Every washing machine claims to be energy efficient.
The truth?
Some are great at saving power and water, while others just say they do.
If you’re tired of guessing which models actually deliver savings, this guide cuts through the noise.
We’ve spent more than 40 years helping Australians choose washing machines that balance performance, efficiency, and value.
In just a few minutes, you’ll know how to spot genuine energy-saving models, read the labels with confidence, and choose a washing machine that fits your home, your habits, and your budget.
What Makes a Washing Machine Energy Efficient?
An energy-efficient washing machine cleans clothes using less power and water without reducing performance.
The key is how it’s designed, not just what the label says.
Most efficiency gains come from technology that adjusts how the machine runs.
Features like inverter motors, eco modes, and load sensing help washers use only the energy and water needed for each cycle.
The result is lower running costs and less strain on the environment.
Front-load washers are often more efficient than top-load washing machines because they use gravity instead of a central agitator.
They spin faster, remove more water, and reduce drying time, all of which save electricity over the long term.
Even small changes can make a big difference.
A 5-star washing machine can use up to 56% less energy* than a 3-star model.
Over the life of the machine, that can mean hundreds of dollars saved on household bills.
The takeaway? True efficiency isn’t about fancy features or marketing claims.
It’s about finding a machine that delivers great cleaning while keeping power and water use to a minimum.

Understanding Energy and Water Rating Labels
When comparing energy-efficient washing machines, the first thing to check is the label.
These star ratings show how much electricity and water a model uses each year.
The more stars, the more efficient the machine.
Both labels are part of Australian government programs that make it easier to compare products before you buy.
Here’s how they work.
Energy Rating Label
The Energy Rating Label is managed by the Australian Government’s Energy Rating program.
It tells you how much power the machine uses each year, based on standard test conditions.
It ranges from 1 to 10 stars, but most washers fall between 1 and 6.
The higher the star rating, the less energy used.
The stars make it easy to see which models use less energy for the same washing performance.
Energy Star Rating Comparison
| Energy Star Rating | Approx. Energy Use per Year | Estimated Annual Running Cost* | Performance Overview |
|---|---|---|---|
| ★★☆☆☆☆ (2 Star) | ~600–700 kWh | ~$180-$245 | Standard performance. Moderate savings. |
| ★★★☆☆☆ (3 Star) | ~400–500 kWh | ~$120-$175 | Good efficiency for smaller households |
| ★★★★☆☆ (4 Star) | ~250–325 kWh | ~$75-$115 | Strong energy savings. Great all-rounder. |
| ★★★★★☆ (5 Star) | ~180–220 kWh | ~$54-$77 | High efficiency. Ideal for frequent use. |
| ★★★★★★ (6 Star) | ~100–150 kWh | ~$30-$50 | Premium performance. Among the best in market. |
Energy use and yearly running costs are estimates only. Figures are based on an average Australian electricity price of 30–35¢ per kWh and typical usage patterns for an 8kg washing machine. Actual costs will vary depending on your household’s habits, machine settings, water temperature, and local electricity rates. For detailed calculations or other washing machine sizes, visit the official Energy Rating Calculator at https://calculator.energyrating.gov.au/Washer.asp
A 4-star washing machine can cost $75–$115 per year, while a 3-star model sits around $120–$175 per year.
That difference adds up to $45–$60 in savings every year, or roughly $450–$600 over a 10-year lifespan.
The gap is even larger if you’re replacing an older 2-star washer, where long-term savings can exceed $1,000.
WELS Rating (Water Efficiency)
You’ll also see the blue WELS label, which stands for Water Efficiency Labelling and Standards.
It measures how much water a washer uses per cycle.
It runs from 1 to 6 stars, and again, more stars mean better efficiency.
WELS (Water Efficiency) Rating Comparison
| WELS Star Rating | Approx. Water Use per Cycle | Performance Overview* |
|---|---|---|
| ★★☆☆☆☆ (2 Star) | 120–150 L | Moderate efficiency. |
| ★★★☆☆☆ (3 Star) | 90–118 L | Average efficiency. Standard household use. |
| ★★★★☆☆ (4 Star) | 59–82 L | Good savings. Common in newer washers. |
| ★★★★★☆ (5 Star) | 54–58 L | Excellent efficiency. |
| ★★★★★★ (6 Star) | 40–50 L | Exceptional efficiency. Advanced design. |
Water-use figures are based on typical ranges listed in the Australian WELS public register. Actual usage can vary depending on load size, wash programs, soil level, and machine design. For verified product-specific data or to compare other washing machine models, visit the WELS database at https://wels-public-register.environment.gov.au/
If you live in an area with water restrictions or higher utility rates, aim for a washing machine with both a 4-star or higher energy rating and a 4-star or higher WELS rating.
This combination offers the best balance of power and water efficiency.
