There is growing interest in how enterprises based on co-operative values can help to meet needs relating to welfare and re-energise public services. The objective of this article is to examine critically the intersection of personalised adult social care services and the co-operative tradition, which emphasises mutual aid and value-led enterprise. We do this by retelling the story of personalisation through a co-operative lens, and ground this reading in case studies of two new co-operative enterprises that were supported under a Department of Health programme in England (2006–2009) intended to demonstrate how personalised adult social care could be extended by developing collaborative, co-operative organisational forms.
