I often see it said on here that "most insurance companies don't raise premiums at all for your first 3 points". From playing around with price comparison sites I've always doubted that this was correct - I've tended to see a small but noticeable increase when I add a recent SP30. While this has the usual "rehashed press release" feel of the Torygraph finance pages, it does seem to confirm my impression that the majority of insurers will now increase premiums.
