What is the greatest lever for productivity in your organisation? Tech adoption? Innovation? Performance & talent management? Training? Automation?
A comparison of productivity drivers across UK organisations indicates that the highest average returns for each £1 of investment lie in managing mental health risk, and direct mental health investment (employee assistance and workplace mental wellbeing programmes). Based on this analysis investing in workplace mental health and wellbeing is likely to bring about the greatest gains as a business productivity accelerator.Which leads us to ask, are leadership development initiatives preparing leaders for this challenge? Given 70% of leadership programme directors say they only measure reaction or knowledge, rather than lasting behavior change or outcomes (MIT) and for those who do measure impact, only 15% of organisations report achieving measurable business impact (LEadX Benchmark Report, 2024) we think it is unlikely.
However, organisations are leaving these gains on the table; mental health direct investment accounts for only 1.2% of spend across all main levers of productivity. Most notably, psychosocial risk management, with the highest reported return of between £6 and £9 for every £1 invested, sits at the lowest proportion (just 0.22%) of business productivity investment.
Table 1: Productivity Drivers and Estimated, Annual UK Investment*
| Productivity Driver | Estimated Annual Spend UK | Estimated ROI per £1 Invested | Estimated Annual Return(£Bn) |
|---|---|---|---|
| Human Capital (Training, skills development, leadership, DEI) | £40–45 billion (19.5%) | £3–£4 (≈300–400%) | £120–180bn |
| Technology & Data (IT infrastructure, digital tools, automation, analytics) | £105–115 billion (50%) | £2–£5 | £210–575bn |
| Innovation & Improvement (R&D, operational consulting, process redesign, agile/lean transformation) | £50–60 billion (25%) | £5–£10 | £250–600bn |
| Workplace Systems & Culture (Organisation design, values, behaviour change, inclusive culture) | £3–5 billion (1.8%) | £2–£4 (cultural/ engagement ROI) | £6–20bn |
| Mental Health (Direct Investment – EAPs, mental health benefits, wellbeing programmes, apps) | £3–6 billion (2%) | ≈ £4.70 (470%) | £14–28bn |
| External & Societal Engagement (CSR, ESG, community engagement, policy advocacy) | £2–3 billion (1.14%) | £1–2 (brand and CSR value) | £2–6bn |
| Psychosocial Risk Management (Formal risk assessments, prevention systems, job and organisational design for wellbeing, Health Promotion) | < £1 billion (0.22%) | £6–£9 (emerging HSE/EU- OSHA data) | £6–9bn |
Why this investment gap?
There is a persistent view that the wellbeing gap is caused by the hidden nature of the mental health crisis – employees suffering individual challenges in silence. The conclusion being that we simply need better apps and individual support for workers to take better care of their own mental health and therefore be fit and ready to work.
It may be true that many employees still fear the stigma of mental health and what that might mean for their career prospects, or that they lack the safety to raise mental health concerns in the workplace. However, we don’t need employees to advocate for themselves – the statistics are well known and far from hidden:
- Stress, depression, or anxiety accounts for 49% of all work-related ill health and 54% of all working days lost due to illness, according to the Health and Safety Executive (HSE, 2023).
- The cost to the UK economy is estimated at £56 billion per year, with £18 billion of that shouldered by employers in terms of reduced productivity, staff turnover, and absenteeism (Deloitte, 2022).
Read any organisational mental health blog, article, book, and you will find these statistics (to the point of cliché). Against a backdrop of societal mental health crisis (MHA findings that at least 1:4 adults will suffer mental health challenges over the course of a lifetime) –
the mental health crisis facing British business is not an unknown.
This is a challenge we cannot ignore.
Why then are organisations failing to tackle this critical issue?
We think this boils down to one core issue –mental wellbeing is being treated as an individual challenge to manage, not a systemic opportunity to maximise.
Through our work at the intersection of performance and mental wellbeing, we have observed a critical misconception across many organisations and the way that leaders and individuals talk about mental health – mental health is still perceived to be an individual challenge, a resilience gap, or worse, a personal failing; the causes and effects a private problem, to be dealt with by the individual.
Often, the employer stands benevolently in the background, waiting to provide a helpline, time off, or temporarily to reduce pressure on the individual so that they can seek their own recovery.
However, across diverse organisations in healthcare, policing, professional services, the voluntary sector, construction, and tech, we have found that the mental health challenge facing the UK workforce is systemic; it is a product of systems, processes, ways of working, goals, strategies, reward structures, and the psychosocial context that people work in.
Furthermore, the research is clear on the causes of poor occupational mental health; meaningless work, tech overload, bureaucratic overheads, reduced autonomy, precarious employment, lack of clarity, unachievable or competing targets, and cost of living pressures amount toa systemic, not an individual mental health crisis all of which are within the influence of the organisations we work for.
Short courses of CBT, lunchtime wellness programmes, or notice-board encouragement to look after wellbeing will never be effective if we arepatching people up, simply to send them back into the same exposure, demands, and stressors which contributed to their mental health challenge in the first place.
Even the most capable, motivated individuals will struggle if the environment they work in is fundamentally unsupportive or psychologically unsafe.
In short, organisations are not yet stepping up to play their role in tackling the mental health crisis, and their performance is suffering as a result. We have a UK workforce that is burnt out, sick, and unable to give of its best in creativity, innovation, performance, or collaboration; the powerful human drivers of productivity. That’s because the way in which we build our organisations is causing stress, burnout, isolation, and overwhelm.
Our conclusion? Work is often doing people harm, but it doesn’t have to.
By directly investing in workplace mental health, and managing systemic psychosocial risks, we can unlock productivity gains that can transform the performance of the organisation. Read on to find out how.
