Are Cheap Padlocks Any Good | The Honest Truth
A £20 padlock looks the part, but does it actually stop anyone? Susan Fenwick breaks down CEN grades, shackle types and when cheap is fine.
I had a job last month on a yard off Deneside. A bloke had three transit vans parked up, full of plumbing gear, all secured with those brass padlocks you can pick up two-for-a-tenner at the builder's merchant. Someone walked down the row and popped every one in about four minutes. Bolt croppers. Didn't even break a sweat.
He asked me afterwards, "Were they not decent padlocks?" They looked decent. That's different.
So let's deal with this properly, because there is a myth floating around that any padlock with a heavy-looking body is good enough. It isn't. And there's an opposite myth too, that you need to spend serious money on every padlock you own. Also not true.
Both things can't be right at the same time, so here's how it actually works.
The Myth: A Heavy Padlock Is a Secure Padlock
Walk into any hardware shop and you'll see padlocks that look solid. Chunky brass bodies, thick shackles, reassuring weight in your hand. People buy them because heavy equals strong, right?
Wrong. Mostly.
Brass is soft. A decent pair of bolt croppers cuts through a brass shackle the way you'd cut through a carrot. The body can be beautifully made and completely irrelevant if the shackle gives way in seconds. And on cheap locks, it usually does.
The body isn't even the only weak point. A lot of cheap padlocks can be shimmed open with a bit of cut-up can, or raked in under a minute with tools you can buy on Amazon. They look serious. They're not.
What the CEN Grade Actually Means
European padlocks are graded CEN 1 to 6. Six is the highest. Most locksmiths will tell you CEN 1 is basically decorative, and I'd agree with that.
Here's what the grades mean in plain terms:
- CEN 1 to 2: Resists minimal attack. Knocks off casual interference, that's about it.
- CEN 3 to 4: Resists a more determined attempt. Proper bolt croppers start to struggle at the upper end of this range, depending on shackle diameter.
- CEN 5 to 6: Resists sustained, tooled attack. You're looking at hardened steel, anti-drill plates, serious engineering.
Most of what you'll find for under £20, even from brands you've heard of, sits at CEN 1. Sometimes CEN 2 if you're lucky. The manufacturer isn't hiding this, it's usually on the packaging. People just don't look.
A CEN 3 or above from a brand like Squire, Abus, or a Closed Shackle rated lock from Abloy starts around £35 to £50. A CEN 5 or 6 worth buying, something like an Abloy Protec or a high-grade Mul-T-Lock, will be £80 upwards, sometimes well over £100.
That sounds like a lot. Whether it's too much depends entirely on what you're locking.
Open Shackle Versus Closed Shackle
This matters more than most people realise.
An open shackle padlock has a visible loop of steel sticking out above the body. Bolt croppers love that. Easy to get jaws around it, easy to cut. Even a hardened shackle can be vulnerable if enough of it is exposed.
A closed shackle, sometimes called a shrouded shackle, has the body built up around the shackle so there's almost nothing to get a tool onto. It's dramatically harder to crop. For anything outdoors and unattended, you want closed shackle. Full stop.
The plumber on Deneside had open shackle padlocks on all three vans. If he'd had closed shackle, hardened steel, even at CEN 3, the job would have taken much longer and probably not happened at all. Opportunist thieves move on when it gets slow.
Where a Cheap Padlock Is Actually Fine
I'm not going to pretend everything needs a £100 lock. That would be daft.
A £20 padlock is genuinely adequate in these situations:
- A garden gate that leads only to another gate or fence you'd just climb anyway
- A cupboard inside a building that's already properly secured
- A bin store or low-value enclosure where there's nothing worth stealing
- A temporary lock while you wait for a replacement
- Indoors, where the padlock is more of a deterrent to curious kids than professional thieves
If the consequences of someone getting through it are minimal, buy the cheap one. No shame in that.
Where It's False Economy
This is where people get it wrong, and it costs them.
Your shed with your tools in it. Your garage with your car or motorbike. A container with stock in it. A van loaded with equipment. A storage unit. An outbuilding on a property you're letting out in Murton or Peterlee. Anywhere with several hundred pounds worth of contents or more.
A decent closed-shackle padlock at CEN 4 or above, properly fitted to a hasp rated to match, costs maybe £50 to £70. The tools in that shed might be worth £2,000. That's not a hard calculation.
And the hasp matters too. I've seen people fit a good padlock to a flimsy hasp that pulls off the door frame with a screwdriver. The padlock's fine, the door fitting is the failure. If you're spending money on a serious padlock, spend a few quid more on a coach-bolted hasp, not a screwed-on one.
The Insurance Angle
If you're claiming for contents stolen from a shed or outbuilding, your insurer will sometimes ask what lock was on it. A CEN 1 padlock might not satisfy their requirements and you could find your claim reduced or refused. Some policies specify a minimum standard, often BS EN 12320 at Grade 3 or above for outbuildings.
Check your policy wording before you buy. It takes two minutes and it might be the difference between a paid claim and an argument.
What You Should Actually Buy
For a gate or low-risk use: whatever's cheap and fits. CEN 1 is fine.
For a shed, garage or van: closed shackle, hardened boron steel shackle, minimum CEN 3. Squire and Abus both make solid options in the £40 to £60 range that'll handle bolt croppers better than anything under £25 will.
For a storage container or serious commercial use: CEN 5 or 6, closed shackle, fitted to a proper close-shackle hasp. Budget £80 to £150 for the lock alone. Abloy and Mul-T-Lock are the names I'd reach for.
One last thing. Even a great padlock is only as good as the door, gate or frame it's fitted to. I've seen a £90 padlock on a shed with a rotten door frame. The door came off in one kick. Don't let the padlock be the most secure part of a weak system.
