Australian homeowners and renters can save thousands of dollars on energy-efficient upgrades in 2026, thanks to a robust suite of federal and state government rebates, loans, and incentives. These programs are designed to reduce upfront costs for solar panels, home batteries, heat pump hot water systems, energy-efficient appliances, and even electric vehicle (EV) chargers, making cleaner energy more accessible and affordable across the nation. While federal schemes provide a baseline of support, individual states and territories offer additional, often substantial, incentives that can significantly cut your out-of-pocket expenses.
Federal Government Programs: The National Backbone
The Australian Government provides foundational support for energy upgrades, which can often be stacked with state-specific programs for maximum savings.
Small-scale Renewable Energy Scheme (SRES) / Small-scale Technology Certificates (STCs)
This long-standing federal scheme offers an upfront discount on eligible small-scale renewable energy systems, including rooftop solar PV, solar water heaters, and air source heat pumps. The value of STCs is calculated based on your system’s size, geographical location, and the deeming period (years until 2030 when the scheme is set to conclude). Crucially, the STC value steps down annually on January 1st, meaning installing sooner typically yields a larger discount. For instance, a 6.6kW solar system in Brisbane could see an STC value of approximately $2,800 to $3,200 in 2026. The eligibility for solar PV systems under SRES was expanded from 100kW to 1MW in August 2026, subject to new regulations.
Cheaper Home Batteries Program
Launched in July 2025, this federal initiative provides an upfront discount on eligible home battery systems (5-100kWh) when connected to new or existing rooftop solar. The discount is applied directly by your installer at the point of sale. As of May 1, 2026, the rebate value was adjusted and is now tiered based on battery capacity: the full rate applies to the first 14 kWh of usable capacity (approximately $252 per usable kWh), with reduced support for capacity between 14-28 kWh, and further reduced support for 28-50 kWh. This adjustment ensures the discount remains around 30% and aligns with falling battery costs. A typical 10kWh battery can cost around $5,000 after this federal rebate, while a 13kWh battery might be around $6,000.
Household Energy Upgrades Fund (HEUF)
Backed by $1 billion, the HEUF, managed by the Clean Energy Finance Corporation (CEFC), offers discounted consumer finance products (low-interest loans) to help households upgrade their homes. This fund supports a wide range of improvements, including solar PV systems, battery storage, modern energy-efficient appliances, insulation, and double-glazed windows. Households utilising HEUF finance have reportedly saved an average of $1,700 to $2,300 annually on electricity bills and around $570 on loan interest in the first year. Participating lenders include Plenti, Westpac, ING Australia, and Commonwealth Bank of Australia.
Energy Bill Relief Fund
All Australian households and eligible small businesses can receive a direct credit on their electricity bills through the Federal Government’s Energy Bill Relief Fund. The specific credit amount varies by state.
Electric Vehicle (EV) Incentives
While universal home EV charger rebates are not currently available across Australia, the Federal Government provides a Fringe Benefits Tax (FBT) exemption for eligible EVs until March 31, 2027. This can save employees $6,000-$14,000 annually when combined with a novated lease. The Federal Small Business Energy Incentive also offers a 20% bonus deduction for eligible assets up to $100,000, which can cover commercial EV charger installations.
State-by-State Guide to Energy Rebates 2026
Beyond federal support, each state and territory offers unique programs to further reduce costs.
New South Wales (NSW)
The NSW Government’s Home Energy Saver Program, launched in June 2026, is a significant initiative. It offers eligible households zero-interest loans of up to $15,000 for energy-saving home upgrades, including rooftop solar, home batteries, insulation, heat pumps, reverse-cycle air conditioning, and Level 2 EV chargers. These loans are repayable over up to 10 years and are administered by approved finance providers like Brighte and Plenti. For lower-income households (combined income under $80,000 or concession card holders), a separate direct discount of up to $4,000 is expected to open later in 2026, requiring a minimum customer contribution of $200.
Victoria (VIC)
Victoria offers a comprehensive suite of state-backed incentives:
- Solar Homes Program: Provides a solar panel rebate of up to $1,400, alongside an interest-free loan of up to $1,400. From July 1, 2026, the household income cap for eligibility was tightened from $210,000 to $150,000 per year.
- Hot Water Rebate: Covers up to 50% of the cost of an eligible heat pump or solar hot water system, capped at $1,000, or up to $1,400 for Australian-made systems.
