Ten Years of Brexit: Five Signs of Rupture in UK Manufacturing

I. A Microcosm of the Automotive Industry: Nissan Sunderland’s Decade of Ups and Downs

Before the 2016 referendum, the Nissan Sunderland plant was seized upon by both camps as a symbol. The Remain camp saw it as a manufacturing benchmark under the dividends of the EU single market, while the Leave camp viewed it as proof of the UK’s independent trading capabilities. A decade later, the narrative of this symbol has been completely rewritten.

The plant’s output fell from 507,000 vehicles in 2016 to 273,000 in 2025, a near halving. Despite the government providing £162 million in subsidies and several secret commitments, it could not offset the non-tariff barriers and long-term uncertainty brought by Brexit. More noteworthy is that Nissan’s global troubles (leadership turmoil, 20,000 global job cuts) resonated with the UK’s Brexit, exposing the structural weakness of the British automotive industry: excessive dependence on foreign capital and a lack of resilience in domestic supply chains.

A recent contract manufacturing agreement with Chery has given the plant some breathing room, but the fact that it maintains existing jobs rather than creating new ones shows that the UK’s appeal as a car manufacturing base has degraded from “Gateway to Europe” to “Low-risk outsourcing node.” Behind this lies the persistent friction costs imposed on high-value-added industries by rules of origin and customs procedures under the UK-EU Trade and Cooperation Agreement.

II. Empty Promises for the Fishing Industry: How 0.3% of the Economy Hijacked Industrial Policy

Fishing accounts for only 0.3% of the UK economy, yet it occupied a central narrative in the Brexit debate. A decade later, fishers generally feel betrayed. EU fishing vessels can still operate in UK waters until 2038, while the UK distant-water fishing fleet has shrunk from multiple vessels to just the *Kirkella*.

The deeper problem is that Brexit has not changed the market structure for UK seafood. The value of UK seafood imports (£4.1 billion) is double that of exports (£2.0 billion), while domestic consumers have limited interest in key catches like lobster and crab, the vast majority of which still need to be exported to the EU. New non-tariff barriers such as phytosanitary inspections and certificates of origin, combined with stricter visa restrictions for migrant crew, have sharply increased industry costs.

The fishing case reveals a common dilemma: the “sovereignty dividend” promised by Brexit has been eroded by industrial logic and market structure in reality. When the UK tried to exchange “border control” for trade benefits, it overlooked the interdependence of global supply chains.

III. The Price of the Blue Passport: How Border Friction Erodes Trade in Services

As a hallmark achievement of Brexit, the practical experience of the blue passport has become a common pain point for UK citizens and businesses. UK citizens no longer enjoy fast-track entry into the EU. The EU’s new Entry/Exit System (EES) has caused queues of up to six hours at some airports. The upcoming ETIAS pre-authorization system will add an extra £17 per trip.But the deeper impact lies in the aviation and transport services sector. Companies like easyJet have been forced to set up new entities, recertify aircraft and crews, adding millions in annual compliance costs. The separation of UK-EU aviation safety certification systems has created "dual certification" friction in the parts supply chain. This is directly reflected in tourism data: bookings rebounded in Greece after it lifted visa requirements for British tourists, while Spain and Portugal saw declines due to EES congestion.

Notably, demand for Irish passports has surged by 2,500% compared to before the referendum, indicating that citizens are voting with their feet, using "second identities" to circumvent the mobility barriers caused by Brexit. The long-tail effects of these individual choices on the UK labor market and consumption patterns have not yet been fully incorporated into industrial policy assessments.

4. The Labor Crisis in the Care Sector: Structural Gaps After Immigration System Overhaul

The hostility towards EU immigration during the Brexit debate had direct consequences for the care sector. Before the referendum, nursing homes across the UK relied heavily on EU staff, but hiring has since plummeted. By 2022, care sector vacancies had soared from 78,000 to 132,000.

The government's response—opening up overseas care worker visas in 2022—led to a surge in "care visa" applications to 161,600 (as of the year ending November 2023). But this figure masks the problem: the new migrants come mainly from non-EU countries, are more mobile, and often target short-term work, failing to address long-term stability. At the same time, stricter immigration rules have also put pressure on labor-intensive industries such as fishing, hospitality, and agriculture.

5. Industrial Policy Lessons: The "Subsidy Race" and Competitiveness Deficit After Brexit

Looking back over the decade, the total subsidies paid by the UK government to compensate for Brexit losses have far exceeded expectations—Nissan alone received at least £162 million, and the overall subsidy for the automotive industry could reach billions. But this is essentially a form of "defensive subsidy," used for compensation rather than enhancing competitiveness. In contrast, the EU is promoting reindustrialization through systemic policies such as the Critical Raw Materials Act and the Net-Zero Industry Act, while the UK finds itself in a reactive mode, scrambling to retain individual investments.

The more fundamental issue is that Brexit has not delivered the promised reindustrialization. Manufacturing value added as a share of GDP remains stuck at around 10%, and the trade deficit continues to widen. Even in emerging fields like AI and clean energy, the commercialization capacity of the UK's innovation ecosystem is constrained by barriers to market access and talent mobility.

The UK's industrial system is undergoing a silent structural adjustment: transitioning from a "beneficiary of European integration" to a "responder in global fragmentation." Whether this adjustment can translate into long-term competitiveness depends on the industrial strategy's ability to move beyond the "subsidy compensation" logic and shift towards systematically rebuilding supply chain resilience, skills bases, and export-oriented capabilities.
