There is no single best electricity provider in Australia, and any list that claims otherwise is selling you something. The cheapest plan for you depends on how much power you use, which network area you live in, and whether you have solar on the roof, so the only honest answer is to compare offers against the reference price using your own bill.
That sounds like a cop-out. It is not. Two households on the same street can be best served by two different retailers, because their usage patterns and solar setups differ. The good news is that the comparison is more straightforward than the retailers would like you to believe, once you know which numbers actually matter.
Why “best” is the wrong question
Electricity retailers compete on a confusing mix of headline discounts, sign-up credits, and conditional offers. The marketing is designed to make comparison hard. What you are really buying is a combination of two charges: a usage rate measured in cents per kilowatt hour, and a daily supply charge that you pay regardless of how much power you use.
A plan with a big advertised discount can still cost you more than a plain-looking competitor if its underlying rates are high. The discount is applied to an inflated base, which is a very old trick. So the right question is not “who is the best provider” but “which plan gives me the lowest total cost for my actual usage in my area”.
Anchor everything to the reference price
The single most useful tool you have is the government reference price. In most of the country this is the Default Market Offer, set each year by the Australian Energy Regulator. In Victoria it is the Victorian Default Offer. Retailers must show their plan as a percentage above or below this benchmark, which finally gives you a like-for-like comparison.
A plan advertised as “20 per cent below the reference price” is genuinely cheaper than one at “10 per cent below” for a typical user in the same area. Use that percentage as your first filter, then read past it to the actual rates. These benchmarks were last checked June 2026, and they are reset annually, so confirm the current figure before you sign.
A note on the obvious: this is general information, not personal financial advice. Your circumstances are your own, and the numbers below are illustrative.
Read the fine print that actually costs money
Once you have a shortlist, the traps are predictable. Here is what to check before you commit.
- Usage and supply rates. Look at the cents per kilowatt hour and the daily supply charge together. A low usage rate with a high daily charge can suit a heavy user and punish a light one.
- Benefit periods. Many discounts expire after 12 months, after which your rate can quietly jump. Diarise the end date.
- Conditional discounts. Some discounts only apply if you pay on time or by direct debit. Miss one and the saving vanishes.
- Exit fees and contract terms. Most market offers have no exit fee, but check, especially on fixed-rate or “locked in” plans.
- Sign-up credits. A one-off credit is nice, but spread across a year it rarely beats a structurally cheaper plan.
If the discount is doing the talking, the rates are usually doing the taking.
Compare against your own bill
Headline percentages get you partway, but the gold standard is comparing offers against your real consumption. The government comparison sites let you do exactly that. Use Energy Made Easy for most states, or Victorian Energy Compare if you are in Victoria. Punch in your usage from a recent bill, or upload the bill itself, and the site ranks live offers by what you would actually pay.
These sites are free, independent, and they do not take commissions, which is more than can be said for some of the commercial comparison services that only list paying partners. If you want a deeper walk through trimming the bill itself, our guide on how to lower your electricity bill covers the behavioural levers that sit alongside switching.
If you have solar, the retailer matters less
Solar changes the maths entirely. For a solar home, the biggest savings come from using your own power during the day rather than from the retailer you pick. Every kilowatt hour you self-consume is one you do not buy at the full retail rate, which is far more valuable than the feed-in tariff you earn for exporting.
That feed-in tariff has fallen sharply across most networks in recent years, so chasing the retailer with the highest export rate is often a false economy if it comes bundled with high usage rates. We unpack the trade-offs in our explainer on the solar feed-in tariff in Australia. The bigger structural decision is sizing the system itself, and it is worth taking time to size a solar system to cut your bill so that your generation matches your daytime load. A battery can shift even more of that solar into the evening peak, though the economics vary by household.
The table below is a rough guide to what should weigh most in your decision.
| Your situation | What matters most | What matters least |
|---|---|---|
| No solar, average user | Usage rate vs reference price | Sign-up credits |
| No solar, low user | Daily supply charge | High export rates |
| Solar, daytime usage | Self-consumption, usage rate | Feed-in tariff |
| Solar, evening usage | Feed-in tariff or a battery | Headline discount |
Figures and benchmarks above were last checked June 2026. Energy policy, default offers and feed-in tariffs change regularly, often each financial year, so always confirm current offers directly with the retailer and check the official regulator and government comparison sites before deciding.
The bottom line
The best electricity provider is the one whose plan costs you the least for your actual usage in your actual network area, and that is a personal answer, not a leaderboard. Anchor every offer to the reference price, read past the discount to the real usage and supply rates, watch for benefit-period and conditional-discount traps, and compare against your own bill on the government site. If you have solar, focus on using your own power before you fuss over the retailer. Do that, and switching becomes a 20-minute job that can save real money, no spreadsheet PhD required.
