Sensitive Personal Data

  • The Data Protection Act covers the processing of personal data about a living individual. A special category of personal data, about which the rules of processing are stricter, is called sensitive personal data and relates to the individual's:
  • sexuality;
  • political affiliation & opinion;
  • mental & physical health;
  • religious affiliation & beliefs;
    trade union membership;
  • ethnicity;
  • proceedings for, and disposal of, any alleged and/or committed offence;
  • actual & alleged criminal acts.


Schedule 3 of the Act states that sensitive personal data can only be processed if at least one of the following conditions is met:

  • Explicit consent has been given by the individual;
  • Processing is required to comply with employment legislation;
  • Processing is necessary to safeguard the vital interests of the individual or another person;
  • The information has already been made public by the individual;
  • Processing is necessary in connection with legal proceedings;
  • Processing is necessary for the administration of justice;
  • Processing is necessary for medical reasons;
  • Processing is necessary for ethnic monitoring.

Additional conditions apply to the processing of, and research on, personal and sensitive personal data. See elsewhere in this A to Z Guide.
