AGL vs Origin vs EnergyAustralia vs Red Energy: which retailer for Australia 2026

Australian electricity retail is dominated by four brands: AGL, Origin, EnergyAustralia, and Red Energy. Between them they hold the majority of residential connections across the National Electricity Market (New South Wales, Victoria, Queensland, South Australia, Tasmania, ACT). Each markets itself heavily, and the front-page pricing looks similar. Underneath, the real differences are in solar feed-in tariffs, benefit-period expiry behaviour, customer service, and green energy options.

This 2026 guide compares the four on the decisions Australian households actually make: pick the cheapest plan for my postcode and usage, switch when a benefit period ends, choose a solar-friendly retailer, or select a carbon-neutral option.

The verdict

For 2026 Australia, Red Energy leads on customer service and 100 percent Australian call centres (owned by Snowy Hydro, a federally owned corporation), which explains its consistent Canstar Blue customer satisfaction wins. Origin wins on solar and multi-product bundling with Solar Boost plans and electricity-gas-broadband bundles. AGL is strongest on green energy plans with a Climate Active carbon-neutral electricity option available across most residential plans. EnergyAustralia is competitive on flat-rate no-frills usage for households that want a simple bill without solar or bundling.

Why the choice matters more in 2026

Australian residential electricity is regulated at the wholesale, network, and retail layers, and each layer moves independently. Wholesale prices rose in most states through 2025 to 2026 as ageing coal plants continued to exit and gas peaker generation set the market price more often. Network charges (poles and wires) rose in New South Wales and Victoria as distribution businesses funded grid upgrades. Retail margins stayed roughly stable.

The result: from 1 July 2026, most Australian households on Default Market Offer or Victorian Default Offer tariffs saw bill increases. Households on market plans with expiring benefit periods faced even larger jumps, because the market plan reverts to a much higher standing-offer rate at benefit-period end. This makes retailer switching or renegotiation more valuable in 2026 than in most previous years.

The reference-price framework simplifies comparison. Since 2019, all market plans in DMO and VDO regions must be quoted as a percentage above or below the government-set reference price. A plan saying "10 percent below reference" is directly comparable to a plan saying "12 percent below reference" from a different retailer, holding usage constant. This is a big improvement over the pre-2019 world of confusing "48 percent off usage" style discounts.

How the four retailers stack up

Retailer	Ownership	Where they lead	Solar strength	Green energy	Typical customer-service rank
AGL	ASX-listed	Green energy plans, national reach	Solid, Solar Savers Plus	Carbon-neutral option	Mid
Origin	ASX-listed	Solar and multi-product bundling	Strong, Solar Boost	GreenPower opt-in	Mid
EnergyAustralia	CLP Group (Hong Kong)	Simple flat-rate plans	Average, Solar Home Bundle	PureEnergy add-on	Mid to lower
Red Energy	Snowy Hydro (federal-owned)	Customer service, Australian call centres	Adequate, Solar Saver	Blue add-on	Consistently top of Canstar Blue

AGL

AGL Energy Limited is one of Australia's oldest energy companies, tracing back to the Australian Gas Light Company in 1837. It is ASX-listed (ticker AGL) and operates across the National Electricity Market plus retail gas in most southeast states.

Where AGL wins. Green energy plans. AGL offers a Carbon Neutral Electricity option on most residential plans, using Climate Active-certified offsets. For customers who want to reduce their household emissions footprint but do not have room for rooftop solar, this is the most accessible green product from the Big Four. AGL Solar Savers Plus is competitive on first-band feed-in tariff (the exports paid at the higher rate before the tariff steps down).

Where AGL loses. Customer service ranks below Red Energy in most independent surveys, and AGL's historical size means it has a large legacy customer base on older, less competitive market plans. Households that signed onto AGL 3 to 5 years ago and never renegotiated are often paying substantially more than new AGL customers on the current headline plan.

Where AGL sits on price. Middle to lower end of the Big Four range in most states, competitive with Origin. Verify the current published rate on the AGL residential plan page for your postcode.

Origin

Origin Energy Limited is Australia's largest energy retailer by residential customer count. It is ASX-listed (ticker ORG) and operates electricity, gas, LPG, and (through partnerships) home broadband. Origin also runs a natural gas exploration and production business and a stake in Australia Pacific LNG.

Where Origin wins. Solar and multi-product bundling. Origin Solar Boost plans include an above-market first-band feed-in tariff for the initial daily solar export, tapering down after a set threshold. For households with 6.6 kW to 10 kW rooftop systems, this often results in the highest net savings across the Big Four on a modelled year. Origin's Broadband + Electricity + Gas bundling gives modest bundle discounts and single-bill convenience.

Where Origin loses. Customer service, while improved, still lags Red Energy in Canstar Blue rankings. Some households report benefit-period expiry causing bill shock when a headline "20 percent below reference" plan reverts to standing-offer.

