UK businesses face billions in losses due to stress-related absence

With workplace stress costing UK businesses billions each year, HR consultants are calling for urgent action to tackle the root causes of poor mental health in the workplace.

According to recent figures:

• £51 billion – The annual cost of poor mental health to UK employers (Deloitte).
• £28 billion – The cost of stress-related absence and burnout to the UK economy (AXA)
• 16.4 million – The number of working days lost due to stress, depression or anxiety in 2023/24 (HSE).

With April 2025 marking Stress Awareness Month, these numbers highlight a growing crisis in UK workplaces. Stress-related absence is not just an HR issue – it’s a business issue that directly impacts productivity, profitability and employee retention.

“Too many businesses treat stress as an individual problem rather than addressing the systemic workplace issues that cause it,” said Tara Anstee, HR consultant at Zest HR.

“Investing in mental health support isn’t just the right thing to do; it’s a strategic move that improves engagement, reduces absenteeism and enhances overall business performance.”

Where should businesses start?

The key to reducing workplace stress is tackling its root causes. Common stress triggers include:

• Excessive workload – Unrealistic expectations and chronic overworking lead to burnout.

• Poor management – Ineffective or unsupportive leadership is one of the biggest stress triggers.

• Job insecurity – A lack of role clarity and uncertainty about the future creates anxiety.

• Toxic work culture – High-pressure environments, lack of recognition and workplace conflict drive stress.

By identifying and addressing these factors, businesses can foster a healthier, more productive work environment.

Take action today

Businesses looking to create a proactive strategy for reducing workplace stress can start by assessing their current practices and making employee wellbeing a leadership priority.

"There’s no one-size-fits-all solution, but every business can take meaningful steps to improve mental health at work," added Tara.

"The first step is understanding the challenges your employees face. From there, you can build a workplace that supports both wellbeing and performance."
