The ROI of Investing in Mental Health Support for Employees

Employee wellbeing is increasingly in the spotlight yet many employers are still asking the question: Is investing in mental health support really worth it? The answer, backed by a growing body of research and real-world data, is a resounding yes.

Supporting your team’s mental health isn’t just a compassionate move—it makes sound business sense. From improved productivity to reduced absenteeism and better staff retention, the return on investment (ROI) for every pound spent can be transformative.

Poor mental health costs UK employers up to £56 billion a year, according to Deloitte. This includes costs related to:

• Absenteeism (people taking time off due to mental health issues)
• Presenteeism (people at work but not functioning at full capacity)
• Staff turnover
• Recruitment and training of replacements

Conversely, businesses that invest in mental health see an average return of £5 for every £1 spent.

Mental health support helps employees manage stress and anxiety, reducing the likelihood of long-term sick leave.

The average cost of absenteeism is around £1,000 per employee per year, which can drop significantly with good support.

Even a modest drop in absenteeism can lead to significant cost savings, especially in small to medium-sized businesses.

Mental health is one of the biggest causes of lost productivity in the UK.

The Health and Safety Executive (HSE) reports that half of all work-related illness is due to stress, depression, or anxiety.

Employees who feel supported and mentally well are more focused, motivated, and engaged. They’re also more likely to go the extra mile and work more efficiently.

High turnover is expensive: Replacing an employee in the UK can cost £5,000–£10,000+, depending on the role.

Investing in wellbeing builds loyalty and reduces burnout, making staff more likely to stay—and reducing the costs of recruitment and onboarding.

A mentally healthy workplace fosters better communication, teamwork, and morale. This creates a positive culture which in turn leads to better performance, and ultimately better business outcomes.

Addressing mental health proactively can help prevent workplace accidents, grievances, or legal claims linked to stress, harassment, or unsafe conditions.

Supporting employee wellbeing doesn’t have to mean costly interventions. Many impactful changes are low-cost or even free:

• Employee Assistance Programmes (EAPs) offering confidential counselling and advice
• Mental health first aid training for managers and team leaders
• Mental Health First Aiders and Mental Health Champions
• Flexible working arrangements to help with work-life balance
• Regular wellbeing check-ins and open conversations about mental health
• Access to mental health apps, helplines or digital resources
• Awareness campaigns to reduce stigma and encourage early help-seeking

Even small steps can demonstrate to staff that their wellbeing matters.

Many companies—both large and small—are already seeing positive results from prioritising mental health. For example:

• BT Group saved £3 for every £1 invested in its mental wellbeing programme through reductions in absenteeism and turnover.
• Unilever reported a 25% improvement in productivity in teams where mental health initiatives were implemented.
• SMEs have also reported better team morale and client satisfaction after investing in mental health support.

Investing in mental health is no longer a “nice to have”—it’s a strategic necessity. Beyond being the right thing to do for your people, it can enhance your bottom line, improve performance, and help futureproof your business.

In short, it’s one of the most financially sound and socially positive investments a business can make.