Where Origin sits on price. Middle of the Big Four in most states, with strong solar-inclusive plans that pull the annual cost down for solar households.

EnergyAustralia

EnergyAustralia Pty Ltd is Australia's third-largest energy retailer by residential customers. It is wholly owned by CLP Group, a Hong Kong-listed utility conglomerate. EnergyAustralia operates coal, gas, and hydro generation as well as retail.

Where EnergyAustralia wins. Simple flat-rate plans. EnergyAustralia's Total Plan and Basic Home plans are structured for households that do not have solar, do not want tiered usage complexity, and just want a predictable bill. Anytime pricing (single rate across the day) is available in most states, which suits households on the road during the day.

Where EnergyAustralia loses. Solar plans are less competitive than Origin or AGL for first-band feed-in. Green energy add-ons (PureEnergy) are more expensive per kWh than AGL's Carbon Neutral Electricity approach. Customer service satisfaction tracks close to AGL and Origin, meaningfully below Red Energy.

Where EnergyAustralia sits on price. Middle to slightly higher end of the Big Four, depending on state. On flat-rate no-frills plans, competitive with AGL and Origin.

Red Energy

Red Energy Pty Ltd is wholly owned by Snowy Hydro Limited, which is itself wholly owned by the Australian federal government. Red operates electricity retail in New South Wales, Victoria, ACT, and South Australia, and does not sell gas in most states.

Where Red Energy wins. Customer service. Red consistently tops Canstar Blue's electricity retailer customer satisfaction survey in most states, driven by call centres located in Melbourne and Sydney (staffed by Australian employees) and simple, low-jargon bills. For customers who value being able to phone a real Australian representative when something goes wrong, Red is the clearest choice among the Big Four.

Where Red Energy loses. No gas in most states means Red cannot compete on dual-fuel bundles where Origin and AGL can. Solar feed-in tariff is mid-pack rather than sector-leading; households with large rooftop solar may find Origin's Solar Boost or AGL's Solar Savers Plus pays back more on modelled exports.

Where Red Energy sits on price. Middle to lower end of the Big Four in New South Wales and Victoria, benefiting from Snowy Hydro's generation cost base. Verify the current published rate on the Red Energy residential plan page for your postcode.

The reference price framework explained

Since July 2019, all market plans sold in New South Wales, South Australia, and south-east Queensland must quote against a reference price set by the Australian Energy Regulator: the Default Market Offer. Victoria uses a parallel system, the Victorian Default Offer, set by the Essential Services Commission.

The reference price is calibrated to a standardised "average" household usage in each network zone. Retailers must then express market plans as a percentage above or below this reference. A plan "10 percent below reference" saves that percentage on the standardised usage assumption; your actual bill may vary if your usage differs from the standardised profile.

Practical implication: comparing "12 percent below reference at Origin" vs "10 percent below reference at AGL" is a fair apples-to-apples comparison, assuming similar tariff structure (both single-rate or both time-of-use). Comparing "12 percent below reference" to "48 percent off usage" (an older pre-reform pricing frame) is not fair; the older frame typically overstates the saving.

Solar and feed-in tariffs

Solar feed-in tariffs (FiT) have compressed across all four retailers as daytime wholesale prices have fallen. In 2026, headline FiT rates from AGL, Origin, EnergyAustralia, and Red Energy typically sit in the range of 4 to 10 cents per kWh for the first tier of exports. Higher rates on smaller export bands taper down for larger exports; this is called a stepped tariff and now dominates Big Four solar offers.

The honest solar retailer question is not "which has the highest headline FiT" but "which pays the most across my modelled annual export profile". For a household with a 6.6 kW system exporting 8 to 10 MWh a year, the retailer choice can differ by $200 to $400 across a full year, depending on postcode and time-of-use variation.

Solar retailer comparison rules:

1. Estimate your annual export in kWh from your last three quarterly bills.
2. Split into likely first-band vs above-first-band.
3. Multiply by the retailer's respective FiT rate for each band.
4. Add the retail rate savings on daytime self-consumption.
5. Compare across retailers on the same modelled year.

Green energy options

AGL Carbon Neutral Electricity matches your usage with Climate Active carbon offsets across the full year. Cost premium is modest compared to standard plans; the offsetting mechanism is external audit-verified.

Origin GreenPower opt-in is government-certified via the GreenPower program. Customers pay a per-kWh premium to have that percentage of their usage matched with certified renewable generation. This is the highest-integrity green energy option because GreenPower is a regulated scheme rather than an offset arrangement.

EnergyAustralia PureEnergy is similar in structure to Origin's GreenPower opt-in, with slightly different pricing.

Red Energy Blue is an add-on to Red plans that funds Snowy Hydro's renewable generation portfolio. Structure is more like AGL's approach than Origin's; the exact certification varies by product.

