Britain's hidden productivity drain: workers at their desks but too unwell to function cost the economy £241 billion a year, finds landmark health survey

Poor workforce health costs the UK billions
Poor workforce health is estimated to cost the British economy £241 billion a year in lost output, equivalent to around 8% of GDP, according to new research from Vitality, the health and life insurer, conducted in partnership with Rand Europe. The findings, drawn from Vitality's Global Health and Productivity Index 2026, arrive ahead of the Budget and will intensify pressure on employers and government to treat workforce health as an economic priority rather than a welfare concern
The dominant mechanism is not absence, but presenteeism: workers who are physically at their desks but are not functioning at full capacity. The data finds that an employee with high mental health wellbeing risk would be estimated to lose an additional 30.3 days of lost productivity per year, making them the single largest driver of economic output lost to ill health. Further to this, 66% of workers in the UK report moderate-to-serious psychological distress, whilst only one in four have a formal mental health diagnosis. Combined with the impact of physical health conditions this contributes to an estimated £241 billion a year in lost productivity for the UK economy. The scale of the problem, and its near-invisibility in standard absence data, is a central finding of the report.
The findings reveal a clear generational gradient. More than eight in ten Gen Z workers, those aged 18 to 24, report moderate or serious psychological distress, and young women are disproportionately affected: 35% report depressive symptoms compared with 24% of their male peers. Workers aged 18 to 34 are more than four times as likely to report serious psychological distress as those aged 55 and over.
These findings come against a backdrop of growing concern about youth economic inactivity. The Milburn Review found that more than one million young people are now not in education, employment or training (NEET), placing renewed focus on how employers can support younger workers before health and wellbeing challenges become barriers to participation. The productivity burden identified in this research sits above and beyond those figures, reflecting the additional cost of absence and, in particular, presenteeism among people who remain in work but are not operating at full capacity.
These figures land against a backdrop of rising economic inactivity. The Keep Britain Working Review, led by Sir Charlie Mayfield, found that around 800,000 more people are out of work due to health problems than in 2019, a figure that could reach 1.4 million by 2030 without concerted action.
Despite the scale of the problem and the opportunity that comes from prioritising it, only one in three UK employers offers counselling or mental health support, and access to occupational health and early intervention remains patchy, particularly among smaller employers. The report identifies three higher-impact opportunities for action: automatic enrolment in health support programmes to reach the workers least likely to opt in; board-level accountability for workforce health with metrics in annual reporting; and investment in management capability, where the data shows a gap of nine lost productive days per worker per year between those who feel their manager supports their health and those who do not.
The UK also lags its international peers on the basic infrastructure of workforce health. Just 20% of UK employees are offered health insurance through work, despite this being a gateway to wider health and wellbeing support, including mental health services, and only 13% are offered health screening, against global averages of 33% and 23% respectively.
Neville Koopowitz, Global CEO of Vitality, said: "Britain's search for growth could be aided by paying more attention to one of our greatest productivity issues. This is not people just being off sick, it is people at work, struggling with their health and wellbeing, most likely within organisations that do not measure the health, wellbeing and productivity challenges affecting their workforce.
“It might be an investment, yet it is those employers who are taking the time to understand their employees’ health and associated challenges. and then addressing it that are seeing real returns. The gap between organisations that do this and do it well, will become increasingly visible, with the cost of inaction today already at £241 billion a year.”
Christian van Stolk, Deputy Chief Executive at RAND Europe, said: "The evidence linking health and productivity is substantial, yet absence remains the measure that attracts most attention from employers. The findings from this Global Health and Productivity Index suggest this risks overlooking the larger challenge of presenteeism, where productivity is affected while people remain at work. Left unaddressed, these underlying health issues can become a precursor to long-term absence."
The sample has been weighted to be representative of working populations on the basis of gender, region, ethnicity, and education. All respondents work in organisations with at least 10+ employees, and those who work less than 8 hours per week, are self-employed, or are doing voluntary work have been excluded from the sample.
Additionally, 24 stakeholder depth interviews were conducted with experts, including a spread of business leaders, government and policy experts, public health experts, industry bodies and specialists in academia, think tanks or NGOs. Interviews were recruited from the five key markets. These conversations lasted 45 minutes each and took place through February and May 2026. The interviews resulted in over minutes of expert insight on health, productivity and effective support interventions in the workplace.
