We got our insurance through a broker and it's been kind of an annoyance. When they were taken over by another company after having the policy for decades we got a non renewal notice which was fine because we were not interested in doing business through them anyway until we found out that non renewal meant no other insurance wanted us and we were forced to buy a new policy through the broker.
In the United States, brokers are regulated by the state (or states) in which they work. Most brokers are required to have an insurance broker license, which involves taking courses and passing an examination. Each state has different requirements for insurance brokers, which a broker must meet to be licensed in that state. Most states require insurance brokers to take continuing education courses in order to maintain their license.
Insurance brokerage is largely associated with general insurance (car, house etc.) rather than life insurance, although some brokers continued to provide investment and life insurance brokerage until the onset of new regulation in 2001. This drove a more transparent regime, based predominantly on upfront negotiation of a fee for the provision of advice and/or services. This saw the splitting of intermediaries into two groups: general insurance intermediaries/brokers and independent financial advisers (IFAs) for life insurance, investments and pensions.
