100 UK-listed companies assessed and ranked into one of five performance tiers
11 industry sectors represented
Combined workforce of 4.5 million people1
The Covid-19 pandemic brought mental health and employee wellbeing into focus for many employers, highlighting the importance of psychological safety and support in the workplace. Several years on, these issues remain firmly on the agenda. But organisations are facing a new wave of challenges, including economic uncertainty, geopolitical instability, rapid technological shifts and the escalating effects of climate change.
Now in its fifth year, the CCLA Corporate Mental Health Benchmark – UK 100 has become an important framework for companies looking to strengthen their approach to managing and reporting on workplace mental health. It is also an accountability tool for investors seeking to understand how businesses are addressing the risks and opportunities associated with employee mental health.
Benchmark objectives
- Assess the extent to which companies provide the conditions at work for people to thrive.
- Provide investors with an accessible way to evaluate and compare corporate practices.
- Encourage greater transparency, to help remove stigma and ensure corporate efforts are focussed on activities that support the mental health of people at work.
Key findings for 2026
- 20 companies improved their tier, while 55 increased their overall score
- 26 companies rank in the top two performance tiers, compared to 10 in 2022
But it’s not all good news…
- 59 companies’ tier ranking remains unchanged on last year
- 16 companies fell a performance tier
- 15 companies ranked in the bottom-performing tier (tier 5)
Five-year outcomes and impact
Of the 220 companies assessed each year, 77 have improved their performance tier – to the combined benefit of 5.5m employees worldwide.2
Why does mental health matter to investors?
Failing to address workplace mental health isn’t just a moral issue, but a financial one. In England alone, mental ill-health at work is estimated to cost nearly £110 billion each year through staff turnover, presenteeism, economic inactivity and sickness absence.3 Across Great Britain, 22.1 million working days were lost to work-related stress, depression and anxiety in 2024/2025.4
Through engagement and advocacy, investors have the opportunity not only to improve people’s lives but also to improve the bottom line of the companies in which they invest.
About the benchmark
At CCLA, we aim to be a catalyst for change in our industry and to kick-start investor action on underserved sustainability risks. Doing so successfully requires us to think outside the confines of our investment portfolios. Rather than just trying to change one company at a time, one topic at a time, we also aim to change the norm – the expected way in which business is done.
The CCLA Corporate Mental Health Benchmark is designed to incentivise major employers to create the working conditions in which every individual can thrive. It is also designed to open a conversation with investors about the role of mental health in assessing the overall health of a business.
This benchmark assesses the public disclosures of 100 UK-listed companies, selected according to market capitalisation and workforce size.5 This year’s report also includes a trend analysis, examining how corporate approaches to workplace mental health have evolved since the benchmark was launched in 2022. Drawing on five years of data, the analysis offers insight into the extent to which workplace mental health is becoming embedded within governance, strategy and workforce management across the largest UK-listed companies. It highlights areas of sustained progress, identifies persistent gaps in performance, and explores broader trends in corporate disclosure and management practice.
