UK GDPR vs EU GDPR: Key Differences Every Business Must Know in 2026

Two GDPRs, One Compliance Headache

When the UK left the EU, it retained the GDPR framework by incorporating it into domestic law — creating the UK GDPR. At the moment of Brexit in January 2021, the two frameworks were identical.

Since then, they have been steadily diverging. With the Data Use and Access Act (DUAA) 2025 coming into force on 5 February 2026, the gap has widened significantly. If your business operates in both the UK and the EU — or serves customers in both — you now have two distinct compliance frameworks to manage.

This is not a minor technicality. Getting it wrong means regulatory exposure on both sides of the Channel.

The Governing Framework

| | EU GDPR | UK GDPR |

|--|---------|---------|

| Legal basis | Regulation (EU) 2016/679 | UK GDPR + Data Protection Act 2018 + DUAA 2025 |

| Enforcer | National DPAs (coordinated by EDPB) | Information Commissioner's Office (ICO) |

| Max fine | €20 million or 4% of global turnover | £17.5 million or 4% of global turnover |

| Binding guidance | European Data Protection Board (EDPB) | ICO (EDPB guidance not binding in UK) |

Key Differences in 2026

1. Automated Decision-Making

EU GDPR: Article 22 gives individuals strong rights to object to and request human review of solely automated decisions that significantly affect them (e.g. credit scoring, recruitment screening).

UK GDPR (post-DUAA): The restrictions on automated decision-making are narrower. Article 22 UK GDPR has been amended so that automated decisions are permitted in more circumstances, provided appropriate safeguards are in place. The practical effect is that UK businesses have somewhat more flexibility when using AI-driven decision tools — but safeguards are still mandatory.

Practical impact: If you use AI for hiring, credit assessment, or customer profiling, your UK and EU processes may need to differ.

2. Legitimate Interests — Recognised List

EU GDPR: To rely on "legitimate interests" as a legal basis for processing, organisations must conduct a full Legitimate Interests Assessment (LIA), balancing their interests against the rights of data subjects.

UK GDPR (post-DUAA): A list of "recognised legitimate interests" has been introduced, allowing organisations to rely on legitimate interests for specified purposes without conducting a full LIA. Examples include fraud prevention, network security, and safeguarding.

Practical impact: UK businesses processing data for certain common commercial purposes may have a simplified compliance path. EU operations still need full LIAs.

3. Internal Complaints Procedure

EU GDPR: No formal requirement for an internal complaints handling process.

UK GDPR (post-DUAA): Organisations must have an internal complaints procedure and must facilitate and respond to data subject complaints through it.

Practical impact: UK-facing privacy policies and procedures must now reference a formal internal complaints process and how individuals can use it.

4. International Data Transfers

EU GDPR: Data transfers outside the EU/EEA require adequacy decisions, Standard Contractual Clauses (SCCs), Binding Corporate Rules, or another approved mechanism.

UK GDPR: The UK has its own adequacy framework. The UK has granted adequacy to the EU/EEA (meaning EU-to-UK transfers are permitted). However, the EU's adequacy decision for the UK — granted in 2021 — was time-limited and is subject to renewal. Its current status should be verified regularly.

For transfers from the UK to third countries, the UK uses International Data Transfer Agreements (IDTAs) or an Addendum to EU SCCs — not EU SCCs directly.

Practical impact: Any business using EU-standard SCCs for UK data transfers may need to update its transfer mechanisms.

5. DPO (Data Protection Officer) Requirements

Both frameworks require a DPO for organisations that process personal data at large scale, carry out systematic monitoring, or process special category data. However, the DUAA introduces the concept of a Senior Responsible Individual (SRI) as an alternative to a DPO for public bodies — not directly relevant to most private businesses but worth noting.

6. Cookie Consent

Both frameworks require explicit consent for non-essential cookies under their respective ePrivacy laws (EU ePrivacy Directive / UK PECR). However:

The ICO and EDPB issue separate guidance that sometimes diverges on specifics

The UK is expected to further reform PECR, which could simplify cookie consent requirements for UK-only websites

For now, a consent management platform that handles both UK and EU requirements is the safest approach.

Do You Need to Comply With Both?

You need EU GDPR compliance if:

You have an establishment in the EU

You offer goods or services to people in the EU

You monitor the behaviour of people in the EU

You need UK GDPR compliance if:

You have an establishment in the UK

You offer goods or services to people in the UK

You monitor the behaviour of people in the UK

Most businesses serving both markets need both frameworks. This includes many Cyprus-based businesses that serve UK clients.

Practical Steps for Dual Compliance

Audit your data flows — identify which data relates to EU data subjects and which to UK data subjects

Review your Privacy Policy — it must accurately reflect both frameworks if you serve both markets; some businesses maintain separate UK and EU privacy notices

Check your data transfer mechanisms — are you using EU SCCs or UK IDTAs where required?

Review automated decision-making processes — document safeguards for both regimes

Update your internal complaints procedure — required under UK GDPR now

Appoint a UK representative if you are an EU-based business processing UK personal data without a UK establishment (and vice versa)

The Bottom Line

The Data Use and Access Act 2025, now in force, makes UK GDPR compliance a genuinely separate exercise from EU GDPR compliance. Treating them as identical is no longer defensible.

If your business serves customers in both the UK and the EU, a compliance review against both frameworks is now essential — not optional.
