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.
