Winter Energy Bill Has Arrived. It is the best time to compare energy providers

Winter is when many Australian households receive some of their highest electricity bills of the year. With heaters, hot water systems and longer nights driving up energy use, it's also the time when thousands of Australians start to compare energy providers.

If your latest bill was higher than expected, it could be worth checking whether you're still on the right plan.

In this article we'll cover why winter bills increase, what to look for when you compare energy providers, how switching could help you reduce your electricity bill, simple ways to cut your winter energy costs, and why now is the ideal time to review your plan.

Why winter bills increase

Most of the jump is simply usage. Heating is the single biggest driver, hot water works harder when it's cold, and longer, darker evenings mean lights and appliances run more.

But it's not only what happens inside your home. Wholesale energy costs tend to climb in winter as demand across the grid peaks, and network and supply charges have been rising too, so the rate you pay can be higher at the very time you're using the most.

Summer is almost the mirror image. Your rooftop solar produces more, days are longer, and a stronger feed in tariff return plus lower heating needs mean your home simply costs less to run, which is why summer bills usually land lower.

None of that means you're on a bad plan. But a higher winter bill is the moment most people finally look under the hood, and the fastest way to reduce your electricity bill is to check you're on the right one.

What to look for when you compare energy providers

When you compare energy providers, don't just glance at the headline rate. Three numbers tell the real story: the daily supply charge, the usage rate per kWh, and, if you have solar, the feed in tariff.

Check whether any introductory discount is about to expire, a plan that looked cheap last year can quietly become expensive once the discount rolls off.

The fairest way to compare energy providers is against the government reference price. In NSW and South East Queensland that's the Default Market Offer, in Victoria the Victorian Default Offer. If you're sitting well above it, there's likely a better deal out there.

How switching could help you save

Switching is faster and simpler than most people expect. There's no interruption to your power, no need for anyone to visit, and in most cases no exit fees on market plans.

All it usually takes is a recent bill and a few minutes. Here's the quick version:

• Grab your latest bill and note your daily supply charge, your usage rate, and your plan type (flat or time of use).
• Check how your rate compares to the reference price printed on the bill.
• Compare a competitive plan against it, then switch online or over the phone.

Moving off an old or default plan and onto a competitive one is one of the quickest ways to reduce your electricity bill when it spikes in winter.

Simple ways to cut your winter energy costs

A better plan does the heavy lifting, but a few habits help too. Heating a little cooler and sealing draughts makes a real dent, since heating is your biggest winter cost.

If you're on a time of use plan, timing matters as much as the habit itself. The evening peak, roughly 3pm to 9pm, is the most expensive window, and it lands right when you get home and crank the heater. A few simple shifts help:

• Run the dishwasher, washing machine and dryer outside the evening peak, either overnight in the off-peak window or in the middle of the day.
• If you have solar with a decent feed in tariff, use heavy appliances while the sun is up, so you're using your own power instead of exporting it cheaply.
• Charge an EV overnight on off-peak rates, not the moment you get home in peak.
• Pre-heat the house before the peak starts, then let it coast, rather than running the heater hard through the most expensive hours.

Shifting usage like this moves it to cheaper rates and helps reduce your power bill. And make sure any concessions or rebates you're entitled to are actually applied, because these often go unclaimed.

Why now is the ideal time to review your energy plan

Prices reset on 1 July each year, and for 2026 many benchmarks moved lower across the eastern states. That means the plans available today may look quite different from the one you signed up to.

A winter bill spike plus a fresh set of offers is the ideal moment to compare energy providers. A few minutes now could reduce your electricity bill for the rest of the year, not just this quarter.
