As Australian energy costs continue to challenge household budgets, upgrading to energy-efficient appliances and improving home insulation is no longer just about environmental consciousness; it’s a critical strategy for financial relief. In 2026, a combination of federal and state government programs offers Australians significant financial incentives, potentially saving thousands of dollars on essential home upgrades like solar panels, home batteries, and heat pump hot water systems.
While the universal federal energy bill relief payments concluded on December 31, 2025, targeted rebates and low-interest loans for energy-efficient upgrades are more robust than ever. This guide provides a comprehensive, state-by-state breakdown of the key schemes available to help you reduce your energy bills and enhance your home’s comfort and value.
Federal Government Energy Upgrade Support 2026
The Albanese Labor Government has committed substantial funds to accelerate Australia’s transition to a cleaner, more efficient energy system. These national initiatives complement state-based programs, often allowing for ‘stacking’ of incentives to maximise your savings.
1. Small-scale Renewable Energy Scheme (SRES) & STCs
This long-standing federal scheme provides an upfront discount on eligible small-scale renewable energy systems, primarily solar PV systems and heat pump hot water systems, through Small-scale Technology Certificates (STCs). The value of STCs is calculated based on the expected electricity generation of your system over its lifetime.
On January 1, 2026, the deeming period for new solar panel installations under the SRES dropped from 6 years to 5 years, resulting in a roughly 15–20% reduction in the upfront discount.
This means installing earlier in 2026 can still offer a greater benefit before further annual step-downs occur. For a typical 6.6kW solar system, the STC rebate can still reduce the upfront cost by around $2,500 - $3,500, depending on your location and the current STC market value.
2. Cheaper Home Batteries Program (CHBP)
This federal program, launched in July 2025, provides a significant upfront discount on eligible home battery systems, also delivered through the STC framework. However, a major change took effect on May 1, 2026.
| Battery Size (Usable kWh) | STC Factor (Before May 1, 2026) | Approx. Rebate Value (@$38/STC) | STC Factor (From May 1, 2026) | Approx. Rebate Value (@$38/STC) |
|---|---|---|---|---|
| 0-14 kWh | 8.4 STCs/kWh | Up to $5,300 (for 14kWh) | 6.8 STCs/kWh (100%) | Up to $3,600 (for 14kWh) |
| 15-28 kWh | 8.4 STCs/kWh | Up to $9,500 (for 28kWh) | 6.8 STCs/kWh (60%) | Up to $6,500 (for 28kWh) |
| 29-50 kWh | 8.4 STCs/kWh | Up to $15,300 (for 48kWh) | 6.8 STCs/kWh (15%) | Up to $7,000 (for 48kWh) |
Note: Rebate values are approximate, based on an STC price of $38, and can vary.
Despite the reduction from May 1, 2026, the CHBP still offers a substantial discount, making battery storage more accessible. Over 350,000 home battery installations were completed under the CHBP from July 2025 to May 2026, indicating strong uptake.
