With energy prices set to surge again from July 1—some Aussies could see their bills jump by nearly 10%—it’s no wonder so many of us are looking for ways to keep more money in our pockets. But don’t worry, you don’t need to be a tradie or a home renovation guru to make a real difference to your power bill. We’ve gathered the best advice from Fouad Reaiche, managing director at ETH Construction Group, and added a few extra tips and insights to help you stay cool (or warm!) without breaking the bank.


1. Double Glazing: The Unsung Hero of Home Comfort

If you’ve ever stood next to a window in the middle of winter and felt a chill, you already know how much heat can escape through glass. Double glazing is a game-changer. By adding a second pane of glass with a gap in between, you create a powerful barrier that slows down heat transfer. In winter, it keeps the warmth in; in summer, it keeps the heat out.


While the upfront cost can range from $300 to $1,500 per square metre, the long-term savings are impressive. According to Bradnam’s Windows and Doors, switching to double-glazed windows can cut your energy bills by up to 20%. And if you’re feeling extra fancy, triple glazing is even more effective—though it comes with a higher price tag.


Not ready for a full window overhaul? Thermal-blocking blinds and heavy curtains can also make a noticeable difference, especially if you live in an older home with single-pane windows.

2. Draft Blockers: Small Investment, Big Impact

It’s amazing how much cold or hot air can sneak in under doors and around windows. Draft blockers are a simple, affordable fix that can make your home more comfortable year-round. Pop them on your entry doors, and you’ll immediately notice fewer chills in winter and less hot air creeping in during summer.

You can buy ready-made draft stoppers or get creative and make your own with some fabric and a bit of stuffing. Either way, you’ll be plugging up one of the biggest sources of energy loss in the home.

3. Upgrade to Energy-Efficient Air Conditioning

Did you know that heating and cooling account for more than half of the average Aussie household’s energy use? And air conditioning alone chews through about 15% of the nation’s total power. If your air con is more than a decade old, it’s probably guzzling electricity.


Modern units are much more efficient, with features like inverter technology and smart thermostats that help you stay comfortable without running up the bill. Look for models with a high energy star rating, and consider split systems for targeted cooling and heating.

4. Insulation: The Foundation of Energy Savings

Insulation isn’t just for new builds—it’s one of the best investments you can make in any home. Proper roof and ceiling insulation can slash your heating and cooling energy use by up to 45%, according to the Department of the Environment, Water, Heritage and the Arts.


If you’re building or renovating, make sure you choose insulation suited to your climate zone. For existing homes, it’s worth checking if your insulation is up to scratch—over time, it can settle or become less effective. Wall and underfloor insulation are also worth considering, especially in older homes.

5. Don’t Be Loyal—Shop Around for a Better Deal

It’s easy to stick with the same energy provider year after year, but loyalty rarely pays off in the power game. Providers often reserve their best deals for new customers, so it pays to compare offers regularly. Switching is easier than you might think, and you could save hundreds of dollars a year just by making a few phone calls or using an online comparison tool.


Bonus Tips for Savvy Savers

• Use Appliances Wisely: Run your dishwasher and washing machine with full loads, and use cold water where possible.
• Switch to LED Bulbs: They use a fraction of the energy of old incandescent bulbs and last much longer.
• Seal Gaps and Cracks: Check around windows, doors, and even power points for sneaky leaks.
• Monitor Your Usage: Many energy providers offer apps or online tools to track your usage in real time—knowledge is power!

The Bottom Line


With energy prices on the rise, a few smart changes can make a big difference to your comfort and your wallet. Whether you’re ready for a big upgrade like double glazing or just want to start small with draft stoppers, every step counts.
