When the London Health Commission reported in 2014, it set out a stark assessment of health inequalities across the capital and a programme of reform under the banner Better Health for London. The Mayor’s response, published shortly afterwards, accepted the central diagnosis: where a Londoner lives still shapes how long they live and how many of those years are spent in good health. A decade on, the inequalities of health the Commission described remain the defining challenge for public health in London, and the response continues to frame how boroughs, the NHS in London and City Hall set their priorities.
What the Mayor’s response committed to
The response did not treat the Commission’s findings as a single event but as a standing agenda. It endorsed the ambition to make London the healthiest major global city, and it organised the reply around the Commission’s own themes: giving every child a healthy start, helping Londoners stay healthy, providing the best care when people are ill, and creating a city designed for health. Crucially, it accepted that health inequalities could not be closed by the health service alone — housing, air quality, employment, transport and the food environment all shape outcomes long before anyone reaches a GP surgery or a hospital.
Why health inequalities in London are so wide
The Commission’s evidence showed a gap of several years in life expectancy between the most and least deprived London boroughs, and an even wider gap in healthy life expectancy. Those differences are not random. They track deprivation, ethnicity, and the conditions in which people are born, grow, work and age. The inequalities of health visible on a tube map — where life expectancy can fall by roughly a year for each stop travelled east from central London — are a consequence of these wider determinants, not simply of differences in clinical care.
From diagnosis to prevention
The most durable part of the response was its emphasis on prevention. Tackling smoking, obesity, physical inactivity and harmful drinking — the behavioural drivers behind most premature deaths — promised more years of healthy life than any single hospital programme. Prevention also depends on early detection: catching high blood pressure, diabetes, and cardiovascular risk before they become emergencies. That is where structured screening and accessible community diagnostics matter, because they convert good intentions into measurable, earlier intervention.
The role of screening and diagnostics
A health system serious about narrowing inequalities has to bring testing closer to the people least likely to seek it. Community diagnostic capacity — blood-pressure checks, blood glucose and cholesterol testing, spirometry, and basic point-of-care assessment — allows risk to be identified in the settings people already use. Reliable, well-maintained diagnostic equipment is the practical backbone of that work: without dependable devices in clinics, pharmacies and outreach settings, the policy ambition of earlier detection stays on paper.
What changed, and what didn’t
- Smoking rates in London have fallen, broadly in line with the Commission’s ambitions, though they remain higher in deprived communities.
- Childhood obesity remains stubbornly high in many boroughs, with a clear social gradient.
- Air quality has improved in central zones but continues to drive respiratory ill-health across the city.
- Access to care is more uneven than the Commission hoped, with primary-care pressure concentrated where need is greatest.
The honest verdict is mixed. London has moved in the right direction on several indicators, but the underlying inequalities of health the Commission identified have not closed.
FAQ
What was the London Health Commission?
An independent inquiry, commissioned by the Mayor of London, that reviewed the city’s health and care and published the Better Health for London report in 2014 with recommendations to improve health and reduce inequalities.
What did the Mayor’s response say?
It broadly accepted the Commission’s diagnosis and ambitions, committing to action across prevention, children’s health, care quality and the wider determinants of health.
Are health inequalities in London still a problem?
Yes. Significant gaps in life expectancy and healthy life expectancy persist between London’s most and least deprived communities.
