Australian homeowners and renters can access substantial government grants and rebates in 2026 to reduce the upfront cost of energy-efficient upgrades. These incentives, offered at both federal and state levels, cover everything from rooftop solar and home batteries to efficient hot water systems and insulation, potentially saving households thousands of dollars. However, the landscape is dynamic, with schemes frequently updated, making it crucial to understand current eligibility and available amounts.
Federal Government Energy Upgrade Incentives 2026
At a national level, the Clean Energy Regulator (CER) administers the primary schemes driving home energy upgrades across Australia.
Small-scale Renewable Energy Scheme (SRES) for Solar PV
This is Australia’s foundational solar rebate, delivered through Small-scale Technology Certificates (STCs). When you install an eligible solar PV system, your installer typically calculates the value of these STCs and applies it as an upfront discount on your invoice. The value of STCs is subject to change, and on 1 January 2026, the deeming period for STCs dropped from six years to five years, resulting in an approximate 15-20% reduction in the upfront discount for new solar panel installations.
For example, a typical 6.6kW solar system in Sydney might see an STC value reduction from around $3,500 in late 2025 to approximately $2,800-$3,000 in 2026, depending on location and prevailing STC market prices. For insights into current market offerings, refer to our guide on Best Value Solar Panels Australia 2026: Systems from $0.88/Watt Installed.
Additionally, from 1 October 2026, the SRES expanded to include mid-scale solar PV systems (100 kW to 1 MW), which will benefit from a fixed 5-year deeming period.
Cheaper Home Batteries Program (Federal Battery Rebate)
Launched to encourage battery storage adoption, this federal program provides a discount on eligible home battery systems. Significant changes were introduced on 1 May 2026, moving from a flat rate to a tiered rebate structure designed to incentivise appropriately sized systems for residential use. The STC factor for batteries decreased from 8.4 to 6.8, leading to a general reduction in the upfront discount, now roughly 30% off the upfront cost.
The federal Cheaper Home Batteries Program offers approximately $252 per usable kWh for the first 14 kWh of battery capacity.
The rebate is tiered as follows, with the next scheduled step-down on 1 January 2027:
| Capacity Band | Rebate Rate (approx.) | Notes |
|---|---|---|
| First 0–14 kWh | ~$252 / kWh | Full rate – captures most of the discount |
| 14–28 kWh | ~$151 / kWh | 60% of the full rate |
| 28–50 kWh | ~$38 / kWh | 15% of the full rate |
This means a 10 kWh home battery like a BYD Battery-Box Premium HVM 12.8 (with 12.8 kWh usable capacity) could see an upfront discount of approximately $3,225 (12.8 kWh * $252/kWh).

State and Territory Government Programs 2026: A State-by-State Guide
Beyond federal incentives, each state and territory offers unique programs for home energy upgrades.
New South Wales (NSW)
NSW leads with the Home Energy Saver Program, launched on 17 June 2026, backed by $557 million in funding. This program offers:
- Zero-interest loans of up to $15,000 for eligible households with a combined taxable income up to $210,000. Loans are repayable over up to 10 years.
- A separate discount of up to $4,000 for lower-income households (taxable income up to $80,000 or concession card holders), including renters with landlord consent. This discount is expected to open later in 2026.
Eligible upgrades include rooftop solar, home batteries, heat pump and electric-boosted solar water heaters, reverse-cycle air conditioning, ceiling insulation, double glazing, induction cooktops (replacing gas), Level 2 EV chargers, draught proofing, ceiling fans, switchboard upgrades, and NatHERS assessments.
The NSW Energy Savings Scheme (ESS) also provides upfront discounts on heat pump hot water systems (which also benefit from federal STCs, though these decline from Jan 2027), and reverse-cycle air conditioning. From 1 July 2026, a minimum co-payment of $500 applies for air conditioning systems under 10 kW.
Victoria (VIC)
Victoria offers some of the most comprehensive state-level incentives:
- Victorian Energy Upgrades (VEU) Program: Extended to 2045, VEU provides point-of-sale discounts (no income test) on a wide range of energy-saving products. From 1 October 2026, it includes ceiling insulation discounts of up to $1,500 in Melbourne and $2,100 in regional Victoria. Other eligible upgrades include heat pump hot water (combinable with Solar Victoria rebates), reverse-cycle air conditioning (new limits from 30 September 2026), induction cooktops, draught-proofing, and efficient showerheads.
- Solar Homes Program (Solar Victoria): Provides rebates of up to $1,400 for solar panel installations and up to $1,400 for hot water systems. Eligibility typically includes an income test for homeowners.
