Cut Your Energy Bill This Winter: 12 Tips That Work

Kmart Winter 2026 Home Finds Worth Your Money">tuckara.com/post/seasonal-australian-budget-recipes-2026" title="Seasonal Australian Budget Recipes 2026: Fresh and Affordable">Australian energy prices have risen sharply in recent years, and winter is when the bill most clearly shows it. Heating is the biggest contributor — but it's not the only one. These 12 strategies address the full picture, from heating efficiency to hot water to appliance habits, and together they can meaningfully reduce your winter energy bill.

1. Set Your Heating to 18–20°C, Not Higher

Every degree above 20°C adds approximately 10% to your heating costs. Most Australians heat to 22–24°C when 18–20°C, with appropriate clothing and throws, is perfectly comfortable. Set your thermostat and leave it — don't let it drift up over the course of the evening. This single change reduces heating costs by 20–40% for most households.

2. Heat the Room You're In, Not the Whole House

Close doors to unused rooms and heat only the occupied space. A portable electric heater in the room you're using costs less to run than a ducted system heating the whole house. For most Australians, a 2,400W oil column heater ($50–$80 from Kmart) in the living room costs less to run per evening than whole-house ducted gas.

3. Use Heavy Curtains or Thermal Liners

Up to 40% of heating energy is lost through windows. Heavy lined curtains or thermal curtain liners (Kmart and Spotlight both stock these) significantly reduce heat loss. Close curtains at dusk — don't wait until you go to bed. The difference in a room with heavy curtains versus uncovered windows is significant and the saving is immediate from the first cold night.

4. Draught-Proof Your Home

Gaps under doors, around window frames and through old skirting boards lose significant heat. Draught snakes at the base of external doors ($5–$15 at Kmart or DIY with a rolled towel) are the quickest fix. Bunnings stocks door seal strips and window foam tape for more permanent solutions — total cost $20–$40 for a whole house and the saving is ongoing every winter.

5. Reduce Hot Water Temperature

Most hot water systems are set to 70°C — far hotter than necessary. Reducing to 60°C (the minimum safe temperature to prevent legionella) reduces hot water energy use by 5–10%. For electric systems this is usually a dial on the unit itself. For gas systems, consult your manual or plumber.

6. Wash Clothes in Cold Water

Washing in cold water instead of warm or hot uses 80–90% less energy for the wash cycle. Modern detergents are formulated to clean effectively in cold water. For most household laundry, cold washing is equally effective and dramatically cheaper over winter when you're doing more loads.

7. Use Your Dishwasher Efficiently

Run the dishwasher only when full. Use the eco or half-load setting if available. If your dishwasher has a heated dry function, turn it off and air-dry instead — this alone saves 15–50% of the dishwasher's energy use per cycle.

8. Switch Off Standby Appliances

Australian households spend an estimated $100–$150 per year on standby power — appliances left on standby rather than switched off at the wall. TVs, gaming consoles, phone chargers left plugged in, microwaves with clocks — all draw continuous power. Switching off at the wall when not in use reduces standby costs to near zero. Smart power strips from Kmart ($15–$25) automate this for entertainment systems.

9. Compare Your Energy Plan

Canstar, Compare the Market and the government's Energy Made Easy website let you compare current energy plans in your state. Most households on standard variable rates pay 15–25% more than the best available plan. Switching takes 20 minutes and the saving is automatic every bill. Review annually — plans change and your circumstances may have changed.

10. Use the Microwave and Air Fryer Over the Oven

A full-size oven uses 2,000–3,500W and takes 10–15 minutes to preheat. A microwave uses 700–1,200W and is instant. An air fryer uses 1,200–1,800W and takes 2–3 minutes to preheat. For anything that fits — reheating, roasting vegetables, cooking proteins — the microwave or air fryer uses 50–70% less electricity than the oven.

11. Shower Shorter and Cooler

Hot showers are appealing in winter but expensive. Each extra minute in the shower adds to both water heating costs and water bills. A 4-minute shower instead of 8 minutes saves approximately $200–$350 per year per person in combined water and energy costs. A shower timer ($5–$10 at hardware stores) makes the change automatic and painless.

12. Check You're on the Right Tariff

Time-of-use tariffs charge different rates at different times of day — cheaper off-peak (typically late night and early morning), more expensive at peak times (4–9pm on weekdays). If you can shift energy-intensive tasks (dishwasher, washing machine, EV charging) to off-peak hours, you can reduce costs significantly without using less energy. Contact your retailer to check whether a time-of-use tariff suits your household's patterns.

