References & Evidence

These are the sources that inform our programmes and the NE:U Business Savings Calculator (including the default 4.7× ROI). All links open in a new tab. Sources compiled from NE:U’s reference pack.

Core evidence (employer impact & ROI)

• Deloitte (2024) — Poor mental health costs UK employers £51bn a year.

• Deloitte (2022) — Mental health and employers: the case for investment.

• ROI benchmark — around £4.70 back per £1 invested (industry synthesis). See Deloitte’s 2024 discussion: The case for employers to invest…

• UK Labour Market denominators — House of Commons Library (2025): Labour Market Statistics.

How we use these in the calculator

Estimated Saving = ROI × Total Cost. We default to 4.7× (you can adjust). Employer cost and labour-market data frame the per-employee context for planning, not guarantees.

Pricing benchmarks (context)

• EAP pricing (examples): Health Assured • Service cost to employers • Spill.

• Wellbeing apps/packages: Stribe • Wellspace • Spark Your Health.

How we use these

These sources provide market context when comparing support options. NE:U focuses on training, culture and practical tools; any external pricing helps stakeholders calibrate value-for-money.

Measurement framework

• Warwick Medical School — WEMWBS (Warwick–Edinburgh Mental Wellbeing Scale).

How we use WEMWBS

We run baseline and review waves for teams to show trends and early-warning signals. WEMWBS is a population wellbeing scale (not diagnostic) and works well for programme evaluation.
