Data Protection Complaint Acknowledgement and Response Letter 
This Data Protection Complaint Acknowledgement and Response Letter is designed for use where an organisation can acknowledge a data protection complaint and provide its outcome at the same time.
It combines the acknowledgement of receipt with your response, making it suitable for simpler complaints that can be investigated and resolved within the acknowledgement period.
Note: While structured as a letter, this template can be easily adapted for use as an email or direct message response.
When Should This Letter Be Used?
This letter should be used when you have received a complaint about the handling of personal data and you are able to investigate the complaint and provide its outcome promptly.
It is suitable for straightforward complaints where you do not need to send a separate acknowledgement letter before completing your investigation.
If you need to acknowledge the complaint but cannot yet provide the outcome, use the Data Protection Complaint Acknowledgement Letter instead.
What Does This Letter Cover?
This Data Protection Complaint Acknowledgement and Response Letter provides a complete response for complaints that can be dealt with quickly:
- Receipt and reference details
- A summary of the complaint
- Details of your investigation
- Details of the actions you have taken or propose to take
- Provisions giving complainants the option to request a review of the outcome, clarify it, or complain to the ICO
Legal and Compliant
This Data Protection Complaint Acknowledgement and Response Letter is designed to support compliance with UK data protection law, including the UK GDPR, the Data Protection Act 2018, and the Data (Use and Access) Act 2025.
It helps organisations deal efficiently with complaints that can be investigated and responded to within the acknowledgement period, while still giving the complainant a clear explanation of the complaint outcome and their right to complain to the ICO.
How Should This Template Be Used?
This letter should be adapted to include the organisation’s name, contact details, complaint reference, summary of the complaint, investigation steps, findings, outcome, and any action taken or proposed.
It should be used only where you are ready to provide the outcome of the complaint at the same time as acknowledging receipt. Where further investigation is required, the standard Data Protection Complaint Acknowledgement Letter should be used instead.
