The MHFA business case — the numbers HR teams quote to finance directors
MHAW 2026’s theme is Action. The question your CFO will ask, once the awareness week is over, is: “why this, why now, and what’s the return?” This guide gives you the answer.
964,000 UK workers reported work-related stress, depression or anxiety last year — up 24% year-on-year. Mental Health Awareness Week brings the pain point to the surface. A trained Mental Health First Aid team is what turns next week’s conversations into something measurable. HSE 2024/25

The rest of the guide covers the MHFA England ratios, the three numbers your CFO will ask for, the four mistakes HR teams make most, and a board-ready implementation timeline. One-off — you won’t need to do this again on this device.
Three numbers that make the case in under a minute
If you only have 60 seconds in the board meeting, this is the structure. The cost of doing nothing. The cost of the training. The return — grounded in what happens in your organisation, not a vendor’s brochure.
Annual cost of poor mental health to UK employers — absence, presenteeism and staff turnover combined. (Deloitte, Mental Health and Employers, most recent edition.)
UK workers affected by work-related stress, depression or anxiety in the last year. Up 24% year-on-year. Your people are in that number. (HSE 2024/25.)
Industry-reported ROI on proactive mental health training — Deloitte’s analysis puts the return at roughly £5 for every £1 spent. Ours tracks similarly.
Start with the MHFA England ratio your sector actually needs
MHFA England’s published workplace guidance sets out recommended ratios of trained first aiders to staff. Most HR teams quote one number; the real answer depends on your industry risk profile. Apply the right one and your board gets the credibility signal it needs.
- Lower-risk office environments: roughly 1:100 — one trained MHFA per 100 employees. Professional services, most financial services, most tech.
- Higher-risk or frontline environments: roughly 1:50 — construction, manufacturing, healthcare, emergency services, hospitality.
- Geographic spread matters more than headcount. A 200-person company on three sites needs first aiders on each site — headcount alone understates the requirement.
- Plan for attrition. MHFA certification lasts three years and staff leave — recruit roughly 20% above your target to stay at ratio.
Build the costed case your CFO will sign off
A CFO doesn’t sign off on “we should do something for mental health.” They sign off on a costed case with a return. Four line items carry most of the weight.
- Absence avoided. Use your own absence data: average days lost to mental health in the last 12 months × average loaded cost per day. If you don’t track that, start with the CIPD benchmark of ~8 days per employee per year and work from there.
- Attrition cost reduced. Replacing an employee is widely costed at 6–9 months of their salary. Even one mental health-related resignation prevented typically exceeds the cost of the whole cohort’s training.
- Presenteeism reduction. Presenteeism costs roughly 2× what absence does but is harder to measure. Reference it directly to show you’ve thought about the full picture.
- Legal and reputational risk. Employment tribunal claims for failure to make reasonable adjustments for mental health are rising. A trained first-aid function is a material part of your defence, not a tick-box.
If you only track one number, track the cost of one preventable mental health-related resignation vs. the cost of your MHFA cohort. On our client data this is almost always a favourable comparison in year one.
Make it concrete: what a trained MHFA can actually do
Boards sign off on specifics, not abstractions. Here are the four specific capabilities that show up on day one of a trained cohort — and that absolutely don’t exist the day before.
- Recognise. Spot the early signs of anxiety, depression, eating disorders, psychosis and suicidal ideation — in colleagues, before they escalate to crisis.
- Respond. Start a supportive conversation using ALGEE — the MHFA England intervention framework — without accidentally making the situation worse.
- Signpost. Know the difference between what MHFAs handle in-house and what must be escalated to a GP, A&E, Samaritans or your EAP — and act on that distinction in the moment.
- Maintain boundaries. MHFAs are not counsellors. The training is very clear on what they don’t do — which protects your people and reduces organisational risk.
The Mental Health Foundation has explicitly asked organisations this year to move beyond awareness into action. If your leadership is uncertain whether to commit, the campaign’s own message gives you the internal cover you need.
Four traps HR teams fall into when they make this case
Great cause, poor business case. We see these patterns in almost every internal proposal that gets rejected or delayed.
Leading with awareness, not numbers
“1 in 4 people experience mental health issues.” True, but generic — and every board has heard it. Lead with your organisation’s own absence, attrition and productivity data. Awareness is the hook; numbers are the sign-off.
Training one or two “champions” and calling it covered
Two first aiders in a 300-person organisation is worse than none — they burn out, you look like you’re ticking a box, and when one leaves you’re down to 0.5:300. Hit the ratio or don’t start.
Training the people, forgetting the policy
MHFAs need: protected time to respond, referral pathways written down, line-manager cover, and a regular peer-support rhythm. Train people into an unclear role and they quit it quietly.
What works instead
Train a cohort large enough to hit the ratio. Write the role — hours, boundaries, referral pathways — before day one. Book quarterly refreshers, not just the two-day course. Report outcomes upwards every six months. Treat it as a governance line, not a wellbeing initiative.
Over a third of UK workers say they don’t feel comfortable raising mental health concerns with their manager. A named, trained MHFA team is the most direct way to close that gap. Mental Health Foundation
From MHAW to a trained cohort in 90 days
If you start the conversation during this week, a trained cohort is live in your organisation before the end of Q3. Here’s the realistic shape.
Use MHAW to open the door
One all-hands or leadership session positioned as “the first step in a longer commitment.” Announce that a formal business case is being prepared. That commits you publicly and protects the initiative from being quietly deprioritised in June.
Draft the board case
Your absence and attrition data, MHFA England ratio, cohort cost, realistic ROI framing, governance structure. Get one board ally aligned before the formal paper goes up. Don’t overthink the document — one page plus a costed appendix is enough.
Get sign-off and select the cohort
Approval in the June board. Open expressions of interest internally. Select for diversity across teams and sites — not just volunteers from HR. Book the training.
Deliver the two-day accredited course
MHFA England accredited two-day course. Cohorts of up to 16 at a time. Onsite or online. Certified first aiders live from day three onwards.
Embed it as a governance item
Quarterly peer-support meet-ups, six-monthly reporting to the board, annual refresher training, three-yearly re-certification. This is the step that separates real impact from a one-off training spend.
Turn this week’s conversations into a trained cohort by summer
Our Mental Health First Aid course is MHFA England accredited. Two days, up to 16 people, onsite or online. We’ll help you size the cohort and shape the case before you commit.
