For Australian homeowners looking to reduce their energy bills and carbon footprint, 2026 presents a dynamic landscape of government incentives. While federal programs provide a baseline of support, Victoria, New South Wales, and the Australian Capital Territory (ACT) currently stand out as offering the most comprehensive and financially attractive rebate and loan packages for home energy upgrades. These states and territories provide a mix of upfront discounts, significant low- or zero-interest loans, and broad eligibility for a range of energy-efficient products, making them the frontrunners for maximising your savings.
Navigating the various schemes can be complex, but understanding the key programs in each region is crucial for unlocking thousands of dollars in potential savings on solar panels, home batteries, heat pumps, insulation, and more. This guide breaks down the current offerings across Australia, focusing on real 2026 figures and practical advice to help you make informed decisions.
Federal Support: The Foundation for Savings
At a national level, the Small-scale Renewable Energy Scheme (SRES) continues to be the primary federal incentive, reducing the upfront cost of installing eligible solar PV systems, solar water heaters, and air source heat pumps. This scheme works by creating Small-scale Technology Certificates (STCs), which your accredited installer typically assigns on your behalf for an immediate discount on your invoice. In 2026, STCs are trading at approximately $35 to $42 each. For a common 6.6kW solar system in Zone 3 (e.g., Brisbane), this can translate to an upfront discount of around $1,800 (based on ~45 STCs x $40). It’s important to note that the value of STCs decreases annually as the scheme winds down towards its 2030 conclusion, so acting sooner generally yields greater savings.
The Cheaper Home Batteries Program is another federal initiative, offering a discount on approved battery systems. From May 1, 2026, the program shifted to a tiered structure, providing approximately $252 to $272 per usable kilowatt-hour (kWh) for standard-sized batteries up to 14kWh. This means a 10kWh home battery could see an upfront discount of roughly $2,520 to $2,720.
While the universal Energy Bill Relief Fund provided automatic electricity bill credits to most Australian households in 2024-25 and the first half of 2025-26, this broad program concluded on December 31, 2025. Any ongoing energy bill relief in 2026 is now primarily through targeted state and territory concessions for eligible cardholders.
Victoria: Unmatched Breadth of Upgrades
Victoria consistently ranks as a leader in home energy upgrade incentives, offering a powerful combination of rebates and discounts through its Solar Homes Program and Victorian Energy Upgrades (VEU) program.
Solar Homes Program (Solar Victoria):
- Solar PV Rebate: Eligible owner-occupiers can receive up to $1,400 off the cost of installing rooftop solar panels. An optional interest-free loan of up to $1,400 is also available to further reduce upfront costs.
- Hot Water Rebate: Up to $1,000 for heat pump hot water systems or solar hot water systems, increasing to $1,400 for locally made products.
- Eligibility: From July 1, 2026, the combined household taxable income threshold for solar PV and hot water rebates changed to $150,000 per year.
Victorian Energy Upgrades (VEU) Program: The VEU program provides significant point-of-sale discounts on a wide array of energy-efficient products, making it one of the most robust schemes nationally.
- Heating and Cooling: Replacing an old ducted gas heater with a high-efficiency reverse cycle air conditioner can attract discounts upwards of $5,530. Upgrades from gas wall heaters to split systems typically range from $500 to $2,500. This program is a key driver in Victoria’s move away from gas.
- Insulation: From early 2026, incentives under VEU can halve the cost of installing ceiling insulation, reducing a typical $3,000 installation to around $1,500. This is expected to save households approximately $400 annually on energy bills.
- Other Upgrades: VEU also covers LED lighting replacements (often at very low or no cost), efficient electric hot water systems, and draught sealing.
“A Melbourne homeowner combining available government rebates for solar panels, heat pump hot water, and insulation upgrades can reduce upfront costs by $3,000–$6,000 in Victoria in 2026.”
New South Wales: Zero-Interest Loans & Targeted Discounts
New South Wales significantly bolstered its offerings with the launch of the Home Energy Saver Program on June 17, 2026. This $557 million initiative aims to remove upfront cost barriers for energy upgrades.
- Zero-Interest Loans: Eligible households with a combined taxable income of $210,000 or less can access zero-interest loans of up to $15,000, repayable over a maximum of 10 years. These loans cover a wide range of upgrades, including rooftop solar, household batteries, insulation, reverse-cycle air conditioning, heat pump hot water, switchboard upgrades, and EV chargers.
- Targeted Discounts: A separate discount of up to $4,000 is expected to open later in 2026 for lower-income households (combined income under $80,000 per year or eligible concession card holders). This discount can be combined with the zero-interest loan, with the discount applied first.
For many, the monthly loan repayment can be less than the monthly electricity savings, making these upgrades cash-flow positive from day one. This program significantly expands on previous NSW schemes and positions the state as a major player in residential energy efficiency.

