Your electricity distributor sets the underlying network charges for using the local poles, wires and capacity. Your retailer buys energy, manages the contract and sends the bill. Switching retailer does not change the distributor attached to your site, but it can change the contestable rates, margins, fees and contract terms wrapped around that same connection.
That distinction matters because business owners often waste time arguing about a line no retailer controls, while missing the lines that are genuinely open to competition.
I’m Joe from Smarta Switch in Brisbane. When I mark up a bill, the first job is separating three buckets: network costs, retailer-controlled costs, and government or market pass-through costs. Once those buckets are clear, you know what to quote, what to challenge and what to reduce through usage or tariff changes.
We’re paid by the energy retailer when you switch, never by you.
The one-minute version
- Distributor: owns the local network and determines the network tariff for the connection.
- Retailer: sells electricity to the business, sets the contract terms and sends the bill.
- Switching retailer: changes the seller and contract, not the poles, wires or distributor.
- Network charge saving: usually comes from the right tariff, lower demand or corrected data, not from asking another retailer to delete the network cost.
- Retail charge saving: comes from comparing the full commercial offer, not only the headline cents per kWh.
In South East Queensland, Energex is the distributor for most Brisbane and coastal SEQ sites. A business can switch from one retailer to another and Energex still operates the same local network. In regional Queensland the distributor is generally Ergon Energy Network. Other states have their own distribution areas, and the site address decides which one applies.
How the money moves from your bill to the market
One electricity bill collects several different costs.
The retailer is the business you have a supply contract with. It bills you for the account, but not every dollar on the invoice is revenue the retailer gets to keep.
Part of the bill recovers the cost of energy purchased for your usage. Part pays the distributor for network access. Part covers environmental schemes, metering and market costs. GST sits over the taxable total. The retailer then applies the rates, fees and commercial terms set out in your agreement.
On a small-business bundled offer, those inputs may be combined into a few simple lines. On a larger C&I agreement, they are more likely to be unbundled so the contestable and pass-through components are visible separately.
The Essential Services Commission has described large commercial contracts in much the same way: network charges are non-contestable pass-through costs, while wholesale energy, environmental and retail operating costs are shown as separate inputs. The exact bill layout still varies by retailer and contract.
That is why two bills can describe the same underlying cost in different ways. Always compare the calculation, not just the label.
What network charges pay for
Network charges fund the infrastructure and services that move electricity from the high-voltage grid to the site. That includes poles, wires, substations, transformers, local network operation, maintenance and the capacity needed to serve demand.
The Australian Energy Regulator sets revenue allowances and regulates network pricing for the networks it oversees. Distributors publish tariff structures and assign connections to tariffs under their approved rules.
For a business, network costs can include:
- a fixed daily or monthly charge
- a usage charge based on kWh
- time-of-use network rates
- a demand charge based on peak kW or kVA
- capacity or connection-related charges for larger sites
- metering or service lines, depending on the arrangement
Not every business gets every line. A small shop on a simple flat tariff will look very different from a warehouse with interval metering and a monthly demand charge.
The detailed breakdown is in our guides to Queensland business electricity tariffs and commercial demand charges.
What the retailer controls
The retailer competes for your account. The commercial offer can include:
- the energy usage rate
- peak, shoulder and off-peak retail rates
- the retailer’s margin
- daily supply or account charges
- demand-rate treatment in the retail agreement
- metering and service fees
- contract length
- price review or escalation clauses
- exit terms
- billing, payment and credit terms
- green product options
Some lines are fully contestable. Others are underlying pass-through costs with contract wording that controls how and when they are passed on.
For example, the distributor’s published network tariff is not invented by the retailer. But a quote still needs to say whether network costs are passed through at cost, bundled into another rate, adjusted when the distributor changes its tariffs, or subject to another commercial treatment.
That distinction matters on longer agreements. A low energy rate can look attractive while an indexation clause or a loosely worded pass-through clause shifts more cost later.
What actually changes when you switch retailer
When a business in a contestable market changes retailer:
- the physical supply stays connected
- the distributor stays the same
- the NMI stays the same
- the meter usually stays in place
- the retailer contract changes
- the retailer name and account details on the invoice change
- the contestable rates, fees and terms can change
There is no crew replacing poles or rewiring the premises. The transfer is a market and billing process.
