Deloitte's Famous Mental Health ROI Figure Is Older Than the Headlines Suggest

Deloitte UK says employers get back roughly £5 for every £1 spent on staff mental health, a line refreshed in November 2025 and still doing the rounds in 2026 coverage. This includes practices like yours, if you employ anyone besides yourself.

Whole-practice growth for wellness practices. Rooted in Wiltshire, UK, working worldwide.

Practices quoting this figure to corporate clients or funders should know it is a well-worn number given a fresh coat of paint, not a new finding.

OverviewDeloitte UK models the financial payback of employer mental health support using existing evidence, with the November 2025 edition updating a report line the firm has run for years.

PublisherIndustry body, Deloitte UK
Relevance to WellbeingWellbeing practices that employ staff, or that sell into corporate wellness budgets, can borrow this stat to make the financial case for mental health support, provided they date it honestly.
Our VerdictToo early to tell the underlying model is credible and widely cited, but the ratio has been recalculated and republished so often that "2026 research" is a stretch.
Our Summary
  • Deloitte's name lends the figure instant credibility with corporate clients and HR departments.
  • The direction of the finding (mental health support pays for itself) has held up across several editions of the report.
  • The exact multiplier drifts between reports (£5, £4.70, other figures in earlier editions), which suggests modelling assumptions rather than one clean survey result.
  • The 2026 framing obscures the fact that the analysis draws on older evidence rather than a fresh 2026 study.
Our Geo ViewFigures are UK-specific, built on UK sickness absence and NHS-adjacent costs, so treat the ratio as illustrative rather than transferable outside the UK.

Why this might matter to you

  • Coaching: this matters because corporate coaching pitches often lean on exactly this kind of return-on-investment line.
  • Therapy: this matters because employer-funded therapy schemes get approved on numbers like this, so knowing where they come from helps you sound sure of yourself.
  • Training: this matters because workplace training budgets get justified with ROI figures, and a shaky one undermines the whole pitch.
  • Alternative Healing: this matters because corporate wellness days are increasingly sold on cost-benefit logic, not just good vibes.
  • Clinical: this matters because occupational health referrals and EAP contracts are often won or lost on figures exactly like this one.
  • Retreat/Centre: this matters because corporate away-days get greenlit by finance departments who want a number, any number, to point at.

Where this came from

Deloitte UK's long-running attempt to put a price on mental health support paying off, refreshed again in late 2025 and still being quoted into 2026.

Deloitte UK, Mental Health and Employers report, November 2025 edition. Coverage citing the figure in 2026 largely repeats the same underlying model rather than presenting new fieldwork.

Credibility flags: economic modelling based on existing evidence rather than a single fresh survey, exact sample and methodology details not fully disclosed in press coverage, publisher is a professional services firm with a commercial interest in the topic.

How we scored this

A relevance score out of 100, built from three things: how well it fits the six practice types, how recent it is, and how solid the methodology behind it is.

40%
Practice fit, 50How new, 40How solid, 25

Marked up on practice fit for touching mental health and workplace wellbeing directly, marked down on recency since the modelling reaches back years, and marked down on how solid the method is given the figure's habit of shifting between editions.

It's worth considering changes to your marketing practices

What this means for your marketing

  • If you use the £5-for-£1 line, say "Deloitte's modelling" rather than "new 2026 research".
  • Brief your team on the fact that the exact figure varies between reports, so nobody gets caught out quoting £5 when a client has seen £4.70 elsewhere.
  • Put the source link on any proposal that cites the stat, so it looks checked rather than borrowed.
  • Pair the ROI line with your own practice's outcomes where you can, since a borrowed statistic works harder next to real evidence.
  • Say the date range up front before a prospective client asks how current the number is.

Best before

Best before: revisit when Deloitte next refreshes the report, and in the meantime check the primary Deloitte UK source before quoting a specific multiplier.

What next?

Every practice owner who has ever reached for a big shiny statistic to close a corporate pitch knows the discomfort of not being quite sure where it came from.
