An old safe looks as if it could stop anything. Against a modern house fire or a determined thief, it usually can’t, and your insurer probably won’t count it at all. Here’s what a safe from the 1880s to the 1950s still does well, what it doesn’t, and what keeping, restoring, replacing or selling it really costs.

Key takeaways
- Most safes made before the 1910s were never tested by an independent laboratory, and burglary testing only began in 1921. Even a mid-century safe with a test label was tested when its insulation was new.
- Insurers judge a safe by the certificate inside the door. An antique safe has none, so for cash and jewellery cover it usually counts as no safe at all.
- You don’t have to choose between the old safe and a new one. Many owners keep the old safe for display or everyday odds and ends, and put a small certified safe beside it for what matters.
- Old fire safes may contain asbestos in the filling or seals, so never cut, drill or blast one, or fix anything into it, before you know.

The short answer
If your old safe holds things you could replace, keep it and enjoy it. If it holds passports, deeds, cash or jewellery you’d be lost without, those belong in a modern safe with an independent fire or burglary rating, one your insurer has accepted in writing. The old safe can stay as furniture, be restored, or go to someone who wants it.
| Fire | Built to resist the fires of its day; untested if made before the 1910s, or tested only when new. Its filling may have dried out or taken in damp.12 |
| Burglary | About half an inch of protective metal in a wall about four inches thick, the rest fire filling. No tool-attack rating.34 |
| Insurance | Insurers look for the test label inside the door. An antique safe has none.5 |
| Asbestos | Possible in fillings and seals of fire safes made up to the late 1990s; check before any work.6 |
| Cheapest fix | Keep it, and put a certified safe beside it: UK from about £389 plus £229 installation.7 |

What an old safe does and doesn’t do in a fire
Most old safes in British and American homes were sold as fire safes. Their walls are a box within a box, packed with a filling that insulates or gives off steam: in Britain usually sawdust mixed with alum, whose water of crystallisation boils off in a fire and holds the inside near 212°F while it lasts.23 Our history of how the fireproof safe was invented covers the fillings maker by maker.
The weak point was known from the start. George Hayter Chubb warned in 1875 that the alum’s moisture is limited, and that sawdust absorbs damp, which can break the alum down long before any fire.2 So a Victorian safe that has spent a century in a cellar or an outhouse may have far less fire protection in its walls than the day it left the works, and there’s no way to tell from the outside.
Tested when new, if at all
Independent fire testing of safes is younger than most antique safes. Writing in 1923, Underwriters’ Laboratories’ own historian said manufacturers had begun submitting safes for its label only “a little more than a decade ago”. The labels it then issued were Class A (four hours in the test furnace), Class B (two hours), Class C (one hour) and “Insulated Cabinet” (45 minutes), each with the inside kept below 300°F. Safes in the A, B and C classes were also heated, hoisted thirty feet, dropped onto a heap of bricks and heated again.1 Mid-century American fire safes often carry these Class A, B or C labels.8
That label tells you how the safe performed when it was built. The same book makes the point itself: the insulation in a safe “may remain hidden away for a generation or more”, and the furnace tests show its heat resistance “when it is new”.1 A 1950s Class C safe is now about seventy years old.
Modern house fires are faster
Homes have changed around the old safe too. In repeated experiments by UL’s Fire Safety Research Institute, a room furnished with synthetic materials reached flashover, the point where everything in the room ignites, in 4 minutes 50 seconds; an identical room furnished with natural materials took more than 30 minutes.9 A safe built for the slower fires of horsehair sofas and wool rugs now faces a hotter start.
Today’s fire ratings are the descendants of those 1923 tests. In UL 72 the furnace reaches about 1,000°F (538°C) within five minutes and follows a set temperature curve for the rated time; Class 350 means the inside stays below 350°F, the limit for paper, and the optional impact test still drops the safe from 30 feet.10 In Europe, EN 1047-1 classes data cabinets by minutes and by what they protect, with a fire shock and impact test.11 Our guide to safe fire ratings explains the classes and what each one protects.
