Mental Health Policy UK: Workplace Stress Guide 2026

What this document is

A Mental Health and Stress Policy is an internal document that explains how an employer approaches psychological wellbeing at work. It usually covers the organisation's commitment to reducing avoidable stress, the steps it takes to spot problems early, the support available to staff who are unwell, and the responsibilities of line managers.

Unlike a contract of employment, it is typically not legally binding in itself, but it sits alongside the employee handbook and helps evidence that the employer is taking reasonable steps to meet its duties under health and safety law and the Equality Act 2010. For many smaller employers, the policy also acts as a practical handbook: it tells a stressed employee who to talk to, tells a manager how to respond, and tells HR how to record and review incidents.

Putting it in writing signals that mental health is treated with the same seriousness as physical safety. It also gives the business something to point to if a grievance, tribunal claim, or HSE query ever arises.

How to use this document

1. Map the pressures in your workplace. Before drafting anything, take stock of where stress actually builds up in your business. Talk to managers, look at sickness absence patterns, review exit interviews, and consider anonymous staff surveys. Understanding the real pressure points, whether that is workload, shift patterns, difficult customers, or isolation in remote roles, gives the policy something concrete to address rather than generic statements.
2. Set out clear commitments from the top. A credible policy opens with a statement from leadership about why mental wellbeing matters and what the business will do about it. Commit to specific, workable actions such as reasonable workloads, regular one-to-ones, access to an Employee Assistance Programme if you offer one, and zero tolerance of bullying. Vague promises erode trust, so keep commitments realistic.
3. Define roles and responsibilities. Spell out who does what. Directors own the policy, managers handle day-to-day support and spot early warning signs, HR coordinates referrals and record-keeping, and employees are expected to raise concerns and look after their own wellbeing where they can. Naming roles rather than individuals keeps the document useful as people change jobs.
4. Build in training and support routes. The policy should commit to training managers on recognising signs of poor mental health, having supportive conversations, and making reasonable adjustments. List the support routes available, which may include occupational health referrals, mental health first aiders, counselling through an EAP, and external charities. Give people named points of contact and practical next steps.
5. Review and update the policy regularly. A mental health policy is not a set-and-forget document. Schedule a review at least annually, after any major organisational change, or following a significant incident. Use the review to check that commitments are being met, update signposting, and incorporate feedback from staff. Keep a short version log so you can show how the policy has evolved.
