It can be hard to spot if your energy meter is faulty, particularly if it’s wrong by a small amount. Unusual bills or meter readings are generally the best clue.

If you’re on a time-of-use tariff, you should be able to check the clock on your meter or see if the rate changes at the time of day it’s supposed to.

If you’re worried your meter is running fast, you could try turning off all your appliances and watching the meter. It shouldn’t still be registering significant amounts of energy.

If you suspect your meter is faulty, you should record regular meter readings. These will help prove your case.

You could also invest in an energy monitor. These let you view your real-time energy use.

Although an energy monitor isn’t a fool proof way of checking meter accuracy, they can be a good guide if you already have suspicions.