The network tariff will normally carry across because it belongs to the connection and its classification, not the retailer’s brand. If the new bill presents the line differently, that does not automatically mean the tariff changed.
This is one reason supply does not stop during a standard retailer transfer. Read how long it takes to switch business energy for the timing and meter-read process.
Can you reduce network charges if they are not negotiable?
Yes. “Not negotiable” does not mean “nothing can be done”.
Check the tariff classification
A site can remain on a tariff that no longer suits the way it uses electricity. The business may have expanded, reduced hours, installed solar, changed equipment or moved from steady load to sharp peaks.
Changing network tariff is not the same as switching retailer. It usually requires a proper review against interval data and the distributor’s eligibility rules. The cheapest-looking tariff on one month can cost more over a full year, so model it before applying.
Reduce the peak that sets demand
Demand charges are often based on the highest measured interval in a billing period or another defined window. One short spike can set the charge for the month.
Staging motors, refrigeration, HVAC, ovens, compressors or charging loads can lower the peak without reducing production. The right move depends on the tariff and the site’s load profile.
Correct bad data or billing treatment
Estimated reads, incorrect multipliers, duplicated charges and meter configuration errors are not everyday events, but they do happen. Compare the bill to interval data and previous periods before assuming a sudden network increase is legitimate.
Review capacity settings on larger sites
Some C&I sites carry capacity or demand settings established during fitout or a higher-use period. If the site has permanently changed, there may be a case for review under the network’s rules. This needs evidence and is not automatically approved.
The trap in comparing only cents per kWh
Imagine two retailers quote the same business.
Retailer A offers a lower usage rate. Retailer B is slightly higher on usage but lower on the daily supply charge and demand treatment. If the business has modest annual usage but a large demand peak, Retailer B can still produce the lower total bill.
The right comparison uses your real data:
- Multiply each usage rate by the kWh in the matching time band.
- Apply the demand rate to the measured or billed demand basis.
- Add daily supply charges for the full term.
- Add metering, environmental and service lines.
- Apply contract escalation and pass-through rules.
- Check GST treatment and any exit cost from the current deal.
That is the same method behind our business electricity quote comparison checklist.
Network tariff and retail tariff are not the same thing
The words are similar, which causes plenty of confusion.
The network tariff is the distributor’s charging structure for the connection. It can be flat, time-based, demand-based or a combination.
The retail tariff or energy plan is the commercial offer from the retailer. It takes account of energy purchase costs, network inputs, fees, margins and contract conditions.
A retailer can offer a plan with time-of-use retail rates to a site that also has time-based network charges, but the time windows and calculations are not guaranteed to be identical. On a bundled small-business bill, the relationship may not be obvious from the front page.
Ask for the network tariff code and the retailer price fact sheet or contract schedule. Those two documents answer different questions and you need both for a proper review.
What about environmental and government charges?
These sit in a third bucket.
Federal schemes such as LRET and SRES create costs retailers must recover. Some states also have their own schemes. The underlying obligations are not removed by switching retailer, although a bill may show them as separate lines or bundle them into another rate.
They should not be confused with network charges, and they are not simply a retailer discount waiting to be negotiated away. Our guide to environmental charges on a business energy bill explains the national and state differences.
Multi-state businesses need to compare each site properly
A retailer can supply sites across several parts of the National Electricity Market, but each site remains attached to its local distributor and network tariff.
A Brisbane site, a Sydney site and a Melbourne site can sit under one commercial agreement while carrying different network inputs. That is normal. Forcing the bills into one identical line-by-line model can hide real differences in distribution area, tariff class and state charges.
For multi-site tenders, normalise the contestable retailer offer while preserving the correct network pass-through for each NMI. A portfolio total is useful, but site-level checks catch the tariff or demand problem that aggregation can hide.
A five-step bill check
- Find the distributor and network tariff. The bill or retailer should confirm both.
- Mark the network lines. Separate usage, fixed and demand-based network costs.
- Mark the retailer lines. Identify energy rates, supply charges, fees, margins and contract clauses.
- Separate government and environmental costs. Do not count them as a network or retailer saving without checking the contract treatment.
- Model the whole year. Use 12 months of usage and interval data where available, not one unusually hot or quiet bill.
If you send me the bill, I’ll mark the buckets and tell you where the realistic saving sits. Sometimes it is the retailer quote. Sometimes it is the tariff or demand profile. Sometimes the current account is already set up properly and the honest answer is to leave it alone.
