The implementation of the Social Services and Well-being (Wales) Act 2014 is widely seen as having the potential to create a more mixed economy of provision through user led services and greater use of social models. In particular, Article 16 places a duty on local authorities and those commissioning services to promote the use of social enterprises and other delivery mechanisms. As the Welsh Government wish to increase the role of social business models, they are seeking evidence from elsewhere on how best to do this and ensure the sustainability of these models. Subsequently, the Welsh Minister for Health and Social Services and the Public Policy Institute for Wales (PPIW) recently commissioned Ross Millar, Kelly Hall and Robin Miller at the University of Birmingham to explore the existing evidence base and report on the benefits and challenges of using social enterprise, micro enterprise and co-operatives in the health and social care sector.
