Quick answer
Is there a heat pump hot water rebate in NSW?
Eligible NSW households replacing a water heater with an approved air-source heat pump may access an upfront installation discount through the NSW Government's Energy Savings Scheme (ESS).
- up to $640 when replacing an electric water heater.
- up to $330 when replacing a gas water heater.
These are indicative maximums, not guaranteed payments. The actual discount depends on the system, installer and circumstances and is normally applied to the installation quote. Eligible systems may also benefit from separate federal small-scale technology certificates (STCs).
NSW + Federal Heat Pump Incentives Explained
NSW Energy Savings Scheme
Eligible heat pump and solar hot water upgrades can receive a variable upfront installation discount. A participating installer/provider checks scheme requirements, arranges the incentive and shows it on the quote.
Australian Government STCs
Eligible heat pump hot water systems can create small-scale technology certificates. Their value varies by eligible model and other factors and can reduce the effective purchase and installation cost. This is separate from the NSW discount.
Who May Be Eligible?
NSW households and small businesses may be eligible, but living in NSW does not automatically qualify you. A participating installer can check your specific situation before you commit.
- Your NSW property and whether the area is serviced
- The type and efficiency of your existing water heater
- The replacement model's scheme eligibility
- Appropriately licensed trades and a participating provider
- Current scheme requirements and required paperwork
Already have an efficient system? You may not qualify, as the NSW incentive depends on the energy savings of the upgrade.

Hot water is a significant energy use in many homes. Compare the costs and incentives before choosing an upgrade.
Two incentive layers
An eligible upgrade may access the NSW upfront discount and separate federal STCs. Ask for both to be itemised.
Uses less energy
According to energy.gov.au, heat pumps can use around 30% of the energy of conventional electric hot water systems.
Works with rooftop solar
Daytime scheduling may help you use more of your own solar electricity for hot water.
Check current rules
The standard NSW hot water upgrade incentive is currently open; eligibility and discount values can change.

How Much Could I Get? NSW Heat Pump Hot Water Discounts
The standard NSW Energy Savings Scheme hot water incentive is currently open with no announced closing date. Eligible federal STCs are a separate benefit; neither is a fixed payment to every household.
| Existing system | Potential NSW discount | Upgrade |
|---|---|---|
| Electric water heater | up to $640 | Eligible air-source heat pump |
| Gas water heater | up to $330 | Eligible air-source heat pump |
These are maximum indicative NSW Government amounts, not guaranteed rebates. Your actual discount depends on the eligible system, installer and circumstances. Ask for the NSW discount and any separate federal STC benefit to be shown individually on your quote.
How to Access the Discount
- 1. Check your existing systemIdentify whether it is electric, gas or another type.
- 2. Compare eligible modelsNot every heat pump water heater receives the same incentive.
- 3. Get multiple quotesAsk installers to itemise the NSW discount and any federal STC benefit.
- 4. Confirm eligibilityCheck the proposed system, provider and scheme rules before installation.
- 5. Complete the paperworkA participating provider should explain the required documentation.
- 6. Install the systemUse appropriately licensed tradespeople.
The NSW incentive is generally an upfront discount on the installation quote, rather than a conventional cashback claim after installation.
What You Actually Pay After Rebates
As a broad market guide, installed heat pump hot water systems can cost around $2,500–$5,500 before incentives. This is not a government price and your quote may fall outside that range. Compare the whole installed price, not just the headline discount.
| Quote line item | What to check |
|---|---|
| System price | Approved model, tank size and warranty |
| Installation cost | Plumbing, electrical work, switchboard, relocation and old-system disposal |
| NSW incentive | Your actual ESS upfront discount, if eligible |
| Federal STC benefit | Separate value for an eligible system, if applied |
| Final quoted price | The amount you pay after itemised discounts |
Installation complexity, travel, tariffs and product choice affect costs and savings. NSW requires a minimum customer payment; treat “$0 heat pump” claims with caution.
Why Heat Pumps Can Cut Hot Water Running Costs
A conventional electric storage heater turns electricity directly into heat. A heat pump moves heat from the surrounding air into the tank. Australian Government energy guidance says heat pumps can use about 30% of the energy of a conventional electric hot water system, but actual bill savings depend on hot-water use, tariffs, efficiency, climate, solar availability and operating schedule.
A suitable timer may let you run the unit when solar electricity is available or when an off-peak tariff applies. Ask the installer about settings that suit your household.
Heat Pump + Solar: Why They Work Well Together
If you have rooftop solar, scheduling a heat pump to run during daylight can use more of your own electricity instead of exporting it. Hot water will not always be free: weather, household demand and tariff settings matter. Compare solar panel options in NSW and model your own assumptions with our solar savings calculator.
Solar panels, batteries and hot water upgrades have separate program rules. You may be able to combine eligible incentives for distinct installations, but check each one rather than assuming a combined rebate. Read the NSW battery guide if you are considering storage too.
Choosing a Heat Pump Water Heater in NSW
Not all heat pumps are equally suitable or eligible for incentives. Compare capacity, noise, cold-weather performance, warranty and whether the model meets the current scheme rules. An installer can recommend a system sized to your household's hot-water demand.
Ask where the unit will sit, what electrical or plumbing changes are included, and how its timer will work with your tariff or solar generation.
Comparing Hot Water Systems
| System | Upfront cost / efficiency | Running cost / solar | Incentives / installation |
|---|---|---|---|
| Heat pump | Higher cost; high efficiency | Usually lower than electric storage; works with daytime solar | NSW discount and STCs may apply; check noise, space and climate |
| Electric storage | Usually lower upfront; less efficient | Often higher; off-peak tariff or solar can help | Check current eligibility; simple replacement may cost less |
| Gas | Varies; uses gas | Depends on gas pricing; not powered by rooftop solar | Switching to an eligible heat pump may attract a NSW discount; gas connection matters |
| Solar hot water | Higher upfront; uses solar heat | Lower energy use with appropriate backup heating | May be eligible for NSW incentives or STCs; roof space and plumbing matter |
These are general tendencies, not a promise that one technology is best for every home.

