Is it permissible to increase the frequency of health screenings for employees in line with age?

Yes, it could be lawful to increase the frequency of health screenings in line with age, but only if the employer can justify such a practice objectively by showing that it is a proportionate means of achieving a legitimate aim. Otherwise, such a practice will amount to direct age discrimination, as it is directly linked to age.

Employers should ask themselves why they want to increase the frequency of health screenings. They may have a legitimate aim of ensuring the health and safety of employees and others, but they would need to show that the practice is a proportionate means of achieving this aim. It is likely that they will need evidence relating to the particular type of work, rather than simply relying on an assumption that older employees are less healthy than younger employees and therefore need to undergo more frequent checks.
