First Generation Smart Meters (SMETS1) do not currently 'act smart' when you switch suppliers. This means that after the switch, your meter will continue to track the energy usage but lose its smart functionality (such as in-home display, ability to send meter readings directly to the energy supplier).
To keep the bills accurate, your new supplier will regularly ask for meter readings. The quickest way to submit this information is by using your Switch dashboard. Simply select the 'Meter readings' function from the sidebar on the left of your dashboard, enter the figures, and our system will automatically send a notification to your energy supplier!
Most energy suppliers can now connect to the Second Generation Smart Meters (SMETS2). If your new supplier can connect to the meter, they will be able to take remote readings and update your in-home display. The process is usually completed within 14 days of your supply going live and the supplier will contact you if they need any more information.
How do I know if my meter is SMETS1 or SMETS2?
To be 100% sure, the best thing to do is to check the user guide or to contact the supplier who installed the meter. You can also look at your electricity meter. If the serial number starts with 19P, this indicates a SMETS1 meter. If it starts with 19M, then this means you have a SMETS2 meter.
