Britain's National Debt Hits 100% of Output as Interest Costs Top £100 Billion

Summary
Britain’s public debt has climbed to about 100% of national output, up from roughly a quarter in the late 1980s and about two-thirds after the 2008-09 crisis.
More than £100 billion a year now goes to servicing existing debt, making it the government’s third-largest spending item; in 2025-26, about six of every seven pounds of new borrowing went to interest payments.
That debt burden has coincided with broader state dependence: more than 24 million adults receive some form of welfare, including 13 million pensioners and 10 million working-age claimants.
The report argues Britain has run deficits far beyond Keynesian crisis borrowing, with postwar governments rarely posting surpluses, leaving fiscal rules and bond-market pressure central to political decision-making.
The wider implication is that reducing reliance on borrowing—not ignoring bond markets—would be necessary to restore fiscal room and reverse what the report describes as long-term economic decline.
