A family home uses a lot more power than a one-person flat. A household of four or more uses around 8,000 kWh of electricity a year, and every cent on the usage rate shows up on the bill. The good news is that the cheapest plans sit well below the official reference price, so switching can save a family hundreds of dollars a year.
Quick answer: On the Ausgrid network in Sydney, the cheapest single-rate plan right now is Tango Energy’s Everyday Easy, at an estimated $1,440 a year for a household using 3,900 kWh. But the best plan for your family depends on how much power you use, so always compare for your own postcode on the free government tool Energy Made Easy. All rates below were checked on 10 November 2026 and are for single-rate plans on the Ausgrid network, including GST. Rates differ by state and network, so treat them as a guide, not a quote.
What families should look for in an electricity plan
Families use more power, so the usage rate matters more than anything else. A plan that is 2c per kWh cheaper saves about $160 a year at 8,000 kWh. The daily supply charge matters too, but it is the same every day no matter how much you use, so it hurts smaller households more than big ones.
Look for these things when you compare:
- A low usage rate — this is where the real savings are for a big household.
- No lock-in contract or exit fee — so you can leave if a better deal appears.
- A decent solar feed-in tariff — if your home has solar panels, the rate you are paid for exported power adds up.
- Bill smoothing or monthly billing — spreading the cost helps when winter bills spike.
- A plan that suits your hours — if you can run the washing machine and dishwasher outside peak times, a time-of-use plan can be cheaper. Our guide to when off-peak electricity runs explains the cheapest hours in each state.
1. Tango Energy Everyday Easy
Best for: families who want the lowest bill overall.
Tango’s Everyday Easy is the cheapest single-rate plan on the Ausgrid network right now: 26.84c per kWh with a 107.8c a day supply charge, for an estimated $1,440 a year at 3,900 kWh. That is 24% below the reference price of $1,899 a year. There are no special conditions attached, and the plan has no lock-in contract, so it is an easy switch for a family that just wants the lowest rate.
2. 1st Energy 1st Emerald
Best for: very high-usage households.
1st Emerald has the lowest usage rate of any plan on the Ausgrid network: 26.4c per kWh. The trade-off is a higher daily supply charge of 132.88c a day, which pushes the estimated annual cost to $1,515 at 3,900 kWh. But for a family that uses a lot of power, the low usage rate wins out — the more you use, the better this plan looks. There is no lock-in contract.
3. Flipped Energy Anytime Switched On
Best for: a simple, cheap plan with no fuss.
Flipped’s Anytime Switched On plan charges 26.86c per kWh with a 114.45c a day supply charge, for an estimated $1,465 a year at 3,900 kWh — 23% below the reference price. It is a straightforward single-rate plan with no lock-in and no conditions to meet, which suits families who do not want to think about time-of-use tariffs or discount hoops.
4. Nectr Home Buzz
Best for: smaller families or households that use less than average.
Nectr’s Home Buzz charges 30.74c per kWh, which looks high next to the plans above, but its daily supply charge is only 82.91c a day — one of the lowest around. The estimated annual cost is $1,501 at 3,900 kWh, and Canstar lists it as the cheapest electricity plan in Sydney on its database as of 10 November 2026. If your family uses less power than average, the low supply charge makes this plan hard to beat.
5. Red Energy Living Energy Saver
Best for: families who want rewards and Australian-based support.
Red Energy’s Living Energy Saver charges 28.12c per kWh with a 134.75c a day supply charge, for an estimated $1,588 a year at 3,900 kWh. The plan earns Qantas Frequent Flyer points or Everyday Rewards points, and Red Energy won Canstar’s 2026 Most Satisfied Customers award for electricity providers in NSW. Its support team is based in Australia, which matters when you need to sort out a billing problem.
6. EnergyAustralia Total Plan
Best for: families who want price certainty for 12 months.
The Total Plan fixes your usage rates for 12 months, so your per-kWh price does not move when the market does. That certainty is worth a lot to a big household, where even a small rate rise adds up fast. There are no exit fees, so you can still leave if a better deal comes along, and monthly billing is available. Check the current fixed rate for your network before signing up, as it changes with each offer.
7. Origin Go Solar
Best for: family homes with rooftop solar panels.
If your home has solar, the feed-in tariff matters as much as the usage rate. Origin’s Go Solar plan pays up to 8c per kWh for the first 8 kWh you export each day in NSW, then 3c after that. Origin’s standard Go Variable plan charges 29.82c per kWh on the Ausgrid network. Families with solar should also ask about the Solar Sharer Offer, which gives three hours of free electricity in the middle of the day (up to 24 kWh a day) if you have a smart meter — you do not need your own panels for that one.
What a family actually pays at higher usage
The reference usage of 3,900 kWh a year suits a small household. A family of four or more typically uses around 8,000 kWh a year, and at that level the ranking still holds, but the gap changes. Using the rates above, Tango Everyday Easy works out to roughly $2,541 a year at 8,000 kWh, while 1st Energy 1st Emerald works out to roughly $2,597 — the low usage rate almost closes the gap, but Tango’s lower supply charge keeps it ahead. The lesson is simple: at family usage levels, compare the usage rate first and the supply charge second.
How to compare plans in five minutes
Start with the free government comparison tool for your state — Energy Made Easy for NSW, Queensland, South Australia, Tasmania and the ACT, or Victorian Energy Compare for Victoria. Enter your postcode and your last bill’s usage, and it will show real plans ranked by estimated annual cost. Compare each plan against the reference price for your network, check the benefit period and whether there is an exit fee, and re-check once a year. In Western Australia and the Northern Territory, prices are regulated and most households cannot choose their retailer, so comparison does not apply there.
Frequently asked questions
Can renters switch electricity providers?
Yes, as long as the electricity account is in your name and you pay the retailer directly rather than your landlord. No lock-in plans are the safest choice when you rent, because you can switch again when you move.
Is there one cheapest electricity provider for everyone?
No. The cheapest plan changes by network, tariff and how much power you use. A plan that is cheapest in Sydney can be mid-pack in Melbourne or Adelaide, which is why you should always compare for your own postcode.
Do I need solar panels to get a good deal?
No. The cheapest plans in this list work for any home. Solar helps if you have it, because a good feed-in tariff turns exported power into bill credits, but a low usage rate saves money with or without panels.
How often should a family compare electricity plans?
At least once a year, and whenever your benefit period ends or your retailer raises its rates. Retailers must tell you when a benefit period is ending, and that is the best moment to switch.
