UK residency and security requirements

For meaningful security checks to be carried out, individuals need to have lived in the UK for a sufficient period of time. Please note that this role requires Security Check (SC) clearance, which would normally need 5 years’ UK residency in the past 5 years. Candidates must also hold or be prepared to undergo NPPV3 clearance. However, in exceptional circumstances security clearance applications for candidates who have been present in the UK for at least 3 of the last 5 years may be considered. Failure to meet this residency requirement will result in your security clearance application being rejected.
