Energy bills are a growing concern for Australian businesses. With prices varying wildly across providers, locations, and contracts, it’s no surprise many business owners ask: Who is the most expensive energy provider?
It’s a fair question — but also a misleading one.
The truth is, the highest-cost provider isn’t always obvious from advertised rates alone. That’s because true energy costs are shaped by more than just cents per kilowatt hour. Billing structures, daily supply charges, demand penalties, and contract conditions all play a role.
That’s why more businesses are working with an energy broker — not just to avoid the most expensive deals, but to secure contracts that suit their specific usage, timing, and risk tolerance.
Let’s break it down.
Who Is the Most Expensive Energy Provider in Australia?
According to recent Canstar Blue research, the most expensive residential energy retailers (in terms of average annual bill) tend to be the legacy providers — especially those with large customer bases and fewer incentives to compete aggressively on price.
For example:
- In New South Wales, EnergyAustralia and Origin tend to sit at the higher end for flat-rate usage plans.
- In Victoria, AGL and some network-aligned retailers have higher average bills compared to emerging challengers like Tango or ReAmped.
- South Australian businesses often pay more across the board due to supply constraints and a smaller retailer pool.
But averages don’t tell the whole story. The “most expensive” provider for one business might offer excellent rates to another, depending on:
- Load profile
- Location
- Contract length
- Time-of-use alignment
That’s where a qualified energy broker makes a measurable difference.
Why Advertised Rates Can Be Deceiving
Many energy retailers promote introductory offers or discounts — but those offers often include:
- Conditional discounts (e.g. pay on time or lose the discount)
- Rates that expire after 12 months
- Plans that exclude large usage customers
- Separate charges for demand, controlled loads, or network fees
The result? What looks cheap upfront can end up being costly over time, especially for businesses with:
- High demand spikes (e.g. commercial kitchens, gyms, manufacturers)
- Large daily base loads (e.g. 24/7 operations)
- Multiple meters or sites under one ABN
In these situations, choosing the wrong plan can mean overpaying by thousands per year.
That’s exactly why more businesses are using an energy broker to vet not just the provider — but the plan.
Real Case: The Cost of Picking Based on Brand Recognition
A medium-sized print business in Sydney had been with a well-known energy provider for years, renewing contracts out of convenience. On the surface, their plan included a 15% discount and fixed usage rates — which seemed competitive.
But a broker reviewing their bills uncovered that the plan carried unusually high demand charges during 3pm–8pm — the business’s busiest period.
After switching to a lesser-known supplier with a time-of-use plan better suited to their load curve, the business saved just over $5,600 in one year — even though the advertised rate was higher than their previous provider’s.
Lesson? Sometimes the “most expensive” provider isn’t about the rate — it’s about the wrong match.
The Role of an Energy Broker in Avoiding Overpriced Plans
An energy broker works for your business — not the retailers. Their job is to:
- Analyse your past usage and meter data
- Identify which retailers penalise your load profile
- Compare real-world quotes, not just advertised plans
- Recommend plans that avoid unnecessary fees
- Time your contract entry to align with favourable wholesale pricing
This hands-on approach means you’re not just avoiding the most expensive providers — you’re aligning with the right one.

It’s Not Just About Price — It’s About Fit
Let’s say Retailer A offers 28.5c/kWh and Retailer B offers 29.3c/kWh. Retailer A looks cheaper, right?
But if:
- Retailer A has higher supply charges
- Their peak pricing window covers your business hours
- They don’t support solar export or have poor customer service
…then Retailer B may actually save you more in the long run.
The same applies to retailers with low usage charges but steep exit fees, or no flexibility for growth. An energy broker helps you weigh these elements properly, so you don’t fall for the rate trap.
What About Green Plans?
Many of the most expensive commercial plans are green-labelled contracts, which include carbon offsets or renewable investment surcharges.
If sustainability is a priority for your business, these plans may be worth it. But not all “green” plans are priced equally — or transparently.
Brokers can:
- Help you access renewable-linked wholesale plans
- Break down the cost vs benefit of GreenPower
- Advise on blended contracts (e.g. 50% green, 50% standard)
For some businesses, green tariffs are a reputational investment. For others, they’re an unnecessary expense.
Again, the best decision comes from real analysis — not assumptions.
Final Thoughts: Don’t Focus on “Most Expensive.” Focus on “Most Suitable.”
So, who is the most expensive energy provider? The honest answer: it depends on your business.
What matters more is whether your contract aligns with:
- When you use electricity
- How much you use
- What flexibility you need
- Whether you require sustainable supply
The worst outcome isn’t choosing a pricey retailer — it’s choosing a bad-fit plan, even from a cheap one.
And the smartest way to avoid that? Work with an energy broker who looks past the marketing and helps you find real value, not just low rates.
Because energy isn’t just a bill — it’s a strategy.
