Ten years on, Brexit’s economic impact is becoming clearer

Ten years on Brexit s economic – As the UK navigates its post-Brexit era, the long-term effects of leaving the European Union are starting to surface. A decade after the decision to depart, new data is shedding light on how trade and economic activity have shifted. One illustrative example comes from Bristol-based Eskimo, a company that once thrived on exporting energy-efficient radiators across Europe. In 2020, the firm’s exports to the EU accounted for nearly half its business, but by 2025, that figure had plummeted to just 5%. This decline highlights the challenges faced by businesses in the UK as they adapt to new trade arrangements and regulatory hurdles.

The Struggle of a Small Business

Eskimo’s story is emblematic of a broader pattern. The company’s innovative electric radiators, designed with cutting-edge technology, were initially poised to capitalize on Europe’s green energy goals. However, the post-Brexit trade deal negotiated under then-Prime Minister Boris Johnson in December 2020, while eliminating tariffs on goods sent to the EU, introduced new complexities. Phil Ward, the firm’s founder, explains how administrative barriers—such as paperwork not tied to tariffs—created delays and added costs, deterring potential customers.

“The Long Brexit effect has been a drag on growth. In 2020, 40% of our exports went to the EU, but by 2025 it was just 5%,” Ward says. “Even with zero tariffs, the red tape and uncertainty have made it harder to compete.”

These challenges were not limited to the UK’s immediate neighbors. Eskimo’s attempts to expand into Germany faltered, and exports to Australia and New Zealand, though less affected by the EU’s rules, still faced obstacles. Both countries rely heavily on the EU’s CE mark to ensure product safety standards, meaning UK firms had to navigate an unfamiliar regulatory landscape. This situation, Ward argues, undermines one of the supposed advantages of Brexit: the ability for UK regulators to diverge from EU standards and foster innovation more freely.

Trade Variety and Economic Metrics

According to the UK Trade Policy Observatory at Sussex University, the number of different products traded between the UK and the EU dropped by 26% by 2023. A more recent study from Aston University Business School, using five years of detailed trade data, revealed an even sharper decline: 53.8% in the type of exports and 31.5% in imports. These figures reflect a reduction in trade variety, meaning fewer products are being sent to different EU countries. Such a decline could signal a loss of market access or a shift in production strategies.

While these statistics paint a concerning picture, their interpretation remains contentious. Some economists argue that Brexit’s impact has been underestimated, while others believe the data accounts for the disruption caused by global events. The period since 2020 has been marked by seismic changes, including the pandemic, the war in Ukraine, and the energy crisis sparked by conflicts in the Middle East. These factors have made it difficult to isolate Brexit’s effects from other external shocks.

The Debate Among Economists

Before Brexit, many experts predicted that the UK’s departure from the EU would lead to long-term economic damage. This prediction has now gained traction, as the data suggests a sustained decline in trade volumes. Yet, the analysis of Brexit’s impact hinges on comparing actual outcomes with hypothetical scenarios. The question is not just what happened, but what might have happened otherwise.

Nick Bloom, a British professor at Stanford University and author of a major study using Bank of England data, acknowledges the complexity of the issue. “Among economists, there’s little debate. The evidence shows that Brexit has had a measurable effect, though it’s taken time to materialize,” he notes. Bloom’s work, along with dozens of other academic papers, has contributed to a growing body of research on the topic. However, the methodologies used vary, and some critics question whether the data fully captures the true extent of Brexit’s impact.

One of the most significant arguments against Brexit’s economic benefits is the loss of trade varieties. Before 2016, UK-EU trade was on an upward trajectory, but this trend reversed after the departure. By 2025, exports to the EU had fallen by 14% compared to 2019 levels, while imports dropped by 10%. The most recent year, 2025, marked the worst performance for UK goods exports to the EU in over a century, excluding the financial crisis.

Global Context and Uncertainty

Analysts emphasize that Brexit’s economic consequences cannot be viewed in isolation. The global turmoil of the past decade has created an environment where traditional trade patterns have been disrupted. The pandemic, which began in 2020, caused supply chain disruptions and a shift in consumer demand. The war in Ukraine, which erupted two years later, further strained energy markets and trade routes. Meanwhile, the energy price shock linked to the conflict in the Middle East has added to the financial strain on businesses.

Some economists argue that these global factors have amplified the challenges of Brexit. For instance, the UK’s ability to keep pace with the tech boom in Silicon Valley has been questioned. If the EU had remained a single market, would UK firms have been as competitive? This uncertainty has led to a divide between academic researchers and policymakers, with the former generally supporting the data-driven conclusions and the latter expressing skepticism about the long-term implications.

Despite the challenges, there is a consensus that Brexit has had a lasting impact on the UK economy. While the initial economic hit was not as severe as some feared, the cumulative effect has been more pronounced. The reduction in trade varieties, the slower growth in exports, and the increased administrative burden all point to a deeper structural change. However, the debate continues over whether these effects are the result of Brexit alone or a combination of factors that have shaped the global economy in the past decade.

As the UK moves forward, the full implications of Brexit will likely take years to fully understand. The story of Eskimo serves as a reminder of the complexities faced by businesses in this new era. While the path to economic recovery is uncertain, the data provides a clearer picture of the challenges that have emerged since the UK’s departure from the EU. For now, the focus remains on how to navigate these obstacles and whether the UK can reclaim its position as a global trade leader in the years to come.
