Practical example


ABC Limited, a multinational company based in the UK, receives a Subject Access Request (SAR) from one of its former employees, Sarah Thompson. Sarah, who left the company six months ago, has requested access to all personal data held by the company relating to her employment.

Initial Response

Upon receiving Sarah's SAR, the HR department promptly acknowledges receipt and begins the process of gathering the requested information. However, due to the complexity of Sarah's employment history and the volume of data involved, the HR team realises that they may need more time to fully comply with the request.

Need for Extension

As the deadline for responding to SARs under GDPR approaches, the HR manager, David, assesses the progress made in collating Sarah's data. Despite their best efforts, the team realises that they require additional time to ensure they provide a comprehensive response without overlooking any relevant information.

Drafting the SAR Extension Letter

David drafts a SAR Extension letter addressed to Sarah Thompson, acknowledging receipt of her request and expressing the company's commitment to fulfilling it in accordance with GDPR regulations. The letter explains the reasons for the extension, citing the volume and complexity of the data involved, and assures Sarah that her request remains a priority.

Content of the Letter

In the SAR Extension letter, David provides a new deadline for responding to Sarah's request, extending it by an additional 30 days as permitted by GDPR regulations. He also includes contact details for any further inquiries Sarah may have regarding her SAR.

Sending the Letter

Once reviewed and approved by the legal team, the SAR Extension letter is sent to Sarah via registered mail and email, ensuring proof of receipt. David also keeps a copy of the letter and its delivery confirmation for the company's records.
