Burglar ratings on a safe tell you exactly how long it resists an attack and what dollar value of cash or valuables an insurer will cover inside it — and most Australian buyers have no idea how to read the plate on the door.
- AS/NZS 3809 rates firearm storage by category (A to H); EN 1143-1 rates burglary resistance by grade (0 to VI).
- A safe with no rating plate isn't a rated safe, no matter what the listing calls it — insurers will reject it.
- TDR (torch and drill resistant) ratings sit on top of the base grade for cash-heavy or high-value storage in 2026.
- Match the grade to your insurer's cash and valuables limit before you buy, not after a claim.
- Security Safes stocks Chubbsafes, CMI, Secuguard and Guardall units carrying recognised AS/NZS and EN certifications.
Why this matters
A safe that looks heavy and has a keypad is not automatically a rated safe. Insurers, firearms registries and courts all reference specific testing standards — AS/NZS 3809 for firearm storage in Australia, EN 1143-1 for European burglary-resistance grading, and TDR (torch and drill resistant) for cash and jewellery protection.
Buy against the wrong rating and you get one of two outcomes in 2026: your insurer caps your payout at a few hundred dollars regardless of what you lost, or your firearms licence gets flagged at compliance inspection. Both are avoidable if you read the rating plate correctly before you check out on securitysafes.com.au.
What you'll need
- The product listing or rating plate on the safe (usually inside the door)
- Your insurance policy's cash and valuables limits, or a call to your broker
- Your firearms licence category if the safe is for guns (Cat A, B, C, D or H in most states)
- 15 minutes to cross-check the rating against what you're actually storing
The steps
1. Identify which standard the safe is actually tested to
Many listings say "high security" with no reference to a testing body. That phrase means nothing on its own. Look for AS/NZS 3809 (the Australian standard covering firearm storage, categories A through H), EN 1143-1 (the European burglary-resistance standard, grades 0 to VI), or a Sold Secure rating.
A safe with none of these on the compliance plate is a lockbox, not a rated security safe — treat it accordingly when comparing prices.
2. Read the category or grade letter, not just the price
Under AS/NZS 3809, firearm safes are graded by licence category: Category A and B cover most rifles and shotguns, Category C and D cover higher-capacity and self-loading firearms, and Category H covers handguns with extra locking requirements. A Secuguard GS3KL, for example, is tested and rated across Category A, B, C, D and H in one cabinet.
Under EN 1143-1, burglary safes run Grade 0 through Grade VI. Each grade up means significantly more resistance units earned against drilling, prying and explosive attack in lab testing — Grade I and II cover most home and small-business cash needs, Grade III and above are for high-turnover retail and commercial cash rooms.
3. Match the grade to your insurance limit, not the other way around
Insurers set cash and valuables cover based on the safe's grade, and the ratio differs by underwriter — call yours before you buy, not after a loss. A common mistake is buying a Grade 0 safe because it's cheap, then discovering the policy caps a jewellery claim at a fraction of what's inside.
If you're storing anything insured for a meaningful amount in 2026, get the insurer's minimum grade requirement in writing before choosing the safe.
4. Check the lock certification separately from the body rating
The body of the safe and the lock inside it carry separate certifications. A Grade II body with an uncertified lock can drag the whole unit's effective rating down in an insurance dispute. Look for a named lock brand (La Gard, S&G, or a digital lock with its own test certificate) referenced alongside the body grade on the spec sheet.
5. Confirm TDR rating for cash or drill-target storage
TDR stands for torch and drill resistant — a rating layer that matters for cash safes, jewellery safes and anything a determined thief would target with power tools rather than prying. Read the best high security safes with a TDR rating breakdown if you're storing cash takings or bullion rather than documents.
A burglary-rated body without TDR resistance still stops casual theft — it just won't hold up against someone who came prepared with a grinder.
6. Verify firearms storage compliance if the safe holds guns
Firearm storage isn't just about the safe's grade — it's a legal requirement tied to your licence category and state. Cross-check the safe against the AS/NZS safe standards guide before you buy, because compliance inspectors check the rating plate, not the marketing copy.
