Quick answer
Most SMETS1 smart meters can be upgraded remotely through the DCC enrolment and adoption programme, so they behave more like SMETS2 meters when you switch supplier. In many cases no engineer visit is required, but your supplier can confirm status, timing, and whether replacement is needed.
What does a SMETS1 to SMETS2 upgrade mean?
If your smart meter was installed before the UK moved to SMETS2 as standard, it may be a SMETS1 meter. Some SMETS1 meters historically lost smart functions after switching supplier.
The DCC enrolment programme is designed to connect eligible SMETS1 meters to the national network so smart functions are more reliable across suppliers.
Do I need to request a smart meter upgrade myself?
Often no. Many upgrades are scheduled and processed by suppliers as part of ongoing rollout.
You should still contact your supplier if:
- smart readings stopped after switching,
- your in-home display has been offline for a long period,
- you are unsure whether your meter has already been enrolled.
How can I check whether my meter is SMETS1 or SMETS2?
Use one or more of the following:
- installation date (older installations are more likely SMETS1),
- supplier account or bill details,
- direct supplier confirmation via support.
Will I need an engineer visit for the upgrade?
Many upgrades are remote. In some cases, replacement or site work may still be required, depending on meter model and connectivity constraints.
Your supplier should confirm:
- current upgrade status,
- expected completion timeline,
- whether a visit is required.
Why does this upgrade matter before switching supplier?
Once your meter setup is stable, switching is usually smoother:
- smart readings are less likely to drop,
- billing continuity is easier to maintain,
- you can compare tariffs with more reliable usage data.
If you are planning a switch, you can begin with Compare Energy Prices, then review How Taupia Works and Supported Suppliers.
