So does a repair count or just a replacement?
Yep, I asked this when I was renewing in December as for some reason it didn't show on my policy schedule, and Elephant re-issued it with the details of the repair claim on. The lovely Welsh lady on the phone said though that they (Elephant, possibly all of Admiral Group too) don't take windscreen claims into account when calculating the premium.
Clearly then there is no statistically significant link between making a windscreen claim and an increased likelihood of making another claim, suggesting that they are completely random events.
