Britain's full-time workforce is not short of wellbeing programmes. It is short of knowing they exist. The Mental Wealth Index 2026, conducted by YouGov for Wisdom Wellbeing across 4,249 GB adults including approximately 1,767 full-time workers between 7 and 9 July 2026, found that only 47.5% of full-time workers know they can access mental-health support through their employer. For HR Directors and People leads, that figure reframes the investment question: the problem is not whether support is funded, it is whether the workforce can find it when the pressure peaks.

The survey found that 26.9% of full-time workers do not know whether any support exists, and just 18.5% have ever used it. Those numbers sit alongside official Health and Safety Executive (HSE) data for 2024/25, which estimated that 964,000 workers in Great Britain were affected by work-related stress, depression or anxiety, accounting for 52% of all work-related ill health and 22.1 million lost working days. The Mental Wealth Index describes the substantially larger group sitting just before that threshold.

The visibility gap behind the wellbeing budget

The survey methodology is worth noting before drawing firm conclusions. The research was commissioned by Wisdom Wellbeing, a wellbeing provider with a commercial interest in the findings, and the weighting methodology and margin of error are not published in the summary coverage. The Chartered Institute of Personnel and Development (CIPD), whose annual Reward Management Survey tracks wellbeing benefit take-up across UK organisations, provides a useful cross-reference: its data consistently shows that employee awareness of benefit entitlements, not just their existence, is the primary driver of utilisation. The gap the Mental Wealth Index surfaces is therefore consistent with patterns the CIPD has documented independently.

Read the three access figures together and the pattern warrants serious attention for HR budget holders: more than a quarter of the workforce cannot confirm that help exists, and fewer than one in five has ever taken it up. Low uptake has two plausible readings. Employees may be coping without help, or the route to help may be obscured, stigmatised or simply forgotten after onboarding. The strain data in the rest of the index points firmly towards the second reading.

A workforce coping, with very little in reserve

The strain indicators in the Mental Wealth Index 2026 are the kind of figures that would trigger board-level attention on any operational risk register:

• 38% of full-time workers sit at the anxious end of the scale.
• 43% feel mentally drained often or always.
• 48% sleep six hours or less a night.
• 59% experience some level of financial stress, and 22% are seriously stressed about money.

The HSE figures on work-related stress, depression and anxiety for 2024/25 represent cases that have already escalated to the point of formal absence or clinical referral. The Mental Wealth Index population, those reporting chronic depletion without yet triggering sickness absence, represents the forerunner cohort. Under the Health and Safety at Work etc. Act 1974, employers carry a duty to manage foreseeable risks to workers' health, including psychosocial risks. The Management of Health and Safety at Work Regulations 1999 extend that duty to risk assessment and preventive measures. Neither piece of legislation requires a specific wellbeing app, but both create a governance obligation to demonstrate that the organisation has assessed and acted on psychological risk - an obligation that is harder to meet when the majority of the workforce cannot locate the support that has been put in place.

Where the pressure concentrates

Aggregate figures obscure the segments where a wellbeing offer is most likely to be underperforming. The gender differential is the most pronounced: 51.6% of women report feeling mentally drained often or always, compared with 36.9% of men. Under the Equality Act 2010, persistent health disadvantage that maps onto a protected characteristic raises questions about equitable access to support. Where an organisation's wellbeing provision is structurally harder to access for one group, that design gap carries legal as well as cultural risk.

Younger men present a distinct risk profile. Among men aged 25 to 34, 46.5% report being uncomfortable discussing mental health with their manager. For organisations whose primary referral route runs through the line manager relationship, that channel is effectively closed for close to half of this cohort. ACAS (the Advisory, Conciliation and Arbitration Service) guidance on mental health at work explicitly recommends that organisations make self-referral routes available as an alternative to line-manager disclosure, precisely because the manager route creates a barrier for employees who fear career consequences from disclosure.

