As all good things said, try the direct approach.However it may be worth trying other places too. For example, I ve been suffering building problems recently, and Zurich passed the work to Cunningham Lindsay to project manage, and Morgan Ashurst did the actual building and decorating work. Both these firms have national coverage; they probably get a guaranteed flow of work from the insurers in return for a favourable hourly rate. So could be it is guys like this you need to identify and work with as well. As they might be the ones who really control who does the insurance jobs! Good luck!
You have to do a bit of investigating and telephone calls.1. Telephone The Head Offices of Zurich, Axa and any other Big Players. Search the Internet for contact numbers. Ask to speak to someone who deals with repair claims2. Introduce yourself and explain how you can assist them3. Put it in writing along with references
