Complaining to the DPC, Step by Step
4 March 2026 · Mary Molloy Solicitors
A DPC complaint is free, does not require a solicitor, and works best when it is built like a short case file rather than a letter of grievance. Here is the sequence that produces complaints the DPC can act on quickly.
Before the complaint
Raise the issue with the organisation first and keep everything: your request or objection, its response or silence. The DPC expects this step, and the organisation's own words become your best exhibit. Give it a genuine short opportunity to fix the problem — a cured infringement may end the matter, and an uncured one strengthens the file.
Building the complaint
Three components: a chronology (dated events in order, one line each), the documents (attached in the same order, labelled), and the ask (compliance, a finding of infringement, correction of practice). Name the right engaged — access, erasure, unlawful disclosure — and resist the urge to include the whole history of your relationship with the organisation. Precision is speed.
What happens then
Expect acknowledgment, possible routing to amicable resolution (where a large share of individual complaints conclude — suddenly your request is answerable), and in contested matters a longer examination. Timescales run months for the simple and much longer for the complex. Remember the boundary: the DPC can direct and sanction, but compensation for your damage comes only through a court claim — which can run alongside, and which a DPC finding can support.
