Have being reading this thread with great interest. No need for me to elaborate on previous posts concerns about what we as sparks "are leaving ourselves open for" as we go about our normal daily work. I am currently going through my first professional liability claim. 25 years with same insurance company. Have deliberately gone with the "top of the range" provider (840.00 euros a year for a sole trader).
In the case I, m involved in the issue has to do with the type of concrete used by the builder which has caused damage to cabling. Here's the interesting bit. Because I personally have not being negligent in any aspect my work, the insurance company feel they have no liability. It has been suggested to me to pursue the concrete supplier.
Not the kind of service I expected, but as "welchyboy" alludes to, its the "way the world is"
