When Is a Health Assessment Appropriate?
Employers often ask how pre-employment health assessments can be used effectively without adding unnecessary cost or risk. A good starting point is a simple but important question: when is a health assessment actually appropriate?
Under current legislation, employers must not ask health-related questions until a conditional job offer has been made. Any health information collected must also be relevant, necessary and proportionate to the role. Blanket health questionnaires that ask every candidate the same wide-ranging questions can be excessive and may offer little practical value.
Health information should always be assessed by appropriately qualified health professionals, not HR teams. Occupational health records must be kept separate from HR files, and any screening approach should avoid encouraging medical disclosure directly to HR.
Rethinking pre-employment screening
Many organisations continue to screen all candidates in the same way, regardless of role. While this approach may feel thorough, it often adds cost without improving outcomes. Evidence shows that pre-employment screening is most effective in roles with specific health risks or where health surveillance is required. In non-hazardous roles, screening has limited value and is not a reliable predictor of future sickness absence or work-related disability.
A more targeted, job-specific approach is increasingly recognised as best practice. This focuses on identifying whether a candidate can safely undertake the role and whether any reasonable adjustments may be needed, rather than attempting to identify health conditions that may never affect work.
When a health assessment adds value
A health assessment is usually appropriate for three key reasons. First, to identify whether reasonable adjustments should be considered and how equality legislation applies. Second, to establish a baseline for health surveillance or identify specific work-related health risks. Third, to advise managers on a candidate’s fitness for a particular role.
Modern health assessments are designed to support people into work, not exclude them. Increasingly, assessments focus on enabling individuals to work safely with adjustments, rather than preventing employment because of an existing condition.
Honesty, disclosure and support
Some employers worry that candidates may withhold information or be less than truthful during screening. In practice, dismissal on grounds of dishonesty linked to health is difficult and can carry significant legal risk. Evidence suggests most organisations take a supportive approach if issues emerge later, focusing on adjustments and retention rather than disciplinary action.
The four-question approach
Global Occupational Health Solutions supports a simplified four-question approach at the HR screening stage. This avoids medical disclosure and ensures that any health concerns are referred appropriately to occupational health for confidential assessment.
The four questions are:
Do you have any physical or psychological condition that may affect your work?
Have you ever had a condition that was caused or made worse by work?
Are you currently receiving treatment, medication or investigation?
Do you think you may need any adjustments to help you do the job?
If a candidate answers yes to any of these, referral to occupational health allows the situation to be assessed properly, fairly and confidentially.
How Global OHS can help
Global OHS works with organisations to design proportionate, legally compliant pre-employment processes that reduce unnecessary screening, control costs and focus on what actually matters: fitness for work, reasonable adjustments and safe job placement.
