Gas to Electric Calculator: Should You Ditch Gas in Australia 2026?
Gas supply charges cost $350 to $400 per year just to stay connected, before you burn a single cubic metre of gas. Replacing your gas cooktop, hot water, and heating with electric alternatives eliminates that charge and typically reduces your total energy costs as well.
The ACT pays up to $5,000 for households that complete full gas disconnection. Victoria's VEU program offers $1,000 to $8,000 in discounts on gas-to-electric appliance upgrades depending on the combination. Federal STCs reduce heat pump hot water costs by around $975 nationally.
The question is not whether to go all-electric. For most gas households, the economics now clearly favour it. The question is which appliance to replace first and how to sequence the transition to maximise the return. Enter your details below to see your optimal gas-switching plan.
How the Gas Switch Calculator Works
Appliance-by-Appliance Modelling
The calculator treats each gas appliance separately. Hot water, cooktop, space heating, and any other gas appliances are each evaluated for replacement cost, running cost saving, and available rebates. You can see which replacement delivers the best return and which unlocks the gas supply charge saving.
The Gas Supply Charge Unlock
You only save the $350 to $400 per year gas supply charge once you replace every gas appliance in the house. The model tracks which appliances remain on gas and adds the supply charge saving to the final appliance replacement that gets you to zero gas usage. This makes sequencing important.
State-Specific Rebates
Gas-switching rebates vary significantly by state. VIC and ACT have the most generous programs. The calculator applies the correct rebate stack for your postcode, including both state incentives and the federal STC rebate for heat pump hot water, to give you an accurate out-of-pocket cost for each appliance switch.
Gas to Electric FAQ
How much does it cost to disconnect gas?
The gas network disconnection fee varies by distributor but typically runs $100 to $300. The real cost is replacing your gas appliances with electric alternatives. A heat pump hot water system runs $1,200 to $2,500 out of pocket after rebates. An induction cooktop is $500 to $2,000. Reverse cycle heating runs $1,500 to $4,000 per unit depending on size. The ACT pays up to $5,000 directly to offset these costs for eligible households switching off gas entirely.
How much will I save by going all-electric?
The gas supply charge alone is $350 to $400 per year just for the connection, regardless of how much gas you use. Add the difference between gas and electric running costs for each appliance, and total annual savings from full electrification typically run $600 to $1,500 per year depending on your gas usage, your electricity rate, and whether you have solar. The savings grow over time as gas prices continue to rise faster than electricity prices.
Which gas appliance should I replace first?
Hot water first, in most cases. A gas hot water system is the single largest gas energy user in most homes, and replacing it with a heat pump delivers the biggest running cost reduction. If you can then replace your cooktop with induction and your heating with reverse cycle, you can disconnect gas entirely. The calculator models each appliance separately and shows you the optimal replacement sequence based on your home's specific gas appliance mix.
Is induction cooking cheaper than gas?
Yes, in nearly all cases. A gas cooktop uses more energy than it delivers as heat because of combustion losses. An induction cooktop transfers energy directly to the cookware at 85 to 90% efficiency versus around 40% for gas burners. At current gas and electricity prices, induction is cheaper to run for most households. With solar, daytime cooking on induction can be nearly free. Modern induction cooktops also heat faster and are easier to clean.
What rebates are available for switching from gas?
VIC has the most comprehensive gas-switching support through the Victorian Energy Upgrades (VEU) program, offering $1,000 to $8,000 in appliance discounts depending on the combination of upgrades. ACT pays up to $5,000 for full gas disconnection under the Gas Substitution Roadmap and offers interest-free loans for electric appliances. NSW has the Energy Savings Scheme covering heat pump hot water. Federal STCs apply to heat pump hot water nationally. SA and QLD have smaller or more targeted programs. Our calculator applies all relevant rebates for your postcode.
