No adopted mechanism to enforce the NHS 'prevention shift' in spending

The Hewitt Review (2023) recommended raising the share of ICS budgets spent on prevention by at least 1% over five years; the 10 Year Health Plan impact statement (January 2026) canvasses a prevention investment standard, Preventative Departmental Expenditure Limits and outcomes-based payment, but none has been adopted. There is no agreed definition or baseline measurement of NHS prevention spend. The ring-fenced local-authority public health grant exists, but NHS budgets have no equivalent instrument.

Every NHS strategy since 2006 has promised a prevention shift; without a measurable standard or Treasury category it stays rhetorical, because acute pressures always reclaim marginal funds. As the King's Fund put it: 'some is not a number, soon is not a time'.

A defined, audited prevention investment standard in NHS planning guidance with published ICB-level prevention-spend statistics, or an HM Treasury Preventative DEL created at the 2027 Spending Review. A fundable precursor: definitional and measurement work by ONS/DHSC analysts or an independent centre (Health Foundation REAL Centre).

// Build now: First artefact: independent prevention-spend definition and measurement (REAL Centre-style) from published/FOI-able ICB data; the Treasury DEL is state-led.

The prevention shift has been promised since 2006 but stays rhetorical without an agreed definition or Treasury category, and no live date this year forces adoption.
