How do I handle data subject complaints?

Q34. How do I handle data subject complaints?

Category: Complaints

Handling data subject complaints well demonstrates respect and may prevent escalation to the ICO.

In simple terms

  • Acknowledge complaints quickly and investigate fairly.
  • Keep records of actions taken and communicate clearly.
  • Learn from complaints to improve processes.

Complaint handling process

Design a transparent process that logs complaints, assigns responsibility, and tracks deadlines.

  • Respond within a reasonable timeframe, usually one month.
  • Provide updates if investigations take longer.
  • Explain outcomes clearly, referencing relevant policies or evidence.

Escalation and learning

If the individual remains unhappy, signpost the ICO. Use complaints to identify root causes and improve training or controls.

  • Record corrective actions and monitor their effectiveness.
  • Share anonymised lessons with leadership or the board.
  • Incorporate feedback into future privacy risk assessments.

Practical steps to take

  1. Create a central log for complaints and compliments.
  2. Assign a trained handler to each new complaint.
  3. Gather evidence from systems, staff, and partners involved.
  4. Reply in plain language, addressing each issue raised.
  5. Offer the right to escalate to the ICO if the person is dissatisfied.

Real-life examples

Marketing complaint

An individual complains about unwanted emails. The organisation apologises, removes the address from marketing lists, and explains how the error happened.

SAR response complaint

A customer says their SAR was incomplete. The company investigates, finds missing data, sends an updated response, and revises its SAR checklist.

Helpful reminders

  • Keep complaint records securely and respect confidentiality.
  • Use complaints as indicators of potential systemic issues.
  • Train frontline staff to recognise when a grievance is a data protection complaint.

Key takeaway

Handle complaints with care—quick, fair responses maintain trust and reduce regulatory risk.
