The risk of smart metering functionality interruption, owing to the sunsetting of the 2G/3G networks.

By the end of 2033, 2G and 3G mobile networks are due to be switched off by telecommunications providers. As a result, smart meters that communicate via 2G and 3G mobile technology will require the installation of a new 4G compatible communications hub to allow them to continue to operate in smart mode. In most cases, smart meter consumers with these communications hubs will need to agree to a visit from an installer and be present at home at the time of installation. Therefore, consumer engagement will be an important part of ensuring the success of the exchange programme.
