GDPR vs UK GDPR: What's the Difference?

How the two regimes separated

At the end of the Brexit transition period, the UK retained a domestic version of the EU GDPR. The UK GDPR now operates alongside the Data Protection Act 2018, while the EU GDPR continues to apply across the European Economic Area under EU law. Their principles, lawful bases, and individual rights remain closely aligned.

The current UK reform statute is the Data (Use and Access) Act 2025 (DUAA). Earlier bills with different names did not become the final law. Most of the DUAA's data-protection and privacy amendments came into force on 5 February 2026.

Key differences at a glance

The UK analytics exception is narrow

Cookie consent is not governed by the GDPR alone. In the UK, PECR regulates storing information on or accessing information from a person's device. The DUAA added a statistical-purposes exception. Under current ICO guidance, an operator may rely on it only when the sole purpose is to collect statistical information about use of its service or website with a view to improving it.

The resulting statistics must be aggregate information that does not identify people. Individual-level information must not be kept longer than needed for aggregation. The operator must provide clear and comprehensive information and a simple, free way to object. A third-party analytics provider may assist only on the operator's behalf and only for that improvement purpose.

The exception does not cover advertising, ad measurement, profiling, monitoring individual visitors, cross-site tracking, or linking a visitor's activity to advertising data. If one technology serves both qualifying statistics and another purpose, consent is still required. Marketing and advertising technologies continue to require consent under PECR.

EU member states implement the ePrivacy Directive through national law and regulator guidance. Non-essential analytics generally requires prior consent, but the detailed position and any narrow audience-measurement exemption vary by country. A site operating across multiple EU countries should not treat either the UK exception or one member state's guidance as an EU-wide rule.

What else the DUAA changed

The DUAA made targeted changes rather than replacing the UK GDPR. Among other things, it added recognised legitimate interests for specified public-interest purposes, allowed the response period for certain subject access requests to pause while reasonably required clarification is outstanding, and broadened the circumstances in which solely automated significant decisions may be made when safeguards are provided.

It did not generally replace data protection officers with a new “Senior Responsible Individual” role. Organizations should continue to assess the existing UK GDPR rules that determine whether a data protection officer is required.

Data transfers between the EU and UK

The European Commission renewed the UK's EU GDPR adequacy decision in December 2025. That decision currently allows personal data to flow from the EEA to the UK without an additional transfer safeguard. UK adequacy regulations likewise cover transfers from the UK to the EEA.

For transfers to other destinations, each regime has its own tools. An EU exporter may use the EU Standard Contractual Clauses when appropriate. A UK exporter may use the UK International Data Transfer Agreement or pair the EU clauses with the UK Addendum. The EU clauses alone are not a UK transfer mechanism, but they can form part of one through that Addendum.

When might both regimes apply?

A website's mere accessibility from the EU or UK does not by itself make both regimes apply. Scope depends on facts such as where the organization is established and whether it offers goods or services to, or monitors the behavior of, people in the relevant territory.

If both regimes apply, check these points separately:

• Identify the correct regulator and complaint route for each affected person.
• Use the transfer mechanism required by the exporter's regime and the destination's adequacy status.
• Assess whether separate EU and UK representatives are required; exemptions may apply.
• Evaluate each cookie or similar technology by purpose, data use, user controls, and the applicable national rule.

Why this matters for your website

Legal analysis starts with technical facts. A site may load third-party cookies, tracking pixels, scripts, or local-storage identifiers that serve several purposes. Their names do not determine whether consent or an exception applies.

Tagmaps scans a website from selected locations, exercises consent choices, and records which technologies and requests appear in each state. That evidence helps your team assess the applicable rules; it is not a legal determination by itself.