Advanced Heating Strategies That Save Money

Zone Heating with Portable Options

Instead of running ducted heating throughout your home, consider targeted heating solutions. A quality oil-filled heater like the DeLonghi Dragon4 (around $199 at Harvey Norman) or the Dimplex 2.4kW Oil Free Column Heater ($179 at Bunnings) can heat a single room efficiently. These use roughly 2000 watts compared to ducted systems that often consume 3000-6000 watts heating multiple unused areas.

For smaller spaces, the Dyson Hot+Cool range ($699-$899) offers precise temperature control and doubles as a summer fan. While the upfront cost is higher, the energy efficiency often pays for itself within two winters for frequent users.

Smart Thermostat Investment

Smart thermostats like the Google Nest Learning Thermostat ($399) or the more budget-friendly Honeywell T6 Pro ($249) learn your routine and automatically adjust temperatures when you're away. Users typically report 10-15% energy savings, meaning the device pays for itself within 18 months for most Australian households.

Hot Water System Optimisation

Temperature and Timer Adjustments

Most hot water systems are set to 65-70°C by default, but 60°C is perfectly adequate and safer for households with children. Reducing your hot water temperature by just 5°C can cut water heating costs by 6-10%. If you have an electric system, installing a timer (around $150-$200 from Bunnings) ensures it only heats during off-peak tariff periods.

Insulation Upgrades

Hot water pipe insulation costs just $15-25 for a full house kit from Bunnings but can reduce heat loss by up to 40% on exposed pipes. The foam sleeves are easy to install yourself and particularly effective if your hot water system is in an unheated area like a garage or laundry.

For storage systems, an insulation blanket ($49-$89 depending on size) wraps around your tank and can reduce standby heat losses by 25-40%. This is especially worthwhile for older systems or those located outdoors.

Appliance-Specific Money Savers

Washing Machine and Dryer Efficiency

Switching to cold water washing saves approximately $115 per year for an average family. Modern detergents like OMO Cold Water ($8.50 at Coles) or Earth Choice Cold Water Laundry Liquid ($4 at Woolworths) are formulated to work effectively in temperatures as low as 15°C.

For drying, wool dryer balls ($12.95 for a set of six from Kmart) reduce drying time by 20-30% by improving air circulation. They're reusable for years and eliminate the need for fabric softener, creating additional savings.

Refrigerator and Freezer Optimisation

Your fridge works harder in winter due to the temperature differential with heated indoor air. Keep your fridge at 3-4°C (not 1-2°C) and your freezer at -15°C to -18°C. Each degree colder than necessary increases energy consumption by 5%.

Check door seals regularly — the paper test works well. Close a piece of paper in the door; if you can pull it out easily, the seal needs replacing. Replacement seals cost $30-60 but can reduce fridge energy consumption by 10-15%.

Lighting and Electronics Winter Considerations

LED Bulb Upgrades

With longer winter nights, lighting costs increase significantly. If you haven't already switched to LEDs, prioritise the most-used rooms first. ALDI regularly stocks 9W LED bulbs (equivalent to 60W incandescent) for $4.99 each. A family replacing 20 bulbs typically saves $180-220 annually on electricity, plus bulb replacements.

Smart Power Boards

Standby power consumption increases in winter as we spend more time indoors using electronics. Smart power boards like the Jackson 6-Outlet Smart Power Board ($79 at Big W) automatically cut standby power to secondary devices when you turn off the main device (like your TV). This addresses the "vampire load" that costs Australian households $100-150 annually.

Practical FAQ Section

How much can I realistically save on my winter energy bill?

Most Australian households implementing 6-8 of these strategies see 15-25% reductions in their winter energy bills. For an average winter bill of $400-500, this translates to $60-125 in savings per quarter, or $180-375 annually.

What's the fastest way to see results?

The quickest wins are adjusting your heating thermostat to 18-20°C, closing doors to unused rooms, and switching to cold water washing. These cost nothing to implement and show immediate results on your next bill.

Which upgrades offer the best return on investment?

In order of payback period: door draught stoppers (immediate), LED bulbs (3-6 months), hot water pipe insulation (6-8 months), smart thermostats (12-18 months), and energy-efficient space heaters (18-24 months for regular users).

Should I switch energy providers?

Absolutely compare! Use the Australian Government's Energy Made Easy website to compare plans in your area. Many households can save $200-400 annually just by switching to a better plan with their existing provider or moving to a competitor.

Do solar panels help with winter energy bills?

Yes, though less dramatically than in summer. Winter solar production drops by 40-60%, but you'll still offset daytime heating and appliance use. If you're considering solar, focus on north-facing roof space and factor in the reduced winter output when calculating payback periods.
