You don't need solar panels, a battery, or a home renovation to cut your electricity bill. The biggest savings come from things that cost nothing — switching off a bad plan, claiming rebates nobody told you about, and making one phone call to your retailer. Most Australian households are overpaying by $200\u2013$600 per year simply because they've never checked.
This list is ordered from highest impact to easiest action. The first three items alone can save most households $300\u2013$500 per year. None of them require buying anything, installing anything, or changing the way you live. They just require knowing what to look for — which is exactly what your electricity retailer is hoping you never do.
A standing offer is the default, most expensive electricity plan — the one you end up on if you've never compared or switched. It's like paying full price for a hotel room when everyone else booked online for half the rate. One phone call to your retailer asking to switch to a market offer can save $200–$500 per year. You don't need to change retailers — just ask them for their best current market offer. If you're not sure whether you're on a standing offer, upload your bill to BillDecoder and we'll tell you.
Most Australian states have electricity rebates that go unclaimed because nobody tells you about them. In NSW, the Low Income Household Rebate is worth $285/year for pensioners and healthcare card holders. Victoria offers a 17.5% concession off usage and supply charges. Queensland provides $386/year for pensioners, veterans, and seniors. These rebates don't appear automatically — you have to apply. Check your state government's energy concessions page, or upload your bill to BillDecoder and we'll identify every rebate you may be eligible for.
Retailers almost always have a retention offer they don't advertise. When you call and say you're thinking of switching, they'll check what they can offer. Here's a script that works: "I'm comparing plans and thinking of switching. What's the best rate you can offer me right now?" Be specific — ask for the per-kWh rate and daily supply charge, not just a percentage discount. Percentage discounts can be misleading because they often only apply to usage charges, not the whole bill. A 20% discount on usage might only save you 10% on the total.
If you're on a time-of-use pricing plan, electricity costs significantly more during peak hours (typically 2pm–8pm on weekdays) and much less during off-peak hours (typically after 10pm and on weekends). Running your dishwasher, washing machine, and dryer after 10pm instead of during peak hours can save $150–$300 per year depending on your rates. You don't need to change your lifestyle dramatically — just shift the timing of appliances that don't need to run at a specific time.
Billing errors are more common than most people think. Estimated meter reads (where the retailer guesses your usage instead of reading the meter) can be significantly wrong. You might also be on the wrong tariff, be missing a discount that was promised, or have incorrect meter data. Look for the word "estimated" on your bill — if you see it, your bill might not reflect your actual usage. BillDecoder checks for common billing anomalies as part of every analysis.
Energy Made Easy is the Australian Government's free electricity comparison tool. It shows you every available plan in your area with no commissions or affiliate fees — the results are genuinely independent. You'll need your meter number (NMI) from your bill and your most recent usage data. BillDecoder extracts this information for you automatically, making it easier to plug into Energy Made Easy for a comparison.
If you have an electric hot water system, it may be on a controlled load tariff — a separate meter circuit that runs on cheaper off-peak rates. But controlled load only saves money if it's actually set up correctly. If your hot water timer has been changed, or if your hot water system was replaced and the electrician didn't reconnect the controlled load circuit, you could be heating water on expensive peak rates without realising it. Check your bill for a controlled load line item — if it's not there but you have electric hot water, it's worth investigating.
Appliances left on standby — TVs, game consoles, phone chargers, microwaves, computer monitors — all draw small amounts of power even when they appear to be off. Individually it's tiny, but across a whole household it adds up to $100–$150 per year. The simplest fix is a power board with an on/off switch for your entertainment centre and home office. One click turns off everything at the wall. Smart power boards can do this automatically when devices go to sleep.
Every degree you set your air conditioner below 24°C adds roughly 10% to your cooling costs. Setting it to 21°C instead of 24°C means your cooling is costing you about 30% more than it needs to. In a household spending $400/quarter on cooling, that's an extra $120/quarter — nearly $500/year. A ceiling fan running alongside air conditioning at 25°C often feels as comfortable as air conditioning alone at 22°C, at a fraction of the running cost.
Solar panels degrade over time — typically losing 0.5–0.8% of output per year. Inverters can fail silently. Shading from new trees or neighbouring construction can dramatically reduce output. And feed-in tariff rates change regularly — the rate you signed up on may not be the rate you're getting now. An annual check of your solar system's output (most inverters have an app or web portal) and a review of your feed-in tariff rate can identify hundreds of dollars in lost value.
BillDecoder reads your electricity bill and tells you exactly what you're paying, whether you're overpaying, and what you can do about it. It identifies your tariff type, checks your rates against the market, flags rebates you might be eligible for, and gives you specific savings actions with estimated dollar amounts. It takes 60 seconds, requires no forms or sign-up, and is completely free. Your bill is never stored.
The common thread across all of these: information is power. The moment you understand what you're paying and why, the savings become obvious. Your retailer has had this information all along. Now you do too.

It depends on your situation, but most Australians who haven't switched plans in the last 12 months can save $200–$600 per year just by switching to a better market offer. Add rebates, usage shifts, and standby power fixes, and savings of $500–$1,000 per year are common.
Do I need solar panels to save money?
No. Every tip on this list works without solar. Solar can provide additional savings, but the biggest wins for most households come from switching plans, claiming rebates, and shifting usage to cheaper hours.
Will switching retailers cause a blackout or interruption?
Never. Your electricity supply comes through the same poles and wires regardless of which retailer you're with. Switching is purely administrative — you won't notice any change except a lower bill.
