EnergyAustralia vs Radian Energy: Which Is Cheaper for QLD Households in 2026?

SaveNest Editorial Team · 2026-10-19 · 8 min read

If you are weighing up EnergyAustralia vs Radian Energy, the honest answer to "which is cheaper for QLD households in 2026" is that it depends on your network area, your tariff type, when you use power and whether you have solar. Retail prices change often, and a headline discount on one plan can cost more than a smaller discount on another. This guide shows you how to compare the two properly, what to look for in each offer, and how to avoid the common traps. We don't quote exact rates here because they vary by postcode and change frequently.

Why a simple "who is cheaper" answer does not exist

EnergyAustralia is one of Australia's largest energy retailers, with a long-running presence in the market and plans in south-east Queensland. Radian Energy is a smaller player. Large and small retailers often compete in different ways: big retailers tend to offer bundled perks, wide plan choice and established customer service channels, while smaller retailers sometimes compete on a lower usage rate or a simpler plan. That is a general pattern, not a guarantee, and either retailer may change what it offers at any time.

Before comparing, confirm on the government comparison site, Energy Made Easy, that each retailer is currently selling to your postcode and on your meter type. Retailer availability in Queensland varies by region.

Know your Queensland network first

Queensland is split into two main distribution areas, and this matters more than the retailer brand:

South-east Queensland (Energex network): This is a competitive retail market. Retailers publish their own offers, and the Default Market Offer (DMO), set each year by the Australian Energy Regulator, acts as a price cap on standing offers. Brisbane, the Gold Coast, the Sunshine Coast and Ipswich are in this area.
Regional Queensland (Ergon Energy network): Pricing here works differently, and retail choice is more limited. Regulated tariffs are set by the Queensland Competition Authority. If you live in regional Queensland, check which retailers can actually supply you before spending time on comparisons.

For a state-level overview, see our Queensland electricity guide.

The five numbers that decide which retailer is cheaper

1. Usage rate (cents per kWh)

This is what you pay for every unit of electricity you consume. Many Queensland households are on a single-rate tariff, though time-of-use and demand tariffs are also common. Compare the same tariff type across both retailers. Comparing one retailer's flat rate with another's time-of-use rate tells you nothing.

2. Daily supply charge

You pay this every day regardless of how much power you use. A low usage rate with a high supply charge can cost more for a low-consumption household, such as a unit or a household that is often away. A high-usage family home benefits more from a low usage rate.

3. Discounts and conditions

Discounts are the most misunderstood part of any plan. Check:

Whether the discount applies to usage only, supply only, or the whole bill.
Whether it is a "pay on time" or "guaranteed" discount. A pay-on-time discount disappears if you pay late.
Whether the discount is calculated off the DMO or off the retailer's own base rates. A "20% off" plan with higher base rates may beat nothing.
Whether the discount ends after the benchmark period, and what the rate becomes afterwards.

4. Solar feed-in tariff

If you have rooftop solar, what the retailer pays you for exported power can swing your annual cost by hundreds of dollars. Feed-in tariffs vary widely by retailer, and some plans only pay a reasonable feed-in rate if you accept a higher usage rate. Weigh the two together. If you are considering panels, you can get a free solar savings estimate.

5. Fees and contract terms

Look for exit fees, late payment fees, payment processing fees and whether the plan is a fixed-term or ongoing contract. Under the national rules, you should be told in advance when a fixed benefit period is ending.

How EnergyAustralia and Radian Energy typically differ

Without relying on any single advertised price, here is what to weigh when you put the two side by side:

Plan variety: A large retailer usually offers more plan types (flat rate, time of use, solar-focused, batteries or EV-focused). A smaller retailer may have fewer options, which can make comparison simpler but may not suit every household.
Pricing approach: Smaller retailers sometimes aim for sharper headline rates to win customers. Larger retailers may rely on discounts, bundled benefits or loyalty features. Whichever is cheaper in practice depends on your usage.
Customer service and billing: Check app and online account features, billing options and how easy it is to reach a person. These do not show in a rate comparison but affect your experience.
Financial hardship and concessions support: All licensed retailers must have a hardship policy. If you receive a concession, confirm how the retailer applies it.

Treat these as questions to check, not conclusions. Always confirm that each retailer holds a current licence and read the Energy Price Fact Sheet for the exact plan.

A worked method to compare them in 15 minutes

Find your latest bill and note your total kWh for the period, the number of days, your tariff type and your current rates.
Enter your postcode and a recent bill into Energy Made Easy, or use a comparison tool that accepts your usage.
Shortlist one EnergyAustralia plan and one Radian Energy plan on the same tariff type.
Download each Energy Price Fact Sheet and calculate the annual cost yourself: (usage rate × yearly kWh) + (daily supply × 365), then subtract the discount only if you will meet its conditions.
If you have solar, add your expected export credits using the feed-in tariff.
Compare the totals, then check exit fees and the length of any benefit period.

This method matters because the plan with the best-looking headline discount is often not the cheapest once supply charges, conditions and feed-in credits are included.

Common mistakes Queensland households make

Staying on the same plan for years. Rates and discounts tend to erode over time, and the best offers usually go to new customers. Checking at least once a year is worthwhile.
Ignoring time-of-use rates. If most of your use is in the evening peak, a time-of-use plan may cost more than a flat rate. If you run appliances during the day or have solar, it can save money.
Chasing discounts you won't meet. If you often pay late, a pay-on-time discount is worth nothing.
Forgetting concessions and rebates. Eligible Queenslanders may receive state or federal electricity rebates. Check with the Queensland Government and with your retailer that they are applied.
Comparing only electricity. If you also use gas, internet or mobile services, a bundle may or may not save money. Compare separately first via gas, internet and mobile deals.

Who is likely to save most with each type of retailer?

Low-usage households (units, singles, couples): The daily supply charge matters most. Look for the lowest supply charge.
Large family homes with air conditioning: Queensland summers push up usage, so the usage rate and any discount on usage will dominate your bill.
Solar households: Feed-in tariff and daytime rates matter most. Do not choose on usage rate alone.
Households with an EV or battery: Look for time-of-use or dedicated EV/battery plans, and check whether the retailer offers them.

Beyond price: how to judge a retailer fairly

The cheapest plan is not always the best value if the retailer is hard to deal with. Read the plan's fact sheet, check for clear billing, and use independent sources such as the Energy and Water Ombudsman Queensland to understand how complaints are handled. Avoid relying on unverified review claims. If a salesperson or website quotes a savings figure, ask what usage and tariff it assumes.

Steps to Take

Gather your latest bill and note your kWh usage, number of days, tariff type, supply charge and any solar export figures.
Confirm your network area (Energex or Ergon) and check which retailers, including EnergyAustralia and Radian Energy, can supply your address.
Compare like-for-like plans on Energy Made Easy and calculate the annual cost of each using the fact sheet rates, including only discounts you will actually earn.
Check the fine print for exit fees, the benefit period, feed-in tariff and how the plan changes after any discount ends.
Switch if the saving is real, then set a calendar reminder to review your plan again in 12 months.

Disclaimer: Energy rates, discounts and retailer offers change often. Figures vary by retailer, plan and postcode, so always compare current offers before you switch.
