Is cookie consent required for a WordPress site?

Not simply because the website uses WordPress. Cookie consent is required only when the site uses cookies or similar technologies that need consent under the privacy rules that apply to its visitors.

WordPress itself can use cookies for functions such as authentication and comments, while plugins, analytics tools, advertising platforms, embedded content, and e-commerce features may introduce additional trackers.

If those technologies require consent, they should be managed through an appropriate cookie consent plugin setup before they are activated. A Cookie Checker can help identify cookies and trackers added by themes, plugins, and third-party services.

In short, the requirement depends on what the website actually uses, not on WordPress itself.
