The 2014 report Better Health for London is best known for its recommendations — smoke-free public squares, traffic-light labelling on restaurant menus, faster action on air quality. Less discussed is how the London Health Commission arrived at those conclusions in the first place. Before a single recommendation was drafted, the inquiry spent a year building an evidence base that combined public consultation, formal hearings, and quantitative health data. Understanding that process is essential to understanding why the report carried the weight it did.
A Mayoral Commission With a Specific Mandate
The London Health Commission was established by the Mayor of London in September 2013, with Lord Professor Ara Darzi appointed to chair it. Its brief was broad but pointed: assess the state of health and healthcare across the capital and set out a vision for London to become the healthiest major global city. That framing mattered. Rather than producing a narrow technical review of NHS services, the Commission was asked to look at health in the round — prevention, primary and community care, mental health, and the social conditions (housing, employment, air quality) that shape how healthy Londoners actually are. A panel of experts worked under Lord Darzi’s leadership to steer that wider inquiry, which is one reason the resulting report reads more like a strategic vision document than a conventional NHS review.
Building the Evidence Base Before Writing a Word
What distinguishes Better Health for London from many policy reports is the scale of engagement that preceded it. The Commission did not simply commission a literature review and write conclusions. Over roughly a year, it ran a deliberately wide evidence-gathering exercise designed to surface both public opinion and clinical and analytical evidence.
- Public consultation: the Commission gathered the views of more than 9,000 people across London.
- Borough-level events: over 50 roadshows and NHS-based events were held, with at least one in every London borough — a deliberate choice to avoid a central-London-only conversation.
- Written evidence: around 250 written submissions were received from organisations and individuals.
- Oral hearings: nine formal oral hearing sessions were conducted, allowing expert witnesses to be questioned directly.
- International benchmarking: London’s health performance was compared against other major global cities, to test whether the capital was actually falling short of what a wealthy world city could achieve.
- Quantitative analysis: the Commission applied cluster analysis to segment London’s patient population by need, giving the report a data-driven foundation rather than relying on anecdote alone.
- Public polling: polling was used to check whether the public actually recognised the importance of the issues being raised, and whether they would support the kind of action the Commission was contemplating.
Taken together, this was less a consultation exercise in the conventional sense and more an attempt to triangulate three different kinds of evidence — lived experience, expert testimony, and population-level data — before committing to a set of recommendations.
Three Ambitions Behind Sixty Recommendations
The resulting report set out a wide framework of ambitions for London’s health, with three themes doing much of the work of holding the document together:
| Theme | What it addressed |
|---|---|
| A healthy, happy start to life | Ensuring London’s children grow up healthy, with implications for adult physical and mental health later in life |
| A fitter London | Diet, exercise, and the everyday conditions — food environment, active travel — that shape weight and fitness across the population |
| Caring for the most mentally ill | Reducing inequalities in mental health outcomes so people with the most serious conditions live longer, healthier lives |
These three themes sat within a wider set of ambitions spanning the full report, which in turn translated into more than 60 individual recommendations — everything from planning restrictions on junk food outlets near schools to proposals for a dedicated London Health Commissioner tasked with driving the agenda forward on the Mayor’s behalf. The breadth was deliberate: the Commission’s evidence had shown that no single lever — not diet alone, not air quality alone, not mental health services alone — would materially shift London’s health outcomes on its own.
Why the Inquiry Process Still Matters a Decade On
Reports age. Recommendations get implemented, superseded, or quietly dropped. What tends to hold up better is the underlying method — and on that count, the 2014 inquiry set a standard that is still worth examining. A commission that combined borough-by-borough public consultation with formal evidence hearings and population-level data analysis was making a specific argument: that health policy for a city as large and unequal as London cannot be written from a desk. It has to be tested against what residents in every part of the capital actually experience, and against what the data says is really driving poor outcomes.
For anyone trying to understand what “Better Health for London” actually was — as opposed to a headline about smoke-free squares — the inquiry process is the part of the story that explains why the report carried authority when it was published. It was not simply Lord Darzi’s judgement. It was that judgement, tested against evidence from thousands of Londoners, dozens of boroughs, and a genuine attempt to compare the capital honestly against its global peers.
