The UK's chip policy has entered a phase that is more honest than its predecessors: the Department for Business and Trade's Export Control Joint Unit (ECJU) has continued tightening the UK Strategic Export Control Lists through 2025-2026, and the Cabinet Office is leaning more heavily on the National Security and Investment Act 2021 to screen chip-related foreign investment. Together, the two regimes now form a coherent — if uncomfortably reactive — instrument for aligning Britain with the US Bureau of Industry and Security (BIS) and Dutch export rules on advanced lithography and AI accelerators bound for China.
This convergence is no longer subtle. Since the United States issued its sweeping October 2022 controls on advanced computing items and subsequent updates, and the Netherlands restricted ASML's most advanced deep ultraviolet (DUV) lithography tools, Britain has steadily added matching entries to its dual-use lists. The ECJU's licensing footprint now extends across high-performance compute, EDA software, advanced packaging materials, and a widening set of design services — categories that barely featured in UK controls a decade ago.
From Nexperia to a Genuine Investment Screen
The political turning point was the 2022 order requiring Chinese-owned Nexperia to divest most of its stake in Newport Wafer Fab (now Vishay Newport), issued under the NSI Act. That decision, announced by then-Business Secretary Grant Shapps, set the precedent that compound semiconductor capacity — even at trailing-edge nodes — could constitute a national security asset. The Cabinet Office's NSI Annual Report 2023-24 showed the regime maturing: hundreds of mandatory notifications in semiconductors, advanced materials, AI and quantum, with a small but rising share called in for full national security assessment.
The substantive shift in 2025-2026 has been quieter. Rather than blocking deals outright, the government has increasingly attached behavioural undertakings — board observation rights, technology-transfer firewalls, customer-screening obligations — to clear acquisitions. This is closer to the United States' CFIUS practice and is, on the whole, the right direction: a scalpel rather than a sledgehammer.
The Strategy That Hasn't Quite Caught Up
The problem is that Britain's National Semiconductor Strategy, published in May 2023, committed up to £1 billion over a decade — a figure that looked modest then and looks anaemic now. The United States CHIPS and Science Act mobilised roughly $52 billion in subsidies. The European Chips Act targets €43 billion in public and private investment. Even modest, focused British strengths — compound semiconductors in South Wales, IP design at Arm, photonics in Glasgow and Southampton — are competing for global capital against jurisdictions willing to write much larger cheques.
Layering export controls and investment screens on top of a thin industrial base creates a structural risk: Britain becomes a node that is harder to invest in but no easier to build in. The Pisces think tank and the House of Commons Business and Trade Committee have both flagged this asymmetry. The Committee's 2024 report on semiconductors warned that licensing delays — sometimes stretching past the ECJU's 20-working-day target — were already pushing customers to source from less-restricted jurisdictions.
Where Controls Make Sense — and Where They Drift
There is a sound, narrow case for the current restrictions. Advanced AI accelerators and EUV lithography are genuine dual-use chokepoints with plausible military relevance. Coordinating with allies who control the upstream equipment market — chiefly the Netherlands (ASML), Japan (Tokyo Electron), and the United States (Applied Materials, Lam, KLA) — increases the controls' effectiveness while reducing unilateral commercial damage to UK firms.
But the drift is real. ECJU guidance now covers categories where the dual-use logic is weak:
- Mature-node chips used in consumer electronics and automotive, where a Chinese end-user is not meaningfully different from a Vietnamese or Mexican one.
- General-purpose EDA and academic research collaborations, where over-broad interpretations have reportedly chilled university partnerships.
- Cloud-delivered compute, where the line between "exporting a chip" and "providing a service" is increasingly arbitrary.
Each over-extension imposes compliance costs on UK startups, academic labs, and SMEs that lack in-house export-control teams. The Royal Academy of Engineering and techUK have repeatedly urged the government to publish clearer, narrower technical thresholds rather than relying on case-by-case licensing.
The Geopolitical Backdrop
The May 2026 Trump-Xi meeting in Beijing, where AI chip access, rare earths, and Nvidia's China business are reportedly on the agenda (per Rest of World's 13 May reporting), illustrates how fluid the underlying regime is. The Trump administration's January decision to permit Nvidia's H200 sales to China in exchange for a 25% government cut — and Beijing's reported objections — show that the US position is itself unstable. If Washington blinks, Britain will be left enforcing controls more aggressively than the country whose policy framework it has been mirroring.
What a Proportionate UK Regime Looks Like
A pro-innovation, proportionate approach would do four things:
- Publish bright-line technical thresholds (process nodes, FLOPS, interconnect bandwidth) rather than discretionary "catch-all" clauses, so firms can self-assess.
- Statutory ECJU service-level targets with public reporting on licence turnaround — slow licensing is a tax on UK exporters that competitors do not pay.
- Carve-outs for academic research and open-source EDA tooling, with narrow exceptions only for items genuinely tied to advanced military end-use.
- Match the screen with capital: an NSI regime without a credible UK CHIPS Act is a defensive crouch, not a strategy.
Britain has the legal architecture in place. What it still lacks is the industrial confidence — and the budget — to make these controls feel less like a moat around a shrinking castle and more like a fence around a growing one.
