OBR Warns Triple Lock Will Spike UK Public Debt

The Office for Budget Responsibility warned that the United Kingdom's state pension triple lock will add billions to public spending over the coming decades, potentially leading to unsustainable national debt. The fiscal watchdog projects that state pension costs could rise from 5 percent of GDP to approximately 9 percent by 2075-2076 if current trends continue, which could push total UK debt to 300 percent of GDP.

By 2029-2030, the OBR estimates the triple lock will add roughly £15.5 billion to annual state pension spending, a figure that significantly exceeds the original estimate of £5.2 billion. While an aging population also contributes to these costs, the OBR identified the policy as a primary driver of spending pressure.

These warnings follow recent statements from Andy Burnham, who is expected to become the next Prime Minister. On July 3, Burnham indicated that the Labour manifesto commitment to retain the triple lock would remain in place.
