In England and Wales permanence has been defined in legislation as
“The long-term plan for the child’s upbringing and provides an underpinning framework for all social work with children and their families from family support through to adoption. The objective of planning for permanence is therefore to ensure that children have a secure, stable and loving family to support them through childhood and beyond and to give them a sense of security.”
