Since 1 July 2025, both the WA and Federal governments have been offering generous incentives to reduce the upfront cost of purchasing and installing a home battery.
These incentives are the:
- WA Residential Battery Scheme
- Federal Cheaper Home Batteries Program
The Federal Government also offers a solar rebate through its Small-scale Renewable Energy Scheme.
How Kleenheat Spark makes it easy
When you request a quote from Kleenheat, we’ll automatically apply the government rebates you’re eligible for to the packages we recommend. If you decide to go ahead, your installer will claim the rebates on your behalf.
That means you only pay the remaining balance – no hassle.
You can learn more about the two battery rebates and the Federal solar rebate program below.
WA Residential Battery Scheme
The WA Government’s Residential Battery Scheme offers battery rebates and zero-interest loans to help households cover the cost of a home battery system.
The WA Government’s Battery Rebate:
- offers rebates of up to $1,300 for Synergy customers. That’s $130 per kWh of your new home battery’s capacity, up to 10kW.
- cannot be applied retrospectively to previously installed batteries.
- requires your home battery to be connected to a Virtual Power Plant (VPP).
- only includes batteries on Synergy’s Supported Solutions List.
The WA Government’s zero-interest loans are administered by Plenti, the scheme’s financial partner. The loans:
- have a loan value of up to $10,000
- are available to WA households with a combined income of less than $210,000/year
- have repayment terms between 3 and 10 years
- require your home battery to be connected to a Virtual Power Plant (VPP)

We’ll check with you if you want to apply for the WA Government battery rebate, and zero-interest loan, and include all the information in your quote.
Federal Cheaper Home Batteries Program
The Federal Government’s Cheaper Home Batteries Program helps reduce the upfront cost of installing a home battery. It’s delivered through the Government’s Small-scale Renewable Energy Scheme and is calculated based on the battery’s capacity in usable kilowatt-hour (kWh). It works by creating Small-scale Technology Certificates (STCs) for batteries and using those to reduce the cost of the battery.
To be eligible for the Cheaper Home Batteries Program, you must:
- have your home battery paired with rooftop solar panels (panels can be new or existing)
- install a battery and an inverter that’s on the Clean Energy Council’s approved list. All Kleenheat Spark battery packages are eligible for this rebate.
- have your battery installed by an accredited installer
The program is designed to phase out over time, with the rebate discount set to decrease gradually until the program ends in 2030. You can only apply for the rebate once.
To learn more, please visit the Federal Cheaper Home Batteries Program website.
Small-scale Renewable Energy Scheme (SRES)
This federal scheme provides Small-scale Technology Certificates (STCs) that lower the upfront cost of your solar panels and are calculated based on your system size, location and installation date.
How the WA and Federal rebates combine for bigger savings
The WA and Federal rebates are designed to work together and allow eligible households to significantly reduce the upfront cost of installing a home battery.
Here’s an example of how combining the rebates could reduce your payback period (the time it takes to earn back your initial investment):
- Typical battery cost: Approximately $11,000 for a 6.6 kW system with a 10kWh battery
- Combined rebates: Approximately $5,500 ( with WA battery, Federal battery and Federal solar rebates)
- Annual savings: around $2,500 from reduced grid reliance and VPP participation
- Estimated payback period with rebates: around 4.2 years
- Estimated payback period without rebates: Payback would stretch to about 10 years
