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

SaveNest Editorial Team · 2026-10-18 · 8 min read

If you live in South East Queensland and are weighing up EnergyAustralia vs COVAU, the honest answer to "which is cheaper for QLD households in 2026" is that it depends on your household's usage, your tariff type and which specific plan you compare. Neither retailer is cheaper in every situation. This guide explains how the two typically differ, what drives the real cost on your bill, and how to run a fair comparison in about ten minutes.

Disclaimer: electricity rates, discounts and conditions change often and vary by network area and meter type. Treat this as a guide to comparing, not a rate sheet, and always check current offers before you switch.

First, Check Whether You Can Choose a Retailer

Queensland has two very different markets. In South East Queensland, which is the Energex network area covering Brisbane, the Gold Coast, the Sunshine Coast, Ipswich and surrounds, you can choose between many retailers, and both EnergyAustralia and COVAU are options to consider. In regional Queensland on the Ergon Energy network, retail competition is limited and most households are on regulated prices set by the Queensland Government, so there is often little or no retailer choice. Before you spend time comparing, confirm your network from your latest bill or by entering your postcode into a comparison tool.

Who Are These Two Retailers?

EnergyAustralia

EnergyAustralia is one of Australia's largest energy retailers, often grouped with AGL and Origin as the "big three". It sells electricity and gas, has a long operating history and offers a wide range of plans, including flat-rate, time-of-use, and plans with solar feed-in tariffs. Larger retailers tend to offer a broad product range and established customer service channels, and their headline rates often include pay-on-time or other conditional discounts.

COVAU

COVAU is a newer, digital-first retailer. Smaller and newer retailers frequently compete on simplicity, online-only service and sharper headline pricing, sometimes with fewer plan variations. Because newer retailers change their offers regularly, always read the current Energy Price Fact Sheet rather than relying on what a plan looked like a year ago.

Being smaller or larger does not make a retailer cheaper or better. What matters is the plan's price structure and your own usage.

What Actually Determines Which Is Cheaper

When people compare EnergyAustralia and COVAU for Queensland households, they tend to compare headline discounts. That is a mistake. Your bill is built from several components, and a plan that wins on one can lose on another.

Usage rate (cents per kWh): what you pay for each unit of electricity. Often there is a first tier at a higher or lower rate, then a second tier after a set amount per day.
Daily supply charge: a fixed amount you pay every day regardless of use. For low-use households such as small units or people away often, this can matter more than the usage rate.
Conditional discounts: pay-on-time, direct debit or e-billing discounts. These are usually applied to some or all charges. If you miss the condition, you lose the discount, so the "discounted" price may not be what you pay.
Solar feed-in tariff: what you are credited for exports. Retailers vary widely, and a high usage rate paired with a low feed-in tariff can cost solar households more than they expect.
Controlled load tariffs: separately metered loads such as hot water or a pool pump. Check that the plan supports your existing setup and what rate it charges.
Fees and incentives: exit fees, paper bill fees, payment processing fees, or sign-up credits. Credits can look attractive but may be one-off and do not change your ongoing rate.

Which Household Types Tend to Suit Which Plan Style?

Without quoting specific rates, which change regularly, here is how to think about the likely winner for different homes.

Low-usage households (units, apartments, singles)

Your daily supply charge is a big share of your bill. Compare supply charges first. A plan with a slightly higher usage rate but a lower daily charge can be cheaper overall for you.

Families with high daytime or evening use

Usage rates and any tiering matter most. Check how many kWh per day fall into the first tier and what happens beyond that. If you run air conditioning through a Queensland summer, your second-tier rate may be the number that decides your bill.

Households with rooftop solar

Look at both sides of the meter: the rate you pay for imported power and the feed-in tariff you receive. Queensland has high solar uptake, and feed-in tariffs differ considerably between retailers. A strong feed-in tariff may justify a plan with an average usage rate if you export a lot. If you are thinking about adding panels or a battery, you can also get a free solar savings estimate.

Households with time-of-use meters

If you have a smart meter, time-of-use plans charge different rates for peak, shoulder and off-peak periods. They can save money if you shift laundry, dishwashing and EV charging to cheaper periods, but cost more if most of your use falls in peak times. Compare the exact peak windows each retailer uses, as they are not always identical.

How to Do a Fair EnergyAustralia vs COVAU Comparison

The most common error is comparing a "per year" estimate shown on a website that was built for a generic household, not yours. For a fair comparison, you need to use your own numbers.

Find your latest bill and note your average daily usage in kWh, your billing days, and whether you have solar or a controlled load.
Note your network (Energex or Ergon) and whether your meter is flat or time-of-use.
For each plan, pull up the Energy Price Fact Sheet, which retailers are required to provide. It lists the usage rates, supply charge, discounts and fees in a standard format.
Calculate the discounted and undiscounted cost over a year using your usage, and ask yourself whether you will reliably meet the discount conditions.

For SEQ households, the Default Market Offer (DMO) set by the Australian Energy Regulator acts as a reference price for standing offers. Many market plans are advertised as a percentage below the DMO. This is useful for orientation, but "10% off the DMO" is not the same as "cheapest", since the reference is an annual figure for a typical usage level and your actual saving depends on your usage.

Common Traps When Switching in Queensland

Expiring discounts: some plans have benefit periods after which rates rise. Note the end date and diarise it.
Sign-up credits that mask a higher rate: a one-off credit of, say, a few dozen dollars does not make up for a higher ongoing rate over twelve months.
Feed-in tariff changes: some retailers reduce feed-in rates over time. Check whether the rate is fixed and for how long.
Forgetting the meter type: a time-of-use plan on a household that mainly uses power at night can be more expensive than a flat rate.
Ignoring government support: Queensland and federal cost-of-living measures, concessions and rebates have changed from year to year. Check what you are eligible for through the Queensland Government, as these are applied to your account regardless of which retailer you choose, though how they show on your bill can vary.

Is It Worth Switching at All?

Often, yes. If you have been with the same retailer for more than a year or two and have not renegotiated, you may be on a rate that has drifted well above current market offers. Even if neither EnergyAustralia nor COVAU is the cheapest option in your area, comparing them against others usually reveals a meaningful difference. Switching is free in most cases, there is no interruption to your supply, and the same network (Energex or Ergon) continues to maintain the poles, wires and meters regardless of who bills you.

It is also worth asking your current retailer for a better deal. Some will match or improve on their offers if you say you are comparing, though results vary.

Steps to Take

Get your latest bill and note your network, daily usage in kWh, billing days, meter type, and any solar or controlled load.
Request or download the Energy Price Fact Sheet for the EnergyAustralia and COVAU plans available at your address, and compare usage rates, daily supply charges and feed-in tariffs side by side.
Calculate your yearly cost with and without conditional discounts, and only count a discount if you will reliably meet its conditions.
Check the fine print on benefit periods, exit fees, sign-up credits and how long any feed-in tariff is guaranteed.
Compare against other retailers on our electricity deals page, since the cheapest plan for you may not be from either of these two.
Switch and diarise the end of any discount period so you can review again in 12 months.
