Key facts
- UK welfare spending exceeded capital investment by £1.1 trillion over the last two decades.
- Welfare spending currently stands at 4.6% of total spending, while public investment is at 2.9%.
The UK spent over £1.1 trillion more on welfare programs than on capital investment in the past two decades, according to research. Welfare spending currently accounts for 4.6% of the total, while public investment represents 2.9%. The Office for Budget Responsibility (OBR) has been tasked with analyzing welfare spending trends and drivers since 2010.

The significant disparity between welfare spending and capital investment highlights a potential imbalance in government resource allocation, with implications for long-term economic growth and infrastructure development. The OBR's analysis of welfare spending trends and fraud rates provides crucial insights for fiscal policy and public finance management.

The Office for Budget Responsibility (OBR), established in 2010, has been tasked with providing independent analysis of the UK's public finances. Since 2013, it has also been responsible for assessing performance against a cap on a subset of welfare spending and publishing information on welfare spending trends and drivers. This is now a formal requirement under the Charter for Budget Responsibility, with a Welfare Trends Report (WTR) published every two years.
The OBR's 10th WTR, published in June 2026, focuses on the drivers of recent trends in welfare fraud and error. The rate of fraud and error rose sharply from 3.1% of spending in 2019-20 to 4.3% during the Covid years of 2020-21 and 2021-22, before falling back to 3.2% in the subsequent four years, close to its pre-pandemic level.