Age shapes the picture further. Sleep deprivation affects 59.4% of workers aged 55 and over, while financial stress and burnout run highest among younger employees. A single wellbeing message, pushed through a single channel, is structurally unlikely to reach all three groups with equal effectiveness. Segmented communication, calibrated to the specific pressures facing different workforce cohorts, is a design requirement rather than a nice-to-have.

Why invisible support still costs the organisation

Unused support is not a neutral outcome for the employer. When employees cannot locate help, strain tends to surface later and at substantially higher cost: through sickness absence claims, sustained underperformance, or resignation attributed to something else in the exit interview. The organisation ends up funding both the programme and the downstream consequences of its inaccessibility.

Bertrand Stern-Gillet, CEO at Wisdom Wellbeing, framed the core problem as one of timing rather than investment:

"For too long, mental health in the workplace has been treated reactively; we wait until an employee is signed off with stress before we offer help. This report proves that mental wealth is built through daily, proactive maintenance."

In structural terms, a reactive model is calibrated around the fit note. A preventive model keeps support visible, routine and easy to reach before the fit note becomes necessary. The distinction matters for the HR budget case: reactive spend on absence management and occupational health referrals tends to be less efficient than preventive spend on access and communication, once sickness-absence costs are calculated at the full ONS (Office for National Statistics) labour cost per day rather than at basic pay alone.

What to audit before the next budget cycle

The Mental Wealth Index's own recommendation is to track awareness and fairness of access alongside utilisation rates, rather than treating usage figures as the primary measure of programme performance. Translated into a practical HR audit, that points to five checks worth running before the next benefits review cycle:

• Measure awareness directly. Add a single question to the next pulse survey asking whether employees know how to access mental-health support at their organisation. Compare the result against the 47.5% national benchmark from the Mental Wealth Index 2026. A result below that figure signals a communication problem; a result above it is still not cause for complacency if utilisation remains below 18.5%.
• Segment the results. Break awareness and uptake by gender, age band and team. Strain is unevenly distributed across the workforce, so an aggregate score that looks healthy may conceal the specific groups at highest risk.
• Build referral routes that bypass the line manager. Self-referral, anonymous digital access and peer-support channels all matter for employees unwilling to raise mental-health concerns with their direct manager. ACAS guidance supports this design principle explicitly.
• Connect wellbeing to pay transparency. With 59% of full-time workers reporting some financial stress, wellbeing communications that do not address financial anxiety are missing the most frequently cited pressure. Clear salary bands, predictable pay reviews and access to financial-wellbeing tools belong in the same programme architecture.
• Sustain the message beyond onboarding. Support introduced once in a welcome pack is structurally likely to be forgotten before it is needed. Regular, low-key reminders through intranet channels, team meetings and manager briefings keep the offer in view without requiring repeated full-scale launches.

Visibility as an employer brand and retention signal

Mental-health support shapes how an organisation is perceived in the candidate market, not only how it functions internally. At interview stage, candidates increasingly ask about mental-health provision as a concrete proxy for culture rather than as a soft preference. What current employees write in employer reviews tends to reflect whether a programme works in daily practice or exists primarily on the careers page. A material gap between what an organisation funds and what its workforce can actually find represents a retention risk as well as a reputational one.

This is where verified employee intelligence earns its place in the HR toolkit: comparing what the organisation believes it offers against what the workforce actually experiences, team by team and cohort by cohort. The Mental Wealth Index 2026 provides a national reference point. The more granular question, which only internal measurement can answer, is whether your organisation's awareness gap is narrower or wider than the national 47.5%.

The Mental Wealth Index 2026 does not suggest British employers have stopped investing in mental health. It suggests that for most full-time workers, the investment is not visible enough to use. The CIPD's reward and wellbeing benchmarking, the HSE's sickness-absence statistics and the Access to Work framework maintained by the Department for Work and Pensions all point in the same direction: the governance and commercial case for measuring awareness, not just spend, has rarely been stronger. Closing that gap starts with a measurement most organisations have not yet taken: how many of your people know where help is.
