The UK government is introducing enhanced Ofcom oversight for major video-on-demand platforms with more than 500,000 UK users, designating them as 'Tier 1' services subject to new standards on accuracy, impartiality, and protection from harmful content. A new accessibility code aligned with broadcast rules will require mainstream streaming services, including public service platforms like ITVX and Channel 4, to subtitle at least 80% of their catalogues, provide audio description for 10%, and signing for 5%. These measures implement the Media Act 2024 and aim to create a more level regulatory playing field between traditional broadcasters and on-demand services.
