It's important to know the charges on your energy bill and tips to help you save money and energy. 

Your bill is calculated using two charges.

  • A supply charge which is a fixed cost per day
  • A usage or consumption charge which is calculated by how much electricity you use and when you use this energy. This is a variable charge and is measured by your meter.

Together, these charges form your tariff.

So how can you save money?

There are many ways to save money on energy.

One way is using less electricity and picking the best times of day to use electricity.

For example, customers may be charged different rates depending on the season or time of day that power is used. Using more electricity during cheaper times can help you save money.

Another is to shop around for a cheaper energy contract.

Just remember, the supply charge stays the same even if you use less energy, but you can search for a provider that charges a lesser amount.

Why is your bill higher?

If you notice your bill is higher than the last, it could be for several reasons:

  • changes in the weather and use of heating or cooling
  • moving to a house that is less efficient
  • having more people in your home
  • a balance brought forward from your previous bill
  • changing your energy plan
  • doing renovations
  • using appliances that use more energy.

Take some time to understand your energy bill and look for better deals. With a little effort, you can save money and help protect the planet.
