A recent analysis comparing public spending ratios from the fiscal year 2007/8 to 2022/3 reveals significant shifts, particularly in health spending, which increased from 6.5% to 8.4% of GDP, while education spending declined from 5.0% to 4.2%.

Concerns have been raised regarding the Chancellor's budget analysis, which lacks depth on the necessary increases in public spending, potentially pressuring Labour to make unrealistic tax pledges to gain electoral support.

To effectively 'end austerity' and restore public services to the levels seen during the last Labour government, spending would need to be approximately 3% higher than current projections.

In October 2024, the Chancellor announced a 1.8% increase in total government spending as a share of GDP compared to previous plans, aiming to maintain a stable public spending ratio over the forecast period.

However, merely comparing the total ratio of government spending to GDP can be misleading, as it includes interest payments on debt, which do not accurately reflect the provision of public services.

Despite the increase in health spending as a share of GDP, this has not translated into improved health service provision, as evidenced by rising waiting times since 2010 despite stable health spending ratios.

Other sectors, including public order and safety, as well as long-term care, have also experienced reductions in public spending as a percentage of GDP, indicating a decline in public provision.

Current government spending plans may fall short of meeting public service needs unless significant adjustments are made to both tax and spending policies.

Looking ahead, the public spending ratio is projected to remain similar to that of 2022/3 by the fiscal year 2029/30, which marks the last full year of the Conservative government.

To revert to the levels of public spending seen in 2007/8, total spending must increase by 3% by 2029/30, taking into account the needs in health, education, and social security.

Historical trends indicate notable shifts in spending, with defense spending significantly decreasing since 1955, while health spending has steadily increased as a share of GDP, largely due to an aging population.

Although obtaining historical data on public spending components is challenging, the Institute for Fiscal Studies (IFS) has provided substantial analysis on these trends.