- Victorian Energy Upgrades (VEU) program: Offers upfront discounts on various energy-efficient upgrades, including hot water systems, efficient heating/cooling, induction cooktops, and weatherproofing. Renters are eligible, and the discount is applied directly to the installation invoice. The VEU scheme has been extended through to 2045.
“Victorian households can claim five main energy rebates in 2026: the federal STC solar discount, the federal Cheaper Home Batteries Program, the Solar Homes solar panel rebate, an interest-free Solar Homes loan, and Victorian Energy Upgrades (VEU) discounts.”
Queensland (QLD)
While the Queensland Government’s Battery Booster Program closed in May 2024, residents can still access federal STCs for solar and the Cheaper Home Batteries Program. Additionally, Queensland offers interest-free loans of up to $10,000 for home battery storage. The state’s Home Energy Support Program provides grants of up to $5,000 for energy-efficient upgrades like ceiling insulation, particularly focused on combating heat in subtropical climates.
South Australia (SA)
South Australia’s Retailer Energy Productivity Scheme (REPS) mandates energy retailers to offer discounted or free upgrades for efficient hot water, reverse-cycle air conditioning, and energy-efficient appliances. From 2026, REPS targets are more focused on Priority Group households, potentially offering higher benefits for eligible customers. SA also provides an incentive of up to approximately $2,050 for connecting a new battery to an approved Virtual Power Plant (VPP) under REPS. Homeowners can also find appliance rebates offering up to $600 cashback on energy-efficient dryers, fridges, or fridge/freezers. Some Adelaide councils, such as Adelaide Hills Council, offer smaller, stackable rebates of $250-$500 for energy-efficient upgrades.
Western Australia (WA)
Western Australia has introduced a new battery subsidy ranging from $1,300 to $3,800. Further details on specific eligibility and application processes should be confirmed with the WA government.
Australian Capital Territory (ACT)
The ACT’s Sustainable Household Scheme provides eligible households with 3%-interest loans of between $2,000 and $15,000 to cover the upfront costs of solar, batteries, and EV charging infrastructure.
Northern Territory (NT)
Homeowners in the NT can claim a $1,000 rebate for EV home charger installation, which was available until June 30, 2026. The NT also offers free registration for new and existing plug-in electric vehicles (PEVs) and a stamp duty concession of up to $1,500.
Tasmania (TAS)
Tasmanian residents primarily benefit from federal schemes, including STCs for solar and heat pumps, and the Cheaper Home Batteries Program. There are no prominent state-specific energy upgrade rebates identified for 2026 beyond these federal programs.
How to Maximise Your Savings
The key to saving thousands lies in strategically combining federal and state incentives. Many programs are designed to be stackable. For instance, a Victorian household installing a heat pump hot water system could benefit from federal STCs, the Victorian Hot Water Rebate, and VEU discounts. Similarly, a NSW resident could use the Home Energy Saver loan for a solar and battery system, while also claiming the federal Cheaper Home Batteries discount.
Consider linking your battery to a Virtual Power Plant (VPP) where available, as this can unlock additional incentives like the SA REPS VPP incentive, and provide ongoing earnings. To explore this further, read our guide: Join a VPP in 2026: Earn Up To $1,500 Annually & Boost Grid Stability.

Important Considerations
- Eligibility: Always check the specific income thresholds, property requirements (e.g., owner-occupier vs. renter), and product approvals for each scheme. Eligibility criteria can change, as seen with Victoria’s Solar Homes income cap reduction.
- Accredited Installers: Most rebates require installation by Clean Energy Council (CEC) accredited installers using CEC-approved products to ensure quality and safety.
- Application Process: Some rebates are applied upfront by the installer, while others require direct application. Understand the process to avoid missing out.
- Timing: Federal STC and Cheaper Home Battery Program values are subject to annual step-downs, meaning the incentive amount decreases each year until 2030. Acting sooner can often secure a larger benefit.
Bottom Line
In 2026, Australian households have unprecedented opportunities to significantly reduce the cost of energy-efficient upgrades. By understanding and strategically combining federal incentives like the STC scheme and the Cheaper Home Batteries Program with state-specific initiatives such as NSW’s Home Energy Saver loans, Victoria’s Solar Homes rebates, or South Australia’s REPS program, you can save thousands of dollars upfront. These savings, coupled with reduced energy bills, make investing in a greener, more sustainable home a financially sound decision. Don’t delay, as many incentives are designed to taper over time.
