Inside Meta's High Court Battle Over UK Online Safety Fees: 8 Key Facts

Introduction

In a move that pits one of the world's largest tech companies against the UK's communications regulator, Meta has filed a judicial review challenging how Ofcom calculates fees under the Online Safety Act. The dispute, heard at the High Court in early April 2025, centers on the methodology used to determine charges for compliance with the landmark legislation. With the first invoices set to arrive in September 2025, Meta is pushing for a change before payments become due. Here's everything you need to know about this high-stakes legal fight.

1. What Is the UK's Online Safety Act?

The Online Safety Act, passed in 2023, is a sweeping piece of legislation designed to make the UK the safest place in the world to be online. It imposes a duty of care on platforms to protect users from illegal content and to safeguard children from harmful material. Ofcom, the UK's communications regulator, is responsible for enforcing the act, including setting and collecting fees from tech companies to cover its regulatory costs. The act applies to any platform that hosts user-generated content, from social media giants like Meta's Facebook and Instagram to smaller forums.

2. How Ofcom Calculates Fees Under the Act

Ofcom's fee structure is based on a tiered system that considers a platform's global revenue and its user base within the UK. The larger the company, the higher the fee. The regulator also takes into account the risk level of the services provided. Under the current methodology, fees are calculated using a formula that weights revenue and user numbers, with adjustments for categories like 'categorised services' (those with high reach or certain functionalities). Meta argues that this approach is disproportionate and lacks transparency, leading to an unfairly high bill for its UK operations.

3. Meta's Judicial Review Challenge

Meta has taken Ofcom to the High Court, seeking a judicial review of the fee calculation method. Judicial review is a legal procedure that examines the lawfulness of a public body's decision. Meta claims that Ofcom's methodology breaches the principles of the act itself, which requires fees to be 'proportionate' and 'objectively justified.' The company argues that the current formula overstates its UK-related costs and fails to reflect the actual regulatory burden. Meta is asking the court to quash the fee schedule and order Ofcom to recalculate it using a revised approach.

4. The Timing Is Crucial

The first invoices from Ofcom are expected to be sent out in September 2025. Meta has made it clear that it wants the basis of those charges changed before they land. The company's legal challenge was filed in early April, giving the court potentially months to rule before the deadline. If the court decides in Meta's favor, it could delay the invoicing process or force Ofcom to redesign its fee structure. Conversely, if Ofcom wins, Meta will likely have to pay the disputed amount and may consider an appeal.

5. Potential Impact on Other Tech Companies

While Meta is the first major platform to challenge Ofcom's fees, it may not be the last. Many large tech firms, including Google, Amazon, and TikTok, are also subject to the Online Safety Act and could face similar bills. A successful judicial review by Meta could set a precedent, encouraging others to contest their fees or seek adjustments. On the other hand, if Ofcom's methodology is upheld, it could lead to a wave of compliance payments from the tech sector, affecting budgets and operations in the UK.

6. Ofcom's Position and Response

Ofcom has defended its fee calculation, stating that it was developed after extensive consultation with industry stakeholders and that it complies with the requirements of the Online Safety Act. The regulator argues that the fees are necessary to fund its enforcement activities, which include monitoring, investigations, and issuing penalties for non-compliance. In court documents, Ofcom has described Meta's challenge as 'premature' and without merit, noting that the fee structure was published in draft form for comment before finalization. The regulator is represented by leading counsel and is expected to vigorously defend its methodology.

7. What a Judicial Review Means in Practice

A judicial review is not an appeal on the merits of the decision but a check on whether the public body acted within its legal powers and followed proper procedures. The High Court will examine whether Ofcom's fee calculation was 'irrational,' 'procedurally unfair,' or 'ultra vires' (beyond its legal authority). The court can quash the decision, require Ofcom to reconsider, or uphold it. The process typically takes months, with hearings, written submissions, and a final judgment. In this case, the outcome could have broad implications for how regulatory fees are set under the act.

8. Next Steps in the Dispute

The High Court hearing in early April was a preliminary stage where both sides presented their arguments. A full hearing is expected later in 2025, likely before September. If the court rules against Ofcom, the regulator will have to revise its fee schedule, potentially delaying invoice issuance. Meta may also seek an interim order to suspend the invoicing pending the outcome. Meanwhile, industry observers are watching closely, as the case could shape the financial landscape of UK online regulation for years to come. Both parties have indicated a willingness to settle, but no talks have been confirmed.

Conclusion

Meta's judicial review against Ofcom over Online Safety Act fees highlights a growing tension between tech giants and regulators. The outcome will not only determine how much Meta pays but could also influence the broader approach to funding internet safety enforcement. As the September deadline approaches, all eyes are on the High Court to see whether the fee formula stands or must be rewritten. One thing is certain: this battle is far from over.
