Insurance ratings for security safes can seem quite complicated, but in reality they are quite easily explained.
Safes are not all the same, and some safes are stronger than others. Manufacturers and testing house assess safes using expert locksmiths and all manner of tools, up to-and-including explosives and gas cutting equipment. Following testing, safes are given a rating which represents how long they are able to resist forced or surreptitious entry, and consequently how secure they are.
In the UK this rating is usually expressed as a figure in pounds sterling, and this is called a 'Cash Rating'. A Cash Rating is the level of cover that an insurance underwriter will give to the contents of the safe and can generally be multiplied by a factor of 10X for your valuables.

It should be noted that ratings differ from Insurer to Insurer and your own circumstances can also influence this rating. In many cases the cash rating is only relevant for the purpose of distinguishing between models of safe in order to make a more informed purchase. If a specific cash rating has been specified by your insurer you should always check that they agree with the rating on this page before purchasing a safe.
