Meta appeals Ofcom’s Category 1 designation of WhatsApp and Instagram

Meta has filed an appeal against Ofcom's decision to categorise WhatsApp and Instagram as Category 1 services under the UK Online Safety Act, the tier that carries the heaviest compliance duties. This is a challenge to how the regulator classified the services, not an appeal against any finding that Meta broke the law. No breach ruling against Meta exists.

It is the second action META has brought against Ofcom this year. In May the company sought judicial review of the regulator's revenue-based methodology for calculating fees and penalties. The two cases are separate: one contests how the services are classified, the other how the regulator sizes its charges. Ofcom's Oliver Griffiths has publicly acknowledged the two actions and described the environment as highly litigious.

Category 1 designation is what Meta is trying to shed, and it is a meaningful compliance step up. It brings transparency reporting obligations, a requirement to offer user-empowerment tools, duties around fraudulent advertising, and record keeping on illegal content. The Act's penalty ceiling is 10% of qualifying worldwide revenue or 18 million pounds, whichever is higher, which is what makes the classification worth litigating rather than absorbing.

Figures circulating for what that ceiling would mean in Meta's case vary between sources and conflict with one another, so we are not putting a dollar amount on it here. The percentage cap is the sourced fact; the implied fine is not.

The outcome sets a reference point for how the Category 1 threshold gets applied to messaging services specifically, where encryption makes several of the duties harder to satisfy. That is the part other platforms will be reading closely. META closed Friday at $665.75, down 2.4% on the session, though nothing in the reporting attributes that move to this filing.
