Meta has initiated legal action against the UK communications regulator Ofcom over the implementation of the Online Safety Act, joining a growing group of companies challenging the watchdog’s regulatory framework, according to reporting by The Guardian on September 20, 2026. The dispute centers primarily on Ofcom’s classification of WhatsApp and Instagram as Category 1 services, which imposes strict transparency, accountability, and safety mandates on the platforms.
WhatsApp and Instagram Category 1 Classification Dispute
According to Irish Legal News on September 21, 2026, the core of Meta’s legal challenge targets Ofcom’s decision to designate WhatsApp and Instagram under Category 1 of the Online Safety Act. This designation triggers heavy regulatory duties, including enhanced user controls, aggressive measures to detect fraudulent advertising, and rigorous systems for recording and reporting illegal content, as reported by News18. Meta argues that these specific mandates are built for large public platforms and fail to fit private messaging environments and small group chats on WhatsApp, according to CIJ World. A Meta spokesperson stated that the company is challenging certain implementation aspects alongside other industry players—including TikTok, Roblox, X, and Quora—while emphasizing that Meta does not oppose the legislation itself, but rather Ofcom’s interpretation to ensure proportionate enforcement, as detailed by Eastern Eye. Ofcom’s Category 1 register captures platforms including Facebook, Instagram, WhatsApp, YouTube, TikTok, X, Reddit, Snapchat, Pinterest, Roblox, and Quora, according to CIJ World. Regulatory thresholds for this classification require more than 34 million monthly UK users combined with a recommendation system, or over 7 million UK users accompanied by recommendation tools and sharing functions, according to MediaNama. Roblox and Quora have also filed appeals against their classifications, while TikTok and X launched separate legal actions regarding the volume of information Ofcom demands they supply, according to Irish Legal News and CIJ World.
High Court Challenges Over Regulatory Fees
This court filing compounds an existing legal battle between Meta and the UK regulator. Meta previously filed a lawsuit against Ofcom in the High Court in London regarding the fee structure designed to fund the regulator’s online safety operations, according to Irish Legal News and Lavx.hu. Meta argued in court filings that Ofcom’s fee methodology is fundamentally flawed because it relies on global revenues rather than localized metrics. The High Court scheduled the main hearing for this fee dispute on October 13 and 14, 2026, according to Lavx.hu. During Ofcom’s initial consultations, Meta proposed establishing a lower turnover threshold of 65 million to 100 million British pounds—instead of Ofcom’s proposed 250 million pounds—alongside a separate entry point based on 3 million monthly active UK users and a cap on qualifying global revenue contributions, as reported by Lavx.hu. Under the current enforcement powers of the Online Safety Act, Ofcom holds the authority to penalize severe non-compliance with fines reaching up to 10 percent of a company’s qualifying worldwide revenue or 18 million British pounds, whichever sum is greater, according to Lavx.hu.
Political Reactions and Parliamentary Scrutiny
The legal challenges have triggered sharp debate across the UK political landscape. Former junior minister for technology and the digital economy Damian Collins characterized Meta’s courtroom strategy as a deliberate effort to stall and frustrate the implementation of the Online Safety Act, describing the tactic as “lawfare” designed to bog down the regulator, according to IndiaTimes. Conversely, Culture Secretary Lisa Nandy criticized Ofcom’s enforcement pace as exceedingly slow, pressing the regulator to adopt a much more robust and rapid posture, as reported by IndiaTimes. Addressing these criticisms before a House of Lords committee in September 2026, Ofcom group director for online safety Oliver Griffiths acknowledged that the agency faces an overwhelming workload while operating in an intensely litigious environment, according to IndiaTimes. A House of Lords committee continues to examine the overall efficacy and rollout of the legislation, while Ofcom’s public consultation regarding broader Category 1 obligations closes on October 2, according to CIJ World and Eastern Eye.
