no questions about single or three phase. Just go for any supplier of your choice and if they don't ask, you can't tell them. I can't see why it would make any difference even so.
The meter number will give it away should it be of interest to them, regardless.

Three phase electrical supply to a domestic installation is not unheard of.

You may just end up with two accounts, one for your house and the other for the garage/workshop.

The DNO will need to know what load you propose to use so they can check that their network has capacity.

You may have already done those checks through the quotation process.

It really isn’t that complicated but might be a case of finding the right person to speak to at your electricity supplier.

Do bear in mind that prior to connection of the new electrical supply, they will need to see your electrical certification to verify that the new installation/s are compliant.

they connect virtually anything up without certs they just leave it turned off after connection and whoever turns it on is responsible

From my own experience I’ve never seen a new service connected without certification.

We have had a 3 phase supply to our house for over 20 years. We decided to build an extension & had to have a temporary supply laid on while the build was ongoing then a permanent supply. Engineer came to look at the job & i asked if 3 phase was possible as it was up on the pole already.
No problem at all, price for a new single phase supply was £387, 3 phase supply £487, No contest!
In our case they just fitted a 3 phase meter to the house & the main cable was run from there to the workshop.
One phase was split off to power the house. Its all run off the one 3 phase meter.
Never had any problems. I suspect it would cost a lot more today!

Yet I have never ever had it requested, domestic nor commercial.

Worth having the three phase laid on and metered as a domestic supply, there are no concessions/capping of rates on industrial supplies.

all they used to do was you send or give them a simple test notice that they supplied and that was it now they dont even want that its all privatised so they dont even test all they want is a db a set of mains tails and the earth wire

Ours is down as a domestic supply, now on a smart meter. It took the supplier about a year to get it into their thick skulls that a single phase smart meter wasnt going to fit! Several visits from engineers, "Ooh its 3 phase, I cant fit one of those". We did tell them. Eventually they got it right!

Exactly what I have here. Single phase with a meter to the house. Three phase 100A per phase to my workshop. Both meters/supplies are on one account, but 2 MPAN id's which always causes confusion when I switch suppliers; so 2 lots of standing charge, which used to be small but now is around 60P per day per meter. Did have a bit of a discussion with the supplier re. the workshop 3 phase supply being domestic when I had it installed. The standing charge was a lot more (20 + years ago) for a commercial/business supply, don't know about nowadays.

 

[Jelly_Sheffield]

I spoke to my DNO about this, as I have 3Ph on the wall outside.

At the time, their engineer (they did a visit to inspect and determine if they could take off the existing lines) said that I just had to give my supplier reasonable notice that I was having my connection replaced, and it would be on them to would then come and fit a suitable meter, crucially, if they couldn't do it before or at the point of the connection changing, it (and any unmetered electricity) was a them problem.

In the end, a RPC and Genset worked out cheaper, although I kinda wish I had just done it for space and convenience.

 

[Barking Mat]

It's not cheap I've got it, I try to balance the phases but it's not cheap.

I'm in France this may not be useful.

 

[awemawson]

I’ve got three phase to my workshop, which is separate from the house but classed as domestic (so vat at 5%)
They wanted a small fortune to connect it, over head from a transformer that’s about 50 foot away on my land. But when they wanted me to grant a way leave for them to re-cable some of their poles they suddenly changed their mind and fitted me a 160 amp per phase 3 phase supply FOC !

As an aside they are replacing the transformer this coming Tuesday as people upstream want more power. It’s 100kva and they are replacing it with a 200kva one theoretically on the same pair of poles. We’ll see !

If it's on your land how much rent do they pay you every year?
I have a customer who has a transformer on his land and gets about 2.5k a year from them for easement!
