  • the Department for Work and Pensions (which includes Jobcentre Plus and the Pension, Disability and Carers Service), if you claim state benefits, or in Northern Ireland the Department for Social Development
  • your local council, if you claim Housing Benefit, or the Northern Ireland Housing Executive
  • Electoral Registration Officers (to check your identity when you register to vote)
  • the Student Loan Company, if you apply for a student loan
  • your pension provider if you have a personal or stakeholder pension
  • your Individual Savings Account (ISA) provider, if you open an ISA
  • authorised financial service providers who help you buy and sell investments like shares, bonds and derivatives - you can check if your provider is authorised
