UK GDPR Complaints Procedure Template: Compliance Guide

Under the **UK GDPR** and the updated mandates of the **Data (Use and Access) Act 2025 (DUAA)** coming into force on **19 June 2026**, data controllers must operate public data complaints channels. A standardised **UK GDPR complaints procedure template** is the fastest path to ensure full readiness.

Interaction Between UK GDPR and the DUAA 2025

The DUAA 2025 amends several provisions of the UK GDPR and the Data Protection Act 2018. While the UK GDPR establishes fundamental data subject rights (such as access, rectification, and consent withdrawal), the DUAA codifies complaints handling. Specifically, Section 103 of the DUAA inserts Section 164A into the DPA 2018, establishing a statutory duty for controllers to acknowledge complaints in writing within **30 calendar days** and investigate them without undue delay.

Essential Components of the Procedure Document

A compliant complaints procedure document must detail the operational pipeline:

• Submission Channels: Accepting data protection complaints raised via email, web portal, or post.
• Receipt SLA: Formal written confirmation within the mandatory 30-day statutory timeline.
• Outcomes & Remedies: Written notification detailing investigation findings, actions taken, and rights of escalation.

Reducing Scrutiny and Escalation

Failing to have a complaints process may increase regulatory risk, ICO scrutiny, and the likelihood of escalation. Using a pre-formatted template avoids the cost of bespoke solicitor reviews, which typically start at £400.

The DUAA Shield complaints policy pack provides small organisations with a practical, ready-to-adapt starting point for a one-time £20 fee.
