This leaflet explains how the smart metering system works from late 2016, when a new shared smart metering national infrastructure is in place. Some energy suppliers are already offering smart meters using their own systems and technologies.
The diagram below illustrates the main parts of the smart metering systems showing the equipment and communications within energy consumers’ homes. It shows the organisations that will use the information provided by smart meters (DCC Service Users), and the system provided by the Data and Communication Company (DCC) which will link these organisations with the smart meters.
