Public support for the founding principles of the National Health Service (NHS) in the United Kingdom has declined over the past five years, a recent analysis reveals. The core tenets—that the NHS should be free to use, accessible to all, and funded through taxation—have seen decreasing endorsement across most age groups between 2021 and 2025.
Research conducted by The King’s Fund, a health policy thinktank, examined data from the British Social Attitudes survey focusing on five generational cohorts: Generation Z (born 1997–2012), millennials (1981–96), Generation X (1965–80), baby boomers (1946–64), and those born before World War II. The findings show a noticeable drop in agreement that the NHS should be universally available and free at the point of use.
Among older generations, the decline was particularly marked. For instance, the share of respondents born before the war who believe the NHS should be accessible to everyone fell from 87.1% in 2021 to 73.2% in 2025. Similarly, support among baby boomers decreased from 83.1% to 71.2% over the same period. While the belief in the NHS’s free provision also declined, it remained held by a strong majority—between 85% and 92% of respondents.
The study highlighted generational differences regarding funding the service through taxation. Support among Generation Z for tax-funded NHS care dropped by 11.2 percentage points, from 85.3% in 2021 to 74.1% in 2025, a larger decline than seen in older cohorts, where levels remained at or above 80%.
Experts suggest several factors may have contributed to these shifts in public opinion. Danielle Jefferies, a senior analyst at The King’s Fund, noted that while overall support remains robust nearly eight decades after the NHS’s establishment, it should not be taken for granted. She pointed to broader societal changes, including evolving attitudes towards migration, as potential influences on the decreasing certainty about the principle of universal access.
Jefferies also emphasized the economic context as particularly relevant to younger generations. Facing unprecedented financial challenges, Generation Z adults are reportedly less inclined to support increased tax burdens to sustain public services. “Analysis from the Institute for Fiscal Studies suggests that younger adults today are economically worse off than previous generations,” she said, underscoring economic hardship as a likely contributor to the observed generational divide.
The decline in support for the NHS’s founding principles comes at a time when healthcare spending absorbs an increasing share of public funds amid rising demand from an aging population. Simultaneously, government priorities are shifting towards investments in areas such as defense, social care, and services for children with special educational needs and disabilities (SEND). These competing demands could complicate future efforts by policymakers to justify expanding the NHS budget.
