The energy bill lands in the letterbox this October looking heavier than the one before it, even though nothing in the household seems to have changed. The heating has run no longer than usual, the kettle has boiled no more cups of tea, yet the total at the bottom is higher again.
Before that bill is paid, a free government tool can check in under 5 minutes whether a cheaper plan matching actual household usage already exists, and a separate system of rebates may apply depending on which concession card is held. Neither requires switching providers to find out.
What decides the size of an energy bill?
An energy bill comes down to three things: how much electricity and gas the household uses, the price the provider charges for it, and the terms written into the contract, according to MoneySmart. Heating, cooling, kitchen appliances and laundry machines are the largest users of energy in most homes.
That means the same roof, the same family and the same appliances can still produce very different bills from one provider to the next, simply because the contract behind the meter is different.
Where can a bill be compared for free?
Households in New South Wales, Queensland, South Australia, Tasmania and the Australian Capital Territory can run that comparison through the federal government’s Energy Made Easy website. Victorian households use Victorian Energy Compare instead. Both are free, run independently of any energy company, and take under 5 minutes using the usage figures already printed on a current bill.
Western Australia and the Northern Territory sit outside national energy law and run their own comparison channels, through Energy Policy WA and the NT Utilities Commission respectively.
Comparing is not the same as switching. MoneySmart‘s own guidance puts it plainly: “if you’re able to choose your own energy plan, that’s a great starting point.” A household can use the result to ring its existing provider and ask for a better-matching contract rather than moving to a new one.
In New South Wales, south-east Queensland and South Australia, the Australian Competition and Consumer Commission’s Electricity Retail Code requires energy companies to display a standard “comparison price” set by the Australian Energy Regulator, so offers can be read side by side rather than compared on headline discounts alone.
What rebates exist now that federal relief has ended?
The Commonwealth’s National Energy Bill Relief scheme, which had applied a rebate directly to bills nationwide, closed as of 1 July 2026. Households that had relied on that payment now need to check which state-based rebate, if any, has taken its place.
In New South Wales, eligible concession card holders can apply for the Low Income Household Rebate, the NSW Gas Rebate, the Family Energy Rebate, the Medical Energy Rebate and the Life Support Rebate. The Seniors Energy Rebate is available specifically to holders of a Commonwealth Seniors Health Card. Applications and current eligibility sit with the state energy department at energy.nsw.gov.au.
A separate NSW Home Energy Saver program offers a zero-interest loan of up to $15,000 for energy-saving home upgrades, with applications already open. A paired discount of up to $4,000 is listed as “coming soon” on the same page, so the two parts of the program are not yet running on the same timeline.
For households struggling to pay an energy bill at all, the Energy Accounts Payment Assistance scheme exists to help keep essential electricity and gas connected. Anyone living in an apartment block, caravan park or retirement village on a shared embedded network also has specific customer rights, set out separately by the Australian Energy Regulator.
Could bills actually fall over time?
Modelling released by the Grattan Institute in October 2025 found average household energy bills could fall to about $3,000 a year by 2050, down from about $5,800 today, if the electricity sector cuts emissions in line with the national net-zero 2050 target. Grattan’s Energy and Climate Change Program Director, Alison Reeve, said “how we use energy is changing, and the politics of carbon pricing should change too.”
That projection pictures most households by 2050 running on solar panels, a home battery, an electric vehicle and all-electric appliances, a mix that reshapes what a typical bill even measures. It depends on wide uptake of that technology and on emissions policy still to be legislated, so the figure describes a direction rather than a guarantee.
Current rebate amounts, eligibility rules and comparison tools can be confirmed directly through MoneySmart or the relevant state energy department, since figures and closing dates change as programs are updated.
What the bill in the letterbox doesn’t have to be is a mystery. The numbers needed to check it sit on the page already, and the comparison itself costs nothing more than the 5 minutes it takes to run.
