Smart meters will replace your existing gas and electricity meters and will make it much easier to manage your energy. You won’t have to submit readings anymore as this will be done automatically, which also means you’ll never receive another estimated bill.
You’ll also have more ways to keep track of your energy usage, starting with your IHD which will let you see in near real time how much you’re using. Why not try turning some appliances on and off to see how they affect your usage – you could find some simple ways to save!
