How to find the best electricity retailer in Australia

There is no single best retailer — only the best plan for your usage. Here is how to compare properly and avoid the marketing traps.

Why "the best retailer" is the wrong question

People often want to be told which retailer is best, as if one company is cheapest for everyone. It does not work that way. Retailers set dozens of different plans, price them differently by network area, and change rates regularly. The retailer that is cheapest for a solar household in Adelaide might be among the most expensive for a renter in western Sydney.

The better question is: which plan is cheapest for my usage, right now, in my network area? Brand loyalty, a familiar logo, or a big advertising campaign tell you nothing about whether a plan is good value for you. The best retailer is simply whoever offers the best plan for your specific pattern of use — and that can change from year to year.

The marketing traps to avoid

Headline discounts
A "40% off" claim is off a reference price that varies — a smaller discount off a lower base can be cheaper. Compare dollars, not percentages.
Conditional discounts
Pay-on-time or direct-debit discounts only apply if you meet the condition every time. Miss one and the "discount" vanishes.
Benefit periods
Many market offers discount for 12 months, then step up. The plan that looked cheapest can quietly become expensive.
Sign-up perks
Gift cards and credits are one-offs. A slightly higher rate can erase a $75 welcome credit within a couple of bills.
Low usage rate, high supply charge
A cheap-looking c/kWh paired with a high daily fee can cost more overall, especially for low-usage homes.
Paid shortlists
Many comparison sites only show retailers that pay them a commission, so the cheapest plan for you may never appear.

How to compare properly

  1. Compare on total annual cost for your real usage — not on discounts, percentages or headline rates.
  2. Include every charge: supply charge, usage rates across all tariff periods, controlled load and solar feed-in.
  3. Check the whole market, not a commission-paid shortlist, so you actually see the cheapest option.
  4. Read the benefit period and any conditions, so a cheap first year does not become an expensive second one.
  5. Re-check periodically — the best plan a year ago is often not the best today.

Where EnergySorted fits

EnergySorted is built for exactly this problem. It compares 16,000-plus plans from every AER-listed retailer — not a paid shortlist — and it takes no retailer commissions. You pay a small yearly fee (around $39 at the time of writing), which means it answers to you, not to the retailers. That removes the biggest conflict of interest in energy comparison.

Crucially, it does not rank on headline rates. It costs every plan against your real usage from an uploaded bill — your peak and off-peak split, controlled load, and solar feed-in — so the "best retailer" it points you to is the one that is genuinely cheapest for your household, with a savings guarantee to back it.

Frequently asked questions

Who is the cheapest electricity retailer in Australia?

There is no single cheapest retailer for everyone — it depends on your usage, tariff and network area, and it changes as retailers adjust rates. The only reliable answer comes from costing plans against your own usage. Any fixed "cheapest retailer" claim dates quickly.

Are the big-name retailers more expensive?

Not necessarily, and not always. Brand size tells you little about value. Big retailers sometimes have very competitive plans and sometimes do not; the same is true of smaller ones. Judge the plan on cost for your usage, not the logo.

Why do comparison sites show different results?

Many only list retailers that pay them a commission, so their "best" is limited to their paying partners. EnergySorted takes no retailer commissions and compares every AER-listed plan, so its results are not filtered by who pays it.

Should I just pick the plan with the biggest discount?

No. Discounts are quoted off different reference prices and are often conditional or time-limited. A smaller discount off a lower base can be cheaper overall. Always compare on total annual cost for your usage, not on the discount headline.

How often should I re-check the best retailer?

At least once a year, and whenever your bill jumps or a benefit period ends. The cheapest plan changes as retailers adjust rates, so last year’s best is often not this year’s. Tracking it over time makes this effortless.
