If you’re renting or buying an apartment in Australia, the monthly rent or mortgage is only part of the picture. Utility bills—electricity, gas, water, and internet—can add up to hundreds of dollars a month, and the way they’re charged in an apartment block is often different from a standalone house. Understanding these costs before you sign a lease or contract can save you from some unpleasant surprises.

Electricity and gas prices rose an average of 8% across major cities in 2026, driven by wholesale market volatility and network upgrades passed on to consumers. Water prices climbed 4–6% in most metro areas due to scarcity. For apartment dwellers, the structure of these bills—especially embedded networks and strata-metered water—can mean your costs look different from what you’d pay in a house. Here’s what you actually need to know.
Before we go further, let’s clarify one term you’ll see a lot. An embedded network is a private electricity network that supplies power to multiple apartments within a single building or complex. Instead of each apartment having its own direct connection to the main grid, the building buys electricity in bulk and on-sells it to residents. This setup has historically led to higher prices, but new NSW regulations from July 2026 now cap what embedded network operators can charge.
What I tend to notice is that people moving into apartments for the first time don’t realise how much the building’s setup affects their bills. It’s worth checking whether your apartment is part of an embedded network before you sign anything.
What your apartment utility bills actually look like
The headline figure—your monthly electricity bill—is only one layer. For a 2-person apartment in Sydney, the total utility picture includes electricity, internet, transport, and water usage, adding up to roughly $513 per month. But that number shifts depending on where you live and how your building is set up.
Electricity is the standout cost. The typical annual bill ranges from $1,400 to $2,300, with Sydney averaging around $1,801 per year and Melbourne closer to $1,465. Gas adds another layer: the average Sydney household spends about $1,270 per year on gas, though new apartment builds in the City of Sydney now ban gas connections entirely. If you’re in a newer apartment, you may not have a gas bill at all.
Water is where apartment living gets tricky. If your apartment has a separate water meter and the building holds a Water Efficiency Certificate, you’ll only pay for the water you use—roughly $40 per month for a 2-person household. Without that certificate, the landlord can bill you based on a share of the building’s total water usage, which can be higher. The fixed service charges for water in Sydney run about $233.20 per quarter, covering wastewater, water service, and stormwater, but those are typically the landlord’s responsibility in rental properties.

| Utility | Typical Monthly Cost (2-person Sydney apartment) | Key Variables |
|---|---|---|
| Electricity | $188 | Supply charge ($0.92–$1.15/day) + usage ($0.28–$0.38/kWh); market offers ~10% cheaper |
| Internet (NBN 50) | $85 | Introductory rates as low as $55–$65 for first 6 months |
| Transport | $200 | Opal weekly cap $50; airport access fee $17.92 |
| Water usage (tenant) | $40 | Only if separately metered and Water Efficiency Certificate held |
Internet is a fixed cost you can control. NBN 50 plans run $85–$93 per month, with introductory rates as low as $55–$65 for the first six months. Transport costs depend on how often you use public transport, but the Opal weekly cap of $50 keeps a lid on it. The airport access fee of $17.92 is worth noting if you travel frequently.
Common mistakes apartment residents make with utilities
Assuming your building’s electricity setup is the same as a house
Many apartment residents don’t realise they’re in an embedded network until they try to switch providers. In an embedded network, you can’t choose your own retailer—the building operator is your only option. This can lock you into higher rates. From July 2026, new NSW legislation caps embedded network prices, but if you’re in an older building or another state, you may be stuck paying more. Before you move in, ask the landlord or strata manager whether the building has an embedded network and what the current rate is.
Paying for water you didn’t use
If your apartment doesn’t have a separate water meter, or the building lacks a Water Efficiency Certificate, you could be billed based on a share of the entire building’s water usage. That means you’re paying for common area watering, leaks, and your neighbour’s long showers. In NSW, tenants are only required to pay for water usage if the apartment is separately metered and the building holds a Water Efficiency Certificate. If either condition isn’t met, the landlord covers the water bill. Check your lease and ask the agent before you move in.
Sticking with a standing offer instead of a market offer
Standing offers are the default electricity plans that retailers offer when you don’t actively choose a plan. They’re typically $200–$400 more per year than market offers. In apartments, especially embedded networks, you may not have a choice of retailer, but if you’re on a standard connection, using the AER Energy Made Easy tool to compare plans can save you over $300 per year. The Smith family in Adelaide cut their combined energy and water bills by 28% just by switching retailers and installing a $99 smart thermostat.
Overlooking rebates and concessions you’re entitled to
The federal Energy Bill Relief Fund provides up to $350 in credits for eligible households in 2026, including Centrelink recipients and concession card holders. Victoria offers an additional 15% gas bill discount through the Winter Gas Concession until September 2026. Water efficiency rebates of up to $200 are available in many states for installing water-efficient appliances. These aren’t automatic—you usually need to apply through your state government’s energy or water website. Missing them means leaving money on the table.
How to manage and reduce your apartment utility costs
Understand your building’s utility setup before you move in
This is the single most important step. Ask the landlord or strata manager: Is the apartment on an embedded network? Is there a separate water meter? Does the building hold a Water Efficiency Certificate? Is gas connected, or is the building all-electric? The answers determine which bills you’ll receive and whether you can switch providers. For a deeper look at how strata fees interact with utility costs, see our guide on strata fees in Australian apartments.
Compare and switch electricity plans every 12 months
If you’re not in an embedded network, use the AER Energy Made Easy website to compare plans. Market offers are roughly 10% cheaper than standing offers, and many providers offer introductory rates for the first 6–12 months. Set a calendar reminder to review your plan annually. The process takes about 15 minutes and can save you $200–$400 per year.
Use smart technology to monitor and reduce usage
Smart thermostats, real-time usage apps, and Wi‑Fi-enabled power strips can help you track and cut your electricity consumption. The Johnson family in Brisbane replaced an old fridge and installed a 5kW solar panel system with a Queensland rebate, cutting their electricity bills by 40%. Even without solar, simple changes like switching to LED bulbs and using a programmable thermostat can reduce your usage by 10–15%.
Apply for rebates and concessions
Check your eligibility for the Energy Bill Relief Fund (up to $350), state-specific concessions like Victoria’s Winter Gas Concession (15% discount), and water efficiency rebates (up to $200). Each program has its own application process, usually through your state government’s energy or water website. Keep copies of your concession cards and recent bills handy.
Plan for future policy changes
From July 2026, NSW caps embedded network prices. The City of Sydney has banned gas connections in new builds, which means newer apartments will be all-electric—potentially lowering your gas bill to zero but increasing your electricity usage. Dynamic pricing with smart meters is becoming more common, with off-peak EV tariffs offering cheaper rates for overnight charging. These changes will shift how you manage your energy costs over the next few years.

Utility costs are part of the apartment decision, not an afterthought
The difference between a well-managed apartment utility setup and a poorly structured one can be hundreds of dollars a year. Embedded network caps in NSW, gas bans in new builds, and rising water prices all point in one direction: the building’s infrastructure matters as much as the location or the view. Before you commit to a lease or purchase, ask the hard questions about metering, certificates, and network type. That five-minute conversation could save you a lot more than five minutes of hassle later.
