Fact-checked against Energy Made Easy – federal comparison site on 2026-04-25.
Of all the bills that land in an Australian household, power is the one where what you pay and what you could pay drift furthest apart. And the reason that gap sticks around is simple: sitting down to check your plan feels like a chore, so most of us never do it. The price feels fixed. It isn’t. Run the numbers through the federal Energy Made Easy comparison site and the same pattern keeps showing up – plenty of households are paying 15-30% more than the cheapest competitive offer for exactly the usage they already have. Left alone, that gap doesn’t close on its own.
Why “the energy bill is what it is” hides the actual price
Most of Australia runs a competitive retail energy market. Several retailers can sell you electricity and gas, and each sets its own prices and plan structures. The Australian Energy Regulator sets a Default Market Offer (DMO) in the states it covers – think of it as a regulated price ceiling – but retailers are free to pitch market plans that sit above or below that line, depending on the deal.
And the headline cents-per-kilowatt-hour rate is only one piece of the puzzle. Your actual annual cost comes out of everything stacked around it: the fixed daily supply charge, time-of-use tariffs, discounts you only get if you pay on time, savings tied to direct debit, and exit fees buried in the contract. Add those together and the “cheap” plan isn’t always the cheap one.
For the official picture, the Australian Energy Regulator’s main site carries the regulatory detail. But the tool you actually want is the federal Energy Made Easy portal – it cuts through the marketing and gives you a genuine apples-to-apples comparison.
What’s actually on a typical electricity bill
Pull apart a typical Australian electricity bill and you’ll find the same handful of line items. Here’s what each one does, and which way it pushes your total:
| Line item | What it is | Effect on your bill |
|---|---|---|
| Supply charge (daily fixed) | A daily amount paid regardless of usage, covering connection to the grid. Often c. 80-130 cents per day depending on retailer and location. | Adds (charged even if you use nothing) |
| Usage charge | Cents per kilowatt-hour for electricity consumed. Can be flat-rate or time-of-use. | Adds (scales with what you use) |
| Concessions and rebates | Automatic deductions for eligible card holders (state-specific). | Reduces |
| Solar feed-in credit | For households exporting solar energy to the grid. | Reduces |
| Discounts | Typically conditional (pay-on-time, direct debit) and usually applied to the total bill or the usage portion. | Reduces (only if you meet the condition) |
| GST | Added to the total. | Adds |
The supply charge is the one most people skip over, and it’s the one worth a second look. It’s fixed, so the less power you use, the bigger a share of your bill it becomes. For a low-usage household, that daily charge can quietly end up being the single largest component – even though it barely rates a mention in any retailer’s marketing.
Tariff types and how they work
The usage portion of your bill is shaped by your tariff. There are four common types in Australia, and which one suits you comes down to when you actually use power.
Flat (single-rate) tariff
One cents-per-kWh rate, all day, every day. Simple and predictable. You’ll find it on plans for households without a smart meter, and on plenty of straightforward smart-meter plans too.
Time-of-use (TOU) tariff
Here the rate changes through the day: peak (usually afternoon and evening), off-peak (overnight), and shoulder in between. Shift your heavy use to the cheap hours – washing overnight, charging the EV after midnight, running the pool pump off-peak – and your bill can drop. Keep loading up the grid during peak and it goes the other way.
Demand tariff
This one charges you on your single highest 30-minute spike during peak times each month, on top of your usage rates. Run several big appliances at once on a hot afternoon – a few air conditioners going together – and it gets expensive fast. Still fairly rare, but turning up on more plans.
Controlled-load tariff
A cheaper rate for specific appliances – usually electric hot water – that are wired so the retailer can switch them on remotely during off-peak hours. Common in older houses running electric hot water.
So which beats flat-rate? It depends entirely on your habits. A household leaning on daytime air-conditioning often does better on a flat rate, while one charging an EV overnight usually wins on time-of-use. Here’s how the four compare:
| Tariff | How it charges | Tends to suit |
|---|---|---|
| Flat (single-rate) | Same rate any time of day | Households with significant daytime air-conditioning; anyone who wants predictability |
| Time-of-use | Peak, off-peak and shoulder rates by time of day | Households that can shift use to off-peak – overnight washing, EV charging, pool pumps |
| Demand | Usage rates plus a charge on the highest 30-minute peak each month | Households with steady, spread-out use – and a trap for occasional big simultaneous loads |
| Controlled-load | Cheaper rate for a remotely controlled appliance | Older houses with electric hot water |
Comparison and switching providers
When you want to compare plans, the federal Energy Made Easy site is the one to use. Feed it your postcode, a recent bill (for your actual usage), your tariff type and a few household details, and it hands back a ranked list of every available plan with an estimated annual cost matched to how you actually use power.
Switching is usually painless. Here’s how it runs:
- Sign up with the new retailer online or by phone
- The new retailer notifies the old retailer and arranges the transition
- No interruption to power supply – only the billing entity changes
- Final bill from the old retailer covers the period until the switch date
- Most plans have no exit fees, but some legacy plans do – worth checking
One caveat: competition isn’t everywhere. In Western Australia outside the South West Interconnected System, in the Northern Territory, and across some regional areas, there’s little or no retail choice. The local utility is often the only game in town, and your options to switch are limited.
