Battery Rebates Changes Dec 2025 in Australia

Australia’s home battery rebates have recently changed following new federal funding announcements. While billions of dollars have been added to support cheaper home batteries, the way rebates are applied has shifted, particularly for larger systems. These changes are designed to support more households over a longer period while better matching typical residential energy needs.

If you are considering installing a home battery, upgrading an existing system, or reviewing a recent quote, here is what you need to know.

Increased Funding for Cheaper Home Batteries
The Australian Government has committed additional funding to the Cheaper Home Batteries Program, increasing total investment to around $7.2 billion dollars over the coming years.

This increased funding means
• Rebates will remain available for more households
• The program is expected to continue through to 2030
• Battery storage will continue to be accessible for more Australian homes.

When the Rebate Changes Take Effect
The updated rebate structure applies from 1 May 2026.

From this date, rebates will be calculated using a tiered model based on battery size rather than a single flat rate. This approach prioritises typical household battery systems while helping ensure the program remains financially sustainable over the long-term.

How the New Battery Rebate Structure Works
Under the revised program, rebates are applied based on battery capacity.

  • Batteries up to 14 kilowatt hours receive the full rebate available.
    • Batteries between 14 and 28 kilowatt hours receive 60% of the available rate.
    • Batteries between 28 and 50 kilowatt hours receive 15% of the available rate.

Larger systems remain eligible, but the rebate per kilowatt hour decreases as battery size increases. 

Importantly, as your battery increases in size, the rebate paid per tier is paid in full. As an example, if you purchase a 32 kilowatt battery, you would receive 100% of the rebate on the first 14 kilowatts of capacity, 60% of the rebate on the second 14 kilowatts (14-28 kilowatt system), and 15% of the rebate for the remaining 4 kilowatts. 

Why Rebates for Larger Batteries Have Been Reduced
The earlier rebate structure was taken up very quickly, particularly by larger battery installations.

This created two key challenges:
• Large systems were using a disproportionate share of available funding.
• There was a risk the program would run out of funding sooner than planned.

By adjusting the rebate structure, funding can be spread more evenly across more households, as was intended, while remaining available over the long-term.

What This Means for Households Considering a Battery
For many households, these changes will have little impact. Smaller and mid-sized batteries continue to receive strong rebate support and often provide the best balance of cost, performance, and energy independence.

Households should consider
• Current and future electricity usage
• Whether backup power is a priority
• Plans for electric vehicles or broader home electrification
• How rebates apply to different battery sizes.

How Federal Rebates Work Alongside State Incentives
Federal battery rebates may be combined with state based incentives, depending on location and eligibility rules.

In some states, additional incentives may apply when batteries are connected to programs such as virtual power plants (VPP). Eligibility varies by state, so it is important to check how incentives apply to your specific system and location.

Are Larger Batteries Still Worth It
Yes, in the right circumstances. While rebates for larger systems are lower, battery prices continue to decline and the value of energy resilience and energy trading continues to rise.

Larger batteries may still suit households that
• Have high electricity usage
• Experience frequent power outages
• Are off-grid or partially off-grid
• Plan to add electric vehicles or electrify heating and cooking.

The key is selecting a system size that reflects real energy needs rather than maximising rebate value alone.

Final Thoughts on the Battery Rebate Changes
The updated home battery rebate structure reflects a more mature energy storage market in Australia. By increasing funding while adjusting rebate levels, the government aims to support more households over the long-term.
