What affects your electricity bill
Your usage rate (c/kWh)
The single biggest driver of your bill. Rates vary by retailer, distributor, and state. Comparing plans can find lower rates for the same usage.
Daily supply charge
A fixed daily charge (sometimes called 'service to property') that applies regardless of how much electricity you use.
Household size and appliances
Larger households use more electricity. High-consumption appliances (electric hot water systems, air conditioning, pool pumps, EV chargers) significantly increase annual costs.
Solar feed-in tariff (if applicable)
Households with rooftop solar can offset consumption costs with feed-in tariff credits. Higher feed-in tariff rates reduce net bills, sometimes substantially.
Network and distribution charges
A portion of your bill covers the cost of maintaining the poles, wires, and local distribution infrastructure. Network charges vary by distributor and region.
Market offer vs standing offer
Market offers from retailers can be significantly cheaper than standing offers (default tariffs). Consumers on standing offers may be paying more than necessary.
How to reduce your electricity bill
- 1
Compare and switch plans
Review your current plan and compare alternatives. Even moving from a standing offer to a competitive market offer can save hundreds of dollars per year.
- 2
Shift usage to off-peak periods
Running dishwashers, washing machines, and dryers at night or on weekends can reduce costs on time-of-use plans.
- 3
Improve home insulation
Draughts, poor window insulation, and inadequate ceiling insulation increase heating and cooling costs significantly. Addressing these can reduce energy consumption year-round.
- 4
Upgrade appliances
Older appliances (particularly refrigerators, hot water systems, and air conditioners) often use significantly more energy than modern equivalents. Look for high energy star ratings.
- 5
Consider rooftop solar
For households that own their home, solar panels can substantially reduce net electricity costs. Many Australian homes are well-suited to solar given the high solar irradiance across most of the country.
