The Hidden Cost of Waiting Too Long to Use Mental Health Benefits
Most people who are struggling at work don’t say so. They come in, they get through the day, and they manage it quietly, often for far longer than anyone around them realises. By the time it becomes visible, through a missed deadline, a longer-than-usual absence, or a conversation that finally breaks the silence, the issue has usually grown well beyond what it was when it started.
Supporting mental wellbeing at work has never mattered more. Most UK employers now offer some form of mental health support, through EAPs, counselling services, or broader wellbeing initiatives. Yet too many employees continue struggling in silence long before they reach out for help, if they reach out at all.
Drawing on recent research and industry data, this article explores the hidden cost of that silence. It examines why employees delay seeking support, what that delay costs both them and the organisations they work for, and what employers can do to build workplaces where people feel safe asking for help before things reach a breaking point.
What’s really driving long-term absence in UK workplaces?
Stress, depression and anxiety now account for 52% of all work-related ill health in the UK, according to the Health and Safety Executive. Around 964,000 workers across Great Britain experienced this in 2024/25, and the figure has stayed above pre-pandemic levels for three years running. This isn’t a temporary dip the workforce is recovering from. It’s a sustained pattern.
Mental health is now one of the leading causes of long-term absence in UK workplaces, and the toll isn’t abstract. In 2024/25, 22.1 million working days were lost to stress, depression and anxiety alone, according to the HSE. That scale of absence brings cover costs, lost output and disrupted teams before anything else is even considered.
Presenteeism costs employers even more. This is what happens when someone is physically at their desk but too unwell, mentally, to really be there, and Deloitte estimates it costs UK employers around £24 billion a year. Add in absence and turnover, and Deloitte puts the total cost of poor mental health at around £51 billion annually. It hides in plain sight in a way absence doesn’t. Someone who calls in sick is at least visible on a spreadsheet. Someone who comes in anyway, distracted and running on empty, often isn’t visible until a mistake happens, or a manager notices that someone who used to seem so capable is now finding everything difficult.
There are harder costs to put a number on too. Concentration slips, decisions take longer, and small errors creep in. People who don’t feel supported eventually leave, taking knowledge with them that, with the right support at the right time, might never have needed to walk out the door.
These hidden costs sit behind the headline figures, and they’re part of why the real question isn’t whether mental health is a problem at work. It’s why so many people are still struggling alone when support already exists for them.
Why do mental health benefits go unused?
Most mental health benefits fail not because they’re absent, but because they’re used too late, often because employees don’t know they exist. According to HCML, 79% of UK employers offer an employee assistance programme, yet only 27% of employees realise one exists in their workplace.
That gap matters more than it might first appear. Employers aren’t withholding support. In most cases, they’ve bought it, budgeted for it and rolled it out. The CIPD reports that 74% of employers now say employee wellbeing is on senior leaders’ agendas, up from 61% in 2020, and 75% say line managers buy into the importance of wellbeing, up from 58% over the same period. Awareness at the top of organisations has genuinely grown.
What hasn’t kept pace is delivery. More than a third of organisations, 37%, still describe their approach as reactive, stepping in only once someone’s already off sick, according to the CIPD. Common measures like counselling and phased return (43% each) tend to switch on after a problem has taken hold. Manager training is rarer, offered by just 29% of employers, even though trained managers report 63% confidence spotting the signs of mental ill health, against 45% without training.
This reactive pattern is becoming a legal exposure too. The Employment Rights Act 2025 reinforces an employer’s duty to treat psychological risks like stress and burnout with the same rigour as physical hazards, and the new Fair Work Agency wants evidence of action, not a policy in a drawer. A benefit nobody knows about is hard to defend as adequate provision if it’s ever challenged.
Many EAPs are mentioned once, at onboarding, and never again. The gap isn’t about what’s been bought. It’s about what happens after, and that part is fixable.
Awareness Does Not Guarantee Action
Knowing a benefit exists isn’t the same as using it. Even among employees who do know their EAP is there, take-up stays low. UK EAP usage typically sits between 3% and 5%, per HCML’s corporate health and wellbeing report.
