Mental Health First Aid vs Physical First Aid: What the Law Requires
Updated 28 September 2026 · 3 min read · Amber Training
Reviewed for accuracy by a qualified Amber Training first aid trainer.
Mental health first aid is not a legal requirement for UK employers; physical first aid is. The Health and Safety (First Aid) Regulations 1981 require adequate first aid for injury and illness at work, delivered by people trained in skills such as CPR, defibrillator use and bleeding control. HSE's guidance also encourages employers to consider mental health when assessing their first aid needs, and many choose to train mental health first aiders as well. The two do different jobs, and one cannot stand in for the other.
What the law actually requires
The first aid regulations are about physical emergencies: someone collapses, bleeds, chokes, is burned or is injured. If your first aid needs assessment says you need a trained first aider, that person needs a physical first aid qualification: Emergency First Aid at Work for most lower-risk workplaces, or First Aid at Work for higher-risk or larger ones.
Mental health sits under a different part of the law. Employers must assess and manage risks to health at work, which includes work-related stress, under the Management of Health and Safety at Work Regulations 1999. That duty is about how work is organised and managed, not about appointing a particular type of first aider.
What HSE recommends
HSE's first aid guidance asks employers to consider mental health alongside physical injury and illness when working out their needs. That can mean training some people to recognise and respond to someone in distress, clear routes to professional support such as an employee assistance programme, and managers who know how to have supportive conversations. It is a recommendation to think about it, not a mandated role.
The key difference in the room
A physical first aider can keep someone alive in the minutes before an ambulance arrives: CPR, a defibrillator, controlling severe bleeding, clearing a blocked airway. A mental health first aider is trained to spot signs of mental ill health, start a supportive conversation and signpost to professional help. Both are valuable. But in a cardiac arrest, only one of them can act, which is why the law requires it.
A sensible approach
- Meet the legal duty first: trained physical first aiders in the numbers your assessment calls for (see how many you need).
- Add mental health support proportionate to your organisation: a wellbeing policy, access to professional support, trained managers, and mental health first aiders if you choose.
- Write both into your policies, so staff know who to go to for what (see what a first aid policy should include).

Frequently asked questions
Is mental health first aid a legal requirement in the UK?
No. There is no legal requirement to appoint trained mental health first aiders. The legal first aid duty, under the Health and Safety (First Aid) Regulations 1981, is about physical injury and illness. HSE's guidance does encourage employers to consider mental health when assessing their first aid needs, and employers separately have to manage risks such as work-related stress.
Can a mental health first aider replace a physical first aider?
No. Mental health first aid training does not teach CPR, defibrillator use, bleeding control or the other skills the physical first aid duty is about. If your needs assessment calls for a trained first aider, that person needs an Emergency First Aid at Work or First Aid at Work qualification.
Should I train mental health first aiders as well?
Many employers choose to, as part of a wider approach to wellbeing, alongside good management practice and access to professional support. It is a sensible addition to physical first aid, not a substitute for it.
