Are Cheap Padlocks Any Good | A Locksmith's Verdict

I had a job last month in Wavertree, a bloke who'd had his shed broken into twice in six months. First time, they snapped the hasp off. Second time, they cut straight through the padlock he'd replaced it with. It was a £18 job from a well-known DIY chain, looked the part, shiny silver body, chunky enough to feel reassuring in the hand. Took a pair of bolt croppers about four seconds.

He asked me what he'd done wrong. The answer wasn't complicated. He'd bought a padlock based on how it looked, not on what it was rated to survive.

This happens constantly. And the internet doesn't help, because most buying guides either recommend spending a fortune on everything or give you a vague 'buy a good quality lock' and leave you none the wiser. So let's actually sort this out.

The Myth: A Padlock Is a Padlock

The thing people repeat is roughly this: any padlock is better than no padlock, and the cheap ones are probably fine for most things. The logic feels reasonable. A padlock is a lump of hardened metal. It's got a shackle, a body, a locking mechanism. How different can they really be?

Very different. Almost incomparably different, as it turns out.

What CEN Grades Actually Mean

Padlocks sold in the UK and Europe are tested against a standard called CEN (European Committee for Standardisation), graded from 1 to 6. Grade 1 is the bottom. Grade 6 is the sort of thing securing a bank vault. Most decent hardware shops don't actually label these grades on the packaging, which is part of the problem.

Here's what the grades roughly translate to in the real world:

• CEN 1 to 2: Resists hand tools for a short period. Someone determined with a screwdriver or basic croppers gets through quickly.
• CEN 3: Resists bolt croppers up to a point. Better body construction. This is where you start getting something worth calling a security padlock.
• CEN 4: Angle grinder resistance begins to matter here. Hardened steel shackle, serious anti-pick core.
• CEN 5 to 6: Commercial and high-security use. Brands like Mul-T-Lock and Abloy sit here. You're spending £80 to £200 minimum.

Your average £20 padlock from a supermarket? CEN 1 if you're lucky. Often not rated at all, because the manufacturer knows it won't pass.

Open Shackle vs Closed Shackle

The other thing that trips people up is shackle design. Open shackle padlocks, the classic horseshoe shape with exposed metal on both sides, give croppers a clean bite. Even a CEN 3 padlock with an open shackle can be beaten faster than the grade suggests, because the shackle itself is the weak point.

Closed shackle or shrouded shackle padlocks protect most of the shackle inside the body. There's very little exposed metal to get a tool onto. For a shed, garage, or storage unit, this matters enormously. An open shackle CEN 3 and a closed shackle CEN 3 are not the same thing in practice, even if they share a rating.

I fit a lot of closed-shackle Squire SS65CS and Abus 83/55 padlocks on Merseyside jobs. They're not glamorous. They work.

Where a Cheap Padlock Is Actually Fine

Here's where I'll take a slightly contrarian line: a cheap padlock is not always a waste of money. Context is everything.

If you're securing a garden gate that's purely there to stop the dog getting out, not to deter a burglar, a £12 padlock does the job. If you're locking a wheelie bin enclosure in an L1 city centre courtyard, same answer. Nobody is going to crop a bin lid.

A padlock on a low-value, low-risk item with no tools or valuables behind it? Fine. Cheap. Appropriate.

The mistake isn't buying cheap padlocks. The mistake is buying cheap padlocks for the wrong jobs.

Where It's a False Economy

The shed. Every time. Especially in areas like Huyton, Kirkby, or Speke where garden tool theft is a regular problem I see on callouts. Tradespeople keeping gear overnight in a van or storage unit. Garages in terraces across Anfield, Walton, or Kensington where the back entry gives easy cover.

A decent set of tools can be worth £500, £1,000, £2,000 or more. The padlock keeping them safe costs, what, another £40 to £60 for a proper CEN 4 closed-shackle model? The maths isn't hard.

The other thing people don't think about is the hasp. A brilliant padlock on a cheap hasp screwed into soft wood with 25mm screws is still a joke. I've seen padlocks so good that a burglar gave up on them, ripped the hasp off the frame instead, and walked straight in. The padlock was still locked when the homeowner found it on the floor.

Fit a heavy-duty steel hasp, use coach bolts that go through the door or frame, and then put the decent padlock on it. Half measures don't work.

What to Actually Buy

For low-risk stuff: anything with a solid body that fits the job. Don't overthink it.

For a shed with tools, a garage, or a storage unit:

• Minimum CEN 3, closed shackle
• Look at Squire, Abus, Mul-T-Lock, or Abloy
• Budget £40 to £80 for the padlock itself
• Match it with a proper steel hasp and coach bolts
• If the shed door is flimsy, that's the thing to fix first

For a site compound or commercial storage in an L postcode, you're looking at CEN 4 minimum, probably Mul-T-Lock or Abloy Protec2, and you'll spend £100 or more. Worth every penny compared to a theft claim and lost tools.

The Rating Nobody Checks

Sold Secure is worth mentioning too. It's a third-party testing body that rates padlocks Bronze, Silver, and Gold. Gold roughly lines up with CEN 4. If a padlock has a Sold Secure Gold rating on the packaging, that's a meaningful signal someone has actually tested it properly, not just that the manufacturer has graded their own product.

Most £20 padlocks have no Sold Secure rating. Because they wouldn't get one.

The bloke in Wavertree, by the way, now has a closed-shackle Squire SS65CS on a proper hasp with coach bolts. Nobody's been back since. Funny how that works.