Quick Tip: Check both labels before you buy. The most energy-efficient washing machines score well on both energy and water ratings, giving you cleaner clothes, lower bills, and a smaller environmental footprint.
Is a Front-Load vs Top-Load Washing Machine More Energy Efficient?
One of the biggest choices our customers face when buying a washing machine is whether to go with a front loader or a top loader.
Both clean clothes well, but they work differently, which affects how much energy and water they use.
Front-Load Washing Machines
Front-loaders use gravity to tumble clothes through a smaller amount of water.
They spin faster, which removes more moisture before drying, and this helps reduce total energy use.
Most models also include high-efficiency motors, eco wash settings, and temperature controls that use less power.
These design differences mean front-loaders are usually more efficient overall.
Top Load Washing Machines
Top loaders fill most of the drum with water and rely on an agitator or impeller to clean clothes.
They’re often cheaper to buy upfront and have shorter wash cycles, but they typically use more power and water per load.
Modern top loaders have improved in recent years, especially those with inverter motors and smart sensors, but they still lag slightly behind front loaders for efficiency.

Efficiency Comparison
| Feature | Front-Load Washing Machine | Top-Load Washing Machine |
|---|---|---|
| Water Use | Lower (60–80 L per cycle) | Higher (90–140 L per cycle) |
| Energy Use | Lower overall | Moderate to high |
| Cycle Time | Longer (60–120 mins) | Shorter (30–60 mins) |
| Spin Speed | Faster (up to 1400 rpm) | Slower (up to 1000 rpm) |
| Ease of Use | Requires bending to load/unload | Easier to access, especially for mobility needs |
| Purchase Price | Usually higher upfront | Often lower upfront |
| Running Cost | Lower over time | Higher over time |
| Best For | Energy-conscious households | Users wanting quick, simple cycles |
Key Takeaway: If your goal is to cut energy and water bills, a front-load washing machine is usually the better long-term investment. If you prefer quick cycles and a lower upfront cost, a top loader may still suit your needs, especially if you choose one with at least a 4-star energy rating.
Features That Improve Washing Machine Efficiency
The best energy-efficient washing machines combine smart design with features that reduce power and water use every cycle. Here’s what to look for:
- Inverter motor: Adjusts its speed to match the load, using only the energy needed. It runs quietly, lasts longer, and helps reduce running costs. (Learn more about the quietest washing machines on the market)
- Load sensing: Detects how much laundry is in the drum and adjusts water and cycle time automatically. This avoids wasting energy on small loads.
- Eco wash settings: Use lower temperatures and longer cycles to save energy while still achieving a deep clean. Great for everyday washing.
- High spin speeds: Remove more moisture from clothes, cutting down on dryer time and power use.
- Cold wash options: Clean effectively with cold water, which can halve energy use compared to warm cycles.
- Auto detergent dispensing: Measures and releases the right amount of detergent for each load, preventing waste and improving wash performance.
Quick tip: A washing machine with these features can outperform another model with the same star rating but fewer efficiency tools. The right combination helps you save more energy, water, and money over time.
How Much Can an Energy-Efficient Washing Machine Really Save You?
Switching to an energy-efficient washing machine can make a noticeable difference to your household bills.
The savings depend on your machine’s star rating, the frequency of washing, and your local electricity and water rates.
- A 3-star washing machine might cost around $140 a year to run.
- A 5-star model could cost closer to $100 a year.
- That’s a saving of about $40 per year, or roughly $400 over a decade— and even more if you’re replacing an older or lower-rated washer.
Add water savings on top of that. A 4-star WELS model can use 40–60 litres less water per wash compared to a 2-star washer.
For families that run multiple loads each week, this adds up to thousands of litres saved every year.
The result isn’t just lower bills, it also means less energy use, fewer carbon emissions, and longer-lasting appliances due to smarter operation.
Quick tip: When comparing models, look at both the energy and water labels. A machine that performs well in both areas offers the best long-term return on investment.
How to Choose the Best Energy-Efficient Washing Machine for Your Home
The right washing machine for your home depends on how you live, not just the number of stars on the label. Use these steps to narrow down your options and find a model that delivers real value.
1. Pick the right capacity
Choose a drum size that matches your household.
- 6–7kg suits singles or couples.
- 8–9kg works for small families.
- 10kg or more is ideal for larger households.
A machine that’s too big wastes water and power. One that’s too small will need more cycles.
2. Compare energy and water ratings
Look for at least 4 stars for both energy and WELS ratings.
The higher the stars, the lower your running costs over time.
3. Check efficiency features
Prioritise features such as inverter motors, load sensing, eco modes, and cold wash options.
These help save energy every cycle without affecting cleaning results.
4. Balance cost and performance
An energy-efficient washing machine may cost more upfront, but it usually pays for itself through lower power and water bills.
5. Match features to your lifestyle
If you wash frequently, focus on speed, spin power, and build quality.
For smaller households, compact models with eco settings offer great efficiency in less space.
