Finance options
Spread the cost — interest-free
Eligible WA households can access up to $10,000 in no-interest finance for a home battery, repaid over 3–10 years. Here's how it works and exactly what it costs per month.
$10,000 interest-free
Borrow $2,001–$10,000 at 0% interest through the WA Residential Battery Scheme loan, delivered by Plenti — you only ever repay what you borrow.
$0 upfront, fast approval
No deposit needed to get started, with applications typically approved in 24–48 hours so your install isn't held up.
Flexible terms
Choose a repayment term from 3 to 10 years with no early-repayment fees — pay it off faster whenever you like.
Repayments
What it costs per month
0% interest, so the monthly is simply what you borrow divided by the term.
