Up to $7,500 off a home battery - when you stack the WA scheme with the federal Cheaper Home Batteries Program. We'll show you your exact number in 30 seconds. No installer spin.
The federal rebate is around $330/kWh in 2026, dropping to ~$260/kWh in 2027. For a typical 13.5 kWh battery, that's about $945 less rebate if you wait a year. The WA state scheme is also capped at 100,000 households — first come, first served.

National sites treat WA as a footnote and ignore the Synergy vs Horizon split. Local installer sites pretend to be reviewers. We're independent - we don't install batteries, we just help you pick.
We don't install batteries. We rank installers on accreditation, reviews and price - not who pays us most.
Built for the Synergy and Horizon Power split. The maths is different - we model both correctly.

View profileIf you're a Synergy customer (Perth metro + south-west), up to $5,000. If you're on the Horizon Power network (Pilbara, Kimberley, Mid West, Goldfields-Esperance), up to $7,500. That's before the federal Cheaper Home Batteries Program stacks on top.
Yes. They're designed to stack. The federal Cheaper Home Batteries Program (started 1 July 2025) discounts at point of sale; the WA state rebate is applied separately by your accredited installer.
No - but you'll get the most value if you have at least a 5–6 kW system. Without solar, a battery still earns money on time-of-use tariffs but the payback is slower.
The scheme runs first-come, first-served. Uptake is steady, not panic-level - but applications need to be lodged through your installer, and slots aren't reserved until that happens.
A small sample of feedback from homeowners who used the calculator and got quotes through us.
"Ran the calculator, saw I was eligible for around $10k off, got three quotes within a day. Picked the one that explained the maths best. Battery was installed three weeks later."
"Honest comparison without the usual installer spin. The Synergy vs Horizon explainer cleared up months of confusion in five minutes."
"Calculator showed me a 5-year payback so I went for it. Year one bills are already 60% lower than the same period last year."
"Was about to sign with the first installer who knocked on the door. Glad I checked here first - the second quote saved me $1,800 on the same setup."
"No pressure tactics. Three installers contacted me, all SAA-accredited, all with proper quotes within 48 hours. Compared them side by side and picked."
"New build, full solar + battery package quoted by three installers. The advice on inverter pairings saved us from a bad combination - wouldn't have known to ask."
