Is my new battery actually installed safely? Verify it yourself — but don't panic.
A rebate approval and an accredited installer do not guarantee a compliant install — the Clean Energy Regulator’s own inspections show most flagged installs fell short of the standard. But there’s an honest distinction the fear-web skips: the large share flagged were substandard but safe to keep operating, and only a tiny fraction were unsafe. Here’s a homeowner visual check you can do today, and your right to a free fix if something looks off.

Was your battery installed safely?
Probably fine — but worth a check.
The honest short answer: a rebate and an accredited installer are not proof of a compliant install — but most flagged problems are paperwork-and-labelling faults you can keep living with while they’re fixed, not immediate danger.
Here’s the frame nobody selling you a battery mentions. When the Clean Energy Regulator (CER) inspects battery installs done under the rebate, a majority come back flagged — but the honest split matters enormously. As at 8 June 2026, across 2,642 inspections of installs from 1 July 2025 onward, the CER found roughly 62% ‘substandard’, about 37% ‘adequate and safe’, and just 0.83% (around 22 installs) ‘unsafe’ (source: CER inspection results report). These are cumulative figures that shift as the sample grows — confirm the current numbers at cer.gov.au.
The word that does the heavy lifting is substandard. The CER’s own report states substandard installs ‘were safe to remain in operation’ — it means a workmanship or compliance failing (usually a labelling or configuration miss), not immediate danger. So the honest verdict is amber: don’t assume your install is perfect just because the rebate cleared, but don’t panic either. Do the visual check below, and if anything looks off, you have a right to a free fix.
Substandard vs unsafe
they are not the same thing.
Fear-selling blurs these two into ‘most installs are dangerous’. They aren’t. Here’s what each category actually means, straight from the regulator’s findings.
Adequate and safe
More than a third of inspected installs were found fully adequate and safe — no action needed. This is what a compliant install looks like, and plenty of installers deliver it.
Substandard but safe to operate
The big category. The CER says these ‘were safe to remain in operation’ — the faults are dominated by labelling (missing or wrong warning labels, backup-circuit labels, emergency-services signage), plus incorrectly configured or missing RCDs and insufficient mechanical or fire protection. Real failings that must be rectified — but not an immediate danger.
Unsafe (about 22 installs)
The sub-1% that involved genuine risk. The issues were wiring-related: loose connections in pre-assembled systems showing signs of heat, pre-assembled electrical work not to Australian standards, and neutral continuity not maintained on backup circuits. This is the category worth checking for and acting on quickly.
A homeowner visual check
look, don't touch.
You can do all of this with your eyes and a phone torch. Do not open, poke or test any wiring or connection yourself — anything electrical is for a licensed electrician or your installer. This is a look-only check.
Because labelling is the single biggest thing the CER flags, most of a useful homeowner check is simply reading what should be on and around your battery. Working from the CER and Solar Victoria audit checklists, here’s what a compliant install should show:
- Warning labels are present and readable — not faded, peeling or missing.
- A shutdown-procedure label is visible, so anyone can see how to safely power the system down.
- Backup-circuit labels are correct — if you have backup, the circuits it feeds should be clearly identified.
- Emergency / energy-storage signage is correctly placed (this is what emergency services look for).
- The battery enclosure is intact and properly mounted — no gaps, damage, or a unit that moves.
- Wiring is enclosed in conduit and secured — no loose cables draped or hanging.
- Isolators and switches are labelled and accessible — you can reach and identify them.
- An RCD is present and labelled at the switchboard.
- No exposed connections or terminals, and visible earthing where cabling enters enclosures.
If several of these are missing or wrong, that’s a substandard-labelling pattern — annoying, fixable, and not usually an emergency. Note what you find with photos, and raise it with your installer (see your rights below).
A rebate isn't an inspection
and accreditation isn't a guarantee.
The seller web implies ‘rebate approved + accredited installer = safe’. Here’s why that isn’t how it works — and why doing your own visual check is worth ten minutes.
Two things get quietly conflated in a sales pitch. First, an eligible battery install must meet AS/NZS 5139:2019, and only trained, licensed installers accredited by Solar Accreditation Australia (SAA) using CEC-approved products can complete or supervise it (accreditation moved to SAA — the CEC now maintains the approved-product list, not the installer accreditation). That’s a real bar. But it’s a bar the CER’s inspection results show a majority of installs still trip on.
Second, and more importantly: a rebate approval does not mean your install was inspected. CER post-install inspections are a statistically significant sample only, they are voluntary, and they can only proceed with the homeowner’s written consent (source: CER inspections). So most homeowners will never be inspected. If yours wasn’t — which is likely — nobody independent has checked the workmanship. That’s exactly why a five-minute visual check on your side is worth doing, whatever the paperwork says.
The reassuring part: where the CER does find non-compliance, it’s the accredited installer or designer who is responsible for returning to rectify it — at no cost to you.
If something looks off
you're entitled to a free fix.
You don’t have to argue the technical detail. Any non-compliance is the installer’s responsibility to put right. Here’s the escalation ladder — and the body that isn’t the right one.
Your installer or retailer
Contact the retailer or installer who supplied the system and ask them to rectify it. Put it in writing, attach your photos, and ask for a re-check on completion. This resolves most issues — the accredited installer is required to return and fix non-compliant work.
State Fair Trading
If it’s unresolved, lodge a complaint with your state or territory Fair Trading or consumer-protection agency. This is your Australian Consumer Law backstop for a supplier who won’t make good.
