Brexit's Impact on UK Trade Becomes Evident
As the United Kingdom marks a decade since the Brexit referendum and six years outside the European Union's economic structures, the economic consequences are increasingly visible. While the 2020 post-Brexit trade agreement with the EU aimed for zero tariffs on exports, businesses have encountered other hurdles.
For instance, Eskimo, a Bristol-based manufacturer of electric radiators, saw its exports to the EU plummet from 40% in 2020 to just 5% by 2025. Despite tariff-free access, the company's founder, Phil Ward, cites administrative complexities and paperwork as significant deterrents, leading to delays and increased costs for European customers. This experience mirrors broader trends, with studies from the UK Trade Policy Observatory and Aston University Business School indicating substantial reductions in the variety of UK exports and imports with the EU.
Analyzing the Broader Economic Shifts
Many economists initially predicted long-term economic damage from Brexit, and numerous analyses suggest these predictions have materialized. However, assessing Brexit's precise impact requires distinguishing it from other global events such as the COVID-19 pandemic, the war in Ukraine, and subsequent energy price shocks. Economists generally agree that these external factors have been accounted for in their calculations.
Official figures reveal a downturn in UK-EU goods trade. Compared to 2019, UK exports to the EU in 2025 were down 14%, and imports were down 10%. Think tanks like NIESR and the Centre for European Reform have calculated similar shortfalls, with exports estimated to be 16-17% lower and imports 14-16% less than what would have been expected based on pre-2016 trends.
Services Sector Offers a Brighter Spot
In contrast to goods trade, the UK's services sector, which constitutes over 80% of its economic output, has shown stronger performance. Services exports from the UK to the EU have risen by 57% over the last decade, with significant growth in areas like accountancy, legal services, and consultancy. Exports to non-EU countries also saw a 49% increase. While some argue that this boom might have been even greater without Brexit, the financial services sector has demonstrated more resilience than some initial projections.
Investment and Currency Fluctuations
Business investment has also been notably affected. Studies by former Bank of England economist Jonathan Haskel and institutions like the National Institute of Economic and Social Research indicate a significant shortfall in business investment compared to pre-referendum trends, estimated to be around 12-13% lower. This decline is largely attributed to uncertainty in the years immediately following Brexit.
The value of the pound experienced a sharp decline immediately after the referendum and has generally traded lower against major currencies since then, although it has strengthened somewhat recently. A weaker pound makes imports more expensive but can also aid exporters by making UK goods cheaper internationally.
New Trade Deals and Their Limitations
One anticipated benefit of Brexit was the UK's ability to forge independent trade agreements. While deals with countries like India have been highlighted, government calculations suggest these agreements will only marginally boost economic growth over decades. Furthermore, while the UK secured an initial agreement to alleviate US tariffs, the EU has since gained similar benefits, sometimes with more favorable terms regarding quotas.
The Overall Economic Picture
The Channel Tunnel, a key artery for UK-EU trade, illustrates the impact. The number of trucks passing through annually has fallen by nearly 30% since 2016. Data from the LSE also indicates that 14% of UK firms that previously exported to the EU ceased doing so between 2019 and 2023, with smaller firms being disproportionately affected. This aligns with the academic consensus that the UK economy is now smaller than it would have been on its pre-2016 trajectory, with estimates ranging from a 3% to 8% reduction. Economists suggest that roughly half of this impact stems from increased trade friction with the EU, while the other half is attributed to the uncertainty generated by the Brexit process itself.
