Are Cheap Padlocks Any Good | When to Spend and When to Save
CEN grades explained, closed vs open shackle, and where a £20 padlock is fine versus where it'll cost you far more than you saved.
A £20 padlock from a hardware shop in Doncaster or a supermarket on the A1 near Blyth. You've seen them. Brass body, shiny shackle, reassuring weight in the hand. The packaging says "heavy duty" or "high security" in bold type. It doesn't say who tested it, what they tested, or whether it passed anything at all.
That's the problem. Not the price. The silence on the label.
The Myth: Price Equals Protection
The common belief is that a more expensive padlock must be better, and a cheap one must be rubbish. People repeat this, and it's half right at best. I've seen a £15 padlock doing a perfectly reasonable job on a garden gate in Austerfield, and I've seen a £45 padlock on a Finningley smallholder's tool store that a determined teenager could open in under a minute with a pair of bolt croppers. Price tells you almost nothing on its own. Certification tells you everything.
What CEN Grades Actually Test
The European Committee for Standardisation grades padlocks from 1 to 6 under EN 12320. Each grade corresponds to a specific level of attack resistance, tested in a lab under controlled conditions. The grades are not marketing. They're a defined sequence of tools and time.
| CEN Grade | Resistance Level | Typical Attack Resisted |
|---|---|---|
| 1 | Basic | Casual hand force |
| 2 | Low | Light tool attack |
| 3 | Medium | Moderate tool attack (bolt croppers up to 300mm) |
| 4 | High | Heavy tool attack, longer duration |
| 5 | Very High | Power tools, sustained attack |
| 6 | Maximum | Professional attack, specialist tools |
Most padlocks on the shelf of a high street DIY shop are Grade 1 or Grade 2. The packaging won't always say so. A Grade 1 padlock resists someone pulling on the shackle with their hands. That's the test. That's it. A screwdriver, a hammer, a set of bolt croppers from any builder's merchant, and it's done.
For a domestic shed in Harworth or a garage in Rossington, you want Grade 3 at an absolute minimum. Grade 4 is better. Brands like Abloy, Squire, Abus, and Mul-T-Lock make padlocks that sit at Grade 4 and above. You're looking at £40 to £100 depending on spec. Still not frightening money for what they're protecting.
Sold Secure Is the Other Number to Know
Sold Secure is a UK testing scheme run on behalf of insurers and police. It grades padlocks Bronze, Silver, Gold, and Diamond. Those categories map roughly to real-world attack scenarios, tested by people who know how criminals actually work, not just by static load tests.
A Sold Secure Gold padlock has resisted attack for at least five minutes with common tools. Diamond means at least ten minutes with more aggressive tools. Neither grade is impenetrable. What they do is separate the padlocks that fail in seconds from the ones that require genuine effort, noise, and time. Noise and time are your two best friends in security.
If you're padlocking a shed on a residential street in Bawtry or Tickhill, Sold Secure Gold is the sensible floor. Diamond if the shed holds tools you use for work.
Open Shackle vs Closed Shackle
This matters more than most people realise. An open shackle padlock exposes a long loop of metal above the body. That loop is what bolt croppers bite. A closed shackle (sometimes called a shrouded or protected shackle) wraps the body around most of the shackle, leaving almost no purchase for the jaws of a cropper.
You can buy a cheap open shackle padlock and a more expensive closed shackle padlock at the same nominal CEN grade. The closed shackle one is harder to attack. Full stop. If the hasp on your gate or door lets you use a closed shackle model, use one.
Where a Cheap Padlock Is Genuinely Fine
I'll be straight about this. Not everything needs a Sold Secure Diamond padlock.
- A garden gate you leave unlocked half the time anyway, and which leads to a garden with no tools, no bikes, nothing of value
- A fence panel hooked back in winter to improve drainage access
- A holiday marker, where you're just making it obvious the property isn't being accessed during works
- A temporary securing job on a skip or similar, where the padlock will be cut off by the hire company anyway
In those cases, a Grade 1 or Grade 2 padlock does the actual job required, which is keeping something closed, not keeping someone out.
Where a Cheap Padlock Is False Economy
This is where it gets expensive. I've been called to properties in Martin Common and out towards Misson where the story is the same: tools gone, shed door still locked. The padlock hasp was sheared off. The padlock itself was irrelevant.
But more often I arrive and the padlock has simply been cut, twisted off, or in one memorable case in Retford, picked in a car park. A Grade 1 padlock offers almost no resistance to a motivated thief with bolt croppers they bought legally from a tool shop.
Where cheap padlocks are false economy:
- Any outbuilding with tools, machinery, or bikes worth more than roughly £200
- A garage containing a vehicle, even a motorbike
- Gates that give access to a rear garden where your back door or patio doors are the real target
- Storage on commercial premises, workshop stores, anything a tradesperson uses to run their livelihood
A tradesperson in Harworth who keeps £3,000 of kit in a van-converted store shed and uses a £18 padlock from a supermarket is not being thrifty. They're betting their income on a piece of brass that will fail in about four seconds.
What to Actually Buy
For domestic sheds and garages in the DN10 postcode area, I'd point people towards the Squire SS50CS (closed shackle, Sold Secure Gold) at around £45 to £55, or the Abus 83CS series in similar territory. For higher value premises, the Abloy Protec2 range starts around £90 and is genuinely resistant to picking and drilling, not just physical attack.
Mul-T-Lock make padlocks that carry both CEN Grade 4 and Sold Secure Gold, and they're available through locksmith trade suppliers rather than DIY sheds, which means you also get advice on the right hasp and fitting, because a Grade 6 padlock on a rotten hasp screwed into soft timber is still useless.
The padlock and the hasp are a system. Both have to work.
One Last Thing About That Shackle
If you're shopping online and the listing doesn't mention a CEN grade or Sold Secure rating, treat it as Grade 1 until proven otherwise. "Heavy duty" is not a standard. "High security" is not a standard. "Military grade" is especially not a standard, and frankly that phrase should be enough to close the browser tab.
Spend where it matters. On the gate to your empty patio, save away. On the shed with your livelihood in it, a £60 padlock is not expensive. It's just honest arithmetic.
If you're not sure what you've currently got or whether your hasp fitting is doing the padlock any favours, Rapid Response covers Bawtry and across the DN postcodes. Average arrival under 30 minutes where possible, and we'll give you a price before we start. No obligation to use us for the upgrade if you'd rather source the hardware yourself.
