This Policy Brief outlines early findings from a new study of migrant labour in England’s homecare sector led by Professor Shereen Hussein at the University of Kent. The study forms part of the wider Sustainable Care: connecting people and systems research programme, and draws on: • A review of existing evidence about migrant care workers in the UK • A survey of 32 people with expertise and knowledge of social care and migration, focused on issues of demand and supply • Interviews with 25 migrant homecare workers • Ongoing comparative analysis of the sustainability of migrant care work in eight countries, to be reported separately. Data were collected, in 2019-2020, at a time of uncertainty associated with the UK’s departure from the European Union, its future immigration system, and ongoing challenges in adult social care.
