How to Apply for the WA Battery Rebate 2026: Step-by-Step Guide

Important: You Cannot Apply Directly

Unlike some government rebate programs where you submit an application yourself, the WA Residential Battery Scheme works through approved vendors. Your installer submits the rebate and loan applications on your behalf. This means your first step is choosing the right approved vendor — not filling out a government form.

Step-by-Step Application Process

Step 1: Check Your Eligibility

Before getting quotes, confirm you meet all eligibility requirements:

• Property ownership: You must own the property (owner-occupier). Renters and landlords are not eligible.
• WA location: The property must be in Western Australia on the Synergy network (SWIS).
• No previous battery rebate: You cannot have received a battery rebate through this scheme before. One rebate per property.
• For the interest-free loan: Combined household income must be under $210,000 per year. The rebate itself has no income limit.

Step 2: Get Quotes from Approved Vendors

Only approved vendors can submit rebate applications. The list of approved vendors is maintained by Plenti (the scheme administrator) and available on their website. When getting quotes:

• Get at least 2–3 quotes from different approved vendors
• Ensure the quoted battery is on Synergy's Supported Solutions List (SSL) — this is a separate requirement from the vendor being approved
• Ask for itemised quotes showing the rebate and loan amounts separately
• Check that the quote includes installation, electrical work, and Western Power connection application fees

Step 3: Choose Your Vendor and Sign the Agreement

Once you've selected a vendor and agreed on the battery system, your vendor will:

• Submit the rebate application to the scheme on your behalf
• If you're applying for the interest-free loan, initiate the Plenti loan application
• Handle all required paperwork and approvals

Step 4: Plenti Loan Assessment (If Applicable)

If you're applying for the interest-free loan, Plenti will contact you directly to complete the loan assessment. This involves:

• Identity verification (100 points of ID)
• Income verification (combined household income under $210,000)
• Credit check
• Choosing your repayment term (3 to 10 years)

The loan assessment is typically completed within a few business days. Approval is not guaranteed — standard responsible lending criteria apply.

Step 5: Installation

Once the rebate and loan (if applicable) are approved, your vendor schedules the installation. This typically involves:

• Pre-installation site assessment
• Battery and inverter installation (usually 1 day)
• Electrical connection and testing
• Western Power connection application and approval
• System commissioning and handover

Step 6: VPP Enrollment (Mandatory)

After installation, your battery must be enrolled in a Virtual Power Plant (VPP) program. This is a mandatory requirement to receive the rebate. Your installer will typically assist with enrollment. Current VPP options include:

• Synergy Battery Rewards: Pays up to 70c/kWh during grid demand events. The most common choice for Synergy customers.
• Other approved VPP programs as listed on the scheme's website

What You Need for Your Application

Common Questions

Can I choose any battery?

No. The battery must be on Synergy's Supported Solutions List (SSL). Most major brands including Sungrow, BYD, Huawei, and GoodWe are listed. Tesla Powerwall is currently not on the SSL, which means it doesn't qualify for the WA rebate or interest-free loan.

What if I already have a battery?

Batteries installed before 1 July 2025 are not eligible for the scheme. If you installed after that date without claiming the rebate, check with an approved vendor whether a retrospective application is possible.

Can I get the rebate without the loan?

Yes. The rebate and the interest-free loan are separate components. You can claim just the rebate and pay the remaining balance in cash or through your own financing arrangement.

How long will the scheme last?

The WA Residential Battery Scheme is funded for up to 100,000 rebates. At current uptake rates, the scheme is expected to remain open for several years. However, rebate values may step down over time, so earlier applications may receive higher rebates.

Watch Out For

• Unapproved vendors: Only buy through an approved vendor listed on the Plenti website. Purchasing from a non-approved installer means you cannot claim the rebate.
• High-pressure sales tactics: Consumer Protection WA has warned about aggressive marketing around the scheme. Take your time, get multiple quotes, and don't be rushed into signing.
• Non-SSL batteries: Some vendors may push premium batteries that aren't on the SSL. This locks you out of the WA rebate and interest-free loan.
• Hidden costs: Ensure your quote includes all costs — switchboard upgrades, meter changes, and Western Power application fees should be itemised.
