NSW Embedded Network Billing Rules: What Landlords Need To Know
Embedded networks are common in apartment buildings, retirement villages and other multi occupancy properties where electricity reaches residents through a private network rather than directly from a retailer. For landlords, owners and property managers in NSW, the rules governing those arrangements are tightening.
The reforms are being introduced in stages. The first stage brought new obligations for embedded network sellers around dispute resolution and public disclosure. A second stage covering maximum prices and a residential billing standard is still to come. That gap between stages is the useful part, because it gives property owners time to fix the underlying metering before the pricing rules bite.
Understanding what is coming now can prevent a rushed and expensive scramble later.
Key Points
- NSW embedded network sellers face new obligations covering ombudsman membership and public disclosure of prices, premises and service types.
- IPART holds the compliance role for the NSW scheme while EWON provides independent dispute resolution for residents.
- A residential billing standard and a maximum price methodology are still to commence, so bills will need to show how charges compare with the permitted ceiling.
- These state obligations sit on top of existing AER retail and network exemptions rather than replacing them.
- Billing accuracy depends on meters that are approved for trade use and correctly identified against the right tenancy.
- SATEC supplies NMI approved submetering hardware and Expertpower software so consumption data can be traced from the meter through to the resident’s bill.
What Has Changed So Far
The first stage focused on accountability. Embedded network sellers that were not already members of the Energy and Water Ombudsman NSW (EWON) must join the scheme, which gives residents somewhere independent to take a complaint.
Sellers must also publish information about the services they provide. That covers current prices, the premises where those services are supplied and the type of embedded network service at each location. Many landlords have treated electricity on charging as a quiet administrative function sitting inside the body corporate budget. Publishing your prices changes that. It invites comparison and it invites questions.
IPART holds the compliance and enforcement role for these requirements.
Billing Rules Are The Next Major Change
IPART has been developing a billing standard for residential embedded network customers alongside a methodology for setting maximum prices. Both are still working through the approval process.
The draft approach is designed to make bills clearer. Residents would be able to see the maximum price permitted for their supply and compare it against what they are actually being charged. A seller could charge less than the ceiling but never more.
For landlords the consequence is straightforward. Every figure on that bill will need to be explainable. If a resident asks how a charge was calculated, the answer needs to trace back through a tariff, a consumption figure and a meter reading without any hand waving in the middle.
Accurate Meter Data Becomes The Evidence
Billing disputes rarely begin with the tariff. In our experience they begin with a resident who cannot see how a number was reached, and they escalate when nobody can produce the reading history behind it.
The practical weak point in most embedded networks is not meter accuracy. It is meter identification. A meter that is accurate to 0.5 per cent is worthless if it has been mapped to the wrong apartment, and that kind of error can sit undetected for years until someone finally compares their bill to their neighbour’s.
Electricity meters used to sell power to tenants must be approved for trade use under the National Measurement Institute framework. That makes meter selection part of the billing process rather than a purchasing decision made by whoever fitted out the switchboard.
Manual reading and spreadsheet billing hold together at ten apartments. They rarely hold together at eighty. A single missed reading or a transposed meter number can turn into a dispute that costs far more to resolve than the metering upgrade would have cost to install.
Comparing Metering And Billing Setups
Not every embedded network needs the same solution. The table below sets out how three common setups perform against the direction the NSW rules are heading.
| Setup | Meter Basis | Data Collection | Evidence In A Dispute | Fit With The NSW Reforms |
|---|---|---|---|---|
| Manual reading with spreadsheet billing | Often mixed or unapproved legacy meters | Site visits and manual entry | Weak, relies on handwritten records | Poor, difficult to demonstrate accuracy or produce history |
| Approved submeters read on site | NMI approved meters | Local download or walk by reading | Moderate, readings exist but gaps are common | Workable, though slow to audit and prone to entry error |
| NMI approved submetering with remote data and billing software | NMI approved meters correctly mapped to tenancies | Automated remote collection at interval level | Strong, full reading history and calculation trail | Well placed, adapts to tariff changes and price ceilings |
What Landlords Should Review Now
There is still time to prepare. Leaving the work until the final commencement date means changing meters, software and billing processes all at once, which is the most expensive way to do it.
A practical review covers four areas:
- Confirm who is legally acting as the embedded network seller at each property and check that the relevant AER exemptions are current.
- Review ombudsman membership and website disclosure against the NSW requirements.
- Check that meters used for tenant billing are approved for trade use and correctly identified against the right tenancy.
- Review billing software, tariff structures and data collection so you know how quickly they could adapt to a maximum price and a mandated bill format.
The goal is a clear and defensible path from measured consumption to the amount printed on the bill.
The Metering Foundation From SATEC
Embedded network billing rests on measurement that survives scrutiny. With over 50-plus years experience, SATEC has built metering for exactly that purpose.
The EM133-XM is an NMI approved DIN rail energy meter designed for Australian submetering and billing. Its compact format suits apartment switchboards where space is limited and retrofit work has to fit around existing equipment. Class 0.5S accuracy and remote communications mean readings arrive without anyone visiting the site.
Where a building needs many circuits measured in one location, the BFM136 provides NMI approved multi circuit metering. That reduces switchboard space on larger sites while still delivering individual circuit consumption data.
Expertpower brings that meter data into a central platform for monitoring, reporting and billing. Tariff configuration, cost calculation, subtenant consumption tracking and invoicing all sit in one place, which removes the spreadsheet step where most billing errors are introduced.
Residents can also be given visibility of their own consumption through the eXpertConnect app. This applies where individual submeters are connected to Expertpower and the resident is an approved user. Residents see their own energy usage only. Common area consumption is not accessible through the app.
No meter or software platform amounts to automatic compliance, and the final NSW billing standard is still being settled. Building on approved metering and accessible interval data simply puts a billing system in a far better position to adapt when the remaining requirements commence.
Preparing Now Prevents Problems Later
The NSW reforms are pushing embedded networks towards price transparency, clearer bills and real accountability. That puts pressure on how consumption is measured as much as how charges are calculated.
The task for landlords and property managers is not to wait for the next deadline. It is to find the gaps in metering, data collection and customer communication while there is still time to fix them calmly.
Properties with accurate metering and structured billing will absorb the new rules without drama. Properties running on manual readings and legacy meters will not.

FAQs - NSW Embedded Network Billing Rules
-
Do I need to be an EWON member if I run an embedded network in NSW?
Under the NSW reforms, embedded network sellers that were not already members must join the Energy and Water Ombudsman NSW scheme. This gives residents access to independent dispute resolution. Check your current status against the IPART guidance for your property type.
-
Can I charge residents whatever tariff I choose?
Not once the maximum price methodology commences. IPART is setting a ceiling that sellers cannot exceed, though charging below it remains permitted. Your billing system will need to show how your price compares with that ceiling.
-
Do apartment submeters need to be NMI approved?
Yes, where the meter is used to sell electricity to a tenant or resident. Meters used for trade must hold pattern approval under the National Measurement Institute framework. Using an unapproved meter for billing exposes you to compliance risk and makes disputes far harder to defend.
-
What happens if a resident disputes their bill?
You need to produce the meter reading history and show how the charge was calculated from it. Systems built on remote interval data can answer that question in minutes. Manual reading and spreadsheet billing often cannot answer it at all.
