Reducing household energy costs doesn’t require an overhaul. From switching to a better plan to adjusting everyday habits, small changes add up to real savings
Reducing household energy costs is something most Australian families can achieve without spending a cent on upgrades. The biggest savings usually come from understanding how energy is priced, when it is consumed, and whether the current plan still makes sense. Bills have risen sharply across the country, with the Australian Energy Regulator confirming average residential electricity prices increased by over 20% between 2022 and 2024. The steps below address the most common and correctable causes of overspending.
1. Compare and Switch to a Better Energy Plan
Switching to a more competitive plan is one of the fastest ways to reduce a household’s quarterly payments. Many Australians remain on default market offers, which are typically the most expensive options available. Those exploring utility connection services can compare electricity and gas plans across multiple retailers in one place, making it straightforward to identify a better rate without spending hours on hold or navigating individual provider websites.
Key things to compare when reviewing plans:
| Feature | What to Check |
| Usage rate | cents per kilowatt-hour (c/kWh) |
| Daily supply charge | fixed cost regardless of usage |
| Discounts | conditional vs guaranteed savings |
| Contract terms | exit fees or lock-in periods |
| Feed-in tariff | relevant if solar panels are installed |
2. Understand Your Tariff Type
Not all electricity tariffs work the same way. Choosing the wrong one for a household’s routine can add an ongoing cost that often goes unnoticed.
There are three main tariff structures available to most Australian households:
● Flat rate: a single price per kWh, regardless of the time of day
● Time-of-use (TOU): cheaper rates during off-peak hours, higher rates during peak periods, typically 3 pm to 9 pm on weekdays
● Demand tariff: charges based on the highest level of power drawn during a billing period, common in some states
3. Manage Heating and Cooling Smarter
Heating and cooling account for roughly 40% of a typical Australian household’s energy use, according to the Department of Climate Change, Energy, the Environment and Water. That makes it the single largest opportunity for savings.
A few adjustments can make a measurable difference:
● Set heating to 18–20°C in winter and cooling to 25–27°C in summer. Each degree above or below that range adds approximately 10% to the relevant running cost.
● Use ceiling fans before reaching for the air conditioner. A fan costs a fraction of a cent per hour to run.
● Seal gaps around doors and windows to reduce heat loss in winter and heat gain in summer.
● Close curtains and blinds during the hottest part of the day to reduce the cooling system’s load.
4. Switch Off Standby Power
Appliances left on standby continue to consume electricity, even when they appear to be off. Across a full household, standby power can account for up to 10% of total electricity use.
Power boards with individual switches make it easy to cut power to entertainment systems, phone chargers, and office equipment without unplugging each device separately. Turning off appliances at the wall before bed takes seconds and adds up over a billing cycle.
5. Upgrade to Energy-Efficient Appliances
Older appliances, particularly fridges, washing machines, and water heaters, draw significantly more power than current models. The Star rating system makes comparison straightforward: each additional star represents roughly 10% less energy consumed per year.
A fridge running 24 hours a day, seven days a week, is one of the highest ongoing costs in any household. Replacing a 10-year-old model with a 4-star equivalent can reduce that appliance’s annual running cost by $100 or more, depending on usage and local electricity rates.
6. Reduce Hot Water Costs
Water heating is the second-largest energy expense in most Australian homes, behind space conditioning. Three practical adjustments reduce this cost without affecting comfort:
● Lower the water heater thermostat to 60°C. This level is the safe minimum recommended by Australian standards and eliminates energy wasted heating water beyond what is needed.
● Wash laundry in cold water. Modern detergents perform equally well at cold temperatures, and the savings per cycle are immediate.
● Fix leaking hot water taps promptly. A slow drip from a hot tap wastes both water and the energy used to heat it.
7. Consider Solar if the Conditions Are Right
Rooftop solar remains one of the most effective long-term strategies for reducing electricity costs in Australia. As of 2024, more than 3.5 million Australian homes had solar panels installed, according to the Clean Energy Regulator.
The financial case depends on a few variables:
● Roof orientation: north-facing panels generate the most output in Australia
● Feed-in tariff rate: what the retailer pays for excess electricity exported to the grid
● Daytime usage: households that use more power during the day capture more value directly, rather than exporting at lower feed-in rates
Wrapping Up
Reducing household energy costs does not require a complete lifestyle change. Most of the savings available come from a handful of practical decisions: reviewing the current plan, adjusting how and when appliances run, and addressing the highest-cost areas first. Starting with a plan comparison costs nothing and takes minutes. For households that have not reviewed their energy arrangement in the past 12 months, that is the most logical first step.
