My agent says the company did an "across the board" increase in CT to reflect their actual experience. They are now closer in the level of premiums to other companies active in the state, but still slightly lower. It looks like premium increases are happening everywhere to reflect people driving more, having more accidents due to distracted driving and the high costs of repairs.
I got a lower quote from Progressive but they only do 6 month policies. While their initial pricing is lower, they made it clear that it includes some kind of an introductory discount that will go away after 6 months. They also allow Daughter to be on the policy as a "student away from home" only until she turns 23 (which is in December), after that she needs to be fully rated which will be more expensive as well (she has a clean driving record but as a "student away from home" the rate is cheaper than including her full time). And their rate for umbrella coverage is slightly higher and the condo insurance is significantly higher. My current insurance company does 1 year policies, so I know what my pricing will be for the full year. At most, I will be saving something like $150 by going with Progressive, and I have to go through the hassle of doing all of this again in 6 months.
At this point, I have asked my agent to shop around for me, but it looks like I may be just sticking with what I have...
