Brexit's Impact on UK Law: Key Changes & Updates

Brexit has heralded a significant transformation for the UK, with far-reaching implications across various sectors. One of the most affected areas is the legal landscape. As Pro Legal, we’re here to untangle the complexities and provide you with a clear understanding of the key changes and updates in UK law post-Brexit.

Trade Law

The departure from the European Union has necessitated a revamp of the UK's trade laws. The UK is no longer bound by EU trade agreements, paving the way for new bilateral agreements. This shift has introduced both opportunities and challenges for businesses operating within and outside the UK.

  • New Trade Agreements: The UK has secured agreements with numerous countries, including Japan and Australia, fostering a more globally competitive market.
  • Customs and Tariffs: Businesses must now navigate a new customs regime, with different tariffs and regulations compared to the previous EU framework.

Customs and Tariffs

Customs regulations have undergone substantial changes. The UK Global Tariff (UKGT) replaces the EU's Common External Tariff, which means businesses must adapt to new procedures and documentation requirements.

Immigration Law

Brexit has also reshaped the UK's immigration policies. With the end of free movement, the UK has implemented a points-based immigration system, impacting both individuals and employers.

  • Skilled Workers: The new system prioritises skilled workers, making it essential for prospective immigrants to meet specific criteria.
  • Employers: Businesses must now sponsor foreign employees, adhering to stricter guidelines and ensuring compliance with the new rules.

Skilled Workers

The points-based system requires skilled workers to accumulate points based on factors such as job offer, salary, and English proficiency. This shift aims to attract talent that contributes positively to the UK economy.


Employers face new obligations, including obtaining a sponsor licence and conducting rigorous checks to ensure their foreign employees meet the necessary criteria. Failure to comply can lead to severe consequences, including hefty fines.

Financial Services Law

The financial sector, a cornerstone of the UK economy, has also experienced substantial changes. The loss of 'passporting' rights has compelled UK financial institutions to rethink their strategies for operating within the EU.

  • Passporting Rights: UK-based financial firms can no longer automatically offer services across the EU, requiring them to establish new bases within EU member states.
  • Equivalence: The UK seeks to secure equivalence agreements with the EU to ensure mutual recognition of regulatory standards, though this remains a complex and ongoing process.

Passporting Rights

Previously, UK financial firms enjoyed the ability to 'passport' their services across the EU. The cessation of these rights necessitates establishing subsidiaries within the EU to continue operations seamlessly.


Equivalence agreements aim to align regulatory standards between the UK and the EU. These agreements are critical for maintaining access to each other's financial markets, although achieving them is an intricate and politically sensitive task.

Data Protection Law

Data protection has been another crucial area of focus post-Brexit. While the UK has retained the General Data Protection Regulation (GDPR) standards, there are notable adjustments that businesses must heed.

  • GDPR Retention: The UK has incorporated GDPR into domestic law with minor amendments, ensuring a high level of data protection continues.
  • Data Transfers: New rules govern data transfers between the UK and the EU, requiring businesses to implement additional safeguards to ensure compliance.

GDPR Retention

The adoption of GDPR into UK law, referred to as 'UK GDPR', maintains stringent data protection standards. However, businesses must stay informed about any future divergences that may arise due to legislative changes.

Data Transfers

Data transfers between the UK and the EU are now subject to new regulations. Businesses must employ mechanisms such as Standard Contractual Clauses (SCCs) to ensure lawful data flow across borders.


Brexit has undeniably transformed the UK's legal environment, prompting businesses and individuals to recalibrate their strategies and operations.
