Negligence on the part of insurance brokers can have severe effects upon clients when they discover their insurance coverage is worthless, which in turn illustrates why retaining a competent insurance broker is so important. In one case, Near North Entertainment Insurance Services provided alternative rock band Third Eye Blind with a commercial general liability (CGL) insurance policy that excluded coverage for the "entertainment business". After insurance coverage for a lawsuit was denied because Third Eye Blind was and is, after all, in the entertainment business, the California Court of Appeal ruled in a published opinion that the broker had a duty to advise the band it needed something more than a basic CGL policy.
Insurance broker became a regulated term under the Insurance Brokers (Registration) Act 1977 which was designed to thwart the bogus practices of firms holding themselves as brokers but in fact acting as representative of one or more favoured insurance companies. The term now has no legal definition following the repeal of the 1977 Act. The sale of general insurance was regulated by the Financial Services Authority from 14 January 2005 until 31 March 2013 and by the Financial Conduct Authority since 1 April 2013. Any person or firm authorized by the Authority can now call themselves an insurance broker.
