There are also companies known as "insurance consultants". Like a mortgage broker, these companies are paid a fee by the customer to shop around for the best insurance policy among many companies. Similar to an insurance consultant, an "insurance broker" also shops around for the best insurance policy among many companies. However, with insurance brokers, the fee is usually paid in the form of commission from the insurer that is selected rather than directly from the client.

Neither insurance consultants nor insurance brokers are insurance companies and no risks are transferred to them in insurance transactions. Third party administrators are companies that perform underwriting and sometimes claims handling services for insurance companies. These companies often have special expertise that the insurance companies do not have.

The financial stability and strength of an insurance company is a consideration when buying an insurance contract. An insurance premium paid currently provides coverage for losses that might arise many years in the future. For that reason, a more financially stable insurance carrier reduces the risk of the insurance company becoming insolvent, leaving their policyholders with no coverage (or coverage only from a government-backed insurance pool or other arrangements with less attractive payouts for losses). A number of independent rating agencies provide information and rate the financial viability of insurance companies.

Insurance companies are rated by various agencies such as AM Best. The ratings include the company's financial strength, which measures its ability to pay claims. It also rates financial instruments issued by the insurance company, such as bonds, notes, and securitization products.

The insurance industry in China was nationalized in 1949 and thereafter offered by only a single state-owned company, the People's Insurance Company of China, which was eventually suspended as demand declined in a communist environment.
