What's the easiest way to cut my electricity bill in 2025-26?

Switch retailers. Households on a standing offer typically save $300–$600 a year by moving to the cheapest market offer for their postcode using Energy Made Easy or Victorian Energy Compare. Re-check at least twice a year because discounts move quietly.

Should I be on a flat rate or a time-of-use plan?

It depends on when you use power. Households mostly active in the evening with no load-shifting options usually do better on a flat rate. Households with rooftop solar, an EV or the ability to shift heavy appliances away from the 4–9 pm peak almost always do better on a time-of-use plan.

Is a heat-pump hot water system worth it?

For most Australian households on a fully-electric or electrifying setup, yes. Heat-pump hot-water systems use roughly a third of the energy of a traditional electric storage system and are heavily rebated in NSW, Victoria and the ACT. Running cost savings typically run $300–$500 a year for a four-person household.

How much does rooftop solar reduce a typical bill?

A 6.6 kW system on an average suburban roof, with 30% self-consumption, saves $1,000–$1,400 a year for a typical 20 kWh/day household. With 60% self-consumption (a battery, EV or daytime hot-water timer), savings rise to $1,700–$2,000 a year. Use the Wattcalc solar payback calculator to model your own numbers.

Is it cheaper to electrify gas appliances?

Over the medium term, yes for most households. Heat-pump hot water, induction cooking and reverse-cycle heating typically cut combined energy bills by 30–50% in southern Australia compared with gas equivalents. Daily gas supply charges are also rising as gas-network customer numbers fall, which compounds the savings.

Reduce your electricity bill in Australia (2025–26)

From the easiest five-minute switch to the bigger structural moves, here are the highest-impact ways to cut a typical Australian electricity bill in 2025–26 — ranked by likely dollar saving.

Australian household electricity bills have ratcheted up across the past three years. The Default Market Offer published by the Australian Energy Regulator rose by double digits in many states, and most retailers have followed. The good news: the highest-impact moves a household can make in 2025–26 are also the cheapest and easiest. This guide ranks them by likely dollar impact for a typical 20 kWh/day household.

1. Switch retailers — and check the offer twice a year

The biggest single saving most Australian households can make today is moving from a "standing offer" to the cheapest market offer for their postcode. The federal Energy Made Easy tool (and the equivalent in Victoria, Victorian Energy Compare) lets you upload a recent bill and rank every available plan in your area.

Households on a standing offer typically save $300–$600 per year by switching to a competitive market offer. Re-check at least twice a year — discounts and conditional rebates change quietly.

2. Match your tariff structure to your usage

Most Australian households are on either a flat rate (one rate all day) or a time-of-use (TOU) plan with peak/shoulder/off-peak rates. The right structure depends on when you use power:

Mostly evenings, with peaks 4–9 pm: a flat rate is usually cheaper unless you can shift load.
EV owner, hot-water on a controlled-load circuit, or daytime user with solar: TOU often wins, especially if you can shift the dishwasher, washing machine and EV charging into off-peak.
Solar with high export: some retailers offer solar-specific plans with higher feed-in tariffs but slightly higher retail rates — the maths depends on your self-consumption.

Energy Made Easy now lets you upload a smart-meter download to see which structure would have been cheapest given your last 12 months of usage.

3. Shift heavy loads off the evening peak

The evening peak (4–9 pm) is the most expensive period on every TOU plan and the most stressed period on the grid. Two appliances dominate it for most households: the air-conditioner and the dryer.

Pre-cool or pre-heat the home in the late afternoon (3–4 pm) and rely on insulation through the peak.
Run the dryer overnight on a TOU plan — or hang the load if at all possible.
Run the dishwasher and washing machine after 9 pm or on a delay timer.
Set the electric hot-water service to heat between 11 am and 2 pm if you have rooftop solar — controlled-load tariffs traditionally heat overnight, but daytime heating uses the cheapest power for solar households.

For a household using 4–6 kWh of evening peak power, shifting half of it to off-peak typically saves $150–$300/year on a TOU plan.

4. Replace the worst appliances first

Standby and old appliances quietly add up. The two highest-impact replacements in most Australian homes:

An old second fridge in the garage — often a 20–30 year old unit drawing 600–900 kWh/year. Removing it (or replacing with an Energy Star equivalent) can save $200–$300/year.
An ageing electric storage hot-water system — typically the single biggest line item on a household bill. A heat-pump hot-water system uses roughly one third of the power and is heavily rebated in many states.

The federal Energy Rating site at energyrating.gov.au publishes star ratings and estimated annual running costs for every regulated category — worth checking before you replace anything.

5. Electrify gas appliances (eventually)

Gas networks are shrinking. In Victoria and the ACT, new gas connections are now restricted, and most major retailers warn that residual customers will face rising daily supply charges as customer numbers fall. For most households, the cheapest long-term path is to electrify gradually:

Replace gas hot water with a heat-pump unit at end of life.
Replace gas cooking with an induction cooktop at the next kitchen refresh.
Replace ducted gas heating with a reverse-cycle split-system at end of life.

The Renew Magazine household electrification calculator publishes detailed running-cost comparisons by climate zone — typically showing a 30–50% reduction in combined energy bills after full electrification.

6. Add solar (and use what it generates)

For households with reasonable daytime usage, rooftop solar remains the largest available bill reduction. A 6.6 kW system on an average suburban roof typically delivers $1,000–$1,800 of annual savings depending on self-consumption — usually paying back the system in 5–8 years. Run your own numbers in the solar payback calculator.

The single highest-impact lever is self-consumption. Every kWh you use in your house saves you the retail rate (28–35 c/kWh). Every kWh you export earns the feed-in tariff (4–7 c/kWh). Hot-water timers, daytime washing and EV charging all push self-consumption up.

7. Charge an EV cheaply at home

If you drive an EV, your electricity bill becomes part of your transport budget. Three rates matter:

Off-peak overnight: 18–25 c/kWh on most TOU plans.
Solar self-charging: effectively 4–7 c/kWh (the feed-in tariff you would otherwise have earned).
Public DC fast charging: 35–70 c/kWh — useful occasionally, expensive for daily use.

Charging mostly off-peak or from solar can cut EV running costs by 30–50% versus charging at a flat retail rate. The EV vs petrol calculator lets you model the difference.

What to do this week

Upload your most recent bill to Energy Made Easy (or Victorian Energy Compare) and switch if a cheaper plan exists.
Set your hot-water service or controlled-load to whichever block of hours your tariff and household usage suits best.
Audit appliances over 15 years old — fridges, hot-water systems and dryers are the usual culprits.
If you're a daytime household with a north or east/west roof, get three solar quotes and run the maths in the solar payback calculator.
