A smart electricity meter uses electricity from the supply that goes into your home - so it won't record on the meter and you won't be billed for the electricity it runs on.
If power to your smart electricity meter is interrupted, it'll save all your information (including the data from your in-home display), so it can be restored when the power is back.
These are powered by a battery that’s built into the meter. Due to safety reasons you won’t be able to access it. The battery is designed to last more than 10 years before needing a replacement but when that time comes, the gas meter will alert our systems. We'll then contact you to arrange an appointment to replace the battery.
