Are Cheap Padlocks Any Good | The Honest Answer

I had a job in Galley Hill a few weeks back where a bloke had lost the keys to his storage unit. Standard enough. What wasn't standard was the padlock: a £4.99 brass thing from a discount bin, the kind with a shackle you could lever off with a decent tug. He hadn't lost the keys. His neighbour's teenager had just pulled it open with both hands.

So yes, some cheap padlocks are genuinely useless. But 'cheap padlock bad, expensive padlock good' is too simple, and if that's all you take from this, you'll end up wasting money in the wrong places.

The Myth: A Padlock Is a Padlock

People say it all the time. 'I just need something to keep it shut.' And for some jobs, that's entirely true. For others, it's the sort of logic that ends with your tools gone and an insurance claim that doesn't pay out because your shed lock wasn't up to the policy wording.

The myth is that all padlocks do roughly the same job and a higher price is mostly branding. It isn't. There is a measurable, tested difference between grades, and it matters enormously once a determined thief turns up with a crowbar or a set of bolt croppers.

What the CEN Grade Actually Tells You

CEN grades run from 1 to 6. Very few residential padlocks hit above a 4, and most of the cheap ones floating around DIY sheds and market stalls are Grade 1, or ungraded entirely.

Here's what the grades mean in plain terms:

• Grade 1: Resist casual interference only. A sharp kick or a decent pull can open many of these.
• Grade 2: Resists basic tools, a screwdriver, a hammer. Still not much against bolt croppers.
• Grade 3: Starting to get serious. Better shackle steel, more attack resistance.
• Grade 4: Good for commercial premises and proper outbuildings. Tested against angle grinders for a defined period.
• Grade 5 and 6: High-security applications. Think industrial sites, cash-in-transit points.

For a domestic shed or garage in New Bradwell or Old Stratford, a CEN Grade 3 or 4 with a closed shackle is the right target. Products like the Abus 83CS, the Squire SS65CS, or anything carrying the Sold Secure Gold standard will sit in that bracket.

A £20 padlock? Almost certainly Grade 1, ungraded, or rated Grade 2 at best.

Open Shackle Versus Closed Shackle

This matters more than most people realise.

An open shackle padlock leaves the U-shaped bar exposed on both sides. Bolt croppers can get in and snap it. Even a decent Grade 3 open-shackle padlock is easier to defeat than a lower-graded closed-shackle one, because the shackle is the weak point and you've left it wide open.

A closed-shackle padlock recesses the shackle into the body. Almost nothing gets a cropper on it cleanly. That single design change transforms the security picture.

Most of the cheap padlocks you'll find for under £20 are open shackle. That's fine for some uses. For anything worth protecting, it isn't.

Where a Cheap Padlock Is Absolutely Fine

I'm not going to pretend every padlock needs to be a Mul-T-Lock or a Squire. That's not honest.

A £15 padlock is perfectly adequate for:

• A garden gate that doesn't lead anywhere valuable. You want it shut, not impenetrable.
• Keeping a bag closed during travel, where deterrence is the whole point.
• A bin store or recycling cage. Nobody's breaking in for your blue bin.
• A low-value allotment plot where the main aim is keeping the gate from swinging open.

In those situations, spending £60 on a closed-shackle Grade 4 is genuinely unnecessary. Put the money elsewhere.

Where a Cheap Padlock Is False Economy

This is where people get it badly wrong.

The shed with your tools in it. A set of decent hand tools runs to hundreds of pounds. Power tools, easily more. I've been to jobs in Calverton and Hanslope where a tradesperson has had a van's worth of gear taken from an outbuilding secured with an open-shackle padlock that cost less than a pint. The insurance excess alone hurt more than the lock upgrade would have.

A side gate giving access to your back garden. If someone gets through that gate unseen, they can work on your back door at leisure. A £20 padlock on a hasp isn't a gate lock. It's a suggestion.

Any hasp and staple fitted to a wooden door. The lock is only as good as its fixing. If the screws are short or the hasp is mild steel, a decent padlock is irrelevant anyway, they'll just lever the hasp off the frame. But a bad padlock on a bad hasp is two layers of nothing.

Garages in MK11 postcodes and beyond where your contents aren't covered below a certain standard. Check your policy wording. Some insurers specify a minimum CEN grade or a Sold Secure-rated padlock for outbuilding contents cover. Fit a cheap one, make a claim, get knocked back. I've seen it happen.

The Sold Secure Standard: Use It

Sold Secure is a testing house backed by the insurance industry and the police. Their Gold rating for padlocks broadly aligns with CEN Grade 4 attack resistance. Silver is Grade 3. Bronze is Grade 2.

If a padlock carries a Sold Secure Gold mark, you can trust the rating. If it doesn't carry any mark at all, you're buying on faith.

Brands worth looking at: Abus, Squire, Master Lock (their commercial range, not the budget one), and Abloy for high-security applications. Expect to pay £35 to £80 for something genuinely rated. That's not a lot against what it's protecting.

One More Thing: The Hasp

I'll keep saying this until people listen. The best padlock in the world is useless on a flimsy hasp with 25mm screws into soft timber. If you're upgrading your shed security, replace the hasp at the same time. A closed-shackle padlock on a heavy-duty close-shackle hasp, with coach bolts going through the door rather than screws, is a serious obstacle. Either element alone is not.
