The Civil Service do not gather information on individual medical conditions.
United Kingdom Security Vetting (UKSV), the UK’s centralised vetting provider, does not collate or report on specific medical conditions. This is due to vetting confidentiality. While medical conditions may be collected as part of vetting processes, these are recorded in narrative form. Reviewing the narrative data would require individual examination of many thousands of records. Similarly, it is not possible to collate data for withdrawals or suspensions citing medical factors, due to how this is recorded. Regardless, individuals are not denied clearance, or have clearances revoked, solely on the basis of possessing a particular medical condition. Rather, Vetting Officers, Medical Advisers and other staff build a holistic understanding of each candidate to assess any vulnerabilities or risk factors and make a judgement accordingly.
