Pool Running Costs Per Year Australia

Name: comparepoolquotes
Price range: $$$

Running a backyard pool in Australia costs roughly $1,200–$2,500 a year. The filtration pump is the small part, about $96–$216 a year for an efficient unit at 33c/kWh. Chemicals ($360–$1,200) and heating (up to $1,500 for a six-month gas season) dominate. Published estimates disagree, so budget on the range rather than a single price.

The short answer

Total $1,200–$2,500 a year for a standard backyard pool, on an assumed 33c/kWh — the Australian Energy Regulator's benchmark default market offer for July 2026.
The pump is not the villain: an efficient unit costs about $96–$216 a year. A 6-star pump uses 657 kWh a year, a 9-star just 305 kWh.
Heating is the swing factor. Over a six-month season: roughly $96–$240 on solar, $300–$1,020 on a heat pump, $600–$1,500 on gas.
Chemicals and cleaning run $360–$1,200+ a year; water top-ups and general maintenance another $360–$720.
A pool cover cuts evaporation by 90–95%, saving around 3,000 litres a month — plus the chemicals and heat that went with that water.

Where the money goes each year, at 33c/kWh
Cost	Per month	Per year	What moves it
Filtration pump	$8–$18	$96–$216	Star rating and run hours — a 6-star pump uses 657 kWh a year, a 9-star 305 kWh
Heating — solar	$16–$40	$96–$240 over a six-month season	Roof area and sun. The cheapest heat available
Heating — heat pump	$50–$170	$300–$1,020 over a six-month season	Ambient temperature, and whether you cover the pool overnight
Heating — gas	$100–$250	$600–$1,500 over a six-month season	Fast to heat, expensive to hold
Chemicals and cleaning	$30–$100+	$360–$1,200+	Sun, rain, bather load, and whether the pool is covered
Water top-ups and maintenance	$30–$60	$360–$720	Evaporation — around 7mm a day, uncovered, through summer
Typical total	$100–$200	$1,200–$2,500	Heating is the difference between the two ends of that range

The pump costs less than its reputation, but the sources disagree

Ask around and you will be told the pool pump is the reason your electricity bill went up. The published numbers do not agree on how true that is, and the disagreement is worth understanding rather than papering over.

Working from an itemised breakdown at 33c/kWh, an efficient filtration pump costs about $8–$18 a month, or $96–$216 a year. A comparison of two labelled models makes the mechanism clear: a 6-star pump draws 657 kWh a year while a 9-star draws 305 kWh, roughly half. Another consumer estimate puts a pump at 16c to 51c an hour depending on pool size, which lands in a similar place for a modest pump and a lot higher for a large single-speed one.

Against that, Sustainability Victoria's guidance states that pool pumps can add up to 20 or 30% of your energy bill — a much bigger claim. Both can be true of different households: an oversized single-speed pump running eight hours a day on a big pool is a completely different animal from a modern variable-speed unit filtering a plunge pool. The lesson is not to trust any single figure, but to check the star rating on your own pump and the hours it actually runs.

Note the vintage, too. The Sustainability Victoria page was last updated in December 2020 and the agency itself closed on 30 June 2026, so treat it as background rather than current advice.

Heating is the line that decides your annual bill

Everything else on the list is fairly stable. Heating is what separates a $1,200 pool from a $2,500 one.

Solar is the cheapest to run by a wide margin — roughly $16–$40 a month, or $96–$240 across a six-month season. It has no fuel cost; you are paying to circulate water through roof collectors. The catch is that it heats when the sun is out and not otherwise, so it extends the season rather than guaranteeing a temperature.

Heat pumps sit in the middle at about $50–$170 a month, $300–$1,020 for a season. They move heat rather than making it, which makes them efficient, and less efficient as the air gets colder — which is exactly when you want them.

Gas is the most expensive to run at $100–$250 a month, $600–$1,500 a season, but it heats fast. It suits people who want the pool warm this weekend rather than warm all summer.

If you heat at all, a cover stops being optional. Heat leaves a pool mostly through the surface, and covering it overnight is the difference between holding the temperature you paid for and buying it again tomorrow.

Chemicals, and why a cover changes them

Chemicals and cleaning are budgeted at roughly $30–$100 or more a month, $360–$1,200+ a year. The spread is wide because chemical demand is driven by things you do not control: hours of direct sun on the water, rain and debris, how many people swim and how often.

