Winter in Australia can be beautiful, but there is one thing many households don’t look forward to: the electricity bill.
As temperatures drop, heating, hot water, clothes dryers and other appliances can quickly increase household electricity consumption.
The good news is that you don’t necessarily need to sit in a freezing house to save money.
There are several simple changes you can make this winter that can reduce unnecessary electricity use while keeping your home comfortable.
In this guide, we’ll look at 10 practical ways to save money on your electricity bill in Australia during winter 2026, including heating, hot water, laundry, electricity plans and government assistance.
Quick Take
- Heating can become a major source of electricity use during winter.
- Small changes to heating habits can make a noticeable difference over time.
- Comparing electricity plans can be just as important as reducing your electricity usage.
- Australian and state governments offer various rebates, discounts and energy-saving programs.
- You don’t need to make your home uncomfortable to reduce your electricity bill.
Why Does Your Electricity Bill Go Up in Winter?
Winter electricity bills can be higher simply because households tend to use more energy.
Heating is an obvious example, but it isn’t the only one.
During colder months, you may also:
- Run your heater for longer
- Take longer or hotter showers
- Use your clothes dryer more frequently
- Spend more time indoors
- Use more lighting
- Cook more meals at home
- Keep appliances running for longer
The result is that even if your electricity price hasn’t changed significantly, your total electricity consumption can increase.
It’s also important to understand the difference between electricity prices and your actual bill.
The Australian Energy Regulator’s 2026–27 Default Market Offer applies from 1 July 2026. In NSW, the regulated reference prices for residential customers decreased compared with the previous year, but the AER makes clear that the DMO is not a cap on an individual customer’s bill. What you actually pay depends on your electricity usage and the rates charged by your retailer.
That means reducing unnecessary energy use can still make a difference.
1. Don’t Overheat Your Home
One of the easiest ways to waste electricity in winter is simply running your heater harder than necessary.
If your home feels comfortable at a moderate temperature, there is usually little reason to turn the heating up dramatically.
Instead of trying to make the room feel like summer, aim for a comfortable indoor temperature and wear warm clothing when necessary.
A jumper, thick socks and warm clothing can allow you to reduce your reliance on heating without sacrificing comfort.
A simple rule:
Heat the person, not the entire house.
If you’re spending the evening in one room, you may not need to heat every room in the house.
2. Use Your Heater Efficiently
If you use a reverse-cycle air conditioner for heating, avoid constantly turning it on and off throughout the day.
Instead, use it strategically and keep doors and windows closed while you’re heating a room.
NSW Energy notes that efficient reverse-cycle air conditioners can provide both heating and cooling and can be an energy-efficient option for households.
If you’re considering replacing an old air conditioner, it’s also worth checking whether you qualify for a NSW Government incentive. The NSW Energy Savings Scheme currently provides incentives for eligible households upgrading to more energy-efficient air conditioning.
Tip: Clean your air conditioner’s filters regularly. A dirty filter can restrict airflow and make the system work harder.
3. Stop Cold Air From Sneaking Into Your Home
You can have an efficient heater and still waste energy if warm air constantly escapes.
Check the areas around:
- Doors
- Windows
- Sliding doors
- Cracks around frames
- Gaps under doors
Simple measures such as door seals, window coverings and curtains can help reduce drafts.
You don’t necessarily need to spend thousands of dollars renovating your home.
Start with the obvious gaps.
Try this tonight:
Stand near your front door or a window on a cold evening.
If you can feel cold air coming through, you’ve probably found somewhere that needs attention.
4. Use Curtains to Keep Warm Air Inside
Curtains aren’t just for privacy.
They can also help create a barrier between your living space and cold windows.
During the evening, close your curtains to help reduce heat loss through windows.
During sunny winter days, you can also open curtains on sun-facing windows and take advantage of natural sunlight.
It’s a simple habit, but unlike running a heater, sunlight doesn’t send you an electricity bill.
5. Be Careful With Your Clothes Dryer
The clothes dryer can become a surprisingly expensive appliance during winter.
When it’s cold or raining, it’s tempting to put everything straight into the dryer.
But if you have access to a clothesline, balcony or indoor drying area, consider air-drying clothes whenever practical.
You don’t have to stop using your dryer completely.
Instead:
Use the dryer when you need it, rather than automatically using it for every load.
You can also:
- Use the highest practical spin cycle in your washing machine
- Avoid overloading the dryer
- Clean the lint filter regularly
- Dry multiple loads together when appropriate
Reducing dryer usage can also reduce the amount of time your dryer runs.
6. Don’t Waste Hot Water
Hot water can be another important part of household energy use.
Long, very hot showers may feel fantastic during winter, but they can increase both water and energy consumption.
Try reducing shower time slightly.
For example:
20-minute shower → 10-minute shower
doesn’t sound dramatic, but repeating that change regularly can reduce the amount of hot water your household needs.
