UK faces ‘stress epidemic’ as almost 12 million workers report burnout 

The UK is facing what researchers describe as a “stress epidemic”, with almost 12 million workers experiencing burnout in the past year, according to new findings from productivity and performance coaching provider Avilio. 

Avilio’s nationally representative survey of 1,261 UK workers found that 36 per cent experienced burnout in the last 12 months. Applied to the UK working population, this equates to 11.9 million people living with severe and persistent stress that causes physical, mental and emotional exhaustion. 

Stress is already affecting attendance and performance. Twenty-two per cent of respondents said they had taken time off because of stress, and almost half of those in management roles (46 per cent) said their job is their main source of stress and anxiety. 

The research also points to a workforce at risk of further turnover. Almost a quarter of respondents (24 per cent) are actively looking for a new job, and 29 per cent want to move roles before the end of 2026. Avilio warns that employers face rising costs linked to sick leave, recruitment and loss of experience if stress levels remain high. 

This is the second consecutive year Avilio has tracked burnout. The data shows little improvement. Burnout levels increased from 34 per cent last year to 36 per cent in 2025. Time off for stress fell only slightly, from 24 to 22 per cent. The proportion wanting to change jobs rose from 28 to 29 per cent, while those actively job-seeking dropped from 28 to 24 per cent. 

According to Avilio chief executive, Philippe Masson, employers need to recognise the scale of the problem and act. He said:

“If employers do not look after their teams and they are persistently stressed, then they are more likely to take time off sick and to leave. Organisations risk losing talent to the stress epidemic we are currently experiencing.” 

He added that reducing stress is not only a wellbeing issue but also a business one.

“Investing time and care into looking after teams pays for itself. Employees that are not stressed deliver better results, are more invested in their work and loyal to their employers. Tackling the stress crisis could be a crucial factor in boosting economic activity.”

Avilio was founded in 2020 and provides performance coaching aimed at improving productivity and reducing stress in managers.  

The research was carried out online between 6 and 10 October 2025 by independent agency Opinium, using a nationally representative sample weighted by age, gender, region, employment status and political views.
