UK Budget Introduces PDEL to Ringfence Preventive Public Spending
A new fiscal mechanism aims to protect long-term preventive investments from short-term budget cuts.
1The Birth of PDEL
John Healey’s October budget introduced the Preventative Departmental Expenditure Limit, known as PDEL. This new fiscal category aims to protect funding for preventive policies, such as tackling rough sleeping. While not a blockbuster measure, it represents a significant shift in how the Treasury categorizes and manages public spending priorities moving forward.
2Challenging Treasury Norms
The Treasury typically forces departments to cut budgets during spending reviews to show immediate savings. However, this approach often ignores long-term costs across different sectors. PDEL challenges this by arguing that upfront investment in areas like family hubs can generate substantial savings for welfare, health, and criminal justice systems years later.
3Evidence from Demos
A 2023 paper by the thinktank Demos identified 22 billion pounds in government costs that could have been averted through preventive programming. The organization argues that for decades, the system has prioritized crisis management over prevention. PDEL is designed to change this narrative by creating a dedicated storyline for preventive resource spending.
4Historical Fiscal Precedents
The separation of spending categories has historically influenced policy debates. Before 1997, investment and day-to-day spending were not formally distinguished. Gordon Brown later separated RDEL and CDEL to implement the golden rule, allowing borrowing for investment. PDEL follows this logic, aiming to bring scrutiny to spending areas that provide long-term social value.
5Data-Driven Policy Shifts
Gavin Kelly of the Nuffield Foundation notes that improved data capabilities now allow for forensic linking of datasets across public services. Studies on Sure Start centers demonstrate how early interventions boost education performance and reduce hospital admissions. Policymakers can now better quantify the long-term impact of decisions made in one specific department.
6Defining Preventive Projects
The Treasury has not yet provided full details on how PDEL will be defined, but departments must justify individual projects as preventive. Potential areas include rough sleeping, early mental health support, and obesity prevention. Alan Milburn is also expected to advocate for employment support for youth using this preventive logic to save future costs.
7Potential Fiscal Evolution
There is speculation that if defined strictly enough, preventive spending could eventually be classified as investment for fiscal rule purposes. This would allow the government to borrow today to fund projects that save money over time. While the Treasury currently denies this is the plan, the logic mirrors traditional infrastructure investment strategies.
8Future Spending Constraints
Despite the introduction of PDEL, the upcoming spending review remains difficult, with the Institute for Fiscal Studies estimating 27 billion pounds in spending pressures. PDEL may struggle to play a starring role against such a bleak narrative. Ultimately, its success depends on whether it can foster genuine long-term thinking within the Treasury.