The correct choice depends on how much you value certification granularity. For maximum integrity: Origin GreenPower or EnergyAustralia PureEnergy (both government-certified). For simple carbon neutrality: AGL Carbon Neutral Electricity.

Contract types and benefit periods

Australian residential electricity contracts do not carry exit fees (since 2019 reforms). All four retailers offer month-to-month market contracts you can leave at any time without penalty. What varies is the benefit period: the window during which the headline percentage-below-reference price applies.

Typical benefit periods: 12 months from plan start. At the end, the plan rolls to a standing-offer rate that is significantly higher (often 15 to 25 percent above the initial market rate).

Retailer behaviour at benefit-period end: some retailers proactively offer a fresh benefit period on the same plan; some do not. Set a calendar reminder for month 11 to review your rate.

Verdict by household type

Renter household on grid-only usage: Red Energy for customer service and simplicity, or Origin's flat-rate market plan if you want the lowest annual bill.

Owner-occupier with rooftop solar (6.6 kW plus): Origin Solar Boost. Highest first-band feed-in in most postcodes across the Big Four, with the caveat that the ranking rotates so verify on Energy Made Easy for your postcode.

High-usage household (large family, pool): Compare Origin, AGL, and Red on Energy Made Easy with your actual usage profile. High-usage households often benefit most from time-of-use tariffs paired with off-peak electric hot-water and pool-pump scheduling; Origin and AGL have well-structured time-of-use plans.

Sustainability-focused household without solar: AGL Carbon Neutral Electricity for automatic offsetting, or Origin GreenPower opt-in for government-certified renewable matching.

Dual-fuel household (electricity plus gas): Origin or AGL for the bundling discount; EnergyAustralia is competitive in Victoria specifically. Red does not sell gas in most states.

Household on a fixed low income: Red Energy for the direct customer support relationship, and always verify eligibility for state concessions on electricity bills. Concessions apply to any retailer once your Health Care Card details are registered.

Small business owner working from home: Consider a small-business tariff rather than residential; this is a separate comparison. AGL and Origin dominate the small-business electricity market with dedicated small-business plans.

What to check before you switch

1. Your actual usage in kWh from your last four quarterly bills. This is more informative than the retailer's estimate.
2. Reference-price percentage for the new plan vs old plan. A "20 percent below reference" plan is only better than "15 percent below reference" if the tariff structure is comparable (both single-rate or both time-of-use).
3. Benefit-period length and what the standing rate rolls to.
4. Solar feed-in tariff structure if you have rooftop solar. First-band vs above-first-band rate, and the daily export threshold.
5. Bundling (electricity plus gas plus broadband, if applicable). Bundling discounts are modest (3 to 8 percent) but real.
6. State concessions. If you hold a Health Care Card, Pensioner Concession Card, or DVA card, register with the new retailer to preserve state government concessions.

Common mistakes

Chasing headline percentage without checking usage profile. The "48 percent off usage" pricing common pre-2019 was misleading in most households. The 2019 reference-price framework is much more honest but still assumes a standardised usage profile. If your household is very high or very low usage, your actual saving vs the headline can differ.

Staying on the same retailer at benefit-period end. Retailers rarely proactively offer better rates to existing customers. New-customer plans are almost always cheaper than legacy plans; renegotiate or switch every 12 months.

Ignoring solar export bands. A "12 cents per kWh" solar feed-in rate is often only for the first 5 to 10 kWh a day; the balance is paid at 4 to 6 cents. Model your actual export against the stepped tariff.

Not registering concessions. State government electricity concessions can save $200 to $350 per year for eligible households; they do not transfer automatically when you switch retailers.

Confusing GreenPower with carbon-neutral. GreenPower is regulated renewable-matching; carbon-neutral is offsetting-based. Both are legitimate but different products.

Frequently asked questions

Which is the cheapest electricity retailer in Australia in 2026, AGL, Origin, EnergyAustralia, or Red Energy?

There is no single cheapest retailer nationally because pricing varies by distribution network (postcode) and by contract type. Under the 2026 Default Market Offer and Victorian Default Offer, market plans from all four Big Retailers must be quoted as a percentage below or above the reference price. Red Energy and Origin often lead on headline market-plan pricing for average usage in New South Wales and Victoria; AGL is competitive in Queensland and South Australia; EnergyAustralia sits mid-pack in most states. Compare like-for-like on Energy Made Easy for your postcode before switching.

What is the Default Market Offer and how does it affect the Big 4 energy retailers in 2026?

The Default Market Offer (DMO) is a maximum standing-offer price set annually by the Australian Energy Regulator for New South Wales, South Australia, and south-east Queensland. Victoria uses a separate Victorian Default Offer (VDO) set by the Essential Services Commission. From 1 July 2026, DMO prices rose in most zones due to wholesale and network cost pressures. AGL, Origin, EnergyAustralia, and Red Energy must express market plans as a percentage difference from the reference price, which makes cross-retailer comparison much cleaner than pre-2019 discount structures.

