We can connect to any SMETS2 smart meter and some SMETS1 smart meters (such as those made by the brand Secure™). We will automatically try to connect after you've switched but may still ask you to send your first set of meter readings manually.
If we are unable to connect to your SMETS1 meter, it will become "dumb" and work like a normal meter so you'll need to give us manual meter readings. Across the industry, SMETS1 meters are in the process of being upgraded to stay smart when you switch supplier. We will be in contact to let you know when we're making your meter smart again.
