What is Mental Health First Aid?

· 2nd August 2026

When an employee has a physical illness or injury, it’s usually easy to recognise when they need a bit of extra support. Mental health challenges, however, can be much less visible. Although attitudes to mental health problems have undoubtedly improved over the last decade or so, stigma still exists. Many people may struggle in silence, flying under the radar until they’ve reached crisis point.

However, poor mental health is much more common than you’d think; in fact, according to the Health and Safety Executive (HSE), an estimated 964,000 workers in the UK have experienced work-related stress, depression or anxiety in recent years. That’s why it’s important for businesses to create a workplace where mental health challenges are recognised and understood, which is where mental health first aid can make a real difference.

But what is mental health first aid and how can it benefit both employers and employees? The team at Healthier Workforce has written this guide to help you understand why it matters in the workplace.

What is mental health first aid?

If you cut yourself or faint, you’ll usually receive first aid to help patch you up and prevent your illness or injury from getting worse. Mental health first aid (MHFA) operates on the same principle, but instead of treating physical ailments, it addresses the signs of poor mental health. Essentially, it involves understanding the signs of common mental health problems, learning how to support someone who may be struggling and knowing which support services they should be guided towards.

Mental health first aid is an initiative that was started in Australia in 2000. Originally launched as a one-day training course covering the early warning signs of mental health issues, the programme soon snowballed. Subsequently, mental health first aid was introduced to the UK in 2007 as part of a Department of Health campaign.

Why is mental health first aid so important?

It prevents escalation: Mental health issues rarely develop overnight; people often struggle in silence for weeks before things hit boiling point. Mental health first aid ensures early intervention by making sure others can spot the first signs of poor mental health before they escalate.
It reduces stigma: Even now, mental health is still a bit of a taboo subject, and some people may avoid seeking help for fear of judgement. Mental health first aid encourages openness and normalises conversations about emotional wellbeing, meaning people might feel safer about opening up.
It builds confidence: If an employee has concerns that one of their colleagues is struggling, they might ignore the problem, worried that they’ll accidentally say the wrong thing and make the whole situation worse. Mental health first aid training helps to give employees the confidence to approach colleagues, start conversations and offer appropriate support.
It reduces staff absences: According to data from the HSE, there are roughly 22.1 million sick days across the UK each year that are linked to poor mental health. However, by helping employees access support at an earlier stage, mental health first aid can help to reduce the risk of mental health concerns escalating into long-term sickness. This is supported by research too, as organisations with a mental health first aid programme in place have reported a 59% increase in employees seeking professional help before they suffer complete burnout.

What is a mental health first aider?

A mental health first aider (MHFAider) is someone who has completed an accredited MHFA training course and is equipped to recognise the signs of a range of common health issues. They act as an initial point of contact for those experiencing poor mental health and are there to listen without judgement and signpost the person towards professional support.

What does a mental health first aider do?

In the same way that a physical first aider provides immediate support after an injury or illness, a mental health first aider is there to act as a point of contact for colleagues who may need a bit of support with their mental health.

Their responsibilities include:

Looking for the early warning signs that a colleague is experiencing burnout or mental health issues
Initiating conversations with those who may be struggling
Offering a safe, non-judgemental space where employees can share their concerns
Maintaining confidentiality at all times unless someone’s life is in danger
Providing immediate crisis support in difficult situations, such as panic attacks or severe depressive episodes
Assessing the risk of harm
Understanding when it’s necessary to contact the emergency services
Signposting people towards additional support, such as their GP, NHS talking therapies or an occupational health specialist
Promoting mental health awareness in the workplace and helping to reduce stigma

Being a mental health first aider can also be challenging and emotionally draining at times, so it’s important to be able to set healthy boundaries, recognise your limits and protect your own wellbeing.

What does a mental health first aider NOT do?

As well as celebrating the great work that mental health first aiders do, it’s important to recognise their limitations too. While mental health first aiders are able to provide initial support to colleagues going through a mental health crisis, they aren’t medically trained and should never be used as a replacement for doctors, therapists or other mental health professionals.

A mental health first aider shouldn’t overstep their role and will never be responsible for:

Diagnosing a mental health condition
Making clinical assessments
Providing therapy or counselling
Prescribing medication
Offering unsolicited advice – their role is to support and listen
Forcing help on anyone
Referring anyone to HR
Functioning as an ongoing support system – their job is to provide initial, short-term support

Who can become a mental health first aider?

Almost anyone can be a mental health first aider at work, provided they’ve undergone the proper training. Unlike other roles, which might require qualifications or experience, being a mental health first aider should be accessible for everyone, provided you have a genuine interest in supporting the wellbeing of your colleagues.

Ideally, a business should have a range of mental health first aiders across different departments and levels of seniority. This makes it more likely that every employee will be able to find someone that they know and feel comfortable talking with, as opposed to relying on a couple of individuals who may not be familiar with everyone.

It’s important that mental health first aiders feel comfortable having open conversations about mental health; if you’re someone who finds it difficult to discuss sensitive topics or you might get upset hearing about someone else’s mental health struggles, then this role may not be for you.

The ideal mental health first aider should be:

A good listener: able to give someone their full attention without feeling dismissed
Non-judgemental: they should be open-minded and able to put aside their own opinions and assumptions
Approachable: someone who colleagues feel they can come to in a time of crisis
Empathetic: able to understand that everyone’s experiences with mental health are different
Respectful: they should always maintain an appropriate boundary and should respect everyone’s privacy, never sharing anything they’re told in confidence
Patient: able to take their time, avoid rushing conversations and understanding that some people may need a little longer to open up

How can mental health first aiders work with occupational health?

If you’re a mental health first aider who has concerns regarding a colleague, encouraging them to visit an occupational health specialist can make a real difference.

While your role is to provide initial support and signpost them to the right services, an occupational health practitioner is trained to carry out an in-depth assessment of how an employee’s physical or mental health might be affecting their ability to work.

They can also provide lifestyle assessments to identify other factors that may be having an impact on your mental health, such as lack of sleep, poor nutrition and alcohol consumption.

Additionally, occupational health specialists and mental health first aiders can work together to promote workplace health and wellbeing initiatives, helping to create a culture where employees feel fully supported and comfortable asking for help.
