But this convenience, this reclaiming of commute time, hasn’t come without a cost. The battleground for many household budgets hasn’t disappeared; it’s simply shifted from the train platform or the petrol pump to the energy bill landing in your inbox and the cost of keeping a functional workspace running. Working from home isn’t ‘free’. It’s a complex financial equation, a redistribution of expenses from the employer and the daily grind onto the home front. For some, the sums add up favourably; for others, the hidden costs are starting to bite. Understanding this new equation is crucial for managing your finances in 2025.

It’s easy to focus on the savings – the train fares dodged, the expensive city lunches skipped. But the costs lurking within your own four walls need a proper accounting. They creep up quietly, often disguised as regular household expenses, until the quarterly bills land with a thud.
Keeping the Lights On (and the Laptop Charged)
The most obvious hit? Energy bills. Having the house occupied all day, running computers, monitors, extra lighting, and crucially, heating or cooling, inevitably pushes up consumption. The numbers paint a clear picture. As of April 2025, average quarterly electricity bills vary significantly across the states, reflecting different climates and network costs. Finder.com.au data shows New South Wales residents facing the highest average quarterly bills at around $444, with South Australians not far behind at $375. Victorians average $339, Queenslanders $370, while Western Australians enjoy the lowest average at $254.
Looking closer at Sydney, estimates suggest a two-person household might see a monthly electricity bill around $92, rising to $139 for a four-person household. These figures are based on average daily usage, which naturally climbs when someone’s home all day. Typical usage rates in Sydney hover around 30 to 38 cents per kilowatt-hour (kWh), plus daily supply charges that vary between providers like AGL, EnergyAustralia, or Dodo.
Why the jump? Consider the tools of the trade. A standard desktop computer and monitor can chew through 0.06 to 0.3 kWh every hour they’re running. Even an energy-sipping laptop uses around 0.06 kWh per hour. Run that desktop for a standard eight-hour workday, five days a week, and you could be adding anywhere from $50 to over $240 to your annual electricity bill, just for that one machine, depending on its efficiency and your local tariff. Add in extra lighting, more frequent boiling of the kettle, and the big one – climate control – and the costs multiply.
This shift introduces a nasty volatility into household budgeting. Office energy costs are smoothed out, part of a building’s overall operational expense. At home, your bill directly reflects your usage, heavily influenced by the season. A heatwave or a cold snap sends costs soaring when you’re relying on home air conditioning or heating all day, rather than the office system. This makes forecasting monthly expenses far more challengin
