This is one of the most common questions we get, and it catches a lot of people out: a "fireproof" safe and a "security" safe are not automatically the same thing, and buying the wrong one for what you're actually storing can leave you unprotected.
They're tested for completely different threats
A security safe is tested against physical attack — drilling, prying, cutting, and forced entry — for a defined period of time. The rating (EN14450 or EN1143-1, covered in our ratings guide) tells you how much resistance it offers to a thief.
A fire safe is tested against heat. It's placed in a furnace at a controlled temperature for a set time (commonly 30, 60, 90 or 120 minutes) and then checked to see whether the internal temperature and humidity stayed low enough to protect paper documents — or, on media-rated models, digital storage like hard drives and USB sticks, which are damaged by much lower temperatures than paper.
Why one doesn't automatically give you the other
A safe built purely for fire protection often uses lighter-gauge steel and simpler locking, because its job is insulation, not resisting an angle grinder. A safe built purely for security uses thick steel and hardened locking, but that construction doesn't necessarily include the insulating fire-board layer needed to survive a house fire.
Some ranges are tested and rated for both — our product pages list both fire rating and security rating separately where they apply, so you can check exactly what a given model actually protects against rather than assuming.
How to decide what you actually need
- Cash and jewellery, no irreplaceable documents — a security-rated safe is likely sufficient on its own.
- Passports, property deeds, family photos, legal documents — you need genuine fire protection, since these usually can't be reissued for free or replaced at all.
- Backup drives, laptops, or digital media — check specifically for a digital media fire rating, not just a paper rating. Digital media is damaged by far lower temperatures than paper, so a safe rated for paper alone won't protect it.
- Business cash takings plus important paperwork — look at a combined security and fire rated safe, or keep documents in a dedicated fire file alongside a separate security safe for cash.
The practical answer
If what you're storing includes anything genuinely irreplaceable — documents, digital backups, family keepsakes — fire protection isn't optional, whatever the security rating says. If it's purely cash or valuables with no fire risk to worry about, a security-only safe rated to your insurer's requirement is the more cost-effective choice.
