Two big-three retailers, compared fairly

<a href="/retailers/agl">AGL</a> and <a href="/retailers/energyaustralia">EnergyAustralia</a> are both members of Australia’s "big three", both retail electricity and gas nationally, and both price their market offers against the government reference price. That shared scale means they compete directly, but it does not make their prices identical. They differ in how they balance the daily supply charge against the usage rate, in whether discounts are guaranteed or conditional, in sign-up credits, and in what they pay for exported solar.

As with every retailer pairing, the honest verdict is "it depends". AGL may be cheaper for one household and EnergyAustralia for another in the same street, purely because of different usage patterns, and the answer can change when either updates its offers. The point of comparing them is not to crown a permanent winner but to find which one is cheaper for your bill, right now.

What to actually compare

Look at the daily supply charge and usage rate together. If you use little power, the fixed supply charge is the bigger share of your bill and the retailer with the lower daily charge tends to win; if you use a lot, the usage rate carries more weight. Then examine the discount: a headline pay-on-time (conditional) discount is only worth its face value if every bill is paid by the due date, whereas a guaranteed discount always lands.

Solar households should weigh the feed-in tariff, which can offset a higher usage rate. And check the benefit period on each plan plus the rates it reverts to. Both retailers use time-limited offers, so today’s cheapest plan can quietly become expensive in a year. Comparing these specific fields, rather than the brand, is what tells you which retailer wins.

Who each genuinely suits

AGL suits households that want a large, established retailer with a wide plan range, solar and battery products, and app-based management, plus the option to bundle gas. EnergyAustralia suits people who want the same national reliability and dual fuel, and who prefer its particular plan mix, which at times includes fixed-rate or bill-smoothing options that appeal to households wanting predictability. Both are solid mainstream choices rather than niche specialists.

Because both refresh their offers regularly, neither holds a lasting price advantage. The cheaper of the two shifts with your usage, your network area and the calendar. So treat any blanket "AGL beats EnergyAustralia" claim with caution. It is only ever true for a particular household at a particular moment.

Let your bill decide

EnergySorted removes the guesswork. Upload a recent bill and it costs every AGL and EnergyAustralia plan against your real peak, off-peak and shoulder usage, your solar export and your gas steps, ranks them cheapest-first alongside the rest of the AER-listed market, and proves the result against your current bill in real dollars.

It takes no retailer commissions. You pay a small subscription (around $39 a year), so neither retailer can buy a higher spot. And it re-checks nightly, flagging the moment a benefit period ends or a cheaper plan appears.

Frequently asked questions

Is AGL or EnergyAustralia cheaper?

There is no fixed answer. Both are large national retailers pricing against the reference price, so which is cheaper depends on your usage, solar, state and tariff, and can reverse when either updates its offers. The only way to know is to compare both on your real usage.

How do their charging models differ?

They set the supply-charge-to-usage-rate balance differently, use different discount types (guaranteed vs pay-on-time), offer different sign-up credits and solar feed-in rates, and apply their own benefit periods with different revert rates.

Does EnergyAustralia offer fixed-rate plans?

EnergyAustralia has at times offered fixed-rate or bill-smoothing style options that appeal to households wanting predictable costs. Availability changes, so check current offers, and remember a fixed rate is about certainty, not a guarantee of being the cheapest.

Can I bundle gas with either?

Yes, both are dual-fuel retailers, so you can hold electricity and gas with either AGL or EnergyAustralia. Bundling is convenient, but whether it is the cheapest option still depends on the specific rates for your usage, and it is worth knowing how to save on your gas bill separately before assuming a bundle wins.

Does having solar change which is cheaper?

It can. A solar-heavy home is effectively paid back at the feed-in rate, so a retailer with a better feed-in can win even with a slightly higher usage rate. Our solar feed-in tariffs explained guide covers how the export credit offsets your bill.

What happens when the benefit period ends?

Both retailers use time-limited offers, and when the benefit period expires you are usually moved onto higher ongoing rates without a reminder. That silent revert is why so many households overpay, and why our guide to how often to switch energy plans recommends a yearly re-check.

Do AGL or EnergyAustralia charge exit fees?

Most competitive market plans have no exit fee, though it is always worth reading the terms of the specific plan. Our guide to plans with no exit fees explains what to look for so you are not locked in.

Are these two cheaper than smaller retailers?

Not always. Big brands compete on scale and product range, but lean challengers can undercut them for some households. See big retailers vs small challengers for the trade-offs, and compare the whole market rather than assuming a familiar name is cheapest.

Which suits a low-usage apartment?

A low user pays proportionally more in the fixed daily supply charge, so whichever retailer has the lower supply charge often wins for a small household, even if its usage rate is a little higher. Our guide to choosing an electricity plan in an apartment covers what else to check.

Is either better for EV owners?

Either can suit an EV owner if it has a strong off-peak or dedicated EV rate for overnight charging, which is where the specific tariff matters far more than the brand. See our best electricity plans for EV owners guide to weigh them up.

What is the most reliable way to compare them?

Cost both on your actual bill. EnergySorted ranks every AGL and EnergyAustralia plan cheapest-first against your real usage and current bill, commission-free and re-checked nightly, so you see the genuine winner for your household. Upload a recent bill to get your answer in dollars.
