& Evidence

The sources that inform NEU's programmes and the Business Savings Calculator. All links open in a new tab. Compiled from NEU's reference pack.

Core evidence — employer impact & ROI
Sources underpinning the default 4.7× ROI figure and the £51bn cost estimate.
Deloitte (2024) — Poor mental health costs UK employers £51bn a year.
Deloitte (2022) — Mental health and employers: the case for investment.
ROI benchmark — approximately £4.70 back per £1 invested (industry synthesis). See Deloitte's 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× (adjustable). Employer cost and labour-market data frame the per-employee context for planning, not guarantees.

Pricing benchmarks
Market context for comparing support options and calibrating value-for-money.
EAP pricing examples: Health Assured · Service cost to employers · Spill.
Wellbeing apps & packages: Stribe · Wellspace · Spark Your Health.
NEU focuses on training, culture and practical tools. These sources provide market context — not a direct comparison, since NEU's approach differs significantly from EAPs and apps.
Measurement framework
The validated tools underpinning NEU's wellbeing measurement.
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.
