The SMETS1 smart meter enrollment process - Your Guide

 

If you had a first-generation smart meter installed (this was usually before 2019), you might be aware of the limitations of this version of smart meters when it comes to switching suppliers. As not all suppliers were able to communicate with all meter models this meant that you might lose smart functionality of your meters when you switched. In order to rectify this a national remote upgrade took place to make sure all SMETS1 meters will be able to communicate your smart meter usage data to all energy suppliers, much like SMETS 2 meters

 

This process is known as ‘Enrollment and Adoption’ (E&A) and is being managed by the Data Communications Company (DCC)
 

 

Why do these smart meters need to be updated?

 

To get the full benefits of smart meters, the government has decided that there should be one new unified smart meter data network. This makes smart meters work more effectively with all energy suppliers, improving the efficiency of the grid and helping us all to cut carbon emissions.

Once your SMETS1 smart meter has been updated to this single network, you’ll also be able to switch suppliers without your meter losing its smart features. Smart meters automatically send meter readings to your energy supplier. This means your bills are more accurate, and you can see how much energy you’re using online – or on your In-Home Display (IHD)

 

 

How did the update happen? 

 

Your smart meter was updated wirelessly, so you don’t need a visit from an engineer – and there won’t be any disruption to your energy supply.

 


What timescales to expect for my meters to be enrolled?

 

This table shows the expected upgrade time frame depending on the Meter Manufacturer.

How can I easily identify if the meter is Secure?

 

Secure Electric Meter Serial Numbers will start with XXP (eg 18P) and Gas Meter Serial Numbers will start with G4P. You can find the Meter Serial number on the front of your meters.
 

 

Can a S1 Secure meter go through E&A with no signal?

 

The short answer to this is no. A S1 Secure meter must be in communication with us in order for OVO to migrate the meter. Check to see if your meter has WAN here
 

 

Will I receive an email when my meter is being upgraded?

 

The Data Communications Company (DCC) is updating SMETS1 meters in batches, we receive notification of which accounts will be updated 15 days in advance which gives us time to send an email or letter to  let you know. This includes a data protection statement for obtaining and using your meter readings.

 

If this update is successful then we’ll send you another email or letter to let you know. If it’s unsuccessful we’ll let you know and the DCC will try and update the account again - we'll let you know if and when the update is successful. We unfortunately have no control over who gets upgraded and who doesn't, this is decided by the DCC.

 

 

Can all meters go through E&A?

 

There'll be some meters that cannot go through E&A and will need replacing such as older EDMI meters. DCC publish their lists on what model combinations will be eligible as they complete their testing. Most testing for Aclara, Elster, Itron and Secure has been completed and we are working our way through the migrations of those meters.
 

 

Are there any Exceptions to the E&A process?


There’ll be many scenarios where the process is not so straightforward. All exceptions are under review currently.
 

 

Is the update optional?

 

This update isn’t optional because all SMETS1 meters need to be updated and connected to the Data Communications Company (DCC) by September 2022. It’s a government initiative so everyone has to do it – not just OVO members.

 

How can I check if my meter has been updated?

 

You can check whether your meter has completed the enrolment process using this online tool.

Hello,

We are looking at moving across to ovo from british gas soon, we currently have a Landis+Gyr E470 and our meter still hasn’t been upgraded, at least the smart meter check page keeps saying it can’t find the meter anyway.

My question is, when I move across to ovo, the meter will obviously go dumb, is there a rough timeline for these meters to be upgraded or is it still just a wildcard as to when it may work again?

I don’t mind it going dumb just to have the chance to get away from british gas, but I would like it to eventually work properly again preferably in the not too distant future.

Cheers


Hi @Sloth its been suggested that if they can’t upgrade the S1 meters by the end of the year they will be swapped out for a new meter - having said that, it was meant to be completed last year


Howdy @Sloth !

Should be either within 12 months, or if that fails OVO would replace it with an S2 setup.


Hi there!

In a few months I’m going to be moving into a flat that’s got a SMETS1 meter originally installed by SSE (It’s an Alclara SGM1311 with the SGC1311 communications module on the top). The current owner of the property is with Ovo and the meter is automatically providing meter readings.

 

Based on the fact it’s providing meter readings to Ovo, does this mean that it’s definitely gone through the E&A process?

 

We put the MPAN into into https://smartmetercheck.citizensadvice.org.uk and it comes up with:

Your electricity meter isn’t working in smart mode

You have a first generation (SMETS1) electricity meter.

Your supplier can't support it in smart mode yet.

You should take regular meter readings and send them to your supplier. If you don’t, they’ll send you estimated bills.

 

However, I’ve heard that tool is not completely reliable.

Additionally, as this is all a bit new to me, is a SMETS1 meter that’s gone through the E&A process as good for switching to other suppliers as a SMETS2 meter? Or will there still be some suppliers that can’t support it?


Yup! Aclara meters went through E&A some time ago and work like a SMETS2. All suppliers should support it. If it breaks, it can be replaced with an S2.

Source: I had one myself.

Just FYI, my meter went through E&A a few months ago. It started providing data to OVO and third-party data handlers within a couple of days, but the CA tool still tells me the same as you’re seeing. So yes, the tool is unreliable as regards some SMETS1 meters. 


I have, I believe, a SMETS1 meter (installed by Ovo in the early days of the meter rollout), and one of those gloriously slow and hard to understand monochrome display devices.

From what I can read it sounds as if I just need to sit tight and wait to just be told about any chance to upgrade. Is that the case?


Hi @dartiss ,

I’m one of the forum volunteers.

I think you’re talking about a Secure Liberty meter and a Secure Pipit 500 IHD, is that right? If so, it should in theory have been migrated to DCC by now. Try https://smartmetercheck.citizensadvice.org.uk/ as that can tell you. Be careful, it lags behind quite a bit!


