E&S insurance must be placed through licensed surplus lines brokers who have access to wholesale markets. Retail agents typically work with these wholesalers to access E&S carriers.
Generally yes, because it covers risks that standard markets won't insure. However, for complex risks, it may be the only option. Premiums reflect the specialized underwriting and higher risk exposure.
Unlike admitted carriers, E&S insurers don't have state guaranty fund protection. Policyholders would become general creditors in insolvency proceedings, which is why carrier financial strength is critically important.
