I don't know if people have heard of this scam...the protected no claims bonus.
Last year, I had an accident, my insurer told me that as I had a protected NCB, my no claims bonus was still intact. So far, so good.
At the next renewal, insurer increased the premium massively (even with the NCB).
I decided to shop around. As far as other insurers are concerned, I made a claim and I had no NCB. The Protected NCB was a contractual agreement with the existing insurer but all bets were off elsewhere. They quoted me equally high premiums.
Anyways, I paid for something that I did not get in the end. Tempted to try the Ombudsman and will let you know if/when I get a response in a year or two.
Lesson : Beware!!!!
