Are Cheap Padlocks Any Good | Fine for Gates, Not Sheds
CEN grades, closed vs open shackle, real attack tests. A Wokingham locksmith breaks down when a cheap padlock is fine and when it's a false economy.
Walk into any Toolstation or Screwfix in Wokingham and you'll find a wall of padlocks ranging from £4.99 to north of £80. The £20 ones look substantial. Chunky brass body, shiny finish, hefty in the hand. So the question people actually ask is: does paying more buy you anything real, or is it just a brand premium?
The honest answer is: sometimes a cheap padlock is perfectly fine, and sometimes it's the most expensive decision you'll make. The difference is entirely about what you're protecting and how a thief would approach it.
What the Rating Actually Measures
Padlocks sold in the UK can be tested to the CEN (European Committee for Standardisation) grading system, running from Grade 1 (lowest) to Grade 6 (highest). The test is not vague. It involves timed attacks with progressively more aggressive tools, scored in points.
| CEN Grade | Attack resistance (points) | Typical tools resisted | Realistic use case |
|---|---|---|---|
| 1 | 15 | Light picking, casual pull | Garden ornament gate |
| 2 | 30 | Basic picking, short bolt cutters | Low-value storage |
| 3 | 60 | Larger cutters, hacksaw | Shed, medium-value items |
| 4 | 90 | Angle grinder (short exposure) | Commercial unit, van |
| 5 | 120 | Sustained power tool attack | High-security applications |
| 6 | 150 | Near-professional attack | Rare: specialist installations |
Most padlocks sold at the £15 to £25 price point are Grade 1 or, at best, Grade 2. Some don't carry a CEN rating at all, which tells you everything. A Grade 1 padlock can be cut with bolt croppers you'd buy in Halfords for £12. The padlock cost more than the attack tool. That's worth sitting with for a moment.
Sold Secure is the other rating you'll see. It's a UK-specific scheme, tested by an independent laboratory, with Bronze, Silver, and Gold levels broadly mapping to CEN 3, 4, and 5. If a padlock has neither a CEN grade nor a Sold Secure rating printed on the packaging, assume Grade 1 and treat it accordingly.
The Shackle Problem Nobody Mentions
The body of a padlock gets most of the attention. The shackle, that U-shaped bar, is where most cheap padlocks fail fastest.
An open shackle, the standard design where most of the shackle is exposed, gives bolt croppers a comfortable bite. Standard shackle diameter on budget padlocks is typically 6 to 8 mm. A decent pair of 900 mm bolt croppers will shear that in under five seconds. I've timed it.
A closed-shackle or shrouded design reduces the exposed section of the shackle to almost nothing. There's nowhere for the cropper jaws to grip. This single design change, regardless of price tier, dramatically changes the attack profile. You can buy a decent closed-shackle padlock with a CEN Grade 3 rating, such as the Abus 83CS or the Squire SS50CS, for £25 to £35. That is a different proposition entirely from a £20 open-shackle padlock with no rating.
Shackle material matters too. Hardened steel resists cutting and sawing. Brass shackles look good and resist corrosion but are relatively soft. Budget padlocks with brass shackles are, in practical terms, decorative.
Where a £20 Padlock Is Genuinely Fine
I'm not going to pretend every situation demands a £60 Abloy. There are real scenarios where a cheap padlock is the appropriate choice.
- A garden gate that leads only to the front garden, where there's nothing to steal and the gate itself could be climbed in seconds anyway. The padlock here is a social deterrent, not a security device.
- A pool chemical store or log store with nothing inside worth stealing. Deterrence against casual nosiness is enough.
- An internal door within a building that's already secured by higher-rated locks. A cheap padlock on a boiler room door inside a locked office is probably adequate.
- Temporarily securing a skip delivery or a site welfare unit that's only there for two days.
In these cases, you're not protecting anything a burglar would target. The padlock's job is to keep honest people honest, and a £20 lock does that.
Where It's False Economy
Now for the jobs I actually attend in Wokingham and the surrounding RG40 and RG41 postcodes, where a cheap padlock has cost someone significantly more than the difference in price.
The garden shed with power tools. Emmbrook, Woosehill, Norreys, all of these estates have long rear gardens with timber sheds. A DeWalt or Makita kit in a shed is worth £400 to £1,500. An unrated padlock on a 40 mm open hasp is removed in seconds. The insurance excess alone, typically £100 to £250 on a home policy, exceeds the cost of fitting a proper Grade 3 closed-shackle padlock on a hardened steel close-shackle hasp.
A garage side door. If your garage connects to the house, this is effectively a secondary front door. A budget padlock here is baffling. Fit a minimum of a CEN Grade 4 padlock, closed shackle, on a heavy-duty hasp bolted through the door frame with coach bolts and penny washers, not the screws that came in the packet.
A storage unit or commercial premises in Bracknell or Sandhurst. Business contents aren't usually covered for losses caused by inadequate security. Check your policy wording. Many commercial insurers specify a minimum CEN Grade or Sold Secure Silver rating for padlocks on external doors.
A bicycle. Not strictly a locksmith's territory, but the principle holds. A £15 chain and padlock does not protect a £700 bike. Sold Secure Gold is the floor for anything worth over £300.
The Hasp Is Half the Story
A Grade 5 padlock on a cheap hasp with 30 mm screws into soft pine is not a Grade 5 installation. The weakest point in any padlock setup is where the hasp meets the door or gate. I've seen expensive padlocks defeated in seconds because the hasp pulled clean out of the door frame under one hard kick.
A proper security hasp has concealed fixings when the padlock is locked, so the screws can't be accessed. The fixing bolts should pass through the door and be secured on the other side with a washer and nut, or be installed into a hardwood or metal frame. If you're buying a £40 padlock, budget another £15 to £20 for a proper hasp. Skipping this is like putting good tyres on a car with no brakes.
What to Actually Buy
For a shed with tools worth more than £200, look at the Squire SS50CS (closed shackle, Sold Secure Silver, around £30) or the Abus 83CS/55 (CEN Grade 3, around £35). Both are widely available and represent the point where the cost of the padlock starts to exceed the cost of the attack tool required to defeat it. That crossover point is where security starts to mean something.
For higher-value commercial applications, the Mul-T-Lock MT5+ padlock or the Abloy PL362 are legitimate Grade 5 options, typically £80 to £140. Expensive, yes. Meaningfully harder to defeat, also yes.
For the garden gate leading nowhere in particular? The £12 one is fine.