“A fire-safe container must have its safety proved by fire.”
Harry Chase Brearley, A Symbol of Safety, 1923
What it does and doesn’t do against a burglar
Weight is the old safe’s best feature. A thief can’t carry off a few hundredweight of iron on his own, and modern standards still treat weight as part of security: a UL TL-15 safe must weigh at least 750 lb (340 kg) or come with anchoring instructions.12 A heavy old safe in an awkward corner is a nuisance to steal, and against a casual opportunist that counts for something.
The thickness, though, is mostly filling. On a typical British fire safe, the walls and door measure about four inches, but only about half an inch of that is protective metal; Milner’s early bodies were sheet wrought iron of 1/8 to 3/16 inch riveted to an angle-iron frame.3 Those safes were made to keep papers from burning, not to resist tools. Bank safes and the round “cannonball” safes were a different class of object, built against burglars.
No safe of the period had a tool-attack rating either. When UL began burglary testing in 1921, it noted that there had been no “standards” of design and construction for safes, vaults or locks, and that a safe’s value lies in the time it takes to defeat.4 That idea, protection measured in minutes against set tools, is still the basis of UL’s TL ratings and the European EN 1143-1 grades. Our guide to burglary ratings from RSC to TL-30 explains them. We don’t publish anything on how old safes are attacked; the history of safe-cracking tells the story without the method.
Then there are the keys. An old key or combination may be known to people you’ll never trace: previous owners, their families, a locksmith who opened it decades ago. If you go on using an old safe, have a safe engineer change the combination or fit a new lock. The Master Locksmiths Association in the UK, SAVTA in the US and the MLAA in Australia and New Zealand can find one.13
Insurance: an old safe counts as no safe
This is where most owners get a surprise. In the UK and Europe, insurers judge a safe by the test label inside the door, which names the standard (EN 14450 or EN 1143-1), the grade and the body that certified it.5 Each grade carries a customary cash rating, from £2,000 for EN 14450 S1 to £10,000 for EN 1143-1 grade I, with valuables usually allowed at ten times the cash figure.14 Our guide to Eurograde and cash ratings goes through the full table.
An antique safe has no label, so it has no grade. Many UK home policies only cover jewellery left at home if it is locked in a safe whose cash rating, multiplied by ten, covers its value, and some require the safe to be installed to the maker’s instructions.15 Another policy wording, quoted in a Financial Ombudsman decision, requires the safe to be “permanently attached or secured to the home”.16 A loose Victorian safe meets neither condition.
There’s a grey area for later 20th-century safes. A UK safe engineer offers to look up the weight and overnight cash rate of discontinued Chubb, Chatwood and Milner ranges, sometimes for a fee, and points out that insurers will want to know a safe’s maker and age.17 So if you have a post-war British safe, it’s worth asking. Whatever you have, ring your insurer before you rely on it, give them the maker and any model or serial number, and get the answer in writing; even professional jewellers are told to ask which safes their carrier will accept.18
Check for asbestos first
Ireland’s Health and Safety Authority notes that some makers used asbestos in door seals and wall fillings into the late 1990s. It’s no risk in normal use, but safes presumed to contain it must not be cut or drilled, and a safe with exposed filling should be taken out of use until tested.6 That matters for every option below: restoring, moving, scrapping or bolting anything into the old safe. Read whether old safes contain asbestos before any work starts.
Your five options
None of these is the “right” answer for every safe. A plain, damaged 1930s office safe and a painted Victorian safe with your great-grandfather’s name in gold leaf are different decisions, which is why it pays to know what you have first.
