SMETS1 Enrolment & Adoption Frequently Asked Questions

To help you understand what’s happening with the enrolment of first generation smart meters into the DCC’s secure network, we have collated a list of frequently asked questions below. As we progress we will keep adding to this list, so keep checking back for further updates.

Energy smart meters automatically send in meter readings to a consumer’s energy supplier and show the currently usage on a small in-home display, there are currently two main types of smart meter technology.

  • First-generation, also known as SMETS1, have been installed for many years, some of these meters will not allow changing energy supplier without losing the ability to send readings automatically.
  • Second generation, or SMETS2, meters began being installed in 2018 and allow you to switch seamlessly between energy suppliers as they are connected to a nation-wide secure smart meter network.

The government has put in place a programme to move first-generation meters onto this network, giving old meters the same benefits as new meters.

Ask your energy supplier if you are unsure what type of meter you have, or if it gives readings automatically.

To realise the full benefits of smart metering the Government decided that along with a new unified network and single smart meter standard, that all older smart meters should be migrated to this singular network rather than remaining on various unconnected networks. This will allow seamless energy supplier switching and smart operation no matter what smart meter generation you have or who originally installed it.

The DCC was given the role by Government of coordinating the ‘migrating’ of these meters onto the nationwide network. This has required working across the energy industry to make sure suppliers can bring their customers onto our network in a secure and seamless manner.

Its operation will only be improved. The display will continue to operate, and other functions like topping-up if it’s a prepayment meter will remain the same. The big difference will be its ability to securely and automatically send meter readers no matter which supplier you are currently on, or plan to switch to.

All SMETS1 meters will be migrated to the DCC’s system by the end of the rollout.  

It will be done over-the-air (OTA) meaning the new software will be delivered wirelessly without a visit from a technician. Most likely you will not be required to do anything, and you may not notice the change happening until your current energy supplier notifies you. There will be no disruption in your energy supply.

Though we appreciate you would like the added convenience of having your smart meter on our network – but we’d ask everyone to be patient. Meters will be moved gradually over the course of the rollout. 

Yes, it is safe. No, you will not lose power.

Because these meters are in people’s homes, and are so important to daily life, the programme has been designed to be extremely cautious. This means each meter type will be extensively tested and suppliers have been given advice to ensure no issues with supply or billing.

Our network has been built to the highest security standard which has been reviewed by the National Cyber Security Centre. It uses high levels of encryption, and the most important data passes over our network encrypted without the ability for the DCC to read it. Like before only your supplier can see how much energy you are using and when. We can only see all of your data with your explicate approval.

For the migration of dormant meters (meters not giving automatic readings) the DCC will play the lead role in managing the migration. For active meters, the consumer’s energy supplier has key role in supporting the migration, which the DCC will help manage. It will be the energy supplier setting the date, contacting customers if necessary, and ensuring all billings are in order.

They will also be accountable for ensuring prepayment customers do not lose supply during the migration. We have advised all suppliers to put measures in, such as temporality putting the meter in credit mode during migration, to ensure supply is not lost during migration.
