You're likely aware of the significant impact that the General Data Protection Regulation (GDPR) has had on businesses worldwide. However, the United Kingdom's exit from the European Union, commonly known as Brexit, has raised questions about the future of GDPR in the UK. This article will delve into the implications of Brexit on GDPR and what it means for your eCommerce business. The Impact of Brexit on GDPR Brexit officially took place on January 31, 2020, after months of negotiations and mixed reactions. During the transition period that lasted until December 31, 2020, EU GDPR continued to apply in the UK. However, with the UK exiting the EU and falling outside of the GDPR zone, it became a "third country" with restrictions on data flow between the two sides. To ensure the free flow of data, the EU and UK signed a deal that allowed uninterrupted data flow for six months starting from January 1, 2021. Following that, on June 28, 2021, the EU adopted an adequacy decision↗ for the UK to allow uninterrupted data flow from the EU without further supervisory authorization or legal measures for four years (until June 2025). The UK GDPR 2021 To fulfill the Withdrawal Agreement for providing the EU equivalent level of data protection, the UK government amended the EU GDPR and created a new domestic law called UK GDPR to replace the former. Businesses based in or outside the UK that have been previously following the EU GDPR for processing the UK users' personal data now have to comply with the UK GDPR requirements. Also, those that are offering goods and services to EU users should continue to follow the EU GDPR. The Amended Data Protection Act (DPA) 2018 The DPA 2018 was once again amended on January 1, 2021, after the UK's transition period after Brexit. The DPPEC merged the EU GDPR rules to create a new data protection regime known as the UK GDPR. What Happens to GDPR After Brexit? The EU GDPR is the most robust and stringent data protection law that affects a lot of businesses worldwide. Even after Brexit, there are a few notable changes that you may want to be aware of: - Businesses operating in the UK, offering goods and services to UK individuals are no longer required to follow the EU GDPR. They have to align all their policies and privacy practices with the UK GDPR.
- UK businesses operating in the EU, offering goods and services to EU individuals must continue to follow the EU GDPR along with the UK GDPR.
- ICO is no longer the UK regulator for any EU GDPR-related concerns. It is the independent supervisory body for UK data privacy laws↗.
- Data transfer from the UK to the EU will be subject to the UK International Data Transfer laws and EU SCCs. UK International Data Transfer Post Brexit On February 2, 2022, the Secretary of State issued the International Data Transfer Agreement (IDTA), the Addendum to EU SCCs, and transitional provisions under Section 119A of the Data Protection Act 2018. The IDTA allows for international transfers of data from the UK to countries with equivalent data privacy laws. GDPR and Brexit: The Future On May 10, 2022, the UK government announced that it will be introducing a Data Reform Bill. The Bill will create a new, more agile regulatory regime that minimizes the bureaucratic time and cost burden placed on SMEs while giving them the tools they need to thrive. It will also make UK citizens’ data rights stronger than ever before, helping to give them greater control over how companies use their personal data.
How Brexit Affects Your Data Processing Agreements
If your eCommerce brand processes data from both UK and EU customers, you now need separate legal frameworks in place. Your Data Processing Agreements (DPAs) with vendors like Shopify, Klaviyo, or analytics tools must reflect whether you're handling UK data, EU data, or both.
Many eCommerce platforms automatically updated their standard contracts post-Brexit, but you should verify your current agreements cover both jurisdictions. If you use third-party apps for email marketing, customer reviews, or analytics, check that your vendor has executed the appropriate Standard Contractual Clauses (SCCs) for UK transfers. The EU's SCCs include the UK Addendum, which governs data movement between the UK and EU.
Your payment processor, shipping integrations, and customer support tools all handle personal data. Each integration needs clear documentation showing how data flows across borders. If a vendor hasn't updated their contracts since January 2021, that's a red flag — they may not be compliant with current UK-EU transfer requirements.
Document everything. Keep records of which vendors process which customer data and under which legal basis. This protects you if the Information Commissioner's Office (ICO) or an EU regulator audits your compliance.
Cookie Consent and Regional Compliance
Your cookie banner isn't a one-size-fits-all solution anymore. UK and EU regulations both require consent before placing non-essential cookies, but the rules have subtle differences in how consent is collected and managed.
In the EU, cookies fall under ePrivacy Directive rules in addition to GDPR. In the UK, the Privacy and Electronic Communications Regulations (PECR) govern cookies. Both require explicit, informed consent, but the technical implementation may differ slightly depending on your analytics setup (Google Analytics, Shopify tracking, Meta Pixel, etc.).
If your Shopify store serves both UK and EU visitors, your cookie banner should allow users to choose their region or language — and your consent settings should adjust accordingly. Some cookie management platforms automatically detect location and apply the right ruleset, but verify this is working correctly. Test your banner from both UK and EU IP addresses to ensure the correct consent options appear.
Post-Brexit Data Breaches and Notification Requirements
Data breach notification timelines differ slightly between UK GDPR and EU GDPR. Both require notification within 72 hours to the relevant authority, but the UK's ICO and EU's DPAs may have different escalation procedures.
If your eCommerce brand experiences a breach affecting both UK and EU customers, you must notify both the ICO and the relevant EU Data Protection Authority (usually in the country where affected customers are located). Keep your incident response plan updated to reflect these dual-notification requirements.
Your customers expect clarity about which regulator handles their data. Transparency builds trust — especially in a post-breach scenario.
As your eCommerce operation grows across UK and EU markets, managing dual compliance frameworks becomes increasingly complex. Consent management, data transfer agreements, and breach protocols all require careful tracking to avoid costly fines and reputational damage. A dedicated consent and compliance platform can automatically enforce regional rules, document your processing activities, and help you respond quickly when regulations change.
