Understanding the Data (Use and Access) Act 2025: Compliance & The June 19 Deadline
UK businesses are currently racing against time to meet the imminent June 19, 2026 deadline introduced by the new Data (Use and Access) Act 2025 (DUAA). Under the revised mandates, the Information Commissioner's Office (ICO) has finalized enforcement directives requiring all controllers—regardless of size—to operate public-facing complaints processes.
Failing to provide a statutory compliance framework for data protection complaints is no longer a minor governance oversight. Under the DUAA, it is classified as a severe regulatory violation, exposing independent retailers, consultants, agencies, and corporations alike to steep structural audits and penalty structures.

1. What is the Data (Use and Access) Act 2025?
The Data (Use and Access) Act 2025 (DUAA) is the UK government's latest major update to data privacy and digital governance post-Brexit. It streamlines several elements of the UK GDPR and the Data Protection Act 2018 (DPA) to reduce administrative overhead for businesses, but establishes much stricter consumer protection safeguards in critical areas.
One of the central changes lies in Section 45 (Complaint Handling by Controllers). While previous guidelines allowed businesses to handle privacy inquiries informally, the DUAA codifies complaint resolution into a strict statutory obligation. An individual has the right to file a complaint if they believe the controller has failed to safeguard their personal details, breached transparency rules, or mismanaged a Data Subject Access Request (DSAR).
2. The June 19 Deadline & Compliance Requirements
June 19, 2026 marks the end of the transition period granted by the ICO. By this date, every business acting as a "data controller" (which includes any business processing customer emails, billing details, marketing cookies, or staff payroll) must satisfy three core conditions:
- Public complaints policy: A clearly written document, hosted on your website, outlining the channels, SLA timelines, and procedure to submit complaints.
- Designated handler: A named representative or specific role (such as Data Protection Lead or Representative) assigned to handle complaints.
- Audit-ready internal CSV log: A structured register documenting every complaint received, receipt dates, investigation summaries, and outcome tracking.
ICO Fines & Enforcement
Failing to operate this framework exposes your business to an immediate ICO compliance audit. Statutory fines under the DUAA range up to a maximum of £17.5M or 4% of global turnover, with individual officers held accountable for systemic operational negligence.
3. The 30-Day Acknowledgement Rule
The most significant administrative trap of the new DUAA framework is the **30-Day Acknowledgement Guarantee**. Unlike general customer service complaints, data protection inquiries trigger a strict statutory SLA starting the moment they arrive.
Key parameters of the rule:
Receipt SLA
The business must issue a formal, written acknowledgement confirming receipt of the complaint within 30 calendar days. It must outline investigation steps and specify what identity proof is required.
Resolution Timeline
While resolution timeline is flexible depending on system complexity, investigation must progress "without undue delay," and you must legally provide status updates to the complainant.
If a business fails to send the formal acknowledgement within the 30-day window, the complainant has the immediate right to escalate the dispute directly to the regulator. In such cases, the ICO is statutory-bound to review the controller's internal complaints record ledger.