ACT: Comprehensive Low-Interest Loans
The ACT Sustainable Household Scheme offers one of Australia’s most comprehensive finance programs for household electrification. From July 1, 2026, new applicants can borrow up to $20,000 (increased from $15,000) at a low 3% interest rate with up to 10 years to repay, and no upfront fees.
This scheme covers an extensive list of products:
- Solar battery storage systems
- Rooftop solar PV systems
- Electric vehicle chargers
- Electric heating and cooling systems (e.g., reverse cycle air conditioners)
- Hot water heat pumps and evacuated tube solar hot water systems
- Electric cooktops and appliances
- Ceiling insulation
- Electric vehicles and electric cargo bikes (from September 2026)
For eligible concession card holders, the ACT also offers the Home Energy Support Program, providing up to $5,000 in rebates for upgrades like solar panels and efficient electric appliances, which can be combined with a zero-interest loan of up to $10,000 through the Sustainable Household Scheme. This combination offers significant financial relief.
Other States: What’s Available Elsewhere
While Victoria, NSW, and ACT lead, other states and territories also offer valuable, albeit often more targeted, support:
- Queensland: Primarily relies on federal STCs for solar and the Cheaper Home Batteries Program. A 6.6kW solar system in Brisbane in 2026 may see around $1,600 off from the STC scheme. The Queensland EV incentive ended in September 2024.
- South Australia: The Retailer Energy Productivity Scheme (REPS) encourages retailers to offer discounts on energy-efficient products, including some home energy upgrades. Specific rebate amounts vary and are typically offered through accredited providers. Home Battery Scheme (HBS) was significant in the past, but current general residential rebates are less prominent than other states. Participating in a Virtual Power Plant (VPP) can also provide financial incentives in SA.
- Western Australia: The WA Government has established a $1.4 billion Clean Energy Fund for 2026-27, primarily supporting large-scale clean energy projects and grid infrastructure expansion, such as the Clean Energy Link. The Clean Energy Future Fund (CEFF) Round 4 for innovative projects closed in April 2026. Direct residential rebates are not as broadly available as in the leading states, but federal incentives still apply.
- Tasmania: The Energy Saver Loan Scheme offers interest-free loans for energy-efficient products, including solar panels, heat pumps, and insulation. Specific 2026 rebate amounts and broad program details are less publicly detailed than in the leading states.
- Northern Territory: The Home and Business Battery Scheme (HBBS) provides grants for battery storage, with specific amounts varying based on battery size and eligibility. The Solar Saver Scheme also offers support for solar installations.

Maximising Your Rebates: A Strategic Approach
To make the most of available incentives, consider these strategies:
- Combine Federal and State Programs: In many cases, state-based rebates and loans can be stacked with federal STC and Cheaper Home Batteries Program discounts. Always confirm eligibility with your installer. For example, a 6.6kW solar system with a 10kWh battery in Victoria could see the federal STC discount, the federal battery discount, and the Solar Victoria PV rebate applied, significantly reducing the net cost. A typical 6.6kW solar system might cost $5,500–$8,000 after STC discount, while a 10kWh battery might be $5,000–$6,500 after federal rebate. A combined system could range from $13,000–$22,000.
- Engage Accredited Installers: Most rebates are processed directly by accredited installers, who deduct the value upfront. Ensure you work with a Clean Energy Council (CEC) accredited installer for solar and battery systems, and VEU/ESS accredited providers for other upgrades. This ensures compliance and quality.
- Consider a Home Energy Assessment: An assessment can identify the most impactful upgrades for your specific home and confirm which rebates you qualify for.
- Explore Virtual Power Plants (VPPs): Even after rebates, a home battery can be a significant investment. Joining a VPP can provide additional income streams, often up to $1,500 annually, by allowing your battery to support the grid during peak demand.

- Act Promptly: Some rebate values, like STCs, decrease annually. Programs can also change or reach funding caps, so staying informed and acting decisively can secure better incentives.
Real Costs After Rebates: What to Expect
After applying federal and state incentives, the net cost of home energy upgrades can be substantially reduced. For instance:
- 6.6kW Solar System: Typically costs between $5,000 and $8,000 installed after the federal STC rebate. In Victoria, with the additional state rebate, this could drop even lower.
- 10kWh Home Battery: An average installed cost could be around $8,650 after the federal rebate, compared to over $12,000 three years ago. With state-level loans (NSW, ACT), the upfront out-of-pocket cost can be minimal.
- Heat Pump Hot Water System: In Victoria, VEU discounts can make these significantly more affordable, with installation costs potentially halved for some systems.
These figures are indicative and vary based on product brands (e.g., Tesla Powerwall, SonnenBatterie, BYD Battery Box), installation complexity, and specific eligibility. Always obtain multiple itemised quotes to compare.
Bottom Line
For Australian homeowners in 2026, Victoria, New South Wales, and the ACT offer the most compelling government support for home energy upgrades. Victoria’s VEU program provides deep discounts across a broad spectrum of energy efficiency measures, while NSW’s new Home Energy Saver Program and the ACT’s Sustainable Household Scheme offer substantial low- or zero-interest loans that make comprehensive electrification highly accessible. If you reside in one of these regions, you are in the best position to significantly reduce the upfront cost of solar, batteries, and other energy-efficient upgrades. For those in other states, federal incentives still provide valuable savings, but a more targeted approach to specific upgrades may be necessary. Regardless of your location, researching and leveraging these programs is a crucial step towards a more energy-efficient and cost-effective home.
