How do I get a smart meter when I have a 3 phase supply?

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

Do OVO offer 3 phase smart meters?

 

3 phase (aka polyphase) installations in domestic properties are few and far between, so it's a minority of meter engineers across the country that have the skills required to complete these installations. There are also some technical challenges in making sure your job is allocated to an engineer with these skills but we are just as keen as you are to have Smart available for these sites ASAP.


If you have a three phase supply we’d would encourage you to book a smart meter appointment as normal online or over the phone on 0330 303 5063. 


This will then go through to a specialist team who will validate that it is single rate job and that an 3 phase engineer is available in your region. If this is the case, they will re-book your appointment with the right engineer. (So please bear in mind your appointment date/time will likely change, but we'll try to keep it the same where possible.)


Unfortunately, if you have a 2-rate meter or are not in an area covered by our current crop of 3 phase skilled engineers, you will need to continue with your heritage meter. We know this will be frustrating, so we are sorry about that, we are working to expand our coverage and by you flagging your interest to us, you are helping us shape where and when that coverage develops. - thank you!

This is great that folks are providing info. Planning permission arrived so remodelling can start - the electrics is a few months away but should be before Christmas.

Keep it coming!

As I don’t work for OVO@Uncle K - I can suggest a cheeky way of getting a 3-phase SMETS2 meter faster:

The first real-life installation of a 3-phase meter for a domestic customer is Good Energy.

Looking at the official response from within OVO that Tim has quoted above, it reads “… we won't be able to fully support these meters from other suppliers until that work is done, but we would still be able to communicate with them to get readings

That means you could ditch your existing OVO contract, switch to Good Energy on condition that they install your preferred meter, and then switch back to OVO.

Some unbiased community support there, that’s why a forum like this is best for customer service! I could never advise such a thing, and won’t comment on it here. 

 

@PeterR1947 :rofl: I gave Transparent the heads up on Friday that I was ‘offline’ this weekend (for once) as I had my 9 day old nephew to hang out with. So he knew he had a decent time window to work with. What a pro

 

What do we think, @Uncle K - and whatever you choose, please keep us update here!

Thanks for this and apologies for taking so long. I’m still prevaricating - and also waiting for more of timetable/schedule from my builder and electrician and solar panel installer as to when I need this by. I also need to look down at my shoes as I admit that I am not an OVO customer at the moment (gasp) and not a Good Energy customer either. My current supplier - cheapest at the time with reasonable service recommendations - is Bulb - but I’m waiting on reply from them on this subject - and I guess no news is bad news.

Cheers

This is an industry-wide issue @Uncle K and therefore needs airing here regardless of which Energy Supplier each of us has.

Let’s note that we’ve heard nothing more from Good Energy’s media staff since that first announcement of a 3-phase meter installation. That makes me wonder if the software support is really yet functional to provide accurate invoices. Remember that the “customer” for the initial installation is a senior manager at Good Energy!

 

I’d still like @Tim_OVO to confirm that I’m correct in my assumption that OVO only accepts new Solar Panel arrays that have been installed by a MCPS-registered company because they require the ROC (Renewables Obligation Certificate) in order to recover the annual income.

This affects my technical input to the Topic. I can conjecture some interim solutions which might help in the short term whilst the metering and billing gets resolved. But those are to no avail if @Uncle K has to recall an MCPS-certified installer to site every time he wants to make a change.

I’d also like to know if the OVO customers in the Woodhall Spa are who are on the Kaluza/Sonnen Battery Storage Trial are using SMETS2 meters and OVO’s new Billing System. Or have they had to be down-graded to SMETS1 meters, as has happened to the 400-odd sites on the V2G charger Trial?

All these pieces of information are needed if sites like @Uncle K ‘s are wanting to start installing renewable micro-generation hardware without getting their fingers burnt.

Have a look at this page which outlines:

 

How do I sign up for Smart Export Guarantee?

 

Just fill out our application form here. Then, email us your:

  • Proof of ID showing your full name – like a valid passport, driver’s licence, birth certificate, or firearms licence.

  • Proof of ownership for your installation – it can be a paid-in-full invoice, or a letter from your installer, building contractor or solicitor that shows you’re the owner. If the system was already installed when you moved into your home, you’ll need a Land Registry document, and a Fixtures and Fittings form – all clearly showing your name and your address.

  • Proof of address – like a utility bill, or a bank, building society or credit union statement from the last 3 months. You can also send us a council tax bill, an electoral register entry, or an HMRC tax statement for the current year.

  • An MCS certificate or equivalent – you should get this from your installer. You’ll see the certificate number at the top of the document (it’ll look like this: MCS-01234567-A). Or, you might get a Flexi Orb certificate (the number for this will be in the middle of the doc and it’ll look like this: Flexi-01234567890).

  • Distribution Network Operator (DNO) notification.

 

“Equivalent”, @Transparent - that indicates it’s not a prerequisite. Will you be wanting more clarity on this (he asks, knowing the answer already)?  

 

I’d also like to know if the OVO customers in the Woodhall Spa are who are on the Kaluza/Sonnen Battery Storage Trial are using SMETS2 meters and OVO’s new Billing System. Or have they had to be down-graded to SMETS1 meters, as has happened to the 400-odd sites on the V2G charger Trial?

 

I’m asking this question for you as well, leave it with me :)

Back with an update on this one - Are you a single rate 3 phase OVO member interested in upgrading to a Smart meter? 

 

If so we’re interested to hear from you - Send a PM to myself or @Tim_OVO for more details...:slight_smile:

I’m unsure if @Jess_OVO can answer that @Blastoise186 although I may be doing her a disservice.

It was a year ago when we poured over this problem on the Forum.

The issue wasn’t just that OVO needed to test out a 3-phase SMETS2  Smart Meter and train engineers to install them. The much bigger problem was the software required within the Billing System to accommodate polyphase operation.

If a domestic site has 3-phases operational it’s much more likely that they are simply splitting their loads between those phases rather than driving 3-phase equipment (as occurs in industry). They are also more likely to have storage and generation equipment. Dividing the export across the phases circumvents a couple of issues regarding the G99 certification with the DNO.
