When you are running a household on one income, every bill gets looked at twice. Groceries, school costs, petrol and rent or the mortgage all come first, and the power bill is usually the one that lands with a thud. If there is a pool in the backyard, there is a good chance a big chunk of that bill is coming from one place most of us never think about: the pool pump.
Ask most pool owners what their pump costs to run and they will guess a couple of hundred dollars a year. For an older pump the real figure is often closer to a thousand.
Why the pool pump costs so much
Most older pools have a single speed pump. It has one setting, flat out, whether it is doing a big clean or just quietly turning the water over on a Tuesday afternoon. A 1.5 horsepower single speed pump running seven hours a day, which is a normal summer setting in New South Wales, uses about 2,800 kilowatt hours a year. At current Sydney prices that is roughly $900 a year, or more than $220 a quarter, before you have turned on a light or the washing machine.
That is often more than the fridge, the dryer and the TV put together. In a lot of homes it is the single biggest thing on the bill after heating and cooling.
What a $700 a year saving looks like
A newer variable speed pump does the same job very differently. It runs slowly for most of the day and only speeds up when the pool actually needs it. Because the power a pump uses drops away sharply as it slows down, running at half speed uses roughly an eighth of the power. The same pool that cost about $900 a year to run costs around $190 with a 6 star variable speed pump on a sensible schedule.
For a single parent budget, a saving of around $700 a year is real money. It is:
- roughly $58 a month back in your pocket, every month
- a term of swimming lessons, or most of a year of school excursions
- a quarterly power bill that is around $175 smaller
Savings usually land between $500 and $1,100 a year depending on the size of the pool and how long the old pump was set to run. The new pumps are also much quieter, which you notice straight away if a bedroom sits near the pool.
The cost of switching, and the rebate that covers most of it
The catch has always been the up front price. A good variable speed pump costs $990 to $1,890 to buy, and pool shops typically charge $1,500 to $2,500 installed. When you are watching every dollar, that is a hard number to find, even when you know it pays off.
What many NSW families do not know is that the state's Energy Savings Scheme now covers a large part of that cost when an old single speed pump is replaced by an accredited provider. It is not a form you fill in and wait for a cheque. The discount comes straight off the installed price, so you only ever pay the reduced amount. Done through an accredited installer, a pool pump replacement with a 6 star 2.0 horsepower variable speed pump comes to $899 installed across Sydney, the Central Coast, Newcastle, the Hunter and the South Coast. That includes the pump, installation, setting it up for your pool and taking the old pump away.
At $899 against a saving of around $700 a year, the pump pays for itself in about 15 months. After that, the saving is yours for the ten or more years the pump keeps running.
Who can get it
- You live in NSW and you are replacing an existing pool pump. A brand new pool's first pump does not qualify.
- If you own your home, you can go ahead directly.
- If you rent, the owner needs to agree. It is worth asking: the pump belongs to the property, and a landlord who pays for the pool equipment may well be happy to replace it at this price.
- Eligibility is checked before anyone comes out, usually from three photos of your current pump and a recent power bill. The bill is only used for the meter number and address.
Some councils add their own rebate on top. Randwick refunds 50 per cent up to $250 on pumps installed in the previous 12 months, and Ku-ring-gai pays $250 on pumps bought after 1 July 2026 with pre approval. Those are claimed from the council after the install.
Is your pump the problem? Three quick checks
- Age. If the pump is more than eight years old, it is almost certainly single speed.
- Your bills. If your summer power bills jump by $200 to $300 a quarter compared with winter and nothing else has changed, the pump is the likely cause.
- Noise. If you can hear it clearly from inside the house, it is running flat out.
If two of those sound familiar, the swap is close to free money. And if the old pump has started tripping the power or leaking, a repair call out at $80 to $150 is money better put towards the replacement.
Free things you can do today
Even before changing the pump, check the timer. Many are still set to the builder's settings from years ago, running eight or ten hours a day in winter as well as summer. Cutting winter run time to match the cooler months costs nothing. Keep the pump basket and filter clean too, because a blocked filter makes the pump work harder for every hour it runs.
Pool season starts in earnest in late October. Swap the pump before the first heatwave and the first summer's saving does most of the paying. The full steps and current pricing are on Efficient Energy Group's pool pump page.
