The Cheaper Home Batteries Program, honestly.
The federal rebate takes around 30% off an eligible battery — real money, honestly explained. Here's exactly how it works, who's eligible, and why "the rebate is ending, act now" is a sales tactic, not the truth. No urgency games.

What is the Cheaper Home
Batteries Program, in one honest paragraph?
It's the federal government's battery rebate. It takes around 30% off the installed cost of an eligible battery, delivered through tradeable certificates your installer applies at the point of sale — so you see it come off the price, not claim it back yourself.
The Cheaper Home Batteries Program (CHBP) is the federal scheme that cuts around 30% off the installed cost of an eligible home battery. Instead of a flat cash grant, the discount is delivered as tradeable STCs (small-scale technology certificates). Your accredited installer creates and sells those certificates and passes the value through as a reduction on your quote — you do not claim it yourself.
Two things are worth knowing straight away, because they're exactly where sales pressure creeps in. First, there is no fixed dollars-per-kWh figure — the STC value floats with the market, so any headline "$X off" number drifts and shouldn't be taken as a promise. Second, the program steps down gradually, roughly every six months, out to about 2030 — it does not end in a sudden July-2026 cliff. So "the rebate is ending, buy now" is a sales tactic, not the truth.
The rest of this page walks through how the discount is calculated, who's eligible, how it's applied, what it stacks with, and — honestly — when it's worth waiting. If you'd rather just see what you'd qualify for, start with the rebate checker or the fuller rebates & incentives page.
How does the ~30% discount
actually work?
The rebate is measured in STCs per kilowatt-hour of usable capacity, and it's tapered so the biggest systems earn proportionally less. Here are the moving parts, plainly.
~6.8 STCs per kWh
From 1 May 2026, the program pays about 6.8 STCs per kWh of usable capacity. That rate is what drives the roughly 30% headline discount — but it steps down over time (more on that below).
The value floats
Each STC trades on an open market — roughly $37 to $39 at the time of writing. Because the price moves, there's no fixed dollars-per-kWh. Anyone quoting a precise "$X per kWh" as gospel is guessing at a moving number.
It's tapered by size
You get full value on the first 14 kWh of usable capacity, 60% on the portion above 14 up to 28 kWh, and 15% above 28 up to 50 kWh. So a very large battery earns less per kWh than a modest one.
Eligible 5–100 kWh
Eligible batteries run from 5 to 100 kWh, with the certificates paid on the first 50 kWh of usable capacity. Most homes sit well inside this range — the taper means oversizing rarely pays for itself.
Applied at point of sale
Your installer assigns and sells the STCs and passes the value through as a discount on your installed price. You don't lodge a claim — the saving shows up as a lower quote, not a cheque you chase.
"~30% off" not "$X off"
Because the certificate price and your exact system both move the total, the honest way to describe it is around 30% off, then a real quote for the dollar figure. We won't print a fixed number here that would only mislead.
Am I eligible for the
Cheaper Home Batteries Program?
Eligibility is mostly about the battery and the install, not your income. If your battery is the right size, installed to standard by an accredited installer and has something to charge it, you're almost certainly in.
The federal program is refreshingly simple on eligibility compared with many state schemes:
- Battery size 5–100 kWh. Eligible systems run from 5 to 100 kWh of usable capacity, with the STC discount paid on the first 50 kWh. Most household batteries sit comfortably inside this band.
- Accredited install, approved product. The battery must be on the approved product list and installed by an accredited installer to the relevant standard — which is exactly why we work only with SAA-accredited installers.
- Paired with solar. A battery is meant to store cheap daytime energy, so it's normally installed with new or existing solar. A battery with nothing to charge it is just an expensive box.
- No federal means test. Unlike some state programs, the federal CHBP itself isn't income-tested, and it's available Australia-wide.
Because the discount is delivered as STCs your installer claims and passes on, you don't lodge anything yourself. Conditions can change, so the honest step is to confirm your battery, size and site qualify before you sign — which is part of what a free assessment checks.

How is the discount
actually applied to my quote?
You don't claim it — your installer does, and it comes off the price up front. Here's the chain, so you know exactly what should appear on your quote.
When your eligible battery is installed, it earns a set number of STCs based on its usable capacity and the current rate. Your accredited installer creates those certificates, sells them on the STC market, and passes the value through as a reduction on your installed price. So the roughly 30% saving shows up as a lower quote, not a rebate cheque you apply for afterwards.
Because the certificate price floats, the exact dollar value can differ slightly between quotes and over time — which is one more reason the discount is honest to describe as "around 30% off" rather than a fixed figure. Two practical asks that protect you:
- Have the STC discount itemised on your quote so you can see exactly how much has come off, rather than a single "after rebate" number with the workings hidden.
- Check the installer is accredited, because the certificates are only valid if the install meets the program's requirements. If an installer can't clearly explain the STC line, that's a flag.
