I have 3 phase electricity with a dual rate meter. I would like a smart meter. I have asked my electrician and he says that it is very easy however the OVO technician who came to fit a smart meter said he couldn't do it. So I am paying over the odds for my electricity because OVO will not put me onto a single phase and install a smart meter

It's possible, @Dartmoor

You will need to get your 3 phase supply downgraded to a single phase supply, before a smart meter can go in. Here's the process:

- Get an electrician to check if downgrading the supply is possible (you've done this already - nice work).
- Arrange a date for (and pay for) a visit from your Distribution Network Operator (DNO), who will rewire your supply to make it a single phase set up.
- Liaise with OVO to make sure we can get an engineer to you on the same day that the DNO visit, to fit your smart meter free of charge: 0330 303 5063.

Hi,

I recently had one of your meter engineers pop over to fit a smart meter. As I have Phase 3 with eight cables running in and out of the current meter he was unable to assist. One of your competitors is currently offering this and as a loyal customer of OVO, I wanted to see whether OVO can help?

Have a look at my answer above your comment @JM71 - I moved your comment here as it's got more info on this process!
@Tim_OVO - your answer seems like a cop-out. If your premises is using a 3 phase supply properly ie feeds off of every phase to some sort of machinery etc then you can't realistically expect the customer to go to the expense of having 3 separate single phase supplies put in; surely that would mean 3 smart meters would be required to be installed.

We couldn't have a smart meter installed at work because of the lack of support for 3 phase installations (However we are with a different supplier)

Just my 2p worth, having spotted this conversation.

That's an important point @DataKnight. The absence of 3-phase supplies to the majority of our domestic properties means that we are suffering increasing losses at sub-stations due to phase imbalance.

In Germany, they are heading in the opposite direction. 3-Phase is becoming the norm. Unlike this country, they can foresee the massive savings that can be attained once EVs can be grid-connected using V2G chargers.

To be fair, this isn't OVO's problem. The British Energy Suppliers may only install Smart Meters which have been designed and tested in accordance with specifications drawn up by the Data Communications Company, and approved by Ofgem and GCHQ. No designs have been sought for 3-Phase meters.

One of the Ofgem-approved meter manufacturers, EDMI, already have a 3-phase Smart Meter design, the Mk10, which is installed widely in other countries. This could be adapted for GB use if DCC were required by Ofgem to have an option for a 3-phase Smart Meter.

Although there is currently no open public consultation on the portfolio of SMETS2 meters, there is no reason why you can't write to Ofgem and ask for their reasoning on why such a product isn't being sought. You might want to draw their attention to this discussion on the Forum.

I'm sure there are others here who would like to know of their response.