Solar Accreditation Australia
For installation-quality concerns, lodge with Solar Accreditation Australia (SAA), which enforces rectification by accredited installers and can act on their accreditation.
Verify, don't spiral
this is a fixable problem.
The scare framing turns a labelling statistic into a reason to fear your own home. The measured version is more useful — and calmer.
It’s worth restating plainly, because a lot of content online won’t: under the CER’s own data, the overwhelming majority of flagged installs are safe to keep operating while a workmanship fault — usually labelling — is corrected. The genuinely unsafe share sits under 1%. That’s not a reason to rip your battery out or lie awake; it’s a reason to spend ten minutes reading your labels and looking at your enclosure, and to make one phone call if something’s wrong.
And a note on timing, since it gets weaponised too: the Cheaper Home Batteries Program runs with gradual STC step-downs toward 2030 — there’s no deadline cliff forcing you to rush a rushed install. If you’re still choosing an installer, the best safety move happens before you pay: our guide on how to check a solar installer before you hand over a deposit is where compliant installs really start. And if you want to know what a good install day looks like, see what to expect on install day.
So — should you be worried
about your battery install?
Here’s the call we’d give a friend who just had a battery fitted, in order.
First, do the visual check — labels readable, backup-circuit and emergency signage present, enclosure intact and mounted, wiring in conduit, isolators labelled, no exposed terminals, no heat marks. Ten minutes, torch only, nothing touched. If it all looks right, you’re very likely in the ‘adequate and safe’ or an easily-fixed ‘substandard-labelling’ camp — no drama. If labels or configuration look wrong, photograph it and ask your installer to rectify in writing; escalate to state Fair Trading, then Solar Accreditation Australia, if they stall — it’s their job to fix, free. If you see heat marks, scorching, a burning smell or loose terminals, don’t touch it — isolate if you safely can and call a licensed electrician or your installer today. What we’d urge against is either extreme: assuming the rebate proves your install is perfect, or reading a labelling statistic as a reason to fear your home. Verify, then act at the right pace.
Battery install safety
your questions, answered.
No. A Cheaper Home Batteries rebate being approved does not mean anyone independent inspected your install. The Clean Energy Regulator's post-install inspections are a statistically significant sample only, they are voluntary, and they can only go ahead with the homeowner's written consent, so most homeowners are never inspected. An accredited installer using approved products must meet AS/NZS 5139:2019, but the regulator's own results show a majority of inspected installs still fall short, usually on labelling. That is exactly why a quick homeowner visual check of labels, enclosure and isolators is worth doing regardless of what the paperwork says. Confirm current details at cer.gov.au.
As at 8 June 2026, across 2,642 inspections of installs from 1 July 2025 onward, the Clean Energy Regulator found roughly 62% substandard, about 37% adequate and safe, and 0.83% (around 22 installs) unsafe. Crucially, the regulator states the substandard installs were safe to remain in operation, meaning a workmanship or compliance failing such as incorrect labelling, not immediate danger. The unsafe category involved wiring faults like loose connections showing heat. These are cumulative figures that shift as more inspections are done, so treat them as a snapshot and confirm the latest numbers at cer.gov.au before relying on them.
Substandard is the Clean Energy Regulator's term for an install that fails part of the standard but, in its own words, is safe to remain in operation. It is a workmanship or compliance failing, not immediate danger. The substandard findings are dominated by labelling problems, such as missing or incorrect warning labels, backup-circuit labels and emergency-services signage, plus incorrectly configured or missing RCDs and insufficient mechanical or fire protection. These need to be rectified by your installer, but you can generally keep using the system while that is arranged. The genuinely unsafe category, which involves wiring faults, is under 1% of inspections and is the one to act on quickly.
Plenty, using only your eyes and a torch. Check that warning labels are present and readable, that there is a visible shutdown-procedure label, that backup-circuit labels and emergency energy-storage signage are correctly placed, that the battery enclosure is intact and properly mounted, that wiring is enclosed in conduit and secured, that isolators and switches are labelled and accessible, that an RCD is present and labelled, that there are no exposed connections or terminals, and that earthing is visible. Do not open, poke or test anything electrical yourself, as that is for a licensed electrician or your installer. If you see heat marks, scorching or smell burning, isolate if safe and call a professional immediately.
Any non-compliance identified is the responsibility of the accredited installer or designer, who is required to return and rectify it at no cost to you. The pathway is: first, contact the retailer or installer who supplied the system and ask them in writing to fix it, attaching photos. If that is unresolved, lodge a complaint with your state or territory Fair Trading or consumer-protection agency. For installation-quality concerns specifically, you can also lodge with Solar Accreditation Australia, which enforces rectification by accredited installers. The energy ombudsman is not the right body for install workmanship, as it handles billing, metering and connection matters. If your installer has closed down, a warranty pathway may still exist through the manufacturer.
Battery installers are now accredited by Solar Accreditation Australia (SAA), not the Clean Energy Council directly, though the CEC still maintains the approved-product list. You can check an installer's current accreditation status through Solar Accreditation Australia. This matters because your rebate eligibility and your right to free rectification both rely on the install being completed or supervised by an SAA-accredited installer using CEC-approved products, meeting AS/NZS 5139:2019. If you are still choosing an installer, verifying accreditation before you pay a deposit is the single most effective thing you can do to avoid a substandard install, since the regulator's inspections show most flagged faults trace back to workmanship at install time.
