Are Cheap Padlocks Any Good | When £20 Is Fine and When It Isn't
CEN grades, closed-shackle facts and real examples. Find out where a budget padlock is fine and where it's false economy in Ealing and West London.
Walk into any hardware shop in Ealing Broadway or scroll through Amazon for thirty seconds and you'll find padlocks for £8, £15, £22. Shiny. Hefty-looking. Sometimes sold in twin packs, which feels like a bargain. The question people type into Google, usually after something has been stolen, is whether those padlocks were ever actually any good.
Short version: sometimes yes, sometimes catastrophically no. The difference is not price alone. It's what the padlock is protecting, and whether anyone bothered to test it.
The Myth: A Heavy Padlock Is a Secure Padlock
Weight is the number one way cheap padlocks fool people. A die-cast zinc body feels substantial in the hand. It isn't. Zinc is soft enough that a decent pair of bolt croppers goes through it the way a knife goes through warm brie. The shackle, the U-shaped bar, is often the real weak point. A thin steel shackle with a 6 mm diameter can be cut in under ten seconds. I've timed it.
The lock on a garden gate in Northfields that looks like a serious piece of kit is often exactly the kind that fails this test. Burglars don't need to pick it. They don't even need to try.
What CEN Grades Actually Mean
The European Committee for Standardisation grades padlocks from 1 to 6. Most people have never heard of this scale. It's the one that matters.
| CEN Grade | Resistance Level | Typical Use |
|---|---|---|
| 1 | Minimal, a deterrent only | Luggage, lockers |
| 2 | Low risk environments | Internal gates, low-value storage |
| 3 | Medium risk | Garden sheds, outbuildings, general outdoor use |
| 4 | High risk | Commercial storage, garages with tools or equipment |
| 5–6 | Very high risk | High-value commercial premises |
A grade 3 padlock has to withstand 5 minutes of attack with bolt croppers, saws, drills and picking tools under test conditions. Grade 4 doubles that. The testing is done on a fixed, secured body, which is already more lenient than real life where a determined person can apply leverage at angles the test doesn't cover.
Most cheap padlocks are grade 1 or unrated entirely. An unrated padlock tells you the manufacturer didn't submit it for testing. Draw your own conclusions.
Brands worth looking at for rated locks: Abus, Master Lock (specifically their Pro and Granit ranges), Squire, and Mul-T-Lock. Sold Secure also runs its own Bronze, Silver and Gold ratings, which mirror CEN grades reasonably well and are easier to find stamped on retail packaging.
Open-Shackle vs Closed-Shackle: This Gap Matters More Than Grade
An open-shackle padlock exposes the shackle on both sides. A closed-shackle design, sometimes called a closed-body or shrouded padlock, wraps the body around the shackle so only a few millimetres are exposed. That small change makes bolt-cropping almost impossible because there's no room to get the jaws in.
For a shed in Hanwell or a storage unit near the Park Royal industrial estate, a closed-shackle padlock at grade 3 or above is the minimum I'd suggest. The Abus 83/55 is a common recommendation. It'll cost you £35 to £45 depending on where you buy it. It is not glamorous. It works.
An open-shackle padlock, even a grade 3, is a weaker choice for anything valuable. The shackle is the target.
Where a £20 Padlock Is Perfectly Fine
Not everything needs a £60 Squire SS50CS. Honest assessment:
- A gate into a garden you can see from the house, where the padlock is a secondary measure and not the only thing between a thief and anything valuable.
- A pool fence or a play area gate, where the purpose is keeping children safe rather than deterring a burglar.
- A communal bin enclosure in a block of flats in South Ealing or Ealing Common, where nothing of value is inside.
- Luggage on a short train journey.
In these situations a grade 1 or 2 padlock does what you need. It keeps an honest person honest. It stops the gate swinging open. It's not pretending to be something it isn't.
Where It's False Economy
This is where I see the real cost. A tradesperson in Greenford who stores £4,000 of power tools in a van-top box, locked with a £14 padlock from a petrol station. A self-storage unit near Southall locked with a twin-pack deal from a supermarket. A garden shed in Pitshanger containing a ride-on mower and two road bikes.
The logic goes: "It's just a shed." But the contents aren't just anything. Replace a Dewalt kit or a quality bike and you're looking at £800 to £2,500. A Squire SS50CS closed-shackle padlock costs about £55 retail. The maths is not complicated.
Landlords are another group who underestimate this. A communal entrance gate in W5 with a cheap padlock is an invitation. If a tenant's bike or furniture gets taken from a communal area, the reputational and sometimes legal implications for the landlord are disproportionate to the cost of a decent lock.
The Hasp Problem Nobody Mentions
Here's something that trips people up regularly. You can buy the best padlock in the world and fit it to a hasp that's held on with four 25 mm screws into softwood. The hasp is ripped off the door in seconds. The padlock is irrelevant.
A proper hasp for a shed or outbuilding should be a closed-shackle hasp, which shields the screw heads when locked so they can't be removed. Fixings should be coach bolts, going through the door with a nut and washer on the inside, not wood screws. This detail costs almost nothing extra and is the difference between a locked door and a theatre prop.
What to Actually Buy
If you want a simple steer:
- Casual, low-value use: Any decent branded grade 1 or 2. Abus 55/40 around £12, fine.
- Garden shed, outbuilding, bike storage: Closed-shackle, grade 3 minimum. Sold Secure Silver at least. Abus 83/55, Squire SS50CS, or Master Lock M736. Budget £35 to £60.
- Commercial storage, van security, high-value equipment: Grade 4, Sold Secure Gold. Squire SS65CS or Abus Granit 37/55. Expect to pay £65 to £100.
None of these will stop a truly determined and well-equipped attacker with unlimited time. No padlock will. What they do is make the job slow, noisy and conspicuous enough that most thieves move on to something easier. That's the actual goal.
