The federal battery rebate, delivered through the Cheaper Home Batteries Program, gets smaller on 1 January 2027. It doesn’t end. That difference matters, because battery sellers lean heavily on cold calls and door knocks. An ACCC review published in July 2026 found solar panels and energy devices were among the products Australians most often bought through unsolicited selling. Two in three people approached this way said they felt pressured, and some salespeople misrepresented whether customers qualified for government programs.
Before the last battery rebate step-down on 1 May 2026, the Clean Energy Regulator (CER) publicly warned retailers that deceptive or misleading behaviour would be reported to fair trading bodies.
With the next step-down less than three months away, this guide explains what’s actually changing, how to tell an honest deadline from a fake one, and what to do if you’ve been rushed into signing.
Quick summary
- The battery rebate drops on 1 January 2027 but continues until 31 December 2030.
- Real step-downs happen only on 1 January and 1 July. Any other “deadline” is a red flag.
- If you signed after a cold call or door knock, you generally have 10 business days to cancel.
When does the battery rebate step down?
Both federal rebates run through the same scheme, the Small-scale Renewable Energy Scheme, and both shrink on a published schedule until the end of 2030. Neither ends before then.
| Solar panels | Home batteries | |
| How often it steps down | Once a year, on 1 January | Every six months, on 1 January and 1 July |
| Next step-down | 1 January 2027 | 1 January 2027 |
| Last installs eligible | 31 December 2030 | 31 December 2030 |
Three details matter more than most salespeople let on.
It’s the install date that counts, not the signing date. The CER says the rebate is set by when the system is installed, not when you sign the contract. A deal signed in December but installed in January gets January’s rebate.
Big batteries get less per kWh. Since 1 May 2026, the battery rebate is tiered. The first 14 kWh of usable capacity earns the full rate, every kWh from 14 to 28 earns 60%, and every kWh from 28 to 50 earns 15%. A quote that applies the full rate to a 30 kWh battery is overstating your discount.
Each step is a trim, not a cliff. A step-down reduces the number of certificates your system earns. It doesn’t remove the rebate. You can check the exact current figure for your system with the CER’s battery STC calculator.

What the regulator says
Ahead of the May 2026 step-down, the Clean Energy Regulator told retailers not to rush installations to beat the change. As CER Executive General Manager Carl Binning put it: “Installers are being urged to do it once and do it well.” (Clean Energy Regulator)
Expert tip
Get the install date in writing, not just the contract date. Ask the retailer to state on the quote who pays the difference if the install slips past a step-down.
How to tell a real rebate deadline from a fake one
Not every “book before January” message is a scam. The step-downs are real, so an installer who says “if we install before 1 January, your rebate is about $X higher” is telling you something true and useful. The problem starts when the urgency is bigger than the facts.
| Honest | Manufactured |
| “The rebate drops on 1 January.” | “The rebate ends on 1 January.” |
| Names a real step-down date (1 January or 1 July) | Names a date that isn’t a step-down, or no date at all |
| Tells you the dollar difference for your system | Talks about “losing thousands” without showing the maths |
| Only promises a pre-deadline install if they can actually deliver it | Promises an install date to close the sale, then misses it |
| Gives you time to compare quotes | Pressures you to sign today |
A useful test: ask the salesperson to put the deadline and the dollar difference in writing on the quote. Someone giving you honest information won’t mind.
Expert tip
Ask for two prices on the same quote: one for installing before the step-down and one for after. An honest installer can work this out in minutes, and it shows you exactly what waiting would cost.
Red flags in battery rebate sales pitches
- The rebate is described as “ending”, “closing” or “running out” before the end of 2030.
- The deadline isn’t 1 January or 1 July.
- The quote shows a rebate figure but not how it was calculated.
- A large battery (over 14 kWh) is quoted at the full per-kWh rebate rate.
- You’re asked to sign on the spot, or the “special price” expires within hours.
- The salesperson guarantees an install date before the step-down but won’t write it into the contract.
- The offer arrived through a cold call, door knock, or social media ad, and the company is hard to look up.
- You’re told the battery or system is “free” thanks to the rebate.
