How to Reduce Your Gas Bills in 2025

If your gas bills have been creeping up lately, you’re not alone. With energy prices fluctuating and colder months hitting harder, many households are looking for ways to cut back on their gas usage without sacrificing comfort.

Fortunately, there are plenty of simple, practical steps you can take to reduce your gas bills in 2025 – starting today. From upgrading to energy-efficient appliances to sealing up drafts around the house, even small changes can lead to big savings over time.

Whether you’re heating your home, cooking, or running your hot water system, smarter choices make all the difference. In this guide, we’ll walk you through easy and effective ways to lower your gas usage, keep your home cosy, and put more money back in your pocket.

Upgrade to Energy-Efficient Gas Appliances

One of the smartest ways to reduce your gas bills in 2025 is by upgrading to energy-efficient gas appliances.

Older heaters, ovens, and hot water systems often use more gas than necessary, which means you’re paying more for less efficiency. Newer models are designed to do the same job – or better – while using less energy.

When shopping for appliances, keep an eye out for the energy star rating. The more stars, the more efficient the appliance. It’s also worth checking if your local government or energy provider is offering rebates or incentives for upgrading to energy-efficient options.

Yes, the upfront cost might seem high, but the savings on your gas bills can quickly add up. Plus, these appliances are often more reliable and environmentally friendly. Think of it as an investment – not just in your home, but in lower running costs and a more sustainable future.

Schedule Regular Maintenance for Gas Appliances

Keeping your gas appliances in top shape is one of the easiest ways to reduce your gas bills.

Over time, heaters and hot water systems can lose efficiency due to wear, dust build-up, or minor faults. Regular maintenance ensures everything runs smoothly – and uses less gas.

Here’s why scheduling a yearly service is a smart move:

• Improved efficiency – A clean, well-tuned system uses less gas to do the same job.
• Longer lifespan – Regular check-ups help spot problems early, avoiding costly breakdowns.
• Better safety – Technicians check for gas leaks or carbon monoxide risks, keeping your home safe.
• Consistent comfort – You’ll enjoy reliable heating and hot water, especially in winter.

Book a licensed technician to service your appliances at least once a year. A small maintenance cost now can lead to big savings on your gas bills down the track.

Improve Insulation in Your Home

If your home isn’t properly insulated, you could be losing a lot of heat – and money – without even realising it. Poor insulation allows warm air to escape during winter, forcing your gas heater to work overtime just to keep things comfortable. That extra effort means higher gas bills.

Improving insulation is one of the most effective ways to reduce your gas usage. Start by checking your roof and ceiling – these are the biggest culprits when it comes to heat loss. Next, look at your walls, floors and even your windows. Double glazing and thermal curtains can make a big difference too.

While some insulation upgrades can be a DIY job, you might want to get a professional to assess your home for the best results. Once your home is properly sealed and insulated, you’ll find it stays warmer for longer – with less reliance on gas heating. That’s a win for comfort and your wallet.

Use a Programmable or Smart Thermostat

If you’re still relying on manual temperature settings, it’s time to upgrade to a programmable or smart thermostat. These clever devices can help you take control of your gas usage and cut down on waste – without sacrificing comfort.

Here’s how they make a difference:

• Set and forget – Program your heating schedule to match your routine. No more heating an empty house.
• Remote control – Smart thermostats let you adjust the temperature from your phone, even when you’re not home.
• Energy tracking – Many models offer insights into your usage, so you can make smarter choices.
• Zoned heating – Some systems let you heat specific areas rather than the whole house, saving even more gas.

By only using gas when and where you really need it, a smart thermostat can help reduce your bills and make your home more efficient.

Seal Drafts and Close Off Unused Rooms

Want a simple trick to lower your gas bill? Start by sealing up drafts and closing off any rooms you’re not using. It might sound small, but it makes a big difference.

Gaps around doors, windows, and even floorboards let warm air escape and cold air sneak in. That means your gas heater has to work harder – and use more gas – to keep the house warm.

Grab some weather stripping, door snakes, or caulking to seal up those sneaky leaks. You don’t need to be a DIY expert – most fixes are quick and affordable.

Also, don’t waste heat on rooms you’re not using. Shut the door to spare bedrooms, studies, or other areas and focus on keeping the spaces you live in nice and toasty. This way, you’ll use less gas, stay just as comfortable, and notice a drop in your energy bills without even trying too hard.

Shorten Hot Showers and Use Cold Wash Cycles

Want a quick way to lower your gas bills without spending a cent? Start by rethinking how you use hot water. It might not seem like much, but daily habits like long showers and hot laundry cycles can add up fast on your gas bill.

Here’s how to cut back:

• Take shorter showers – Reducing your shower time by just a few minutes can save litres of hot water (and gas) each day.
• Install a water-saving showerhead – These reduce flow without compromising on comfort, using less hot water overall.
• Wash clothes in cold water – Most modern detergents work just as well in cold water, and you’ll skip the need to heat water altogether.
• Only run full loads – Whether it’s the washing machine or dishwasher, wait until it’s full to get the most out of each cycle.

Small changes = big savings over time.

Consider Solar Hot Water Boosted by Gas

Looking for a long-term way to cut down your gas bills? A solar hot water system with a gas booster might be the perfect solution.

These systems use the sun’s energy to heat your water, and the gas booster kicks in only when the sun can’t do the job – like on cloudy days or during winter. That means you’re using way less gas overall.

Yes, there’s an upfront cost to install a solar system, but the long-term savings can be impressive. Plus, you’ll reduce your household’s carbon footprint, which is a nice bonus for the environment.

Many homes across Australia are already making the switch, and with rising energy prices, it’s a smart move for 2025. There may even be government rebates or incentives available to help with the cost. If you use a lot of hot water, this upgrade could slash your gas bills for years to come.

Monitor Your Gas Usage

If you want to reduce your gas bills, the first step is understanding how much you’re actually using. By keeping an eye on your gas consumption, you can spot patterns, avoid waste and make smarter decisions around the home.

Here’s how to get started:

• Check your gas meter regularly – A quick weekly check can show you if your usage is spiking unexpectedly.
• Use your energy provider’s app or online portal – Many companies offer real-time usage tracking, charts, and comparisons.
• Set usage goals – Aim to reduce your gas use each month and track your progress.
• Look for unusual activity – A sudden increase could mean there’s a possible gas leak or an appliance isn’t working efficiently.
• Review past bills – Comparing your current and previous usage can help you pinpoint what’s working.

Awareness is key. When you know where your gas is going, it’s easier to cut costs.

Keep Money in Your Pocket

Reducing your gas bills in 2025 doesn’t have to mean sacrificing comfort – it’s all about making smarter choices.

Whether you’re sealing up drafts, shortening your showers, or upgrading to energy-efficient appliances, every small change can add up to big savings. Don’t forget the power of regular maintenance and using tools like smart thermostats to stay in control of your usage.

If you’re ready to go a step further, consider investing in solar hot water boosted by gas for long-term benefits.

The more you understand and manage your gas consumption, the more money you’ll keep in your pocket. Start with one or two tips today and build from there. Before you know it, you’ll have a warmer, more energy-efficient home – and a much lower gas bill to go with it.
