Right to work checks, and why security contractors get asked twice

Right to work checking is a duty on every UK employer, not a security-specific one. What is specific to this sector is how often you are asked to demonstrate it — by clients during contract mobilisation, during assessments, and whenever a contract changes hands.

Where the evidence goes missing

The check itself is usually done. The evidence is what disappears, and it tends to disappear for structural reasons rather than careless ones.

  • The check happens at onboarding, in a different system from the operational record
  • A follow-up check is due for time-limited permission, and nothing prompts it
  • An officer transfers in from a subcontractor, and the check is assumed rather than repeated
  • Documents are held as email attachments rather than against the person

Time-limited permissions

Where someone's permission to work is time-limited, a follow-up check is required before it expires. This is the same shape of problem as licence expiry — a date, sitting in a file, with nothing attached to it that raises its hand. The fix is the same: put the date somewhere that will prompt you.

Government guidance on acceptable documents and the checking process is updated regularly, including the rules on digital and online checks, so confirm the current Home Office guidance rather than relying on the process you set up two years ago.

Key takeaways

  • Right to work checking is a universal employer duty; the frequency of being asked to prove it is what is sector-specific
  • Evidence goes missing structurally, not carelessly — usually because it lives away from the person record
  • Time-limited permissions need a follow-up check with a prompt attached
  • Check current Home Office guidance; the acceptable document list and digital checking rules change
