In regards to insurance myths, the most common myths I see all the time are:
1. Insurers will refuse to pay if you have no MOT (not the case - more complicated than that)
2. We're not wise to people putting their 18 year old son/daughter on the policy to reduce premiums - most insurers will now rate on the highest risk driver so it makes no difference
3. Reject the first offer - by all means waste your time for the sake of it. We're obliged to use trade publications to value a vehicle. They are occasionally incorrect, and a simple check of Autotrader will confirm this one way or the other. When I do settle claims (as I am a fraud handler first and foremost), I rarely get a dispute over the valuation, and when I do, 90% of the time I do not increase. People go to the ombudsman, and they subsequently reject the complaint.
Don't get me wrong, there are some ****-poor companies out there - generally anyone who passes the claims side of things to India to cut costs - they have no clue, and annoy me more than anyone. These companies continually make losses as they have no idea how to deal quickly and efficiently with claims. The company I work for makes a profit year on year, and our customer base increases each year as well.
You see the Norwich Union (or whether they are called) advert saying they've taken back 60000 customers - doesn't state how many 100's of thousands they have lost though does it?
There are many myths about insurance - I bought into a lot of them before I starting working for insurance companies. People believe what they want to believe - if my answers are ignored, rejected or mocked, fine - I know what I'm talking about and I hope it comes back to bite people in the ass
