The rule for best inside this set
The score is the amazon.co.uk star rating times 20. Review count does not add points. It breaks a tie. Diyife and NovLock both sit at 4.7. Diyife has 1,993 reviews and a stated body around 52 mm with an 8 mm shackle, so it is the top pick. NovLock has 883 reviews and the same stated diameter, so it stays the alternative. Best value is a price rule: the lowest price among listings at 4.4 or above with at least 1,000 reviews. That is the GRIFEMA at about £3.78, 4.4 from 10,461 reviews.
Heavy duty does not win, and a larger body does not win. A maker’s private scale does not win either. The Squire CP50 publishes 5/10+ on Squire’s own scale, and the maker’s page describes an 8 mm shackle. That note is not a BS EN 12320 grade, the amazon.co.uk listing does not print a shackle diameter, and it does not replace the star rule. The question order for fit and grade is the padlock buying guide.
Top pick, the Diyife
The top pick is the Diyife, about £13.99, a 4-digit combination with a stated 8 mm hardened 304 stainless shackle. The bullet size is 52 x 26 x 84.5 mm. Another line reads as a 51 mm cube, so measure the hasp. It is for a shed or gate hole that actually takes that body. Buyers set the code without a key to lose, and one shed review covered about two months without a fault. The body is heavy, at 270–280 g. High stars mean people could set the code and live with the size. They do not mean the hoop was tested against bolt croppers.
Skip it if you need a closed shackle, a marine-stated lock, or any BS EN 12320 grade you can show an insurer. NovLock, about £14.99, matches the star score and the 8 mm line with fewer reviews. Same diameter, smaller sample, slightly dearer. The tie-break is that review count, not a laboratory result.
Best value, the GRIFEMA
The best value is the GRIFEMA at about £3.78. It has the most reviews in the set, and the shackle diameter is not stated. It sits in the entry band of about £3.80 to £8. Under £10 you are buying a deterrent, not a published grade 3. Review volume is what a commercial search page rewards. On this comparison it wins the price rule, and nothing else.
Gym-locker use is the job buyers describe. Outdoors, reviewers say it needs regular lubricant, and two successive locks stopped opening after about six months. If you needed a stated 8 mm hoop, this is the wrong row. If you only wanted the cheapest 4-digit lock with a huge review pile, this is the lock that pile belongs to, and it is still ungraded.
Where the stars and the big body point instead
JMIATRY, about £20.99, with 3.2 from 13 reviews, is the other lock at the top of this set’s prices. The body is about 74 mm and the seller states a 12 mm shackle, so it looks like the heavy-duty buy. Reviewers say the pair is not keyed alike. A thicker hoop on an ungraded listing, with that review score, does not overturn the rule.
The SEPOX pair, about £9.97, is sold as keyed alike, and that job belongs on the combination versus keyed padlock page, not as another badge here. The Squire CP40, about £13.00, is the locker-sized Squire. Do not hang it on a gate because the brand matches the CP50. SharkByte, NAGE, YIKI, the xdg pair sold keyed to differ, and Solvica illustrate the shelf. Reviewers say one Solvica lock arrived. They do not replace the written rule.
Who should buy none of these twelve
Buy none of these twelve if your shed advice is two closed-shackle padlocks, which is what West Yorkshire Police describes, or two hasps with hidden fixings, which is what Secured by Design describes. None of the twelve is a closed shackle. A weatherproof combination from this shelf can lock a low-risk latch. It does not meet that pattern. The positions, the weather and the reason for leaving the set are on the padlock for a shed and gate page.
Also skip both picks if an insurer has named a grade you cannot see on the listing. Do not invent a rule that every shed policy names a grade. The policy is the source. If you need a published CEN grade or a closed shackle, the next step is a different model from a shop that states the mark. ABUS and Yale locks that appear in other UK articles were not captured here, so they are not picks on this page.
Common questions
What is the best padlock in this amazon.co.uk set?
The top pick is the Diyife 52 mm combination padlock at about £13.99. It has 4.7 from 1,993 reviews, a stated body around 52 mm and a stated 8 mm shackle. NovLock matches 4.7 and the diameter with 883 reviews, so the larger sample takes the place. The Diyife is an open-shackle 4-digit lock. The listing does not state a BS EN 12320 grade or a Sold Secure mark.
Which one is the best value?
The GRIFEMA at about £3.78. It is the lowest price among listings at 4.4 or above with at least 1,000 reviews, here 4.4 from 10,461. The shackle diameter is not stated, and there is no security grade on the page. Under £10 you are buying a deterrent. It suits a gym locker if you can oil it, not a hasp that needs a stated hoop thickness.
Why is the lock with the most reviews not the top pick?
GRIFEMA has 10,461 reviews, the largest pile in the set, and that pile is why it is the best value on the price rule. The top pick is the 4.7 line with a stated 8 mm shackle and the larger of the two samples, which is the Diyife. Stars record that people could use the lock. They do not record a cropping test, and a review count does not add points to the score.
Is the Squire CP50 a CEN or Sold Secure padlock?
Not on the evidence in this set. Sold Secure Bronze, Silver, Gold and Diamond map to CEN grades 3 to 6. The CP50 listing does not state those marks. Squire’s 5/10+ is the maker’s own scale, and the amazon.co.uk page does not print a shackle diameter. Treat that silence as ungraded. The CP50 is not the top pick on the star rule used here.
Is the JMIATRY the heavy-duty one because it is larger?
No. A 74 mm body and a stated 12 mm shackle make it the large keyed pair at about £20.99, with 3.2 from 13 reviews. Reviewers say the two locks are not keyed alike. Size without a stated grade, and with that review record, does not beat the documented 8 mm combination that takes the top pick. Do not buy it as the heavy-duty answer.
Who should skip both picks?
Anyone who needs two closed shackles on a shed, a marine-stated lock, or a grade an insurer has already named. None of those requirements is met by the Diyife or the GRIFEMA. A school locker or a low-risk family gate is the job these two can actually do, and even then you still measure the staple before you drill. A shed that must follow the police pattern is a different purchase.
