Chancellor Rachel Reeves has pledged to halt the flow of British technology companies and scientific talent abroad, warning that the long-standing pattern of “business exodus” must end as part of a wider initiative to revive Britain’s economic growth.
Addressing a major address to business leaders in London, Reeves said the government would invest £2.5 billion in artificial intelligence and quantum computing to strengthen Britain’s position as a global technology hub and ensure more homegrown innovation scales at home rather than outsourcing it to markets such as the United States.
The intervention reflects growing government and industry concerns about the UK’s failure to retain its most promising technology companies. As the UK continues to produce world-class start-ups and research companies, many are ultimately moving abroad in search of deeper capital markets, more favorable tax regimes and stronger institutional support.
Reeves, of the National Quantum Computing Center, said her economic strategy is designed to reverse that trend through what she called a “more strategic and active state” that combines targeted investments with regulatory stability and stronger international partnerships.
At the heart of this strategy is a significant commitment to next-generation technologies. Quantum computing, widely seen as the next frontier of computing power, is expected to drive advances in every sector from pharmaceuticals to finance, while AI is already reshaping productivity, automation and decision-making across the economy.
Reeves is expected to argue that Britain can achieve the fastest AI adoption rate in the G7, putting the country at the forefront of a technological transformation that could define global competitiveness in the coming decade. It will also highlight the potential of quantum technologies to create up to 100,000 jobs and outline the investment as both an economic and industrial strategy.
However, the Chancellor’s ambitions face an increasingly difficult macroeconomic backdrop. The escalation of conflict in the Middle East has already led to a sharp rise in oil and gas prices and raised fears of renewed inflationary pressures and a slowdown in growth – factors that could complicate government efforts to boost investment and innovation.
Reeves acknowledged the risks, noting that global energy security has become a key concern as disruptions to key supply routes, including the Strait of Hormuz, continue to reverberate across international markets. She confirmed that decisions on key North Sea oil projects, including Rosebank and Jackdaw, would be made “soon” but stopped short of committing to accelerated domestic production.
Instead, she pointed to a broader energy resilience strategy, including closer cooperation with European partners. Plans to deepen integration into EU energy markets are expected to be part of a broader post-Brexit reset aimed at cutting costs and improving supply stability.
This approach extends beyond energy into regulation. Reeves is expected to signal his willingness to bring the UK more closely into line with EU rules in select areas where it will support growth, jobs and investment. While aligning food and agricultural standards has already been proposed to reduce trade tensions, the speech is likely to open the door to similar moves in sectors such as chemicals, manufacturing and advanced industries.
The prospect of closer alignment has already drawn political criticism. Opposition figures argue the strategy could dilute the benefits of Brexit, with shadow chancellor Sir Mel Stride accusing the government of trying to “drag” the UK back into the EU framework rather than addressing domestic economic challenges.
But for business leaders, particularly in the technology sector, the question is less ideological and more structural. The UK’s ability to retain high-growth companies has long been constrained by gaps in top-up funding, pension fund participation and the perceived competitiveness of the London Stock Exchange compared to US markets.
Reeves’ intervention appears designed to address these concerns head-on, positioning the UK as not only a place to start a business but also to grow and globalize. By combining public investment, regulatory pragmatism and international collaboration, the government hopes to create an environment in which British innovation can remain anchored at home.
Whether this goal can be achieved depends not only on policy implementation, but also on the general economic climate. Given geopolitical instability, energy price volatility and shifting global capital flows, the race to retain and scale technology companies is becoming increasingly competitive.
For now, Reeves is making it clear that the UK intends to actively participate in this race and that allowing its most valuable companies to move abroad is no longer an acceptable outcome.