Common mistake: buying a Category A/B rated cabinet for a Category D or handgun collection. The lower category won't pass inspection and won't hold the extra ammunition storage most states require alongside the firearm.
7. Confirm the safe is anchored per its rating
Most EN 1143-1 and AS/NZS 3809 ratings assume the safe is bolted to a solid floor or wall. A Grade II safe sitting unanchored on carpet loses most of its practical resistance — a thief with a trolley just takes the whole unit. Anchoring is part of the rating being valid for insurance purposes, not an optional extra.
“A safe with no rating plate is a locked box, not a rated safe.”
Troubleshooting
- The listing says "burglar resistant" with no grade number — treat it as unrated until you find the compliance certificate; ask the seller directly for the AS/NZS or EN test reference.
- My insurer won't cover the full contents value — the safe's grade is likely below what the policy requires; check the cash/valuables ratio with the insurer before assuming the safe is the problem.
- The rating plate is inside the door and hard to read — photograph it and cross-reference the model number against the manufacturer's published spec sheet rather than guessing.
- Two safes claim the same grade at very different prices — check whether both are tested by an accredited lab; some sellers self-certify against the standard rather than submitting to independent testing.
- A gun safe passed AS/NZS 3809 testing but doesn't fit ammunition storage rules — categories A-H cover the firearm cabinet, but most states have a separate ammunition storage requirement that isn't part of the rating itself.
- A safe was rated years ago and the model has since changed — always match the exact model number and revision on the current listing, not an older generation with the same name.
Tools and resources
- Rating plate or spec sheet from the manufacturer (Chubbsafes, CMI, Guardall, Secuguard)
- Your insurance policy's cash/valuables schedule
- A Guardall KCR615 high security safe as a reference point for what a properly rated body and lock combination looks like on a spec sheet
- A tape measure and a look at your floor/wall construction, for anchoring compliance
What to do next
Once you can read a rating plate correctly, the harder question is picking the right size and grade for your specific storage needs.

FAQ
What is the difference between AS/NZS 3809 and EN 1143-1?
AS/NZS 3809 is the Australian standard covering firearm storage safes by licence category (A through H). EN 1143-1 is the European standard grading general burglary resistance from Grade 0 to Grade VI based on lab-tested resistance units.
How much cash cover does a Grade 0 safe get from insurers?
Cash and valuables limits vary by insurer and policy, so there's no fixed figure across the market. Always confirm the exact cover tied to a specific grade with your own insurer before buying.
Is a TDR rating better than a basic EN 1143-1 grade?
TDR (torch and drill resistant) is an added layer on top of the base burglary grade, aimed specifically at power-tool attacks. For cash and bullion storage in 2026, a TDR-rated body is worth the premium over a base-grade safe of the same size.
Does a safe need a rating to satisfy firearms storage law?
Yes. Most Australian states require an AS/NZS 3809 rated cabinet matching your licence category, and compliance inspectors check the rating plate directly rather than accepting a generic description.
Can I upgrade an unrated safe's rating after purchase?
No. Burglary and firearm ratings are tied to the tested body, door and lock as a single unit from the manufacturer. Adding aftermarket bolts or a new lock does not create a certified rating.
Why do two safes with the same grade have different prices?
Price differences usually come down to size, lock brand, fire protection add-ons, and whether the grade was independently lab-tested versus self-certified by the seller. Check for an accredited test certificate, not just the grade claim.
Does anchoring affect a safe's burglar rating?
Yes. Most AS/NZS 3809 and EN 1143-1 ratings assume the safe is bolted to a solid floor or wall. An unanchored safe loses much of its tested resistance in practice, regardless of the grade on the door.
One last thing
The single biggest gap buyers miss in 2026 isn't the grade number — it's assuming the rating on the box applies once the safe is sitting unanchored on a timber floor. Security Safes' rated units are tested as a bolted-down system; skip the anchoring step and you've effectively bought an unrated box at a rated price.
