If you were previously with British Gas, and they had installed a smart meter, here are some instructions on how to read the meter:
Electricity - Press the green ‘A’ button in the top right-hand corner to step through the displays, until you reach a screen that says ‘TOTAL ACT IMPORT’. The number on this screen is your electricity meter reading.
Gas - Press the red button to turn the screen on. Then press the red button again until it says ‘meter index’. The number on this screen is your gas meter reading.
Unfortunately British Gas have made it impossible for other suppliers to remotely read their meters. This is something that we expect to change in late 2017 - we will keep you posted on how this develops.