Thanks. You’re right - it is those models.

Where I will find my MPAN number on my online account?


You can grab it from any of your bills under https://account.ovoenergy.com/billing-history but you’ll need to download them. MyOVO no longer seems to show them within the portal itself, probably because too many folks were accidentally leaking their MPAN on forums like this one.


Thanks - found it.

So, that website told me…

Your electricity meter's working in smart mode

 

Which I already knew. It confirms it’s a SMETS1 too.

But that didn’t answer my original question, unless I missed something.


If that tool says the meter is in Smart Mode, it’s already had the upgrade. If it hadn’t yet been done, it’d likely be in the queue.

Those that fail to upgrade at all become eligible for a free S2 replacement.


When you say “upgrade”, do you mean it’s now SMETS2?


No, it remains SMETS1. The upgrade as many people call it, are firmware updates that allow S1 meters to migrate to DCC and then actually getting migrated to DCC. As they’re ultimately still S1 hardware and firmware, they remain S1 meters.

I like to call those ones SMETS1+ or S1+ for short as they run like an S2.


So, the next question is about an upgrade to SMETS2. When is that likely to happen and do I need to do anything about it?


No need. If things are working no further action is required.


So, despite lots of other companies not supporting my meter (as a smart meter anyway), there are no plans to upgrade it? I guess there’s no incentive for Ovo to do it but it is a bitter pill for being so keen to be on the smart meter rollout.


The upgrade is done mostly by DCC in the background. There’s no hardware replacement involved. OVO will/would have let you know when it was taking place via email.

There’s no way to speed it up I’m afraid.


The real problem that you’ve got is that over 50% of suppliers that installed S1 Secure Liberty meters are now dead for one reason or another. If they were still around, you could have switched to any of those freely while retaining Smart features even before DCC existed.

Alas, they mostly went bust or got swallowed by someone else.

These are the ones that used to install them:

  • Utilita Energy Limited
  • Co-operative Energy Ltd - dead (went bust, Octopus took over)
  • First Utility Ltd aka Shell Energy - basically dead now because Shell wants out
  • Electricity Plus Supply Ltd t/a The Utility Warehouse
  • E (Gas & Electricity)
  • Spark Energy Supply Limited - dead (went bust)
  • Eversmart Energy Ltd - dead (went bust)
  • EON Energy (now E.On Next but limited support for unmigrated meters)
  • Robin Hood Energy Limited - dead (went bust)
  • Ecotricity
  • Bristol Energy - dead (went bust)
  • OVO Energy
  • Our Power Energy Supply Ltd - dead (went bust)
  • Octopus Energy

Out of those that remain, if you have S1 Secure that’s not migrated and want it to keep working… You’re basically limited to just OVO and Octopus if you want Pay Monthly. The others don’t really support Pay Monthly or aren’t really in a position (in my personal opinion) to take such customers on.

If you want PAYG, then your options would be either OVO, Utilita, ecotricity or E as the only four that I know of which do PAYG and have full support for unmigrated S1 Secure.

That’s what I’ve got, too, installed in early 2017. I’ve nothing to compare with, so I’ve not noticed that dear little Pipit being particularly ‘slow’ - in what respect? I see the last half hour’s usage within seconds of the half hour ending. 

When you’ve found your MPAN and plugged it into the CA tool, note that it’s not to be relied on, at least for Secure meters. It still claims:
 

Your electricity meter isn’t working in smart mode

You have a first generation (SMETS1) electricity meter.

Your supplier can't support it in smart mode yet.

 

when in fact it’s been working as intended since it was enrolled and adopted (‘E&A’) by DCC back in February. Mine is electricity-only, so on the Pipit’s History screen, the Usage button shows the actual meter reading. I understand that many more modern IHDs don’t show the meter reading, but I’m sure @Blastoise186 will put me right if that’s not the case. 

I don’t think you’ll be able to get a replacement meter if the one you’ve got is working properly, unless it still hasn’t been E&A’d by the end of this year. Be careful what you wish for!

 


Some modern IHDs can show the meter readings, such as the Chameleon IHD6/IHD7, Hildebrand Bright and Geo Trio II models. Others… Not so much glares at IHDL.

Interesting, we have seen that before where the citizens advice tool appears to  use data that takes a long time to update. 

 


Hey @Olu,

 

Welcome to the OVO Online Community,

 

I can see @Blastoise186 and @Firedog have already given some helpful advice here. Just wanted to add that the following topics may have some helpful advice:

 

 


… the citizens advice tool appears to  use data that takes a long time to update. 

 

@Jeffus I’m not so sure that this has to do with the time it takes to update. It’s more likely that it’s something systemic at DCC, which seems to have problems with these Secure Liberty meters. It is after all 18 weeks since mine was E&A’d, and the CA tool is still giving the wrong message. It’s bit cryptic, though, so I can’t rule out that the hiccup is at OVO. This is what it says:
  

You have a first generation (SMETS1) electricity meter.

Your supplier can't support it in smart mode yet. You should take regular meter readings and send them to your supplier. If you don’t, they’ll send you estimated bills.

If you normally top up using an app and you're no longer able to, talk to your supplier.

If you want your meter to work in smart mode you can switch to a supplier who can support your meter in smart mode.

Your supplier is also working to upgrade your meter to smart mode. They'll let you know when they’ve done this. They'll do it remotely, so you won't need to do anything to your meter.

  
It’s as if the tool thinks that it’s OVO that has the problem (“you can switch to a supplier who can support your meter in smart mode.”), even though everything is working more or less as expected. 

 

 


Ah @Firedog thats very useful. Mine is a Secure Liberty too and the CA tool tells me I’m with OVO even though I switched last month.

The fog is clearing…
