Insurance-UK?

Hi folks. Anyone from UK found a good insurance plan for OPO? I was planning to subscribe for Protect Your Bubble. It is written in T&C that they provide with refurbished or similar value device if need be, rather than brand new device. How would this refurbished be? Would they cover it if I drop my phone but it is working, or would they say this is "just a cosmetic issue"? Any thoughts/experience is much appreciated.
