What is a Mental Health First Aider — and what do they actually do?

“We’ve appointed Mental Health First Aiders” is an increasingly common line in job ads and staff inductions. But what does the role actually involve — and just as importantly, what doesn’t it?

The role in one paragraph

A Mental Health First Aider is a colleague trained to recognise the signs that someone may be experiencing poor mental health, respond with a calm, non-judgemental conversation, and guide the person towards appropriate support — their GP, occupational health, an employee assistance programme, or emergency services in a crisis. The role is deliberately modelled on physical first aid: immediate, initial help until the right support takes over.

What first aiders are trained to do

On a two-day qualification course, participants learn to:

Spot early warning signs of common conditions — depression, anxiety, and also less common presentations like psychosis
Start a conversation with someone they’re worried about, and listen without judging or problem-solving
Follow a structured action plan in a crisis, including when someone has thoughts of suicide or is self-harming
Signpost to professional and community support
Protect their own wellbeing while supporting others

What the role is not

This is the part good training spends real time on. Mental health first aiders:

Don’t diagnose. Noticing that someone seems to be struggling is not naming a condition.
Don’t treat or counsel. The role is a bridge to support, not the support itself.
Don’t carry ongoing cases. Being someone’s permanent confidant leads to burnout; the role is initial help and signposting.
Aren’t responsible for outcomes. They offer help; whether and how it’s taken up is not theirs to own.

Boundaries protect the person being helped and the first aider.

Making the role work in a workplace

Organisations that get value from mental health first aiders tend to do a few things well:

Choose volunteers, not conscripts. The role needs genuine willingness.
Cover the workforce sensibly. A common benchmark is one first aider per 10–25 staff, spread across sites and shifts — mirror your physical first aid ratios as a starting point.
Make them visible. Posters, intranet pages and introductions at inductions — people can’t turn to someone they don’t know exists.
Support the supporters. Regular peer check-ins for the first-aider network, and a refresher course every three years.
Fix the causes too. First aiders help people; they don’t fix workloads, poor management or toxic culture. Treat the role as one part of a wellbeing strategy, not the whole of it.

Thinking about becoming one?

You don’t need any background in mental health — just willingness to listen and to learn. Most people find the training personally valuable far beyond work. Browse the courses, check typical prices, or see upcoming dates including live online courses you can join from anywhere in the UK.
