Checking credit on your first-generation in-home smart meter display
To check if your smart meter display is a first-generation model, you can usually find a 'Secure' logo on the front or back.
You can see your last five top-ups on your smart meter.
Choose either electricity or gas from the Main Menu and they’ll be displayed with your current meter balance and how many days your energy will last.
This is only an estimated amount of time and it’ll change depending on how much energy you use.
