National Insurance number
The National Insurance number is used as a reference number in the Pay As You Earn system, and also by the self-employed. It is also used in applications for Individual Savings Accounts (ISAs), to check that an individual has opened only one ISA in a tax year.
Social care in England
Social care in England is defined as the provision of social work, personal care, protection or social support services to children or adults in need or at risk, or adults with needs arising from illness, disability, old age or poverty. The main legal definitions flow from the National Health Service and Community Care Act 1990 with other provisions covering responsibilities to informal carers. That provision may have one or more of the following aims: to protect people who use care services from abuse or neglect, to prevent deterioration of or promote physical or mental health, to promote independence and social inclusion, to improve opportunities and life chances, to strengthen families and to protect human rights in relation to people's social needs.
