How to Reduce Your Electricity Bill in Australia (Practical 2026 Guide)

This is the single biggest lever. Most people set up their electricity account when they moved in and haven't touched it since. Energy companies count on this - they offer 'loyalty discounts' that are often much less competitive than what they're offering new customers.

Government comparison tools are free and independent - use Energy Made Easy (energymadeeasy.gov.au) in NSW, VIC, QLD, ACT, SA, and TAS, or Victorian Energy Compare (compare.energy.vic.gov.au) if you're in Victoria. In WA, Synergy has a regulated tariff but still offers a few plan options worth checking.

Look at the unit rate (cents per kWh) and the daily supply charge. Sometimes a plan has a low unit rate but a high daily charge, making it worse for low-use households. Model your actual usage against each plan.

Every Australian state and territory offers electricity rebates - many are unclaimed simply because residents don't know they exist:

• NSW: Low Income Household Rebate ($285/year), Medical Energy Rebate, Life Support Rebate
• VIC: Power Saving Bonus ($250 one-off for switching plans, when available), Winter Gas Concession, Healthcare Card Concession
• QLD: Electricity Rebate ($372.20/year for eligible households), electricity bill relief credits
• SA: Cost of Living Concession, Energy Bill Relief Fund
• WA: Hardship Utility Grant Scheme, Dependent Child Rebate
• Federal: Energy Bill Relief Fund - check with your state government for current round availability
• Solar households: check that your feed-in tariff is still competitive - many legacy rates have been cut significantly

Check your state government's website or call your energy retailer to confirm which concessions you're eligible for.

Understanding where your electricity actually goes helps you prioritise. In the average Australian home: heating and cooling accounts for roughly 40% of electricity use, water heating around 25%, appliances and electronics about 30%, and lighting around 5%.

Targeting heating/cooling and water heating will have the biggest impact. Everything else is incremental.

Your air conditioner is almost certainly your most power-hungry appliance. Small changes here save real money:

• Set your thermostat to 18–20°C in winter and 24–26°C in summer. Each degree of difference in a cooled/heated room adds roughly 10% to running costs.
• Use ceiling fans before turning on AC. A fan costs around 2 cents per hour to run vs 20–40 cents for reverse-cycle AC.
• Close doors and vents to rooms you're not using - don't heat or cool your whole house when you're in one room.
• Service your aircon annually. Dirty filters reduce efficiency significantly.
• Use draught stoppers on doors and windows - a $10 fix that prevents significant heat loss.
• Electric blankets use roughly 70–120W vs a heater at 2,000W - consider swapping for cold nights.

Water heating is 25% of the average electricity bill. Options to reduce it:

• Set your hot water system to 60°C (minimum for safety) rather than leaving it at the factory default of 65–70°C
• Wash clothes in cold water - modern detergents work just as well
• Fix dripping hot taps immediately - a slow drip wastes significant energy and water
• Time your showers - each minute of hot shower uses roughly 2.5 cents of electricity
• If you're on a time-of-use tariff, use a timer to heat your water during off-peak hours (typically 10pm–7am)

Standby power is a silent drain - it typically accounts for 5–10% of your electricity bill:

• Turn off TVs, gaming consoles, and entertainment systems at the wall when not in use
• Unplug chargers when not actively charging - they draw power even when idle
• Run dishwashers and washing machines on eco/cold cycles
• Only run dishwashers and washing machines when full
• Upgrade old fridges - a 10-year-old fridge can cost $150–$200 more per year to run than a modern efficient model
• Use a smart power board with a master socket to automatically kill standby power when your TV is off

For homeowners, solar remains one of the best long-term electricity cost reducers in Australia - especially in states with high sun exposure (WA, QLD, SA). A typical 6.6kW system costs $6,000–$10,000 after government incentives and can reduce electricity bills by $1,000–$1,800 per year depending on your usage and feed-in tariff.

However, if you're renting or don't have the capital, focus on the low- and no-cost strategies above first - they can save $300–$600 per year with zero upfront investment.
