National enrolment and adoption (E & A) of SMETS1 smart meters onto the Data Communications Company (DCC) - Your Guide

The SMETS1 smart meter enrolment process - your guide

If you had a first-generation smart meter installed before 2019, you may have encountered problems such as when trying to switch energy suppliers. This is because not all suppliers could communicate with every smart meter.

To fix this issue, a national remote upgrade was done. Any SMETS1 meters that have been updated can share your usage data with any energy supplier, just like SMETS 2 meters do.

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

Why did smart meters need to be updated?

The government decided to create a single smart meter data network to make the most of smart meters. This network helps smart meters work better with all energy suppliers, improving grid efficiency and helping everyone reduce carbon emissions.

How did the update happen? 

Your smart meter was updated wirelessly, eliminating the need for an engineer's visit and ensuring there was no disruption to your energy supply.

When was my meter enrolled?

This table shows the previous time frames depending on the meter manufacturer. 

If you’re not sure if your meter has been enrolled, you can check this via the smart meter checker tool set up by the DCC so you can see if you’re meter has been successfully enrolled and updated. Check that out here.

Was the update optional?

This update wasn’t optional because all SMETS1 meters needed to be updated and connected to the Data Communications Company (DCC) by September 2022. It was a government initiative so everyone had to do it – not just OVO customers. Any meters that weren’t successfully enrolled are still being worked on between the DCC and suppliers.
