This article analyses the unfairness concept from the Unfair Commercial Practices Directive (UCPD). It considers why the nature and level of protection is particularly important given the range of coverage of the regime and the Europeanisation agenda. It argues that the UCPD concept provides the potential for a relatively protective approach to consumer decision making. At the same time, it emphasizes that realisation of this potential is partly dependent on recognizing the limits of transparency as a protective tool and in understanding the ?professional diligence? and ?average consumer? concepts in particular ways. It is further suggested that the protective potential of the regime is not necessarily undermined by the ?average consumer? concept or by the ?informed decision-making? paradigm of the general unfairness clause. Indeed, the general clause may be capable of extending the protective effects to some extent. Finally, it is suggested that regulators may have a key role to play in maximizing both the level of protection and the prospects for a genuinely common European approach
