FAQs

It is likely you will be asked for one of the following by your insurance company:

1. You must have a 5 lever padlock
2. You must have a closed shackle padlock
3. You must have a CEN graded padlock of 3 or more
4. You must have a Sold Secure padlock

It is firstly important to understand that many insurance companies unfortunately have been misguided in terms of what specifications to ask for in a padlock. If in doubt then then simply go for a padlock which is CEN Rated to 3 or more and ideally ‘closed shackle‘ if you can. Still unsure? Read more here.

CEN means Central European Norm. It was devised some time ago when the major padlock manufacturers got together to devise a testing standard. Until then it was confusing since there were plenty of standards for door locks and safes but non for padlocks. Some insurance companies tried to use these standards in relation to padlocks but it simply didn’t work. Still today you may get asked for a specification that simply can’t relate to a padlock and only to a safe or door lock.

There are 6 levels within the grade ranging from general use to maximum security. CEN Level 6 padlocks are rare and for more commercial and consumer purposes 5 is the highest. We tend to recommend anything between 3-5 for high security applications.

Insurance Approved High Security Padlocks

Insurance companies will often ask for a number of different requirements but if in doubt then we advise you to use a European standard known as CEN that ranges from grades 1-6. Please refer to our Insurance Advice Section for more information and ensure you are buying the correct lock. Please note that we also have a page dedicated to sold secure padlocks should you need something that meets that standard. These logos give you a quick idea which locks are insurance approved.
