How AI Could Revive Britain’s Economy — From Two Weeks to Two Hours

London, Nov. 24, 2025 — Artificial intelligence is raising fresh hopes that Britain could finally overcome its long-running productivity slump. In one striking example, accountants at a mid-tier UK firm slashed the time it takes to produce corporate fraud reports from two weeks down to just two hours — all thanks to AI.

The dramatic efficiency gains are coming at a critical moment: Britain’s services sector — which makes up about 80% of the economy — could benefit disproportionately from AI, particularly in finance, law, accounting, education and architecture. As firms ramp up AI adoption, economists say the surge could help unlock growth that has stalled for years.

However, the outlook is not without risks. While some executives celebrate the near-term productivity payoff, others warn that AI-driven gains may widen inequality between large, AI-enabled firms and those slower to adapt. Several companies also express concern that regulation isn’t keeping pace with technology — complicating long-term investment.

On the fiscal front, the government may not reap immediate benefits. Public finances remain stretched, and looming budget pressures could force tax increases even as AI begins to deliver on its promise. Meanwhile, top economists caution that job cuts could follow in certain industries, even as other sectors expand thanks to automation.

Still, the early signs suggest AI could play a transformative role in reshaping Britain’s economic future — if companies and policymakers can manage the trade-offs.
