Two common mistakes when relying on consent under the GDPR

Consent is one of six lawful bases for processing personal data under the General Data Protection Regulation (GDPR). However, GDPR consent may only be used where it is genuinely freely given, informed and can be withdrawn; otherwise, the processing is unlawful. Despite this, consent under GDPR is often used by default without regard to the strict conditions that apply. Below are two frequent pitfalls to avoid.

1. Consent is used where it is not freely given

Where there is a dependency or imbalance of power, for example between an employer and an employee, the voluntariness of consent is doubtful. In such cases, another lawful basis for processing personal data under the GDPR should be considered, such as contract or legitimate interests. Always ask whether the data subject truly has a free choice, or whether the situation means they effectively have only one option. This is essential to ensure informed consent under the GDPR and to preserve the lawfulness of processing.

2. Consent cannot be evidenced or withdrawn

Many organisations lack documentation proving that consent was validly obtained. The GDPR requires that consent is traceable and that withdrawal of consent is as easy as giving it. A tick-box alone is insufficient: the organisation must be able to demonstrate when, how and for which purpose consent was captured. In practice, maintaining a GDPR consent log is prudent, covering the consent record, the notice shown, and the purpose. Clear procedures are also needed to manage the full life cycle of consents, including the data subject’s right to withdraw consent and the operational steps to effect swift withdrawal.

At Morling Consulting, our GDPR lawyers help organisations assess when consent is the right lawful basis and ensure it meets the Regulation’s requirements. We review not only forms and copy, but entire consent processes—from collection through to potential revocation—so that GDPR consent is evidenced, auditable and aligned with compliance by design.

Related considerations often include employee consent under the GDPR (where reliance is usually inappropriate due to imbalance), documenting informed consent under the GDPR, and aligning records of processing with your consent framework to support the overall lawfulness of processing.

If you need support establishing a robust GDPR consent log, evidencing consent, or operationalising the right to withdraw consent, our team can assist with design, implementation and governance.
