A smart meter will send an accurate reading of your exact energy use to the energy supplier either half-hourly, daily or monthly, it’s your choice. This does away with estimated bills – so you’ll only be charged for what you use.

You can see exactly how much energy is being used by a particular appliance – for example, each time you put the kettle on. This helps you monitor your energy use. It also helps you work out which appliances are the worst energy guzzlers and which ones are the most energy efficient.

If you can see how much energy you’re using, you’re more likely to change bad habits and hopefully reduce what you use. This is great for budgeting. Better energy habits could mean cheaper energy bills in the long run.
