If it's a new build, just mount an isolator for them to run the meter tails into, shouldn't need certification for that.

His was upgraded a year or so ago, due to a new housing development nearby. I don't know if he had a new agreement with them when that happened, he's a very shrewd man and wouldn't put it past him!

Some units I did earlier this year had 3phase supply installed prior to them being finished.
The supply and cut outs were installed, the metering will be done by the energy provider when they sign up.
We left our installation with an isolator for them to connect to.
And an EIC for each unit!

Tried thr cost of just upgrading single phase supply and is only £1000 cheaper. Also trust me won't be digging up my dads path he's had done, that's one of those definetes haha

Ok thanks will look into it more . Coming onto the dno checks yes I've had all this done and they will have yo install a new transformer. As I could be wrong here bit I belive these an issue with it from previous experience as the unit pulls a 3 phase supply then our house and our neighbour pull a single phase off each however our neighbour was having power dips so they moved them overto another. So I presume either a supply issue or transformer issue

Lad I know has 3ph at a home workshop,
Had it as a separate/new installation
That worked out cheaper as there was some sort of new customer/connection installation discount. Different supplier to his house one.
He already had a hefty 1ph cable running from the house to the workshop so has swapped things around so the house now backfeeds from the workshop supply. He has changed the house supplier to one with no standing charge. Not sure why he didn't cancel the house supply completely?
Also, a neighbour has just had 3ph installed alongside a large (for domestic) solar array.
Apparently he needed to have the 3ph to be able to export the solar.
Reckoned the 3ph installation cost nearas much as the solar.
If that's actually the case then I'm guessing the solar must run a 3ph inverter?
If so, and the costs are comparable, and the inverter has sufficient output, I'd look into the price of solar just for my own use.
I did have 3ph in the last workshop. Not in the current one.
I've got a transwave that let's me run most of the kit although that's all stuff that is readily available in 1ph anyway (chopsaw, bandsaw etc)
I've moved the big mill to a relatives farm but don't really use it much anyway. Big lathe is also there but thats 1ph.
I do miss the 300a mig but I don't miss the jobs that I was doing with it!!
Plasma cutter is the only thing I really miss. Again, not something I used loads but was certainly nice to have available.
I'd weigh up how much you will use it and compare to the installation/running costs.
I did and decided it wasn't worth it.
Did say I'd just buy a 3ph generator the first time I really 'needed' it but never have.
I also have 1ph generators that I regularly higher out so it's not even the cost of the 3ph gen that's stopped me getting one.

The cost of installation isn't awful in my eyes anyway, the thing I'm trying to work out is the ongoing cost of standing charge and usage, I looked into generators but they're the same price as the instalation and just bit of a pain and noise.
The main reason is I don't physically have enough single phase piwer coming to the garage to run another 2/3 sheds. So really I need to sort out having more power some how.
Lots of the tools I already have are 3 phase and qheb looking at more the cost is significantly cheaper for the 3 phase aswell as availability such as like my lathe is 3hp but the one I want is 7.5kw so by tike I've in vested in more single phase and phase converter could have a 3 phase supply.
To be honest though if I had the single phase supply big enough I'd just have a bigger rotary phase converter just don't have the supply so that's why I'm looking
We have solar panels & the installation feeds into the domestic side with a 240v inverter, There were no issues with connecting it to the 240v domestic side of the supply. The 3 phase supply just works, Its nice to be able to run lathes, mill & other machines as they came with no farting about with converters or changing motors.

I’m surprised there have not been any questions as to what power is needed?
Nearly all the motors in my workshop operate on 3 phase, but I simply use the single phase supply and a collection of VFDs. Nothing in my workshop is high powered, mind. I only use one machine at a time.
If you have space, a 3 phase solar array could be a beneficial adfition?

I've only ever experienced that with the jobsworths in the region that was covered by SEEBOARD which was then under EDF and is now under UKPN.