1. Keep it as furniture or display
The cheapest option, and often the best one. An old safe makes a fine cabinet for things a burglar doesn’t want and a fire wouldn’t ruin your life over: family photographs you’ve also scanned, old letters, the good whisky. It costs nothing unless the lock needs a service; a US cost guide puts that at $150–450 a lock.19
Keep it somewhere dry. Iron usually needs relative humidity above about 65% to rust indoors, so a heated room is kinder to it than a garage.20 Damp is also what spoils the old filling.
2. Restore it
Restoration makes an old safe work smoothly and look right. It doesn’t give it a certificate, a fresh fire rating or a place on your insurance schedule, so restore a safe because you love it, not to make it secure. In the US, a 2026 cost guide puts a medium safe at $900–3,500, and one of the best-known restorers quotes lead times “often 36 months or more”.1921 In the UK, restorers quote on enquiry; one dealer-restorer offers fully restored Victorian safes at £2,995 and £6,295.22
Before anyone strips it, read our guide to restoring an antique safe: original paint, lettering and transfers are where most of the value sits, and they can’t be put back.
3. Put a modern safe inside it or beside it
This is the compromise many owners land on, and it works well if you get the details right.
- Inside: small fire boxes and document chests. A modern fire chest sits happily on an old safe’s shelf and keeps its own rating, because the rating belongs to the box. UK prices start at £37.49 for a 5-litre, 30-minute chest.23 Don’t count on the old safe adding anything to it.
- Beside: anything your insurer needs to approve. A certified burglary safe only earns its rating when it’s anchored as its maker specifies. European guidance is that free-standing safes under 1,000 kg should be anchored by specialists, without drilling extra holes in the safe, and insurers write similar conditions into policies.2416 Bolting a new safe through the floor of an old fire safe means drilling into filling that may contain asbestos.6 Put the rated safe next to the old one, or in a cupboard, and fix it to the floor or wall.
For scale: a 25 kg Chubbsafes HomeVault S2, rated EN 14450 S2 with a £4,000 cash rating, was £389 at a UK retailer in October 2026, plus £229 for installation.7 It’s not fire resistant, which is another reason the two safes can share the work.
4. Sell it or rehome it
Prices vary more than people expect. At one end, a large Milners’ patent safe made a £10 hammer price at a Surrey auction in 2021; at the other, a Wisconsin dealer sold a 315 lb Hall’s safe in original paint for $1,650.2526 Later British cash safes have a trade value too: a Coventry dealer offers a reconditioned Chatwood Milner Minor at £375 plus VAT.27 Our guide to whether old safes are worth anything has many more sale prices.
Moving is often the biggest cost. The Master Locksmiths Association estimates UK removal and disposal from about £110 plus VAT for a safe up to 500 kg, and says the cost of removing an old safe is often more than it’s worth; one specialist firm starts at £250.2829 In the US, a 2024 locksmiths’ price survey put typical safe moves at $250–500.30 As scrap, a 250 kg safe brought only about £15 to £35 at autumn 2026 UK prices, by our arithmetic.31 See how to move or get rid of an old safe for removers, museums and scrap yards.
5. Buy new: choosing a modern safe in brief
- Start with what you’re protecting. Papers and passports need a fire rating; cash and jewellery need a burglary grade; backup drives need a data rating, because they fail at lower temperatures than paper.32 If you need two of these, look for two certificates.
- Look for an independent certifier. A label from a test house is not the same as a maker’s own claim. One US dealer tells buyers to weigh UL or ETL test reports against unverified factory claims.33 The fire and cash rating guides linked above list the bodies to look for.
- Ask your insurer before you buy. Give them the model and grade and get the cover in writing.18
- Budget for fitting. Delivery, stairs and anchoring are part of the price, and most rated safes only count once they are anchored.24
- Know who made it. Many familiar old names now belong to large groups, and some new brands are made by someone else entirely. Our guide to who makes safes today traces the brands to their owners.
What each option costs
Published prices, with the date we checked them. Retail prices change often and none of these is a quote; restoration and moving in particular depend on the safe, the stairs and the distance.

