ISO 45003 is the international standard that provides guidance on managing psychological health and safety at work. It helps organisations identify, assess, and control psychosocial risks—such as stress, burnout, bullying, and poor job design—within an occupational health and safety framework.
ISO 45003 is not a certifiable standard. It complements ISO 45001 by explaining how to address psychological health risks systematically and proportionately.
What is ISO 45003?
ISO 45003 is published by the International Organization for Standardization. It offers practical guidance for preventing work-related psychological harm and promoting mental wellbeing as part of a safe and healthy workplace.
The standard applies to organisations of all sizes and sectors and is designed to be adaptable to different cultures, roles, and working arrangements, including remote and hybrid work.
What does ISO 45003 cover?
ISO 45003 focuses on psychosocial risk management, covering:
- Identification of psychosocial hazards
- Assessment of psychological health risks
- Planning and implementation of controls
- Leadership, culture, and worker participation
- Communication, competence, and awareness
- Monitoring, review, and continual improvement
The emphasis is on prevention and early intervention, not reactive wellbeing initiatives.
Psychosocial risks explained
Psychosocial risks arise from how work is designed, organised, and managed, and from social factors at work. Common examples include:
- Excessive workload or time pressure
- Lack of role clarity or autonomy
- Poor management practices or change processes
- Bullying, harassment, or discrimination
- Isolation, especially in remote roles
- Inadequate support or resources
ISO 45003 helps organisations manage these risks in the same structured way as physical hazards.
How ISO 45003 fits with ISO 45001
ISO 45003 is designed to be used alongside ISO 45001:
- ISO 45001 sets requirements for an occupational health and safety management system
- ISO 45003 provides guidance on addressing psychological health within that system
Together, they support a holistic approach to worker health and safety.
Key elements of ISO 45003 guidance
Leadership and commitment
Senior leaders are expected to promote a culture that values psychological health and supports open communication.
Worker participation
Workers and their representatives should be involved in identifying risks and designing controls.
Risk assessment and control
Psychosocial risks should be assessed and controlled using a hierarchy of measures, prioritising organisational and job design solutions.
Competence and awareness
Managers and workers should be trained to recognise psychosocial risks and respond appropriately.
Monitoring and review
Organisations should track indicators such as absence, turnover, complaints, and feedback to assess effectiveness.
Who is ISO 45003 for?
ISO 45003 is suitable for:
- Organisations with ISO 45001 in place or planned
- Employers concerned about stress, burnout, or mental health
- HR, health and safety, and wellbeing professionals
- Organisations managing change, growth, or restructuring
- Employers with remote or hybrid workforces
It is particularly valuable where psychosocial risks are significant but poorly defined.
ISO 45003 vs wellbeing programmes
| ISO 45003 | Wellbeing initiatives |
|---|---|
| Preventive and risk-based | Often reactive or individual-focused |
| Organisational controls | Personal coping strategies |
| Integrated with OH&S | Often standalone |
| Evidence-based | Variable effectiveness |
ISO 45003 strengthens wellbeing by addressing root causes, not just symptoms.
Is ISO 45003 certifiable?
No. ISO 45003 cannot be certified.
There are no accredited audits or certificates for ISO 45003. Organisations may state that their practices are aligned with ISO 45003 guidance, but this is not the same as certification.
Benefits of using ISO 45003
Organisations that apply ISO 45003 effectively often achieve:
- Reduced work-related stress and burnout
- Improved engagement and productivity
- Lower absence and turnover
- Stronger leadership capability and culture
- Better compliance with health and safety duties
- Enhanced trust and reputation
Managing psychological health is increasingly recognised as a core business risk and responsibility.
Common misunderstandings about ISO 45003
- “It is a mental health policy” – it is a risk management guide
- “It replaces ISO 45001” – it complements it
- “It is only for office work” – it applies to all roles
- “It focuses on individuals” – it prioritises organisational controls
Understanding these points helps organisations apply the guidance effectively.
How ISO 45003 fits with other ISO standards
ISO 45003 integrates well with:
- ISO 45001 (occupational health and safety)
- ISO 9001 (quality and leadership)
- ISO 31000 (risk management guidance)
- ISO 37301 (compliance management)
This supports integrated governance of health, safety, and organisational risk.
