Will my smart meter stop working if I switch energy supplier?


No. Your smart meter will continue to accurately record your gas and electricity usage. However, if you’re considering changing energy supplier, it’s best to check if your new supplier can support smart metering technology before you agree to switch.
In this early stage of the rollout, some people with SMETS1 type meters may find that if they switch supplier, they need to start sending meter readings again in order to get an accurate bill.
This is just a temporary situation. A secure national communications network for smart meters is being set up. Once SMETS1 meters have been enrolled into this network they will become interoperable between suppliers and will once again deliver their full benefits.
