Small-scale Technology Certificates (STCs)
Applied as a point-of-sale discount. Value varies by system type and climate zone. Available Australia-wide until 2030.
STCs are the one incentive every state and territory shares. Your installer claims them for you and takes the value straight off your quote, so the price you are quoted should already include the discount. Everything below stacks on top of this.

How the rebates stack: Victoria example
Victoria has the strongest combination in Australia because three separate schemes apply to the same installation:
After stacking all three, the average installed cost in Victoria lands at $2,200 - $4,500. Victoria also has a gas ban from 1 March 2027, when end-of-life gas hot water systems in existing homes must be replaced with an efficient electric alternative. See the complete Victorian gas ban guide or the Victoria rebate guide for eligibility details.

What is the federal heat pump hot water rebate?
The federal incentive is Small-scale Technology Certificates (STCs). The value varies by system type and climate zone, and is typically $500 to $700. It is applied as a point-of-sale discount by your installer, so you do not need to claim it separately. STCs are available Australia-wide until 2030.
Is there a heat pump rebate in NSW?
Yes. The NSW Energy Savings Scheme (ESS) provides certificate discounts worth $300 to $700, applied at point of sale by participating retailers: up to $640 when replacing an electric hot water system and up to $330 when replacing gas. Gas-to-gas replacement activities end 1 July 2026. Federal STCs stack on top, taking total savings in New South Wales to around $1,400.
Is there a heat pump rebate in QLD?
Queensland does not currently offer a state heat pump rebate. Queensland households still receive the federal STC discount, typically $500 to $700 at point of sale. Queensland has a warmer climate, which means heat pumps run at excellent efficiency year-round and keep running costs low.
Which state has the biggest heat pump rebates?
Victoria. The Solar Victoria Hot Water Rebate is worth $1,000 to $1,400 (household income threshold of $210,000 for applications by 30 June 2026, dropping to $150,000 from 1 July 2026, property value under $3 million, and you must use a Solar Victoria registered installer, with up to $1,400 for Australian-made systems). Victorian Energy Upgrades (VEU) certificates add $400 to $1,000, and federal STCs stack on top, for total savings of up to $3,100.
Can I stack federal and state rebates?
Yes. Federal STCs apply Australia-wide, and state rebates and certificate schemes apply on top of them. In Victoria, for example, a household can combine STCs, the Solar Victoria Hot Water Rebate, and VEU certificates for up to $3,100 off a heat pump hot water system.
What help is available in the ACT?
The ACT Sustainable Household Scheme offers a low-interest loan (3% fixed) of $2,000 to $20,000 over up to 10 years for homeowners and renters (with landlord approval). It covers heat pumps, solar, batteries, EV chargers, and insulation. It is a loan rather than a rebate, and federal STCs still apply on top. The $20,000 maximum applies to new applicants approved on or after 1 July 2026 ($15,000 for earlier applicants).
How do I claim heat pump rebates?
Most schemes are applied for you. STC, VEU, ESS, and REPS discounts are applied at point of sale by participating retailers and installers, so they come straight off your quote. The Solar Victoria Hot Water Rebate requires an application and a Solar Victoria registered installer. Getting quotes from installers who work with these schemes is the simplest way to capture every discount you are eligible for.
