Two national giants, two different pricing shapes

<a href="/retailers/agl">AGL</a> and <a href="/retailers/origin-energy">Origin</a> are the two biggest energy retailers in Australia, and because both operate at national scale they compete hard on headline offers. But "big and national" does not mean "priced the same". They differ in the balance they strike between the daily supply charge and the usage rate, in how they structure discounts and sign-up credits, and in what they pay for exported solar. Any of those levers can make one cheaper than the other for a given household while the reverse is true next door.

The honest answer to "AGL or Origin?" is that it depends on your usage and your state. Both publish market offers priced against the reference price, both offer electricity and gas (so a dual-fuel household may value keeping them together), and both regularly refresh their deals. Neither is universally cheaper, which is precisely why you compare them on your own numbers rather than on a brand reputation.

What to compare between them, line by line

Start with the two building blocks: the daily supply charge and the usage rate. If you are a low user, the supply charge dominates your bill, so whichever retailer has the lower daily charge tends to win; if you are a high user, the usage rate matters more. Then look at the discount structure: is the headline saving guaranteed, or conditional on paying by the due date? A plan with a big pay-on-time discount only beats a plan with a smaller guaranteed one if you never miss a due date.

Next, check the solar feed-in tariff if you have panels, because a better feed-in rate can outweigh a slightly higher usage rate for a solar-heavy home. Finally, note the benefit period on each offer and what the rates revert to afterwards. Both retailers use benefit periods, so a plan that is cheapest today may not be in 13 months. These are the fields that decide it, not which brand you have heard of more.

Who each genuinely suits

AGL suits households that value a large, long-established retailer with a broad range of plans, solar and battery options, and app-based bill management, and who want electricity and gas under one roof. Origin, equally, suits people who want national coverage, dual fuel, and its own ecosystem of tools and rewards. In truth the two are more alike in what they offer than either’s marketing suggests; the meaningful difference on any given day is the price of the specific plan against your usage.

That is the point most comparisons miss. Because both change their offers regularly, the winner between AGL and Origin can flip month to month and postcode to postcode. There is no durable "AGL is cheaper" or "Origin is cheaper" answer. There is only cheaper for your usage, in your network, this month.

How to settle it on your actual bill

Rather than guess, cost both retailers’ plans against your real usage. EnergySorted reads your actual peak, off-peak and shoulder usage, your solar export and your gas steps from an uploaded bill, then costs every AGL and Origin plan (alongside every other AER-listed retailer) and ranks them cheapest-first. It proves the result against what you are paying now, so you see the real difference in dollars, not a headline percentage.

Because EnergySorted takes no retailer commissions (it is funded by a small subscription, around $39 a year) neither AGL nor Origin can pay to rank higher, and it re-checks nightly so you are told if the winner changes after your next benefit period ends.

Frequently asked questions

Is AGL or Origin cheaper?

Neither is universally cheaper. Both are large national retailers that price against the reference price and change their offers regularly. Which one is cheaper depends on your usage level, whether you have solar, your state and your tariff, so it can flip month to month and suburb to suburb.

What actually differs between AGL and Origin pricing?

The balance between daily supply charge and usage rate, whether discounts are guaranteed or conditional on paying on time, the solar feed-in tariff, sign-up credits, and the benefit period and revert rates. These line items decide the winner, not the brand.

Do both AGL and Origin offer gas as well as electricity?

Yes, both offer electricity and gas, so a dual-fuel household can keep both with one retailer. Whether that is cheapest still depends on the specific rates. Bundling is convenient but not automatically the lowest cost, and it is worth checking whether gas or electricity is cheaper to run for your appliances before committing.

Does having solar change which is better?

It can. For a solar-heavy home, the feed-in tariff can matter more than a small difference in usage rate, so the retailer with the better feed-in may win even if its usage rate is slightly higher. Our solar feed-in tariffs explained guide covers how the export credit works. This is exactly the kind of trade-off that only shows up when you compare on real usage.

Is it hard to switch between AGL and Origin?

No. Switching is largely paperwork the new retailer handles for you, there is no interruption to your supply, and most competitive plans have no exit fee. Our guide to electricity plans with no exit fees covers what to check before you move.

What happens when my AGL or Origin benefit period ends?

You are usually rolled onto the retailer's higher ongoing rates without a phone call, so a plan that was cheapest last year can quietly become expensive. Re-checking at least yearly is the fix, as our guide to how often to switch energy plans explains.

Are AGL and Origin the cheapest retailers overall?

Not necessarily. As the two largest retailers they compete hard, but smaller challenger retailers can undercut them on the right usage profile. A whole-of-market comparison decides it, since there is no single cheapest electricity retailer that wins for every household.

Do sign-up credits make one of them cheaper?

A one-off sign-up or bill credit lowers your first-year cost but says nothing about the ongoing rates once it is used up, so treat it as a bonus rather than the deciding factor. What matters over a full year is the usage rate, supply charge and any conditional discount, not a headline credit.

Is AGL or Origin better for EV owners?

Either can suit an EV household if it offers a strong off-peak or dedicated EV rate you can charge into overnight. The right choice depends on the specific tariff, not the brand. Compare the options in our best electricity plans for EV owners guide.

How do their standing-offer prices compare?

Both cap their standing offers at the government reference price, so their default plans are broadly similar and rarely the cheapest thing either sells. The real competition is in their market offers priced below it, as our Default Market Offer explained guide covers.

How do I know which one wins for my household?

Cost both on your actual bill. EnergySorted reads your real peak/off-peak/solar usage and ranks every AGL and Origin plan cheapest-first against your current bill, commission-free, so you see the true dollar difference rather than a marketing claim. Upload a bill to compare and see the result in dollars.
