A couple of things I've learned from working for State Farm:
- If SF's rates are going up, chances are very good that other competing companies' rates are going up as well. SF tends to be ahead of the curve in regards to rate increases. The local SF office is almost never told about a particular client's rate increase - those are decided at the corporate level. Some rate increases are due to changes in state laws or policy in regards to insurance companies.
- Always talk to your agent, and try to get a face-to-face meeting. Some agents will work harder for you if you come in; others won't.
- In regards to switching companies, we found that GEICO didn't particularly have the best practices. If you threaten leave GEICO for anyone, they'll promise to reduce your payments. To me, if I'm that important of a customer, you should be looking to reduce my payment without me threatening to leave. That's just me; I know some people are more price-sensitive.
- Somethings to consider for vehicle rate increases: yearly mileage change, safety ratings of the vehicle (which can change over time), policy bundles. If you know you're driving less miles/year than when you started the policy with your agent, get it revised and see if that changes it. Most vehicles covered by SF are rated at 10,000/year if the customer doesn't say anything or isn't sure about their yearly mileage. If you're only paying for auto with SF, they do offer discounts for bundling homeowners and certain life insurance policies.
I no longer work for SF, but keep my policies there. My rates have increased, but not to the point that I will look elsewhere. Ultimately, I've found that if you own multiple vehicles (3 or more), you're going to paying a bit for the coverage. Just trying to be honest.
