Duty of candour

The duty of candour is the duty to be open and honest with patients when something goes wrong with their care.

Updated 12 October 2026 (1 minute read)

Summary

  • It means telling the patient, apologising, explaining what happened and saying what will be done about it.
  • Every healthcare professional has it as a professional duty.
  • NHS organisations in England have had a legal duty of candour since 2014, introduced after the Mid Staffordshire inquiry.
  • An apology is not an admission of legal liability.

Interview questions