This is also why we won't quote you a fixed "$X after rebate" here: it would be an estimate that drifts. The honest number is a real quote for your home. You can read the fuller mechanics on our rebates & incentives page, or weigh a battery's overall value in our guide to whether a home battery is worth it in 2026.
Is the battery rebate ending soon?
(No — and here's the proof.)
This is the single most-misused fact in battery sales. The program steps down gradually, roughly every six months, out to about 2030. It does not end in a cliff — so "act now or lose it" is pressure, not truth.
Here's the actual timeline. The Cheaper Home Batteries Program launched on 1 July 2025. It reduces in small, scheduled steps rather than switching off:
- Now (from 1 May 2026): about 6.8 STCs per kWh of usable capacity.
- The next step — 1 January 2027: the rate reduces to about 5.7 STCs per kWh. Modest, not a collapse.
- Then, roughly every six months after that, in further small steps, tapering out to about 2030.
Notice what that means. Waiting a few months changes your discount only slightly — not dramatically, and certainly not "now or never". There is no July-2026 cliff, despite what an urgency-driven pitch might imply. So a looming deadline is almost never a good reason to rush a battery that doesn't fit your home.
Put simply: if a battery is a good fit, the maths already works today, and a small future step-down doesn't change that. If it isn't a good fit, a deadline doesn't make it one. Anyone telling you to buy today or lose the rebate is selling urgency, not helping you decide. That's exactly the kind of pressure our honest energy advisor, Jouli, is built to defuse — and you can see how often our advice is "not yet" on our public honesty record.
Does the federal rebate stack
with state incentives?
Often yes — the federal CHBP can stack with some state incentives, but it depends where you live and what's current. Here's how to think about it without getting talked into strings that aren't worth it.
The federal STC discount is designed to sit alongside certain state programs rather than replace them. A clear current example is the New South Wales VPP incentive, which can be combined with the federal CHBP if you join an eligible virtual power plant. State programs open, close and change eligibility over time, though, so the honest answer for your address is to check what's live right now rather than rely on a general rule.
Two honest caveats before you chase every stack:
- A stack sometimes comes with conditions. Joining a VPP, for instance, can mean letting a provider dispatch your battery at certain times. That may be worth it — or it may not suit how you use your stored energy. We'd rather tell you a stack isn't worth the strings than sign you up for one that is.
- The state landscape shifts. Several older state battery schemes have closed, and what's available in your state today may differ from a year ago. Don't assume a scheme mentioned elsewhere online is still open.
The fast way to see your real options is the rebate checker, with the fuller detail on our rebates & incentives page. A free assessment then confirms exactly which incentives apply to your home, battery and state — and whether stacking them actually improves your payback.
When is it smarter to
wait or buy smaller?
The rebate is generous, but it doesn't make every battery a good buy. Because the program steps down only gradually, you can decide on fit — not fear. Here are the clear cases where waiting or going smaller is the honest move.
Payback outlasts the warranty
If the price after the rebate would still take longer than the battery's warranty and throughput life to pay back on your usage, don't buy that one yet. A slightly larger rebate on a battery that pays back too late is still a loss.
No solar or no daytime surplus
A battery needs cheap daytime energy to store. If you don't have solar yet, or your panels don't produce a real surplus, sort that first — the rebate doesn't help a battery that has nothing cheap to charge it.
The taper is against a big unit
Because the STC rate tapers above 14 kWh, an oversized battery earns less per kWh and often sits half-used. A smaller unit sized to your genuine evening use frequently pays back better.
Your feed-in tariff still pays well
If you're still on a generous feed-in tariff, exporting your surplus may already earn more than storing it would save. When that tariff drops the sums change — but until then, waiting can be smarter, rebate or not.
You're being told "act now"
The next step-down is 1 January 2027 and it's small. If a pitch leans on an imminent deadline to close you today, treat that as a reason to slow down and get a second opinion, not speed up.
You're in a "sun tax" state
Two-way export pricing (the "sun tax") is live in New South Wales and South Australia, which changes the maths on oversizing solar and how you value stored versus exported energy. It doesn't rule a battery out — it just belongs in the calculation.
Which battery should the
rebate go towards?
Once you've decided a battery is worth it for your home, the rebate applies across a wide field of eligible products. There's no universal "best" — the right one depends on your goal. Here's where to compare the real options.
Compare the field
Start with the side-by-side on our compare systems tool, or the honest roundup in the best home battery in Australia for 2026 — framed by goal, not by a single "winner".
Match it to your goal
Backup, tight budget, expandability or matching an existing inverter all point to different picks. The rebate is the same across eligible batteries, so choose on fit, not on which brand shouts loudest about the discount.
Get it costed honestly
A free assessment shows the rebate applied to your actual options, with the STC line itemised — and tells you if a smaller battery, or waiting for the next step, makes more sense for you.
So — should the rebate change your timing?
