The Online Safety Act
The UK’s online safety regime has moved from preparation to enforcement. We are in the room for both.
Cooley has advised dozens of technology companies on the UK Online Safety Act (OSA) – from the largest categorised services to the fast-scaling businesses that will define the next decade. We help clients build compliance programmes that survive scrutiny, and we defend them when that scrutiny arrives.
Why Cooley
-
We act for the companies the regime was written about.
Depth across the world’s largest platforms means we know how Ofcom approaches these issues in practice, not only how the codes read on the page.
-
We are technology lawyers first.
Our clients build the products under scrutiny. We understand recommender systems, moderation pipelines, age assurance stacks and generative AI features well enough to give advice that engineering teams can actually implement.
-
Compliance and defence in one team.
The lawyers who help design a compliance programme are the ones who defend it. That continuity matters when a regulator asks why a decision was made two years ago.
-
One regime among many.
Sitting within Cooley’s European tech regulation practice, we advise on the OSA alongside the EU Digital Services Act (DSA), General Data Protection Regulation (GDPR), AI Act and consumer protection law – so clients get a coherent strategy rather than parallel and sometimes contradictory advice.
Our experience
That work spans:
- The full range of duties – illegal content, children’s safety and age assurance, and categorised service obligations, including for services designated in Ofcom’s register.
- Multiple regulatory engagements with Ofcom, including responses to statutory information requests and supervisory correspondence.
- Active investigations, where we act for providers under formal Ofcom scrutiny.
- Judicial review, where we have been instructed on public law challenges connected to the regime.
- The full spectrum of clients – from global platforms with tens of millions of UK users to venture-backed companies encountering their first substantive regulatory obligation.
We are also advising on what comes next: the government’s proposals for further online safety measures, the additional duties consultations now open, and the interaction between the OSA and DSA, the AI Act, and equivalent regimes emerging in other markets.
