WA Battery Rebate 2026 Eligibility: Who Can Apply for the Residential Battery Scheme?
If you are researching the WA battery rebate in 2026, the first thing to know is that eligibility is more specific than many people expect. Western Australia's Residential Battery Scheme is open to eligible Synergy and Horizon Power customers, but applicants, properties, products, and even installation timing all have to meet the scheme rules. ([Western Australian Government][1])
At the applicant level, you must be an Australian permanent resident, 18 years or older, a Synergy or Horizon Power customer, able to verify your identity, and able to show evidence of a supply agreement for an eligible battery purchase. ([Western Australian Government][2])
Your property also needs to qualify. According to the WA Government, the home must be in Western Australia, be a standalone home or unit-titled property, and be owned or rented by you. If you rent, landlord consent is required. The property must be used mainly for residential purposes, and it must have a reliable internet connection because the system needs to support testing and participation requirements. ([Western Australian Government][3])
The battery itself must meet scheme conditions too. The government says eligible systems include new, replacement, or additional batteries with usable capacity between 5kWh and 10kWh. The battery must be on the Clean Energy Council approved list and also satisfy the relevant technical and compliance rules for Synergy or Horizon Power. ([Western Australian Government][3])
There is also a date rule that catches some homeowners out: batteries installed before 1 July 2025 are not eligible for the rebate or loan funding. So if a system was already installed before the scheme start date, it does not qualify retrospectively. ([Western Australian Government][3])
One of the biggest eligibility conditions is Virtual Power Plant participation. Households are required to join a VPP to access the rebate or no-interest loan. Synergy customers can use Synergy's own VPP product or an eligible alternative product that meets the published criteria, while Horizon Power customers must join Horizon Power's VPP product. ([Western Australian Government][3])
For many households, the money matters most. The WA Government says eligible rebate amounts are up to $1,300 for Synergy customers and up to $3,800 for Horizon Power customers under the WA scheme itself. On a 10kWh battery, the government states that this can become a combined rebate of up to $5,000 for Synergy customers and up to $7,500 for Horizon Power customers when combined with the Federal Cheaper Home Batteries Program. ([Western Australian Government][3])
There is also a no-interest loan option. Eligible households can borrow $2,001 to $10,000, with terms from 3 to 10 years, and no interest. To qualify for the loan, household gross annual income must be under $210,000, and applicants are subject to credit checks and prudential lending requirements. ([Western Australian Government][2])
The short version is this: you are most likely to qualify if you are a WA homeowner or renter on the Synergy or Horizon network, you are installing a new approved battery sized between 5kWh and 10kWh, and you are willing to join an approved VPP. ([Western Australian Government][2])