| Buy new: burglary safe | EN 14450 S2 from £389 + £229 fitting; Eurograde 0 from £385.56, grade I from £592.94, top grades over £21,000 (Oct 2026)36 | UL TL-15: $1,688–10,785 at one dealer (Oct 2026)33 |
Decision table: which option fits your safe?
| Your situation | Best fit | Why |
|---|---|---|
| It holds nothing you couldn’t replace | Keep it as furniture | Costs nothing; the safe does what you need |
| You keep papers or passports in it | Add a modern fire-rated box or safe | Old filling is untested or tested only when new |
| Your insurer wants a rated safe for jewellery or cash | Certified safe beside it, anchored | Only a graded, accepted, fixed safe counts |
| Original paint, lettering or a family name on it | Conserve or restore, and keep it | The finish is the value; new paint can’t replace it |
| It’s plain, damaged or in the way | Sell, give away or scrap | Moving often costs more than it’s worth, so sort the destination first |
| Filling is crumbling or leaking dust | Stop and get it tested | Possible asbestos; no cutting, drilling or moving until you know |
| You don’t know the maker or age | Identify it first | Maker and date change the value and the right choice |

How we got here: from public burnings to test labels
For most of the 19th century, a safe’s reputation rested on salesmanship. Makers staged public burnings and contests, and Chubb told his readers in 1875 to put little faith in public tests unless they were run by disinterested people.2 Independent laboratories took over the job in the 20th century, and that’s the line every modern rating descends from.
- 1801 Richard Scott patents a method of fireproofing, the first on Chubb’s list of English safe patents.2
- 1867 The “Battle of the Safes” at the Paris Exhibition pits Chatwood against the American maker Silas Herring.37 More in our history of Chatwood safes.
- 1875 Chubb warns that sawdust and alum fillings can run out of moisture or absorb damp.2
- 1910s American safe makers begin submitting safes to Underwriters’ Laboratories for its label.1
- 1921 UL formally begins burglary protection testing in September.4
- 1923 UL’s fire labels run from Class A (four hours) to Insulated Cabinet (45 minutes), with a 30-foot drop test.1
- Today UL 72 fire classes, UL TL ratings, and European EN 1047-1, EN 14450 and EN 1143-1 certificates.105
How we put pages like this together, and what we don’t do (we don’t test safes ourselves), is set out in how we research modern safes.
Myths and facts
It has lasted a hundred years, so it will survive a fire.
Its filling was tested, if ever, when new. Fillings dry out or take in damp, and modern rooms burn faster.
Four-inch walls make it stronger than a modern safe.
Only about half an inch of an old fire safe’s wall is protective metal. The rest is filling.
A restored safe is as good as a new one.
Restoration renews the paint and the lock work. It doesn’t add a fire rating, a burglary grade or insurance approval.
“Fireproof” on a new safe’s box means it has been tested.
Look for the standard and the test house that certified it. A maker’s own claim is not a rating.
Frequently asked questions
Are old safes better than new ones?
Better made, often, and far better looking. More secure, no: an antique safe has no tested fire or burglary rating and an insurer won’t count it. For valuables, a certified modern safe wins.
Is an antique safe still fireproof?
Possibly, a little, but nobody can tell you how much. Fillings dry out or absorb damp, and even safes with an old test label were tested when new. Keep important papers in a modern fire-rated safe.
Will my insurer accept an old safe?
Rarely for an antique, because insurers rate safes from the test label inside the door. Some later 20th-century British safes have a historic cash rate on record, so ask your insurer and get the answer in writing.
Can I put a modern safe inside my old one?
A fire chest or document box, yes. A rated burglary safe should go beside it instead, anchored to the floor or wall as its maker specifies, without drilling the old safe.
Should I get rid of my old safe?
Only if you don’t want it or can’t house it. Find out what it is first: moving costs often exceed the value of a plain safe, while a decorated or rare one can be worth keeping or selling to a collector.