Here's the recommendation we'd give a friend: let the rebate make a good-fit battery cheaper — but let fit, not a deadline, decide whether and when you buy.
The Cheaper Home Batteries Program is a genuinely good deal — around 30% off, applied straight to your quote, with no claim for you to lodge. But it steps down gradually, not in a cliff, so it should never be the reason you rush. If you have real evening and overnight usage, solar with daytime surplus, a high peak rate and a low feed-in tariff, a battery is likely worth it for you today and the rebate makes now a reasonable time to act. If you're out all day, still on a good feed-in tariff, or looking at a payback longer than the warranty, the honest answer is to wait or buy smaller — and a slightly bigger rebate this year doesn't change that. The only way to know which side of the line you're on is to run your actual numbers.
The Cheaper Home Batteries Program
— your questions, answered.
The federal Cheaper Home Batteries Program takes around 30% off the installed cost of an eligible battery — but there is no fixed dollars-per-kWh figure, so be wary of any site that quotes one. The discount is delivered as tradeable small-scale technology certificates (STCs), and from 1 May 2026 the rate is about 6.8 STCs per kWh of usable capacity. Because each STC floats with the market — roughly $37 to $39 at the time of writing — the dollar value moves with both the STC price and your exact system. It is also tapered: full value on the first 14 kWh of usable capacity, 60% on the portion above 14 up to 28 kWh, and 15% above 28 up to 50 kWh, so the biggest systems earn proportionally less per kWh. Your installer applies the discount at the point of sale, so you see it come off the price rather than claiming it back yourself. The honest way to know your number is a real quote for your home, not a headline dollar figure.
Eligibility is mostly about the battery and the install, not your income. Eligible batteries run from 5 to 100 kWh of usable capacity, with the STC discount paid on the first 50 kWh, and the system must be installed by an accredited installer to an approved standard, typically paired with new or existing solar so there is something to charge it with. There is no means test on the federal program itself, and it is available across Australia. Because the discount is delivered as STCs your installer claims and passes on, you do not lodge anything yourself — the installer handles the paperwork and the rebate comes off your quoted price. Exact conditions can change, so the honest step is to confirm your battery, size and site qualify before you sign, which is part of what a free Mission Green assessment checks. You can also see what else you might stack on our rebate checker.
No — and 'the rebate is ending, act now' is a sales-pressure tactic, not the truth. The Cheaper Home Batteries Program launched on 1 July 2025 and steps down gradually, roughly every six months, through to about 2030 — it does not end in a sudden cliff. The next scheduled step is 1 January 2027, when the rate reduces from about 6.8 to about 5.7 STCs per kWh of usable capacity, not an overnight cut in mid-2026. Each step is modest, so waiting a few months changes the discount only slightly, not dramatically. That means a looming deadline is almost never a good reason to rush a battery that does not fit your home — if it is a good fit the maths already works, and if it is not, a deadline does not change that. Anyone telling you to buy today or lose the rebate is selling urgency, not helping you.
You do not claim it yourself — your installer does, and it comes off the price up front. The discount is delivered as small-scale technology certificates (STCs), which are created when your eligible battery is installed and then traded on the STC market. Your accredited installer assigns those certificates, sells them, and passes the value through as a reduction on your installed price, so the roughly 30% saving shows up as a lower quote rather than a cheque you chase afterwards. Because the certificate price floats with the market, the exact dollar value can differ slightly between quotes and over time, which is one reason the discount is honest to describe as 'around 30% off' rather than a fixed number. The practical upshot for you is simple: ask that the STC discount is itemised on your quote so you can see exactly how much has come off, and make sure the installer is accredited so the certificates are valid.
Often yes — the federal Cheaper Home Batteries Program can stack with some state incentives, though it depends on where you live and which programs are current. A clear example is the New South Wales VPP incentive, which can be combined with the federal STC discount if you join an eligible virtual power plant. State programs open, close and change eligibility over time, so the honest answer for your address is to check what is live right now rather than rely on a general rule. Our rebate checker is a fast first read on what you might qualify for, and a free assessment confirms exactly which incentives apply to your home, battery and state — and whether stacking them actually improves your payback or just adds conditions. We would rather tell you a stack is not worth the strings attached than sign you up for one that is.
Base it on whether a battery fits your home, not on the rebate calendar. Because the program steps down gradually — the next step is 1 January 2027, from about 6.8 to about 5.7 STCs per kWh — waiting a few months only changes the discount slightly, so there is no cliff to beat. The right time to act is when the numbers already work for you: real evening and overnight usage, solar with daytime surplus to charge the battery, a high peak import rate and a low feed-in tariff. The right time to wait is when the payback would run longer than the battery's warranty and throughput life, when you do not yet have solar or enough surplus to charge it, or when your feed-in tariff still pays you well for exports. A slightly larger rebate on a battery that does not suit your home is still a bad buy. A free Mission Green assessment runs your actual usage and tells you honestly whether now, later, or a smaller battery makes more sense.
