This guidance has been produced to assist local authorities in the UK (England, Scotland, Wales and Northern Ireland) involved in cross-border placements as described in Schedule 1 to the Care Act 2014. Its aim is to support continuity of care across the UK’s borders by setting out clear values and good practice. A cross-border placement is where an adult is being, or has been, placed by an English, Welsh or Scottish local authority or Northern Irish health and social care trust into accommodation in a different UK country in order to meet their social care needs. The guidance covers the key principles, a general overview of the main legal frameworks, the process and reporting arrangements, handling complaints, disputes between authorities and provider failure. Includes short case studies, examples of case law which may have an impact on the setting up of cross-border placements and a list of references.
