This article challenges the terms we use to describe the relationship between those who assess and commission service and those who are the recipient of those services. In particular, the article identifies the different terms that have been used in British social work, including 'client', 'customer', 'consumer', 'service user' and 'expert by experience' highlighting their assumptive worlds and the relationships the terms suggest and signify. Service user (the most popular term at present) is highlighted and critically analyzed and found to be increasingly problematic and unable to describe the complexities of the service- recipient relationship. Alternative terms are discussed and found wanting, whilst a possible way forward is suggested to avoid the negative connotations of any one particular term.
