DPA 2018: UK GDPR Implementation
UK GDPR Implementation [Sections 6-20]
Rule: Part 2 Chapter 2 provides the UK-specific implementation of the UK GDPR, including definitions, lawfulness bases, special categories processing conditions, certification, exemptions, and safeguards.
Purpose of These Sections
While the UK GDPR is directly applicable law, sections 6-20 of the DPA 2018:
- Define UK-specific terms and concepts
- Specify conditions for processing special categories
- Create additional lawful bases
- Establish exemptions and restrictions
- Provide safeguards for specific processing types
Definitions [Sections 6-7]
Section 6: Meaning of “Controller”
The UK GDPR definition of controller applies with this modification:
| Situation | Who is Controller | Citation |
|---|---|---|
| Processing required by law | Where enactment requires processing with prescribed means | Person on whom obligation is imposed |
| Normal circumstances | UK GDPR Article 4(7) applies | Person determining purposes and means |
Example:
- Companies House must collect company information in specified format
- Controller: Companies House (not the company submitting data)
- Rationale: Law prescribes purposes and essential means
Practical impact:
- Statutory data collection schemes have clear controller designation
- Organizations fulfilling legal obligations may not be controllers
- Important for determining responsibilities
Section 7: Meaning of “Public Authority” and “Public Body”
For UK GDPR purposes, “public authority” means:
| Category | Description | Citation |
|---|---|---|
| FOIA bodies | Public authorities under Freedom of Information Act 2000 | s.7(1)(a) |
| Scottish equivalents | Bodies under Scottish FOIA | s.7(1)(b) |
| ARIA | Advanced Research and Invention Agency | s.7(1)(c) |
| Secretary of State designation | Bodies specified by regulations | s.7(1)(d) |
Important limitation (s.7(2)): Public authority designation applies only when:
- Performing tasks in public interest, or
- Exercising official authority
Practical significance:
- Affects Article 6(1)(e) lawful basis availability
- Determines when consent cannot be freely given (imbalance of power)
- Influences DPO appointment requirements
- Relevant for transparency obligations
Not public authorities for all purposes:
- NHS Trust running commercial services (commercial activity only)
- University conducting private research (research activity only)
- Council-owned company (trading activities)
Lawfulness of Processing [Section 8]
Section 8: Public Interest Processing
Expands Article 6(1)(e) (processing necessary for public interest task or official authority exercise).
Additional public interest bases:
| Basis | Description | Examples |
|---|---|---|
| Administration of justice | Supporting judicial system | Court admin, tribunal processing |
| Parliamentary functions | Legislative and oversight activities | Hansard, committee inquiries |
| Statutory functions | Carrying out functions conferred by statute | Regulatory bodies, statutory inspectorates |
| Crown functions | Exercise of Crown functions | Government departments, Crown services |
| Democratic engagement | Supporting democratic processes | Electoral registration, petitions |
Practical application:
- Government agencies using this basis for statutory functions
- Parliamentary processing of correspondence and investigations
- Courts processing case management data
- Electoral registration officers processing voter data
Requirements:
- Must be necessary for the specific function
- Must be proportionate
- Alternative bases may be more appropriate in some cases
- Document reliance on this basis
International Law Processing [Section 9A]

Practical Compliance
For Controllers Processing Special Categories
Checklist:
- ✅ Identify Article 6 lawful basis
- ✅ Identify Schedule 1 condition
- ✅ Prepare Appropriate Policy Document (if Schedule 1 Part 2)
- ✅ Maintain records of processing
- ✅ Implement technical safeguards
- ✅ Train staff on special categories handling
- ✅ Review and update APD regularly
For Public Authorities
Considerations:
- Determine if acting in public interest capacity
- Document reliance on Article 6(1)(e)
- Specify statutory basis clearly
- Consider if consent can be freely given (power imbalance)
- Apply public authority-specific obligations
- Enhanced transparency expectations
For Researchers
Key points:
- Apply appropriate safeguards (s.19)
- Rely on Schedule 2 Part 6 exemptions where applicable
- Document necessity of processing identifiable data
- Implement pseudonymisation/anonymisation where possible
- Establish ethics review processes
- Balance research value against individual rights
- Prepare for Commissioner oversight
For International Transfers
Compliance steps:
- Check if destination has adequacy decision (s.17A)
- If not adequate, identify appropriate safeguard:
- Commissioner’s standard clauses (s.17C)
- Binding corporate rules
- Approved codes/certifications
- Article 49 derogations (exceptional circumstances)
- Implement supplementary measures if needed
- Document transfer basis
- Inform data subjects
- Monitor Commissioner guidance on adequacy
Common Pitfalls
Assuming all government processing is public interest:
- Section 7 limits when public authority designation applies
- Commercial activities not covered
- Must genuinely be public interest task
Relying on Schedule 1 without APD:
- Schedule 1 Part 2 conditions require Appropriate Policy Document
- Failure to maintain APD = non-compliance
- Must be available to Commissioner on request
Overlooking exemptions:
- Schedule 2-4 provide valuable exemptions
- Must apply proportionately
- Document necessity
Inadequate safeguards for research:
- Section 19 requires appropriate safeguards
- Cannot assume research = automatic exemption
- Balance research value with data protection
