All appliances have a rating which indicates how much energy it uses. This is usually found on the base of the appliance or just inside the door on larger items. This is either written in Watts (W) or Kilowatts (kW). If it is in kW, multiply the figure by 1,000 and then enter into the calculator.

Your statement will tell you what type of tariff you are on. Click here to see where to find this.
