We can give you the most accurate bill estimate when you provide details of your energy usage from a previous bill. If you don't have a bill handy, we use the average of similar households in your area to give you an estimated monthly cost.
Our rates exclude GST as this is the industry standard. However, we've included the GST in your summer and winter estimates to give you a better idea of your total monthly bill.