Queensland (QLD)
Queensland has programs such as the Queensland Climate Smart Energy Savers Program and offers interest-free loans for solar and batteries, as well as household energy efficiency upgrades. Specific 2026 eligibility criteria and detailed rebate amounts require direct consultation with the Queensland Government’s energy department, as detailed, current figures for households were not readily available in the provided data.
South Australia (SA)
While the SA Home Battery Scheme closed in 2022, South Australians can still leverage federal incentives and state-specific programs:
- Federal Cheaper Home Batteries Program: This remains the primary battery discount, offering tiered savings as detailed above.
- Retailer Energy Productivity Scheme (REPS): REPS offers an incentive of up to $2,050 for connecting an eligible battery to an approved Virtual Power Plant (VPP). However, as of May 2026, general REPS funding for this incentive was fully allocated, with applications currently only open to priority group households. This includes Pensioner Concession Card or Health Care Card holders, recipients of the SA energy bill concession, households on a retailer hardship program, or renters paying $500/week or less.
- City of Adelaide Battery Grant: Residents in specific Adelaide CBD postcodes (5000, 5006) can receive an additional $1,000 bonus for battery installations, stackable with other incentives.
Western Australia (WA)
Western Australia’s government funding for clean energy in 2026 primarily focuses on large-scale projects and innovation rather than direct household rebates for upgrades:
- Clean Energy Future Fund (CEFF): Round 4, with $9 million allocated, closed applications on 20 April 2026. This fund provides grants from $100,000 to $4 million (up to 25% of project costs) for testing and demonstrating innovative clean energy technologies, primarily for businesses and research bodies, not direct residential upgrades.
- A $1.4 billion Clean Energy Fund was announced in April 2026 to support state decarbonisation projects, to be detailed in the 2026-27 State Budget, also not a direct household rebate scheme.
Households should investigate the Distributed Energy Buyback Scheme (DEBS) for feed-in tariffs, but this is an ongoing payment mechanism, not an upfront upgrade grant.
Tasmania (TAS)
Tasmania operates an Energy Saver Loan Scheme which typically provides access to finance for energy efficiency upgrades. However, specific 2026 details on loan amounts, interest rates, and eligible products for households were not readily available in the provided data. Tasmanian residents should consult the state government’s energy department for the most current information.
Australian Capital Territory (ACT)
The ACT boasts one of Australia’s most comprehensive household electrification finance programs:
- Sustainable Household Scheme (SHS): This scheme offers low-interest loans (currently ~3% p.a., no upfront fees) repayable over up to 10 years. From 1 July 2026, new applicants can borrow up to $20,000 (an increase from the previous $15,000 cap) across eligible products.
Eligible upgrades include solar battery storage systems, rooftop solar PV systems, EV chargers, electric heating and cooling systems (heat pumps), hot water heat pumps, electric cooktops, ceiling insulation, and electric vehicles.
- Go Electric Pilot Program: For residents in Banks and surrounding suburbs, this Australian Government-funded program assists eligible homeowners and renters in switching from gas to electric, covering solar, batteries, and EV charging. It can be combined with the SHS.
Northern Territory (NT)
The Northern Territory has historically offered schemes such as a Home Energy Audit and Solar Rebate. However, specific 2026 details regarding current household-focused grants, rebate amounts, or eligibility criteria were not available in the provided search results. NT residents are advised to check the NT Government’s official energy and climate change websites for the latest programs.
Accessing Your Rebates and Grants
For most federal and state schemes, the rebate or discount is applied at the point of sale by an accredited installer or provider. This means you typically see a lower upfront cost rather than receiving a cash payment after installation. It is critical to use Clean Energy Council (CEC) approved products and installers to ensure eligibility. Many government programs also require a valid NatHERS energy rating certificate.
Bottom Line
In 2026, Australian households have significant financial incentives to undertake energy upgrades, particularly for solar panels and home batteries, with the federal STC scheme and Cheaper Home Batteries Program forming the national backbone. State-specific programs, notably the NSW Home Energy Saver Program (offering up to $15,000 interest-free loans) and Victoria’s VEU and Solar Homes programs (offering up to $1,400 solar and $2,100 insulation rebates), provide substantial additional savings. It is essential to engage with accredited providers and verify eligibility for current programs, as amounts and criteria are subject to ongoing adjustments. Acting sooner rather than later can often maximise savings, particularly with federal STC values declining annually. Research your state’s specific offerings and speak to multiple accredited installers to secure the best combination of incentives for your home.