Frequently Asked Questions
Is there a heat pump rebate in NSW in 2026?
Yes. The NSW Energy Savings Scheme offers eligible households an upfront installation discount for an approved heat pump hot water upgrade. It is not a fixed cash rebate paid afterward.
How much is the NSW heat pump hot water rebate?
NSW Government guidance lists indicative maximum discounts of up to $640 for replacing an electric water heater and up to $330 for replacing a gas water heater with an eligible heat pump. Your actual discount depends on the system, installer and circumstances.
Can I get a rebate when replacing an electric hot water system?
You may be eligible for an upfront NSW discount of up to $640 when replacing an electric water heater with an eligible heat pump. Ask a participating installer to check your circumstances and show the discount on the quote.
Can I get a rebate when replacing a gas hot water system?
You may be eligible for an upfront NSW discount of up to $330 when replacing a gas water heater with an eligible heat pump. The actual amount varies.
Are heat pump hot water rebates paid in cash?
The NSW scheme generally applies an upfront discount through a participating installer or provider. It is not normally a cashback claim after installation, and a minimum customer payment still applies.
Can I receive NSW incentives and federal STCs?
An eligible heat pump system may benefit from both the NSW Energy Savings Scheme discount and federal small-scale technology certificates. Ask the installer to itemise each benefit; do not assume a fixed combined amount.
Which heat pump hot water systems qualify?
Not every model or replacement qualifies. Eligibility depends on the existing system, approved replacement model, location, provider and current scheme rules. A participating installer can check the proposed system.
Do I need an accredited installer?
Use appropriately licensed tradespeople and a provider participating in the NSW Energy Savings Scheme. If your chosen installer is not working with an Accredited Certificate Provider, they need to arrange that relationship for the NSW incentive.
How much does a heat pump hot water system cost after incentives?
The final quoted price varies with the system, installation work and applicable discounts. Ask for an itemised quote showing the system, labour, NSW incentive, any federal STC benefit and your required payment. Be cautious of $0 claims.
Can I run a heat pump hot water system using solar?
Yes. With rooftop solar, a suitable timer or control can run the heat pump during daylight to use more self-generated electricity. Actual bill savings depend on usage, tariffs, weather and system settings.
Do heat pump hot water systems work in cold weather?
Many models can work in cold NSW climates, but performance varies. Choose a model rated for your location and ask the installer how it operates in low temperatures.
