The data they transmit is encrypted, and energy suppliers only receive information about your energy consumption, not personal details. This makes smart meters highly secure and resistant to cyberattacks, with security measures that are continuously updated to address emerging threats.

Do Smart Meters Work During Power Cuts?

A common concern is that smart meters stop working during a power cut. While smart meters require power to function, they store data locally during outages and transmit it once power is restored. This ensures that accurate readings are sent to the energy supplier, even after a power outage.

Smart meters are designed to continue working as normal once the power comes back on, and they will not lose any data collected during the downtime. Some smart meters even have battery backups that allow them to send a "last gasp" signal to the network, helping energy companies identify and respond to power cuts more quickly.
