10 Ways to Reduce Your Gas Bill Without Sacrificing Comfort

Rising living costs across Australia, from groceries to mortgages are making it more important than ever for households to manage their energy use effectively. With energy prices under pressure, reducing your gas bill can feel like a daunting task. The good news? You don't need to compromise on comfort to make a difference. Small, practical changes in how you use gas at home can add up to meaningful savings. 


At Australian Gas Networks (AGN), we distribute gas safely and reliably to homes and businesses across Australia. While we don't set your retail gas prices, we are committed to helping households make informed choices about their energy use. 

Here are ten practical, research-backed ways to reduce your gas bill while staying warm, well-fed, and comfortable at home. 
   

1. Compare Retailer Offers  

We don't set your gas prices - your retailer does, so it's important to consider reviewing your energy plan once a year. 

Since 2023, retailers must include a "best offer" message on your bill if you're not already on their most cost-effective plan. Look out for this to avoid overpaying. 

2. Monitor and Understand Your Usage

Knowing how much gas you use is the first step to reducing it. Most energy retailers offer online portals where you can track your gas usage by billing cycle.  

  • Review your "average daily usage" for insights 
  • Compare usage for the same period in previous years 
  • Use this information to identify seasonal trends or unexpected spikes 
Tip: Visit our guide to understanding your gas bill for a detailed breakdown.

3. Set Thermostats Wisely

Heating accounts for a significant portion of household gas use. Setting your thermostat between 18–20°C in living areas is recommended by Energy.gov.au as a comfortable and energy-efficient range. 

  • Each degree above 20°C can increase gas use by up to 10% (Energy.gov
  • Lowering your thermostat even slightly can yield consistent savings 

4. Seal Draughts and Insulate

Heat loss through poorly sealed doors and windows can increase your reliance on heating. 

  • Use weather stripping, door snakes, and heavy curtains 
  • Rugs on bare floors help insulate living areas 
  • Ensure roof and wall insulation is intact and effective 

These passive measures can reduce heat loss and help maintain comfort. 

5. Maintain Appliances for Optimal Efficiency

Appliances that are regularly serviced and well-maintained work more efficiently. 

  • Clean filters in heaters and hot water systems 
  • Check for leaks or blockages 
  • Book regular servicing with a licensed fitter (Find one here)

6. Shorten Shower Times

Heating water is one of the biggest users of household gas. 

Note: Reducing hot water use doesn't mean colder showers, just shorter ones. 

7. Use Zoned Heating Where Possible

Why heat rooms you're not using? 

  • Close doors to unused areas 
  • Use zoned settings on ducted systems 
  • Portable gas heaters should be used safely and only in occupied spaces 

Strategic zoning can help reduce overall consumption without discomfort. 

8. Upgrade to More Efficient Appliances

If your gas appliances are more than 10–15 years old, they could be using more energy than necessary. 

  • Check the star rating system for energy efficiency 
  • Newer models often have lower running costs 
  • Compare long-term savings with Energy Made Easy 
Note: These tips are intended for households already using gas. However, the effectiveness of upgrading appliances may vary depending on factors such as: 
  • The size and layout of your home 
  • The quality of your insulation 
  • The efficiency and age of your existing appliances

Rebate Opportunities

Households on AGN networks in South Australia, Queensland, and New South Wales may be eligible for rebates when upgrading to approved gas appliances. These incentives can assist with offsetting initial purchase and installation costs. View current rebates available.

Please note: Rebates are not currently offered in Victoria. 

Evaluating these elements will help you make the most informed decisions about potential upgrades. 

9. Use Timers and Programmable Thermostats

Smart usage of your heating system can reduce waste.  

  • Set heating to switch off 15 minutes before bed or leaving home 
  • Program heating to warm rooms just before you wake or arrive home 
  • Avoid heating overnight unless medically necessary 

These simple routines save energy with no loss of comfort.

10. Cook Smart with Gas

Efficient cooking habits can help reduce gas use in the kitchen: 

  • Always use lids on pots and match burner size to cookware 
  • Turn off the burner slightly early and use residual heat 
  • Try passive cooking: bring food to a boil, cover, then switch off heat and let it finish cooking (e.g. pasta) 

Small changes in cooking habits can lead to noticeable savings over time. 

Conclusion

Managing your gas bill doesn’t require sacrifice, just smarter usage. By: 

  • Monitoring your consumption 
  • Optimising your heating habits 
  • Maintaining appliances and making everyday adjustments, you can stay comfortable while keeping your energy costs in check. 

Take action today: check your latest gas bill, evaluate your thermostat settings, and explore your retailer's online portal for insights. These small steps can lead to real, lasting savings.
