Although my experience of accident management companies is limited to using them via a corporate lease plan, I have to say that even then, I question their usefulness. A skip delivery lorry recently drove into my brand new lease car. I phoned my lease company to notify them, and they merely put me straight on to the accident management company, who then arranged for a hire car. After this I dealt with the lease company or hire car company directly. Any insurance or payment issues seemed to be dealt with by the latter two (or, in the case of one dispute, my company's HR division). The only further thing the accident management company seemed to do was organise a garage for me to take the lease car to for repair - which I could have done myself. What value do these "management companies" actually add to the process?
