Prior to 1968, there was very little statutory intervention in the contractual relationship between business organizations and their customer, with a few exceptions such as those that came within the scope of the Food and Drugs Act 1955. Since the 1960s there has been an increasing amount of legislation designed to protect the interests of private consumers, who legislators have seen as unequal parties to a contract. In recent years EU directives have been incorporated into UK legislation to provide additional duties for suppliers of goods and services. It should be noted that much of the legislation applies only to business-to-consumer contracts and not business-to-business contracts. In the latter case, legislation has often presumed that parties have equal bargaining power and therefore do not need additional legislative protection.