The reasons tend to fall into three categories.
Practical barriers
Some employees simply find it hard to locate the support or work out how to access it. A login lost, a phone number nobody’s written down, a process that was explained once in an onboarding pack two years ago. It’s enough friction to stop someone reaching out on a hard day.
Trust barriers
Confidentiality concerns run deep, and not without reason. Sonder UK research found that 19% of employees who don’t see their EAP as relevant cite privacy concerns as a significant factor, and a BBC investigation in 2024 found that one major UK EAP provider had allowed corporate clients to listen in on confidential calls without callers’ knowledge. Most providers operate under strict confidentiality standards, and breaches like that one are rare exceptions rather than the norm. But trust, once shaken industry-wide, is slow to rebuild, and an employee weighing up whether to call rarely has the full picture of how rare that exception really is.
Perception barriers
This one varies person to person, but many people don’t yet believe they need help. “I’m not struggling enough” is a common, quiet thought, and it can hold someone back for months. EAPs are often seen as something for a crisis, not for the early stretch where stress is building but hasn’t yet tipped into something more serious.
So, people wait. They hope things will settle on their own, and sometimes they do. Often, they don’t, and the issues that might have been manageable with an early conversation grow into something that needs far more support, support that’s harder to give and harder to receive the longer it’s been left. That’s what the next section explores.
Why Early Intervention Matters
Stress doesn’t arrive as a crisis, it builds gradually, in small shifts that are easy to miss at first. Someone gets more tired, then more irritable, then they’re lying awake at 2am rerunning tomorrow’s meeting. Most people slide along that spectrum long before anyone would call what they’re going through a crisis.
That gradual build is where preventative support and crisis intervention part ways. Reaching someone early usually means a short conversation or a few sessions of counselling. Reaching the same person three months later, once sleep has broken down and concentration has gone, usually means extended time off and a longer road back.
PAM Group’s 2025 Health at Work Report shows the gap clearly. Proactive wellbeing support makes employees more than twice as likely to take no sick leave, and eight times more likely to call themselves highly productive. Yet while 57% of employees want access to mental health counselling, only 22% currently have it, and just 11% used it in the past year, a wide gap between what people want and what they can actually reach.
A delay in getting support can compound quickly. What might have been manageable with an early conversation can, in PAM Group’s findings, develop into a longer absence the longer it goes unaddressed. Sleep worsens, concentration drops, and small problems start to feel unmanageable. The next section looks at how that gap starts to close.
Moving from Passive Provision to Active Promotion
Support has to stop sitting quietly in the background and start showing up where people actually are.
That starts with communication, and not the once-a-year kind. An EAP mentioned at onboarding and never again might as well not exist two years later. Employers seeing real engagement talk about their benefits repeatedly, through emails, team meetings and manager conversations, framed not just as “this exists” but “this is what it can help with”: a hard few weeks, money worries, a difficult conversation at home, not just a diagnosable crisis.
Clear objectives matter too. Without a baseline to measure against, there’s no real way to know if a benefit is working or just sitting there. A simple usage target gives HR something to act on rather than guess at.
It also helps to ask employees what they actually want, rather than assuming demand matches what’s already on offer. Listening through surveys, feedback, or conversations with managers tends to reveal gaps that a benefits audit alone won’t show.
None of this works without a culture where talking about mental health is normal rather than risky. Managers who are trained to spot the early signs report far more confidence having those conversations, and that confidence shapes whether someone speaks up early or waits until they can’t avoid it any longer.
What This Means for Employers
The research cited throughout this article suggests the issue is not a lack of provision. Most employers already have support in place.The gap is in how visible and consistently present that support is in everyday working life, so someone struggling quietly in week two isn’t left to wait until week twelve before they feel able to reach out.
Employers don’t need to build something new to close that gap. They need what already exists to actually reach people while it can still make a difference, which mostly comes down to talking about it more, and more honestly, than most workplaces currently do.
