Poor workforce health costs UK £241bn a year, research finds

Research for Vitality's Global Health Index 2026 estimates that poor workforce health costs the UK economy £241 billion annually, equal to about 8% of GDP or £7,000 per worker. Employees working while ill add to the losses because they cannot perform at full capacity. The findings also highlight mental health risks and raise concerns about AI's potential impact on productivity roles.
Vitality’s Global Health Index 2026 puts the annual UK loss from poor workforce health at £241 billion. That equals roughly £7,000 per worker and about 8% of GDP. The figure includes reduced output from staff who work while unwell rather than taking time off.
The study also links elevated mental-health risk to lower focus. Among Gen Z respondents, 80% showed serious psychological distress, and about a third of young women reported depression symptoms. Mental ill health is estimated to cost 30 productive days per person annually, while fewer than one in three UK employers provide counselling or mental-health support. The research does not directly examine AI, though AI competition could affect productivity-based roles.
If these estimates hold, the costs could be felt by workers through pressure to stay on the job while unwell, and by employers through lost output. Younger staff and women may be especially affected if mental-health support remains limited. The findings could prompt discussion about workplace wellbeing measures, though the actual social impact would depend on how firms respond and whether AI changes productivity roles.
