UK-EU trade after Brexit operates under the Trade and Cooperation Agreement (TCA), which ensures zero tariffs and zero quotas on goods. However, non-tariff barriers continue to create friction for many businesses. Customs bureaucracy, SPS inspections, and regulatory divergence weigh heavily on British exporters. The mandatory five-year review of the TCA in 2026, alongside the Labour government’s reset agenda, offers an opportunity to smooth out these trading issues.

The Post-Brexit Trade Landscape
The United Kingdom formally left the European Union’s single market and customs union on 31 December 2020. The Trade and Cooperation Agreement (TCA) took effect provisionally in January 2021 before full entry into force in May 2021. This framework now governs all economic relations between both sides.
Five years later, UK-EU trade after Brexit presents a mixed picture. The agreement successfully prevents tariffs on physical goods, yet British companies face significant practical hurdles. Administrative burdens and new customs checks regularly slow down supply chains.
Following the May 2025 UK-EU Summit, the Labour government started pursuing an ambitious reset. The upcoming 2026 review offers a chance to renegotiate friction points and improve conditions for exporters.
What the TCA Framework Provides
The TCA covers several major areas, including energy, fisheries, transport, trade, and social security coordination. For physical goods, the primary rule is clear: zero tariffs and zero quotas apply as long as products meet rules-of-origin requirements.
Without this agreement, trade would have reverted to basic World Trade Organization rules, which would have triggered heavy tariffs. Therefore, the deal gave businesses vital stability.
+-----------------------------------------------------------------------+
| TCA Framework Overview |
+-----------------------------------+-----------------------------------+
| Covered Features | Omissions / Exclusions |
+-----------------------------------+-----------------------------------+
| • Zero tariffs on qualifying goods| • Comprehensive services framework|
| • Zero quotas on qualifying goods | • Financial services integration |
| • Energy & transport rules | • Mutual recognition of qualifications|
+-----------------------------------+-----------------------------------+
Despite these benefits, the TCA lacks a comprehensive structure for services. This omission severely affects the UK, as service sectors form the backbone of the economy. A Memorandum of Understanding on financial services signed in June 2023 improved regulatory cooperation, but it falls short of pre-Brexit market access.
The Office for Budget Responsibility estimates that UK GDP will ultimately sit 4% lower than it would have inside the EU, while total trade volume will drop by roughly 15%.
Key Statistics in UK-EU Trade After Brexit
The European Union remains the United Kingdom’s largest trading partner. Recent data from February 2026 shows UK exports to the EU reaching £15.2 billion (up 2.1% year-on-year), while EU imports reached £27.5 billion (up 4.9%). Consequently, the UK runs a monthly trade deficit of £12.3 billion with the bloc.
| Indicator | Value |
| UK Exports to EU (Feb 2026) | £15.2 billion (+2.1% YoY) |
| EU Imports to UK (Feb 2026) | £27.5 billion (+4.9% YoY) |
| UK Trade Deficit with EU | £12.3 billion |
| UK Goods Exports vs 2019 | 16% lower in real terms |
| OBR Long-Run GDP Impact | 4% lower |
| OBR Long-Run Trade Impact | 15% lower |
Real UK goods exports to the EU remain 16% below their 2019 baseline. Furthermore, the British Chambers of Commerce (BCC) expects export growth to slow to a modest 0.3% in 2026. Services exports have similarly flattened, reflecting weaker international demand and added trade hurdles.
The Non-Tariff Barrier Challenge
While zero-tariff rules function as intended, non-tariff barriers present the actual obstacle in UK-EU trade after Brexit. In February 2025, a Scottish Parliament committee inquiry revealed that these administrative hurdles severely damage export volumes.

Customs Declarations SPS Inspections Regulatory Divergence Mobility Rules
(Paperwork & Costs) (Veterinary Checks) (Dual Compliance) (Travel Limits)
Main Administrative Hurdles
-
Customs Bureaucracy: Companies must file full customs declarations for every cross-border shipment, increasing administrative overhead.
-
SPS Inspections: Agri-food exporters face strict Sanitary and Phytosanitary controls. Veterinary inspections add costs and delay perishable shipments, compounded by a lack of mutual recognition for veterinary qualifications.
-
Regulatory Divergence: Because the UK can set its own rules, regulatory standards are drifting apart. Businesses must monitor two different legal systems to remain compliant.
-
Mobility Restrictions: The end of free movement complicates short-term business travel and limits cross-border service supply.
Small and medium-sized enterprises (SMEs) suffer the most from these changes. A late-2025 BCC survey of 989 firms showed that 54% of exporters felt the TCA failed to support their EU sales growth. Only 16% reported positive impacts. As a result, many small manufacturers have ceased exporting to Europe altogether.
The 2026 TCA Review
Article 776 of the TCA mandates a joint review of the agreement five years after implementation. This milestone arrives in 2026, providing a formal platform for both sides to evaluate operational efficiency.
At the Partnership Council meeting on 2 February 2026, officials confirmed their intent to conduct this review while consulting business stakeholders. Although the EU will not permit a complete rewrite of the treaty, the process allows both sides to negotiate targeted adjustments and supplementary deals that reduce unnecessary friction.
The UK-EU Reset and May 2025 Summit
Elected in July 2024, the UK Labour government actively sought to repair diplomatic relations with Brussels. This policy culminated in the landmark UK-EU Summit on 19 May 2025, where both parties agreed to work as closer strategic partners.
Key Agreements from the May 2025 Summit
├── Security & Defence: Partnership link to the €150B SAFE defence fund.
├── Agri-food (SPS): Agreement on dynamic alignment to drop border checks.
├── Energy: Linking ETS carbon markets and electricity trading.
└── Mobility: Launching a young person mobility scheme and rejoining Erasmus+.
Minister for EU Relations Nick Thomas-Symonds highlighted that these agreements could add nearly £9 billion to the UK economy. However, challenges persist. For example, negotiations over financial contributions to the European defence fund remain ongoing, and any new regulatory alignment requires parliamentary approval.
Sectoral Spotlight: Where Friction Bites Hardest
Different industries experience the effects of UK-EU trade after Brexit in distinct ways:
-
Agri-Food: Food producers endure strict certification requirements and physical inspections. At the February 2026 Partnership Council, the UK prioritized restoring the seed potato trade, which has been blocked since 2021.
-
Automotive: Car manufacturers urgently require clear guidance regarding cathode active materials (CAM) ahead of 2027 rule changes.
-
Steel: Safeguards in both markets expire in June 2026, prompting calls for coordinated action to protect interconnected supply chains.
-
Chemicals and Pharma: Regulatory divergence forces chemical manufacturers to register products under both UK REACH and EU REACH regimes, doubling compliance costs.
Looking Ahead for UK-EU Trade
The 2026 review offers a real opportunity to modernize trade arrangements without rejoining the single market or customs union.
Progress will likely focus on an SPS agreement to eliminate food checks, closer integration of energy markets, joint cybersecurity measures, and youth mobility programs. Nevertheless, negotiators must balance these practical solutions against strict political red lines on both sides.
Key Takeaways
-
Zero Tariffs: The TCA prevents tariffs and quotas on compliant goods.
-
Non-Tariff Barriers: Administrative checks and SPS rules remain the largest source of cost and delay.
-
Reduced Trade Volume: Real goods exports sit 16% below 2019 levels.
-
SME Strain: Small exporters struggle to manage compliance costs, leading many to leave the market.
-
2026 Review: The Article 776 review provides a clear mechanism to negotiate targeted improvements.
