Handling Data Protection Complaints in Practice: 10 Lessons from Experience
Posted on in Data Protection
We are seeing a clear increase in subject access request (SAR) responses being challenged and in data-protection-related litigation being threatened. Organisations are often surprised by how quickly a relatively contained issue can escalate, especially where complaint handling is not designed with data protection in mind.
Drawing on our experience advising organisations across a range of sectors, we have identified ten practical lessons that can significantly reduce risk, cost, and management time when handling data protection complaints.
1. A data protection complaints policy is a win-win
A dedicated data protection complaints policy provides clarity for individuals and certainty for organisations. It demonstrates accountability, transparency, and a willingness to engage. These are all key principles under UK GDPR, while giving organisations a structured framework for responding consistently and proportionately.
Importantly, putting a policy in place before a complaint is received is far more cost-effective. It reduces the need for reactive advice and helps prevent issues escalating into management-intensive disputes or regulatory engagement, saving both time and cost in the long run.
2. A dedicated policy helps ring-fence precious management time
In practice, we are frequently instructed by organisations struggling to respond effectively because they rely on standard complaints procedures that are not designed for data protection issues.
A data protection complaint often raises legal, regulatory and evidential issues that require a different approach. A dedicated policy can prevent senior members of staff from being repeatedly drawn into ad hoc decision-making and can be the difference between a contained issue and a regulatory headache.
3. Complaints handling highlights the importance of a well-drafted privacy notice
Individuals are entitled to clear information about how their personal data is processed and who it is shared with. A well-drafted privacy notice can answer many of the questions that arise at the SAR-response and complaint stages, reducing friction and misunderstanding.
Where privacy notices are unclear, outdated or inconsistent with practice, complaints quickly gather momentum. Even straightforward, low-risk processing can attract scrutiny if these fundamentals are missing, and we are seeing a steady rise in complaints.
4. Use complaints as a trigger to review related policies and procedures
Policies should not exist in a vacuum. A data protection complaints policy should align with:
- Privacy notices (public-facing and employee)
- Data protection policies
- Data retention schedules
- Internal guidance and response templates.
Handling a complaint is an opportunity to diarise a focused review and identify gaps or inconsistencies in your compliance before they become systemic risks.
Effective policies require periodic review, updates when the law or guidance changes, and realignment when business practices evolve. A “set and forget” approach is one of the most common compliance failings we see, and it is often exposed during complaints or ICO investigations.
5. Managing expectations is a fundamental part of the complaints process
Many data protection complaints arise not because something has gone wrong, but because expectations were never properly set.
Clear explanations of what data protection law does and does not require, realistic timescales, and proportionate language can significantly reduce dissatisfaction and escalation risk.
In our experience, the dynamic often changes once legal advisers become involved. Organisations may find themselves struggling to manage the status quo, particularly where correspondence becomes lengthy, repetitive or increasingly adversarial.
Tozers can help by:
- Assessing compliance and identifying genuine areas of risk (as distinct from perceived issues)
- Resetting expectations by explaining the legal position clearly and calmly
- Drafting robust, defensible responses that are suitable both for the complainant and, if needed, the ICO;
- Bringing protracted, unproductive exchanges under control before they escalate into regulatory complaints or litigation.
Early legal input can often prevent a complaint from becoming unnecessarily drawn-out, time-consuming and costly.
6. A robust complaint response can avoid escalation to the ICO
A considered, well-reasoned and evidence-based complaint response is often enough to prevent escalation.
Where individuals feel listened to and understand the rationale behind a decision –even if they disagree – regulatory complaints are less likely to follow, as ICO may decide there is no case to investigate.
7. If escalation does happen, you are better placed to respond to the ICO
If a complaint is referred to the ICO, your earlier response often forms the foundation of your regulatory engagement.
A structured complaints process ensures you already have:
- A clear audit trail
- Consistent reasoning
- Appropriately framed explanations.
This can materially influence the ICO investigator’s assessment of risk and proportionality.
8. Drafting matters!
Be cautious with language in your complaints policy and privacy notices, such as:
- “We always…”
- “We will never…”
- “We ensure full compliance…”
These statements can create unnecessary exposure if reality falls short. Proportionate, accurate wording allows for operational flexibility and better reflects how data protection law is applied in practice.
9. Copying another organisation’s complaints policy is a risk
Copying another organisation’s policy can seem like a quick fix, but it carries legal and practical risks.
- There may be copyright implications
- The policy may not reflect your systems, data flows, or staff roles
- A policy that does not match reality can undermine credibility with complainants and regulators.
Policies should be bespoke, operational and defensible. What saves time initially often increases regulatory risk and cost in the long run.
10. Compliance doesn’t end with the implementation of a complaints policy
A policy only protects you if it is understood, followed and embedded into day-to-day practice.
If you cannot evidence training, awareness and consistent application, a complaints policy may count against you rather than in your favour.
