Rising power bills have many Australian businesses asking the same question: Which electricity provider is the cheapest? On paper, it should be an easy answer. But in practice, energy pricing is anything but straightforward. Tariffs vary across states, usage profiles affect what “cheap” means, and the fine print in contracts can undo even the most promising headline rates.
That’s why more businesses are relying on one thing to get clarity: an energy broker.
Let’s unpack what makes one provider cheaper than another, how brokers do the legwork that most businesses can’t, and why the real answer depends on more than just cents per kilowatt hour.
Price Is Just the Start — Not the Whole Picture
Electricity rates are often presented in cents per kilowatt hour (kWh), and that’s what most business owners focus on. But the cheapest deal isn’t just about the rate. It’s about the structure behind that rate.
A few examples:
- Time-of-use tariffs may offer lower off-peak pricing but hit hard during business hours.
- Demand charges can penalise businesses for spikes in usage — even brief ones.
- Contract length can tie you into higher rates over time, despite initial discounts.
- Daily supply charges vary widely and can make a big difference for low-usage sites.
A true comparison needs to factor in your actual energy usage, peak load times, and flexibility needs. That’s exactly what a professional energy broker does.
What an Energy Broker Actually Does
An energy broker is an independent consultant who works with businesses to source better energy deals. Rather than selling electricity, they help buyers:
- Review their energy bills and smart meter data
- Compare offers from multiple retailers
- Understand the tariff structures and contract terms
- Negotiate rates and contract conditions
- Provide ongoing advice if better rates appear later
Because brokers deal with retailers daily, they often access wholesale-linked deals or unlisted commercial tariffs the average business owner can’t find on their own.
That’s especially helpful if your energy needs vary by season, site, or opening hours — because the best deal for a 24/7 warehouse won’t suit a Monday-to-Friday accounting firm.

Case Study: A Franchise Group Cuts Costs by Centralising Contracts
A Melbourne-based fast-food franchise had energy contracts spread across five suppliers. Each store was on a different plan, with different billing cycles and inconsistent rates.
They brought in an energy broker to audit usage and consolidate deals.
The result:
- Standardised contracts across all sites
- Shifted to a supplier offering a bulk-use discount
- Moved to a hybrid flat-rate/time-of-use model that suited peak meal times
- Saved over $6,000 annually — without changing operations
The broker managed the supplier switch, handled all paperwork, and set reminders for renewals.
Who Actually Offers the Cheapest Rates?
According to the Australian Energy Regulator, electricity pricing in Australia varies widely by region and usage class.
Here are general trends from recent data:
| State | Common Low-Cost Providers (2024–25) |
|---|---|
| VIC | GloBird Energy, Tango Energy |
| NSW | Energy Locals, ReAmped Energy |
| QLD | AGL (for large loads), Powershop |
| SA | Lumo Energy, Origin Energy |
But here’s the catch — the cheapest provider for one postcode may not even offer service in another. And even within the same provider, contract offers can vary significantly depending on your business profile and energy consumption volume.
That’s where a trusted energy broker comes in — comparing not just which provider is cheapest, but which tariff within that provider’s offerings will work best for you.
Tariffs That Sound Cheap But Cost More
Retailers know how to market. That means many businesses get pulled into offers with eye-catching low rates but end up spending more due to hidden conditions.
Common traps:
- Low usage rates paired with high supply charges
- Time-limited discounts that disappear after 12 months
- Tiered pricing that penalises higher usage volumes
- Exit fees that lock you in if a better deal emerges
An energy broker helps you avoid these traps by comparing total contract cost, not just rate per unit.
Can’t I Just Use a Comparison Site?
Public energy comparison sites can be useful — but they’re limited. They often:
- Show residential or small-business plans only
- Don’t account for your detailed usage profile
- Don’t factor in volume discounts for multi-site clients
- Exclude wholesale-linked pricing or custom commercial deals
- Offer no help interpreting contract clauses
A broker offers full-market access, custom analysis, and real advice. For larger users or multi-location operations, that edge can translate into five-figure savings annually.
When Should You Engage a Broker?
If you:
- Haven’t reviewed your energy contract in the past 12 months
- Operate in multiple locations
- Have variable or peak-heavy energy usage
- Want to explore green or wholesale-linked contracts
- Are expanding or relocating
…then bringing in a broker could pay for itself almost instantly.
They’ll not only find the cheapest electricity provider for your situation — they’ll ensure the deal actually works for your business.
Final Take: Cheapest Isn’t Always Obvious
So, which electricity provider is the cheapest? The honest answer: it depends.
Your postcode, your load profile, your peak hours, your ability to shift demand — they all play a part. What matters most is choosing a deal that fits your business like a glove, not just grabbing the lowest rate on the list.
And the smartest way to do that? Work with an energy broker who lives and breathes these comparisons — so you don’t have to.
Let the experts do the heavy lifting. That’s how businesses turn guesswork into savings.
