Rising energy prices have made “cheapest supplier” one of the most Googled terms in Australia’s business community. But the truth is: there’s no one-size-fits-all answer. Whether you run a suburban gym, an inner-city café, or a multi-site retail group, the cheapest energy supplier for your business depends on a mix of usage, timing, and contract structure.
That’s where an energy broker can make a serious difference.
Let’s unpack what makes one supplier “cheaper” than another — and why savvy business owners are leaning on brokers to help them cut through the noise, compare deals properly, and make cost-saving decisions that actually stick.
Cheap Energy Isn’t Just About Cents Per kWh
On the surface, comparing suppliers might seem simple. Just find the lowest rate, sign the contract, and move on — right?
Wrong. Because in energy pricing, the lowest headline rate doesn’t always mean the best value. Factors like:
- Peak vs off-peak usage
- Demand charges
- Tariff structures
- Network fees
- Contract flexibility
- Green energy premiums
…can all flip the equation.
For example, a supplier offering 24.5c/kWh might sound better than one offering 25.2c/kWh — but if the latter includes lower demand charges or better off-peak discounts, it may actually cost less overall.
This is where an experienced energy broker becomes critical — they don’t just scan rates, they calculate real-world impact.
The Role of an Energy Broker in Comparing Rates
Energy brokers work as intermediaries between suppliers and businesses. Their job is to:
- Analyse your energy usage (daily and seasonal patterns)
- Compare quotes from multiple suppliers
- Break down the fine print in each contract
- Match the right tariff structure to your load profile
- Negotiate pricing, terms, and benefits on your behalf
Instead of dealing with multiple sales reps and trying to compare apples to oranges, you get a shortlist of customised options.
Let’s say you run a bakery in Geelong that’s busiest between 3am and 11am. A broker may find that the “cheapest” plan for your business is one with heavily discounted early morning off-peak rates — even if the flat rate is slightly higher than other offers.
You don’t get that level of nuance from a simple online quote tool.
Supplier Prices Change by Location
Australia’s energy market is divided by regions and distribution zones. This means the cheapest energy supplier in Sydney might not even operate in Perth or Hobart.
According to the Australian Energy Regulator, electricity prices can differ based on the state, network provider, and whether your usage qualifies as small or large business consumption.
So, who’s the cheapest? Here’s a general idea based on recent data:
| State | Common Low-Cost Suppliers (2024) |
|---|---|
| NSW | Red Energy, Energy Locals |
| VIC | GloBird, Tango Energy |
| QLD | AGL, EnergyAustralia (with promos) |
| SA | Lumo Energy, Alinta Energy |
Note: These are general averages. Your specific usage, demand profile, and timing may lead to very different results.

Don’t Forget Demand Charges and Contract Traps
The biggest trap many businesses fall into? Choosing a supplier based on unit price, only to get stung later with unexpected demand charges or early termination fees.
Demand charges penalise businesses for sharp spikes in usage. If you turn on multiple pieces of equipment at once — say, a printing press and HVAC system — your bill could jump even if your consumption is otherwise low.
Some brokers specialise in analysing this load pattern data and choosing a contract that minimises these charges — potentially saving thousands per year.
In contrast, a standard online quote comparison won’t flag this. Nor will most supplier sales reps.
Real-World Example: Childcare Centre Avoids a Pricing Trap
A Brisbane-based childcare centre was quoted a low fixed rate from a national energy retailer. It looked good on paper — cheaper than their current plan by 3.5 cents per kWh.
But an energy broker reviewed the fine print and noticed an unusually high peak demand threshold. Given that the centre ran dishwashers, washing machines, and heating systems around the same times each day, the demand penalties could’ve cost them more than $2,000 annually.
The broker sourced a different supplier with a more forgiving tariff structure. Slightly higher rate — but no peak demand risk. Result? Real savings, fewer billing surprises.
Should You Always Use a Broker?
Not always. If you’re running a small home-based operation or a one-room office with very predictable usage, you may find the best rate yourself through direct contact with a supplier.
But if you:
- Use more than 10,000 kWh per year
- Have large seasonal or daily fluctuations
- Operate across multiple locations
- Want support understanding your bill or tracking usage
- Need help comparing plan structures or green energy options
…then working with a broker can pay off — quickly.
The value they provide isn’t just about price, but about choosing the right structure. The broker’s role becomes even more important when exploring wholesale-linked contracts, solar feed-in tariffs, or carbon offsetting plans.

Final Word: Cheapest Isn’t Always Smartest
There’s a difference between cheap and low total cost.
The cheapest energy supplier may offer a tempting rate — but if the contract doesn’t suit your business needs, it could cost you far more over time.
The right strategy? Understand your usage. Get expert advice. Compare multiple offers based on your real consumption profile. And make sure someone has your back when you sign the dotted line.
Whether you’re operating a small business or managing multiple sites, a smart contract backed by proper analysis is where real savings begin.
