The government’s 23 September 2026 update on Keep Britain Working is best read as an economic paper as much as a work-and-health review. Published by the Department for Work and Pensions, the Department for Business and Trade and the Department of Health and Social Care, it revisits Sir Charlie Mayfield’s independent work and argues that healthier, more inclusive workplaces should be treated as part of Britain’s growth toolkit rather than a niche HR concern.

That framing matters because the numbers are large enough to interest any finance director. GOV.UK puts health-related economic inactivity at around 2.8 million people and says the cost to Britain is roughly £212 billion a year, spanning lost output, health-related benefits, lost output from unpaid carers and added NHS costs. The same update says a 1% rise in participation would mean about 330,000 more people in work, while Health Foundation analysis cited in the paper points to a potential £57 billion uplift in annual output if working-age health returned to 2014 levels.

For employers, the report’s clearest point is that retention is cheaper than rescue. Around 300,000 people with a health condition leave work each year, and the intervention window closes quickly: someone absent for four to six weeks has a 96% chance of returning, but after a year fewer than half do, while the chance of moving back into work within a year falls to 3.8% once a person has become economically inactive for health reasons. That is why the review keeps coming back to earlier conversations, practical adjustments and better return-to-work planning rather than late-stage crisis management. (gov.uk)

The proposed answer is what the September paper calls Britain’s first Workplace Health System. In plain terms, that means three linked pieces: better and more inclusive workplaces, workplace health support that firms can actually use, and stronger intelligence on what is working. The British Standards Institution is already developing an employer-facing standard, with testing centred on clear but not overly rigid expectations, including work-and-health conversations within five working days of an issue being raised and a stronger focus on whether returns to work are still holding six months later.

This is where the business angle becomes practical, especially for smaller firms. The review accepts that many SMEs cannot build in-house occupational health teams, so it is testing pooled access, insurance routes and public provision such as WorkWell centres. Hull’s Resilience Hub is being used as a live example, giving local SMEs access to occupational health support at prices closer to those paid by large corporates, while South Yorkshire is preparing to trial shared case managers inside businesses for more complex cases.

Perhaps the most striking point for owners and investors is the paper’s frustration with weak measurement. The report says most employers can see absence data but very few track sustained return-to-work rates, and almost none can benchmark their retention of people with health conditions against peers. An employer data project due to start in autumn 2026 is meant to test whether firms can share comparable information confidentially, giving ministers, providers and employers a firmer basis for deciding what support deserves to be expanded.

There is still a long way to go. Ahead of the 2027 Spending Review, the next phase is about testing the model with Vanguard employers, local authorities and devolved administrations, then building the evidence needed for a wider roll-out. For Market Pulse UK readers, the message is fairly direct: if government is right, workplace health is moving out of the wellbeing brochure and into the operating model. That suggests firms that improve absence management, disability inclusion and line-manager capability early may end up with a measurable productivity edge as policy catches up. (gov.uk)
