I had a quote waiting on Admiral for a few weeks until I go pickup my zed and overnight, without any changes, it went up £300. Phoned them up and they're looking into it but I went on today and it's gone back down?! Crazy!
I forgot to add my PC30 "conviction" (stopping too close to a pedestrian crossing to let my girlfriend put something in a post box), and that's added 50% on to my quote, not happy!
