I found when I was looking that 4 years seems to be a standard for everyone. I got my protected claims insurance and then immediately started using it (as luck would have it). However I think they simply claw back some of the money they spend by increasing the amount of excess you pay on each claim. I paid �350 on my second protected claim instead of my usual �100 that I would have paid for an unprotected claim. This means that I paid �250 over what I would have paid, I wonder if I would have paid an extra �250 for the increased insurance premium if I had lost my no claims for the year? Just a thought!
