What this page cannot tell you

The register is a list of licence holders and nothing more. It does not record:

  • when the licence was granted, only that the organisation appears in the files we hold
  • any job vacancy, or whether the organisation is recruiting at all
  • contact details, a careers page or a named person
  • why an organisation was removed, or why a rating changed
