On August 9, 2023, the UK’s Information Commissioner’s Office (ICO) and Competition and Markets Authority (CMA) released a joint position paper (the Paper) focused on “harmful” website design practices that may “trick” consumers into giving more access to their personal information. The Paper is targeted at web designers and developers, and it will be particularly relevant to consumer-facing organizations that target the UK market. It builds on joint work that the ICO and CMA have been engaged in since May 2021, when the regulators issued a joint statement promising a “joined up approach to regulation.” Announcing the Paper’s release, the ICO also revealed that it will be assessing cookie banners of the most frequently used websites in the UK, with a view to taking action against harmful designs.
