I don't have the breakdown in front of me, but I got my renewal paperwork last week and the combined home/auto premium went up >250$/year, which is ~15%. Which seems nuts, especially for a year in which I moved into a "less accident prone" age band as well.
I need to dig into the details of which parts cost more now, but this is also serving as my impetus to reduce coverage with the age of the car, and look at other insurance providers. So far, seems like jumping ship will be helpful.
