UK GDPR Document Redaction
AI-powered redaction to help you comply with UK data protection law. Protect personal data, respond to DSARs, and avoid ICO enforcement.
What UK GDPR Requires
The UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018 require organisations to protect personal data throughout its lifecycle. This includes proper redaction when sharing documents or responding to data subject requests.
Data Subject Access Requests
When fulfilling DSARs, you must provide all personal data about the requester while redacting information that identifies other individuals. Proper redaction is essential to avoid breaching third-party privacy.
Document Sharing
Before sharing documents externally—with partners, regulators, or in legal proceedings—personal data not relevant to the purpose must be redacted to comply with data minimisation principles.
Data Retention
Personal data must not be kept longer than necessary. Where documents must be retained but personal data is no longer needed, redaction provides a compliant alternative to deletion.
Legal Proceedings
Court filings, tribunal submissions, and legal discovery often require redaction of irrelevant personal data. UK courts expect proper protection of third-party information.

ICO Enforcement Is Real
The Information Commissioner's Office actively enforces UK GDPR. In 2024 alone, the UK reported 27,829 data breaches. Recent enforcement actions demonstrate the ICO's willingness to issue significant fines.
Recent ICO Fine: £3.1 Million
In 2024, the ICO fined Advanced Computer Software Group £3.1 million for inadequate security that led to a ransomware attack. The breach compromised personal data of 79,404 individuals and disrupted NHS services.
The ICO found failures in multi-factor authentication, vulnerability scanning, and patch management. This was the first penalty imposed on a data processor under UK GDPR.
Key Legislation You Must Know
UK data protection is governed by two overlapping frameworks post-Brexit.
UK GDPR
The retained EU GDPR, tailored for the UK via the European Union (Withdrawal) Act 2018. Mirrors EU GDPR but enforced independently by the ICO.
Article 5(1)(c): Data minimisation — personal data must be limited to what is necessary.
Article 15: Right of access — you must redact third-party information in SAR responses.
Article 17: Right to erasure — redaction is often the practical compliance method.
Data Protection Act 2018
The UK's domestic legislation supplementing UK GDPR. Adds UK-specific provisions.
Schedule 2: Exemptions for management forecasting and negotiations.
Part 3: Separate rules for police and criminal justice bodies.
Section 45: Third-party data in SAR responses — redact and release, don't withhold entirely.
ICO Penalty Framework
Up to £8.7M
or 2% of global turnover
Standard Maximum
For infringements of controller/processor obligations.
Up to £17.5M
or 4% of global turnover
Higher Maximum
For infringements of data processing principles, consent, and data subjects' rights.
£12.7M
TikTok (2023) — children's data
£4.4M
Clearview AI (2022) — facial images
£750K
Ministry of Defence (2023) — email breach
Subject Access Requests: The Redaction Trigger
30 Calendar Days to Respond
Under UK GDPR Article 12(3), you have one month. Extensions up to two additional months are possible for complex requests, but you must inform the requester within the first month.
Third-Party Data Must Be Redacted
Section 45 of the DPA 2018: redact third-party details and release the rest. The ICO expects surgical redaction, not wholesale withholding of documents.
Volume Is Growing
SAR complaints to the ICO have increased significantly year-over-year. Automated PII detection reduces processing time from days to minutes per document batch.
