Insurance companies are all regulated by the FSA. However, general insurance advisors need not have any particular license or training. Many, however, choose to subscribe to the General Insurance Standards Council (GISC), and you may prefer only to deal with GISC members. They have agreed to abide by the GISC General Insurance Code for Private Customers, which includes formal procedures for making a complaint.
Should an insurance company be unable to meet its commitments, then you may be covered by the Financial Services Compensation Scheme.
Life insurance policies, investments and personal pensions are all covered by the Financial Services and Markets Act, which ensures that all companies are trustworthy and competent. They must also have formal complaints procedures, give you suitable advice, and provide you with certain key information, both before and after you buy.
