For Australians looking to reduce their energy bills and carbon footprint, 2026 continues to offer a range of green home grants and incentives. While the landscape of rebates is dynamic, both federal and state governments are actively supporting energy efficiency upgrades, from solar panels and battery storage to heat pump hot water systems and insulation. The key is understanding which programs are available in your specific state or territory and how to maximise your savings.
This comprehensive guide outlines the current green home grants and incentives available across Australia in 2026, providing real figures and practical advice to help you make informed decisions.
Federal Government Energy Efficiency Programs 2026
At a national level, several key programs underpin energy efficiency upgrades across Australia:
- Small-scale Renewable Energy Scheme (SRES): This scheme provides an upfront discount on eligible solar PV systems, solar hot water systems, and heat pump hot water systems through Small-scale Technology Certificates (STCs). The value of STCs varies based on your location (STC zone), system size, and the prevailing market price of STCs. For a typical 6.6kW solar system, this rebate can reduce the cost by approximately $1,700–$1,800 in Zone 3 (e.g., Sydney). The STC rebate decreases by approximately 6.7% annually until 2030, making 2026 an optimal year to install.
- Cheaper Home Batteries Program: Introduced in July 2025, this federal initiative provides a rebate on battery storage systems, also delivered via STCs. For a typical 10–13.5 kWh battery, this can reduce upfront costs by approximately $3,500–$4,700, although changes to the rebate took effect from 1 May 2026 with step-downs scheduled over time. Each kilowatt-hour (kWh) of battery storage will earn 6.8 STCs for the remainder of 2026.
- Household Energy Upgrades Fund (HEUF): This $1 billion fund, managed by the Clean Energy Finance Corporation (CEFC), partners with private lenders (like Plenti and Westpac) to offer discounted green loans for energy-efficient home retrofits. In 2026, it focuses on fast-tracking the transition to all-electric homes by subsidising low-interest finance for double-glazing, insulation, heat pump hot water heaters, and battery storage.
- National Energy Bill Relief (2025-26 Extension): Extended for the 2025-26 financial year, this program provides a direct credit of $150 to electricity bills for most eligible Australian households, typically applied in quarterly instalments.
State-by-State Green Home Grants in 2026
While federal incentives provide a baseline, state and territory governments offer targeted programs that can significantly boost your savings.
New South Wales (NSW)
NSW focuses on energy savings through its Energy Savings Scheme (ESS) and Peak Demand Reduction Scheme (PDRS). These are often applied as upfront discounts by accredited providers.
- Energy Savings Scheme (ESS): Provides financial incentives for installing energy-efficient equipment. This includes discounts on high-efficiency heat pump hot water systems (typically $190 to $670) and energy-efficient air conditioners. For a new 6kW reverse-cycle split system AC, you could expect an upfront discount of approximately $550. Ducted systems can attract $1,000 to $1,200 in discounts.
- Peak Demand Reduction Scheme (PDRS): In 2026, the PDRS has been updated to streamline Virtual Power Plant (VPP) incentives. Homeowners connecting a battery to a VPP can claim up to 6 years of incentives upfront, with values ranging from approximately $550 to $1,500 for a 10 kWh to 27 kWh battery system. Note: Standard battery installation incentives under PDRS are currently suspended to avoid double-dipping with the Federal Cheaper Home Batteries Program.
- NSW Energy Bill Relief: In addition to the federal relief, NSW offers various rebates for eligible low-income households, families, seniors, and those with medical conditions to help manage ongoing electricity costs.
Victoria (VIC)
Victoria boasts one of the most comprehensive state-level schemes, combining rebates and financing:
- Victorian Energy Upgrades (VEU) Program: This program offers point-of-sale discounts on a wide range of high-efficiency products, including heat pump hot water systems (typically $600-$1,000 when replacing electric or gas), efficient air conditioners, and glazing incentives (saving around $350 per window). From April 14, 2026, ceiling insulation has been formally introduced as a new rebate activity, expanding to all eligible residential homes on October 1, 2026.
- Solar Homes Program: Offers rebates for solar panel (PV) systems, solar battery storage, and solar or heat pump hot water systems. Homeowners can receive a rebate of up to $1,400 for solar PV and up to $1,400 for solar hot water or heat pump hot water systems (or $1,000 for non-Australian made units). A battery rebate of up to $1,400 is also available for eligible households, often combined with a Virtual Power Plant (VPP) program.

Queensland (QLD)
Queensland’s previous ‘Battery Booster’ program has closed, with homeowners now relying on the Federal Cheaper Home Batteries Program.
- Solar for Rentals: This program assists landlords in installing solar PV systems on rental properties, benefiting tenants with lower electricity bills.
South Australia (SA)
SA focuses on grid stability and energy efficiency:
- Retailer Energy Productivity Scheme (REPS): Similar to VEU and ESS, REPS encourages energy retailers to help households and businesses reduce energy consumption by offering incentives for energy-efficient upgrades, including insulation, efficient lighting, and hot water systems.
- Virtual Power Plant (VPP) Incentives: SA has been a leader in VPPs. While the state’s Home Battery Scheme has largely transitioned, federal and VPP operator incentives are still available for battery storage connected to the grid.
Australian Capital Territory (ACT)
The ACT has a robust scheme focused on electrification:
- Sustainable Household Scheme (SHS): Provides low-interest loans (currently 3% interest) of up to $15,000, repayable over up to 10 years, for a wide range of energy-efficient products. From 1 July 2026, the maximum loan limit will increase to $20,000 for new applicants. Eligible upgrades include solar panels, household battery storage systems, electric heating and cooling (heat pumps), hot water heat pumps, electric stove tops, electric vehicles (EVs), and EV charging infrastructure. From September 2026, electric cargo bikes will also be eligible.
- Home Energy Support Program: Offers rebates for concession card holders to cover costs of rooftop solar, hot water systems, ceiling insulation, and reverse-cycle heating and cooling.
Western Australia (WA)
WA homeowners primarily benefit from federal STCs for solar and heat pumps. State-specific incentives are generally less comprehensive for residential energy efficiency upgrades than in eastern states.
- EV Charger Rebates: While primarily for businesses, WA has offered incentives for EV charging infrastructure, with some past programs covering 50% of purchase and installation costs (up to $10,000) for eligible chargers, and 75% of a 2-year software subscription.

Maximising Your Green Home Savings
To effectively leverage these grants and rebates, consider the following:
- Check Eligibility: Each program has specific criteria, often related to income, property type, or existing energy infrastructure. Always verify your eligibility with official government websites or accredited installers.
- Combine Programs: Where possible, stack federal and state incentives. For example, a Victorian homeowner might combine federal STCs for solar panels with a Solar Homes battery rebate and VEU incentives for a heat pump hot water system.
- Work with Accredited Installers: Many rebates are administered by approved providers who apply the discount directly to your quote and handle the paperwork for certificates (e.g., STCs, ESCs, VEECs). This simplifies the process significantly.
- Consider Green Loans: Federal programs like HEUF and state-specific loan schemes (e.g., ACT Sustainable Household Scheme, Tasmania Energy Saver Loan Scheme) offer low-interest financing to cover upfront costs, making upgrades more accessible.
- Focus on Electrification: The trend in government incentives is towards electrifying homes, replacing gas appliances with efficient electric alternatives like heat pumps and induction cooktops. This strategy not only reduces emissions but also aligns with future energy policy direction. For more on this, see: Ditch Gas & Save $1,000+ Annually: Your 2026 Australian Home Electrification Guide
