The Government’s aim is that smart meters installed by one supplier can be operated by another so that consumers can switch energy supplier readily and retain the benefits of their smart metering service.
In some cases, when a consumer switches energy supplier, the new supplier will able to operate the meter in ‘smart’ mode. If the new supplier is not able to operate the meter in 'smart' mode, the meter will continue to accurately record energy consumption and can be used in 'traditional' mode, with meter readings taken manually.
Work is underway to make SMETS1 smart meters interoperable between energy suppliers through enrolment the Data and Communication Company’s (DCC) system. Ahead of enrolment in to the DCC, a number of industry parties are exploring approaches to enable more consumers to retain their smart services upon switching.
