Does a Custom Cookie Banner Comply with GDPR?

A custom cookie banner can meet GDPR and applicable cookie requirements. The law does not generally require a particular provider or a paid consent platform. The Irish DPC confirms that using a third-party CMP is optional.

Your custom implementation must provide clear information, obtain valid permission before relevant tracking, honour rejection, record consent and make withdrawal easy.

The practical challenge is maintaining those controls as scripts, plugins and services change. You must also ensure consent-dependent tracking remains inactive if your banner fails to load. A custom design can comply, but functioning consent controls are essential to meeting cookie banner requirements.