Concessions and the energy supplement
If money’s tight, there are a few ways the system can knock your energy costs down. There are three to know about.
State-level energy concessions
Every state and territory runs its own energy concession scheme for eligible card holders – the Pensioner Concession Card, Health Care Card, and the like. Once you’ve registered your card details, the retailer usually applies the concession automatically. The amount varies by state, but it commonly runs to several hundred dollars a year.
The federal Energy Supplement
The Energy Supplement is a small extra payment that lands automatically with most Centrelink income-support payments and DVA payments. You don’t apply for it separately – it’s baked into the underlying payment.
Hardship programs
If you’re struggling to keep up with bills, retailers in most states have to offer a hardship program. That can mean a payment plan, a much lower risk of disconnection, and a path to crisis support. Each retailer publishes the details of its program on its own site and on the energy ombudsman sites.
The eligibility for the underlying concession-eligibility cards is covered in our government health benefits eligibility article.
Water and other utilities
Water and sewerage work differently. They’re run by state-owned utilities – Sydney Water, SA Water, Hunter Water and the rest – with no retail competition. Prices are regulated rather than set by the market, and within a given service area you don’t get to choose your provider.
If you rent, your water deal depends on the lease:
- In some leases, the landlord pays water rates and the tenant pays usage above a threshold
- In others, the tenant pays everything including rates
- Specifics are in the lease and governed by state tenancy law
Internet and mobile are a different story again – both run on competitive national markets, with plenty of retailers selling fixed broadband over the shared NBN. Of all the household utilities, telco has been the quiet good-news line: on equivalent plans, prices have generally drifted down over the past decade as competition has built up.
Frequently asked questions
Why are utility bills so different between providers in Australia?
Most Australian states have competitive retail energy markets – multiple retailers can sell electricity and gas to consumers, each setting their own prices and structures. Differences come from supply costs, fixed daily supply charges, usage tariffs, discounts, and contract terms. The federal Energy Made Easy comparison site shows price differences between offers for the same usage profile.
Can I switch energy providers in Australia?
In most states, yes. The retail energy market is competitive, and switching is typically simple – usually a sign-up online or by phone, with the new retailer handling the transition. Some states (like Western Australia and parts of regional Australia) have less or no retail competition, where switching options are limited.
What is the energy supplement and who gets it?
The Energy Supplement is a small additional payment automatically added to certain Centrelink and Veterans’ Affairs payments. It’s intended to help recipients with energy costs. It applies to most pension and allowance payments and doesn’t require a separate application – it’s added automatically when the underlying payment is granted.
The single check that pays for itself
If you do one thing with your bills each year, make it this: take last quarter’s electricity bill (and gas, if you have it) and run it through Energy Made Easy. The site uses the real usage and tariff structure off your bill to work out what that exact usage would cost on every other plan available in your area. Already on the cheapest? You get a clean confirmation. Paying meaningfully more? You get a ranked list of cheaper options, sorted by estimated annual savings.
If it’s worth switching, the whole thing takes about ten minutes online. And it’s worth doing regularly, because the Australian Bureau of Statistics’ CPI utilities component shows energy prices have moved substantially in some recent years. A plan that was a good deal when you signed up can quietly stop being one. An annual check is the sensible default.
On a concession card, add one more annual habit: confirm the card is still registered with your retailer and that your state concession is actually being applied. These don’t always carry across when you move house or switch retailers, and clawing back missed concessions after the fact is far harder than getting them right from the start.
What to check, in order
If you’re sitting down to sort your bills, this is the order that gets the most value for the least effort:
- Run last quarter’s bill through Energy Made Easy. This is the one check that can move your whole annual cost, and it takes minutes.
- Read the supply charge first. It’s fixed and easy to ignore, yet for a low-usage household it can be the largest single component of the bill.
- Match your tariff to your habits. Daytime air-conditioning tends to favour flat-rate; overnight EV charging tends to favour time-of-use.
- Check that conditional discounts actually apply to you. Pay-on-time and direct-debit savings only count if you’ll genuinely meet the condition.
- Confirm concessions and rebates are registered. If you hold an eligible card, make sure the retailer has it on file and the state concession is showing on the bill.
- Watch for exit fees before switching. Most plans have none, but some legacy plans do – check before you sign.
A quick worked example (Illustrative only)
To see why the supply charge deserves a look, picture two households on the same plan. Illustrative only – the figures below use this article’s own ranges, not a real quote.
Say the daily supply charge sits at the top of the range quoted above, around 130 cents per day. Over a year that’s about 130 cents x 365 days, or roughly $474.50 in fixed charges – paid before a single kilowatt-hour of usage is counted. A heavy user barely notices it as a slice of a large bill. A light user, with little usage on top, can find that fixed charge is the biggest line on the page. Same plan, very different experience – which is exactly why comparing on total estimated annual cost (the way Energy Made Easy does it), rather than on the advertised usage rate alone, matters. And it’s the same logic behind the 15-30% gap above the cheapest competitive offer noted at the top: the headline rate rarely tells you the whole story.
