Post-Brexit Trade Rules in 2026: The Business Landscape
More than three years since the UK-EU Trade and Cooperation Agreement (TCA) took full effect, post-Brexit trade arrangements continue to evolve. New border controls, customs procedures and financial services access rules have changed the operating environment for UK businesses trading with Europe. Understanding the framework is essential for managing compliance costs.
- The TCA provides zero tariffs on goods with sufficient UK or EU content - but customs declarations are required for all goods movements.
- The UK Border Target Operating Model (BTOM), implemented in 2024, introduced new import controls for EU goods entering Great Britain.
- UK financial services firms lost EU passporting rights. Operating in EU markets now requires local authorisation or third-country access frameworks.
- The Windsor Framework governs UK-EU arrangements for Northern Ireland - different rules apply for goods moving between GB and NI.
Customs and Tariffs: The Current Framework
Under the TCA, goods originating in the UK or EU move tariff-free between the two blocs provided they meet Rules of Origin requirements. Customs declarations are required for all goods movements - unlike the pre-Brexit position - creating administrative costs and border friction. Rules of Origin require a specified percentage of content to originate in the UK or EU. Businesses sourcing components from outside both blocs need to check whether their products qualify.
UK Border Target Operating Model
The BTOM, implemented in 2024, introduced a risk-based approach to import controls for EU goods entering Great Britain: safety and security declarations for most EU imports; health certificates and physical checks for high-risk food and feed products; Common User Charge at certain ports for official controls on animal and plant products. HMRC and APHA publish detailed guidance at gov.uk.
Financial Services: Post-Brexit Access
UK financial services firms lost EU passporting at the end of the transition period. Firms previously relying on passporting to serve EU clients now need local authorisation in EU member states or reliance on available third-country access frameworks (which vary by jurisdiction and product type). The FCA maintains the UK Financial Services Register at fca.org.uk/firms/financial-services-register.
VAT on Cross-Border Sales
UK businesses selling goods to EU consumers must comply with EU VAT rules above relevant thresholds. The EU One Stop Shop (OSS) allows non-EU businesses to register for VAT in a single member state and account for all EU VAT through one return. HMRC guidance is at gov.uk/guidance/vat-and-overseas-goods-sold-directly-to-customers-in-the-eu.
Frequently Asked Questions
Do UK goods face tariffs when exported to the EU?
Under the TCA, goods meeting Rules of Origin requirements export to the EU tariff-free. If Rules of Origin conditions are not met, standard EU Most Favoured Nation tariff rates apply. Check the UK Global Tariff and EU Common External Tariff for your product codes.
Does the Windsor Framework affect English businesses?
If your business moves goods between Great Britain and Northern Ireland, the Windsor Framework governs those movements. For businesses operating only in England, Scotland or Wales and not moving goods to NI, the Windsor Framework does not directly apply.
What is the Common User Charge?
The Common User Charge applies at certain UK ports including Dover for official biosecurity controls on animal and plant products imported from the EU. Charges began from 30 April 2024. Gov.uk publishes the current charge schedule by product type and weight.
Where can businesses get help with post-Brexit compliance?
The Department for Business and Trade (gov.uk/government/organisations/department-for-business-and-trade) provides guidance and support. HMRC customs helpline and UK Trade Info cover tariffs and customs procedures. British Chambers of Commerce and trade associations provide sector-specific guidance.