If your hot water system is old, it’s also worth investigating whether upgrading could make financial sense.
The NSW Government currently offers incentives for eligible households upgrading to more energy-efficient hot water systems.
7. Turn Off Appliances You Aren’t Using
Some appliances continue consuming electricity when they’re left in standby mode.
Think about:
- TVs
- Gaming consoles
- Computers
- Monitors
- Speakers
- Chargers
- Kitchen appliances
You don’t need to walk around the house unplugging every device every night.
Instead, focus on appliances that aren’t needed for long periods.
NSW Energy specifically recommends switching off appliances when they aren’t being used, including devices such as TVs, gaming consoles and chargers.
A power board with an on/off switch can make this easier.
For example:
TV + console + speakers → one power board → one switch
Turn the switch off when you’re finished.
8. Check Your Electricity Plan
This is one of the most important steps — and one that many people forget.
You can spend weeks trying to reduce your electricity usage, but if you’re paying more than necessary for your electricity plan, you may be leaving money on the table.
The Australian Government provides Energy Made Easy, a free comparison service for households and small businesses in NSW and several other Australian states and territories. It allows consumers to compare electricity and gas plans from different retailers.
Before switching plans, have a recent electricity bill available.
Look at:
- Usage
- Supply charges
- Usage rates
- Discounts
- Contract conditions
- Any exit fees
- Solar feed-in rates if applicable
Don’t choose a plan based only on the biggest advertised discount.
Look at the estimated total cost for your household.

9. Take Advantage of Energy Rebates and Government Support
Before paying full price for an energy upgrade, check whether you qualify for government assistance.
NSW currently has several programs designed to help households reduce energy costs or improve energy efficiency.
Depending on your circumstances, support may be available for things such as:
- Energy bills
- Air conditioning upgrades
- Hot water systems
- Home energy improvements
- Other energy-efficient upgrades
The NSW Government maintains a current list of rebates, grants and incentives for households.
There are also new energy-saving initiatives being introduced during 2026. For example, the NSW Government announced targeted discounts of up to $4,000 for eligible households later in 2026, subject to eligibility requirements.
Because eligibility and program conditions can change, always check the official government website before making a purchase based on a rebate.

10. If You Have Solar, Think About When You Use Electricity
Solar households have another opportunity to reduce electricity costs.
Instead of using large appliances whenever you feel like it, consider using some of them during periods when your solar system is producing electricity.
Depending on your electricity plan and household setup, shifting electricity consumption to periods of lower-cost or solar-generated electricity may reduce your bill.
There is also a new Solar Sharer Offer for eligible households in NSW and some other states, providing three hours of free electricity in the middle of the day. In NSW and South East Queensland, the current free-power window is 11am to 2pm. Eligibility and retailer availability apply.
If you have solar, check your retailer’s plan carefully before changing your usage habits.
A Simple Winter Electricity-Saving Checklist
You don’t need to change everything at once.
Start with these 10 habits:
Heating
☐ Don’t overheat empty rooms
☐ Keep doors and windows closed while heating
☐ Clean your heater or air-conditioner filters
☐ Seal obvious drafts
Appliances
☐ Reduce unnecessary dryer use
☐ Switch off appliances when you’re finished
☐ Avoid leaving entertainment devices on standby unnecessarily
Hot Water
☐ Take shorter showers
☐ Avoid unnecessarily hot showers
☐ Investigate efficient hot water options if your system is old
Electricity Plan
☐ Check your latest electricity bill
☐ Compare available plans
☐ Check government rebates and assistance
How Much Can You Actually Save?
This is where you should be careful with online electricity-saving advice.
There is no universal answer.
A household with a small apartment, efficient heating and low electricity consumption will have a very different bill from a large house using electric heating throughout the day.
Your potential savings depend on:
- Home size
- Number of people
- Heating system
- Insulation
- Hot water system
- Electricity retailer
- Electricity tariff
- Appliance efficiency
- Daily electricity consumption
- Solar panels and battery storage
So be skeptical of articles promising:
“Save $1,000 on your electricity bill this winter!”
There is no single number that applies to every Australian household.
A better approach is to identify where your household is actually using electricity and focus on the biggest opportunities first.
The Bottom Line
Saving money on your Australian electricity bill this winter doesn’t have to mean sitting under a blanket in a freezing house.
The biggest improvements often come from making small changes consistently.
Use your heating more efficiently. Reduce unnecessary dryer use. Keep warm air inside your home. Take shorter hot showers. Switch off appliances you’re not using.
And don’t forget one of the easiest things to overlook:
Check your electricity plan.
Government comparison tools such as Energy Made Easy can help eligible households compare available offers, while state and federal programs may provide additional support for eligible households.
The goal isn’t to stop using electricity.
It’s to stop paying for electricity you don’t actually need.