Which energy retailer has the best solar feed-in tariff in 2026?

Solar feed-in tariffs (FiT) have compressed across all four retailers as daytime wholesale prices have fallen. In 2026, headline FiT rates from AGL, Origin, EnergyAustralia, and Red Energy typically sit in the range of 4 to 10 cents per kWh for the first tier of exports, with higher rates on smaller export bands and lower rates on larger. Origin's Solar Boost plans and AGL's Solar Savers Plus are among the more competitive at the entry band. FiT rates are a moving target; compare on Energy Made Easy for your postcode before switching.

Is Red Energy really 100 percent Australian?

Red Energy is wholly owned by Snowy Hydro Limited, which is itself owned by the Australian federal government. Red Energy operates its call centres in Melbourne and Sydney rather than offshore, which is one of the reasons it consistently tops Canstar Blue and independent customer-satisfaction surveys for electricity retailers in Australia. AGL, Origin, and EnergyAustralia are all publicly listed or foreign-owned, with a mix of onshore and offshore customer support.

Which energy retailer has the best green energy options in Australia?

AGL offers a Carbon Neutral Electricity option on most residential plans, backed by Climate Active carbon offsets. Origin's Green Electricity plans certified under GreenPower let customers pay a premium to have a percentage of usage matched with renewables. EnergyAustralia's PureEnergy and Red Energy's Blue add-ons work similarly. All four support the government's Small-scale Renewable Energy Scheme (SRES) which underpins rooftop solar rebates. If you want deep green, GreenPower-certified plans are the honest option.

How do I compare electricity plans across AGL, Origin, EnergyAustralia, and Red Energy in 2026?

Use Energy Made Easy (energymadeeasy.gov.au), the free government comparison tool run by the Australian Energy Regulator, or the Victorian equivalent (compare.energy.vic.gov.au) if you live in Victoria. Enter your postcode and typical usage (from your latest bill) and the tool returns all available plans sorted by annual cost. This is more honest than commercial comparison sites, which often show only retailers that pay commissions. Compare AGL, Origin, EnergyAustralia, and Red Energy against three or four smaller retailers before switching.

Can I earn cashback when switching electricity retailers via ShopBack?

ShopBack lists energy retailer switching offers in its finance category (shopback.com.au/finance) from time to time. Bonus cashback for new energy plan sign-ups rotates through the four Big Retailers and smaller challengers across the year. Check shopback.com.au/finance for the current active offers before you switch. Your electricity retailer choice should still be driven by the annual bill total on Energy Made Easy, not the switching bonus alone.

What are the exit fees and contract lengths for these retailers?

Australian residential energy contracts have not carried exit fees since national reforms in 2019. AGL, Origin, EnergyAustralia, and Red Energy all offer no-lock-in market contracts, with plan variations lasting 12 to 24 months but no penalty for switching mid-term. Fixed-price benefit periods (usually 12 months) can end abruptly, so track your benefit-period end date and switch or renegotiate before it expires to avoid rolling to a higher rate.

Do the Big 4 energy retailers offer dual-fuel (electricity plus gas) discounts?

AGL, Origin, and EnergyAustralia all offer dual-fuel plans (electricity plus gas) with modest bundle savings, typically 3 to 8 percent off one or both. Red Energy sells electricity only in most states and does not offer gas, so it cannot bundle. Dual-fuel bundles are honest only in states with reticulated gas (Victoria, New South Wales, South Australia, parts of Queensland). If you use bottled LPG, the dual-fuel discount is not applicable.

How often should I review my electricity plan in Australia?

Once a year, timed to your bill anniversary or to July when Default Market Offer resets. Retailer market plans typically include a benefit period (12 months of a headline percentage below reference price); when that ends, your rates can jump. Review at end of benefit period and either renegotiate the same plan or switch to a fresh benefit period. Retailers rarely proactively offer better rates to existing customers; new-customer plans are almost always cheaper than legacy ones.

Key takeaways

• Red Energy leads on customer service and 100 percent Australian call centres, owned by federally owned Snowy Hydro.
• Origin wins on solar and multi-product bundling with Solar Boost feed-in and electricity-gas-broadband bundles.
• AGL is strongest on green energy plans (Climate Active carbon-neutral option) and competitive on price in most states.
• EnergyAustralia is a solid mid-pack pick for flat-rate no-frills households; less competitive on solar.
• Australian residential contracts have no exit fees; switch or renegotiate every 12 months at benefit-period end.
• Compare on Energy Made Easy or the Victorian equivalent before switching; commercial comparison sites often show only commission-paying retailers.
