Why do all major price comparison sites all use the same results provider?

Dave_KS

Whilst researching same insurance quotes from all the major online comparison sites all my results came back via a  company called "Simply Business". I had a follow up call from their rep and out of curiosity i asked a. why does it all come back to one company and where is the market competitiveness price wise in that that.  It seems that they claim to be "The largest clearing house with all the records needed for all the comparisons sites"  For fairness  I felt that something did not feel right so i actually stood by my present insurer who was actually much cheaper on like for like and who did not appear in any comparison listings.
