I have a physical one when I bought my house, not that the coc is worth anything the electrician in question failed to pick up something pretty bad. I now need to go through the process of reporting the ****.
Some companies are better than others, but these inspection guys rush through their inspections and often only pick up obvious faults. It's impossible to pick up every single little thing in the half hour to an hour they often take to do an inspection. But yeah, the main value of a COC seems to be more administrative than anything else.