Salt chlorinated pools are not chemical-free, and the running cost difference between salt and manually dosed chlorine is smaller than the marketing suggests — you are trading bags of salt and cell replacement against drums of liquid chlorine. The bigger lever is sunlight: ultraviolet light destroys free chlorine, so a covered pool holds its sanitiser longer and needs less of it.

Servicing is the other variable. Doing it yourself costs time and test kits; a regular service visit is a real line item that we have not costed here because rates differ too much by region and frequency to publish a number we can stand behind.

Water: 7mm a day, and what that adds up to

An uncovered backyard pool loses around 7mm of water a day through the summer months. On a typical pool that is thousands of litres a month walking off into the air, and every litre you replace arrives at mains water prices with chemicals to follow it.

A pool cover reduces evaporation by 90–95%, saving in the order of 3,000 litres a month. It is the single highest-return purchase in this entire article, because the same sheet of plastic cuts water loss, heat loss and chemical demand at once.

Worth checking separately: a leak. A drip of one drop per second adds up to about 7,000 litres a year, and it is easy to mistake for evaporation. If your top-up demand does not fall when you start covering the pool, you have a leak rather than an evaporation problem.

Fibreglass or concrete: does the shell change the bill?

This comes up constantly and deserves an honest answer: we could not verify a credible Australian figure for the running-cost difference between a fibreglass and a concrete pool of the same size, so we are not going to publish one.

What can be said is directional. The variables that dominate your bill — volume of water, surface area, hours of sun, how you heat it and whether you cover it — are properties of the pool's size and how you use it, not of what the shell is made from. Interior surface has some effect on chemical demand and cleaning effort, but it is a second-order factor next to heating.

If running cost is your priority, choose a smaller pool, a high-star variable-speed pump and a cover, in that order. The shell material is a decision about budget, build time, shape and access.

What actually lowers the bill

Buy the cover first. Evaporation, heat and chemicals all drop together. Nothing else on this list does three jobs.

Check your pump's star rating. Each additional star on the label represents around 20% less energy. The gap between a 6-star and a 9-star unit was 352 kWh a year in the comparison above — on 33c/kWh that is roughly $116 a year, every year, for a decision you make once.

Run it for the right length of time. The guidance is to turn the whole volume of the pool through the filter once or twice a day. Many pumps are simply left running longer than that out of habit.

Shift the hours. If you are on a time-of-use tariff or have rooftop solar, filtering in the middle of the day rather than the evening peak changes the price of the same kilowatt-hours.

Heat deliberately. Heating an uncovered pool is the most expensive thing you can do with a pool. Heating a covered one is reasonable.

Common questions

How much does a pool cost to run per year in Australia?

Roughly $1,200–$2,500 a year for a standard backyard pool, or about $100–$200 a month, according to Finder's 2026 breakdown, which assumes 33c/kWh based on the Australian Energy Regulator's benchmark default market offer for July 2026. Heating decides where in that range you land.

Is a pool pump expensive to run?

The sources disagree. Itemised estimates put an efficient pump at $96–$216 a year, while Sustainability Victoria says pool pumps can add up to 20 or 30% of an energy bill. Both are plausible for different pumps: an oversized single-speed unit running long hours is a different case from a high-star variable-speed one. That page was last updated in 2020 and the agency closed on 30 June 2026.

Does a pool cover really save money?

Yes, and it is the clearest saving available. SPASA reports that a cover reduces evaporation by 90–95%, saving about 3,000 litres a month, and the same barrier holds heat and reduces chemical demand.

How many hours a day should I run my pool pump?

The general guidance is long enough to pass the entire volume of the pool through the filter once or twice a day. That is usually fewer hours than people run, and the run time is set by your pump's flow rate against your pool's volume, not by a fixed number.

Are fibreglass pools cheaper to run than concrete pools?

We could not verify a credible Australian figure for the difference, so we do not quote one. The costs that dominate — heating, evaporation and filtration — track the pool's volume, surface area and whether it is covered, rather than the shell material.

What is the cheapest way to heat a pool?

Solar, at roughly $96–$240 across a six-month season, against $300–$1,020 for a heat pump and $600–$1,500 for gas. Solar heats when the sun shines, so it lengthens the season rather than guaranteeing a set temperature.