Expert tip
Before responding to a rebate offer from a cold call or social media ad, look up the business on the government’s ABN Lookup site. A company with no history, or a name that doesn’t match the ad, is a reason to walk away.
How to check a rebate claim yourself
It takes about ten minutes to check a quote against official sources.
- Run the numbers. Enter your battery size and planned install date into the CER’s battery STC calculator and compare the result with the rebate on your quote.
- Check the dates. Confirm the next step-down date on the Clean Energy Regulator’s website rather than taking the salesperson’s word for it.
- Check the installer. Rebates only apply when an accredited installer installs an approved product. Look up the installer’s accreditation and the battery model before you sign.
- Get a second quote. If one quote is far cheaper or the rebate is far bigger than the others, find out why.
- Get it in writing. The quote should show the total price, the rebate amount, the install date, and what happens to the price if the install slips past a step-down.
Expert tip
Ask for the battery’s usable capacity, not just its total capacity. The rebate tiers are based on usable kWh, so a quote built on the bigger number can overstate your discount.

Can you cancel a battery contract after signing?
You may be able to cancel. If the sale came from a door knock, a phone call or another approach you didn’t ask for, it counts as an “unsolicited consumer agreement” under Australian Consumer Law. That gives you a 10-business-day cooling-off period to change your mind, and the seller must refund anything you’ve paid if you cancel. The right doesn’t apply if you contacted the company yourself, for example through its website or a showroom.
The cooling-off rules also expose a common pressure tactic. During those 10 business days, the seller isn’t allowed to provide services, supply goods worth more than $500, or take payment. So a door-to-door seller who promises to install your battery within a few days, to beat a step-down, is offering something the law doesn’t allow. If the seller breaks these rules or fails to tell you about your cooling-off rights, the cooling-off period can extend to as long as six months.
Expert tip
Read the sales agreement for the cooling-off notice and cancellation form. The ACCC found only 63% of people who bought through unsolicited selling were told about their cooling-off rights, so don’t assume a salesperson will mention it.
Where to report it
- Misleading advertising or sales conduct: the ACCC. The ACCC investigates businesses but doesn’t resolve individual disputes.
- Help with your own dispute: your state or territory consumer protection agency, such as NSW Fair Trading, Consumer Affairs Victoria or Consumer Protection WA.
- Scams, such as fake rebate offers asking for upfront payment: Scamwatch.
- Problems with a rebate-eligible installation: the Clean Energy Regulator, which can investigate installers and retailers and remove them from the scheme.
Frequently asked questions
Is the federal battery rebate ending on 1 January 2027?
No. On 1 January 2027, the battery rebate steps down, so eligible batteries earn fewer certificates and a smaller discount. The Cheaper Home Batteries Program continues, with further reductions every six months, until 31 December 2030. Anyone claiming the rebate ends in January is wrong.
Is the rebate based on when I sign or when the battery is installed?
The installation date decides your rebate, not the date you sign the contract. If you sign in December but the battery is installed in January, you get January’s lower rate. Ask your retailer to confirm the install date in writing and say who covers any price difference.
How much rebate do I get for a large battery?
Since 1 May 2026, the rebate is tiered by usable capacity. The first 14 kWh earns the full rate, capacity from 14 to 28 kWh earns 60%, and capacity from 28 to 50 kWh earns 15%. Use the Clean Energy Regulator’s STC calculator to check the figure for your battery.
Can I cancel a battery contract after signing?
If the sale came from a door knock, cold call or other approach you didn’t ask for, you generally have 10 business days to cancel under Australian Consumer Law, and the seller must refund your money. This right doesn’t automatically apply if you contacted the business yourself.
Where can I report misleading battery rebate claims?
Report misleading advertising or sales conduct to the ACCC, and get help with your own dispute from your state or territory consumer protection agency. Report scams to Scamwatch. Problems with a rebate-eligible installation can go to the Clean Energy Regulator, which can investigate retailers and remove them from the scheme.
Key takeaways
- The federal battery rebate steps down on 1 January 2027 and continues until 31 December 2030.
