The UK’s online Safety Act: A New Era of Digital Regulation

On 25 July 2025, the internet in the UK changed. Not visually, but legally. The first major enforcement phase of the Online Safety Act has now kicked in, with sweeping implications for how we browse, post, and access online content.
This legislation, originally passed in October 2023, places new responsibilities on tech companies to protect users — especially children — from harmful material. While some hail it as a long-overdue safeguard, others warn it could threaten privacy, freedom of expression, and access to information.
So what exactly is changing — and why is the UK suddenly at the forefront of internet regulation?
1. What Is the Online Safety Act?
The Online Safety Act 2023 is one of the most ambitious attempts by a Western democracy to regulate the internet. Its aim is to make online spaces safer by placing a statutory duty of care on digital platforms. In practice, this means services like social media, forums, search engines, and adult sites must actively assess and reduce the risk of users — especially under-18s — encountering illegal or harmful content.
Enforcement falls to Ofcom, the UK’s communications regulator, now equipped with sweeping powers. It can fine companies up to £18 million or 10% of global turnover, block access to services in the UK, or pursue criminal charges against executives in serious cases.
2. What Just Came Into Force?
Though the Act passed in 2023, it’s being rolled out in phases. The most visible phase began on 25 July 2025, focusing on two key areas: pornography age verification and child protection on major platforms.
2.1 Age Verification for Pornographic Content
Websites hosting pornographic or “high-risk adult” material must now verify users’ ages before granting access. Gone are the days of tickboxes or casual “Are you over 18?” prompts. Platforms must now use “highly effective” age checks — such as ID uploads, facial age estimation, mobile provider validation, or third-party verification tools.
Sites that don’t comply face large fines or may be blocked from UK access entirely. Some have already restricted UK users to avoid liability.
This shift brings the UK’s pornography laws in line with gambling sites and makes the country one of the most tightly regulated for adult content.
2.2 Protecting Children from Harmful Content
Social media platforms and search engines — like YouTube, TikTok, Instagram, Reddit, Google, and X (formerly Twitter) — must now take proactive steps to protect children from harmful content.
Under Ofcom’s Children’s Codes, platforms must prevent minors from encountering material related to self-harm, suicide, eating disorders, sexual violence, and other high-risk topics. This includes not only visible content, but also algorithmic recommendations and search results. Companies must publish risk assessments and make it easier to report harmful posts.
The shift is clear: platforms must now actively prevent exposure, not just respond when problems arise.
2.3 What Happens If Platforms Don’t Comply?
Platforms that fail to meet their legal duties risk major consequences. Ofcom can issue fines, block services, or even pursue criminal prosecutions for serious breaches.
This applies to any site used by UK users, no matter where it’s based. Some smaller services have already chosen to block UK visitors rather than attempt full compliance.

3. What’s the Opposition?
Not everyone supports the Act. Critics argue that it introduces major risks to privacy, free speech, and access to information.
3.1 Privacy Concerns
Requiring users to upload IDs or submit to facial scans raises serious privacy questions. Critics fear these checks could lead to data breaches, misuse by third parties, or a chilling effect on communities that rely on online anonymity—such as LGBTQ+ users or survivors of abuse.
For people accessing LGBTQ+ support, sexual health advice, or mental health services, these checks could deter them from seeking help online.
3.2 Questionable Effectiveness
While the rules aim to protect children, many argue they’ll be easy to circumvent. Hackers have already shown that some age-verification systems can be bypassed in seconds. VPNs, alternative platforms, and offshore sites remain accessible.
Critics warn the law might create a false sense of safety while failing to stop determined users from accessing harmful material.
3.3 Free Expression and Public Knowledge
There’s growing concern that the Act could lead to over-censorship, as platforms try to avoid penalties by removing anything that might seem harmful. In the process, they may suppress legitimate and educational content — especially around sex education.
Posts about contraception, STI prevention, or queer identity could be wrongly flagged as “adult” content, particularly by automated systems. That risks cutting off vital information, especially for young people who rely on the internet when offline sources aren’t accessible or safe.
Support forums and mental health communities also face uncertainty. Users often access these spaces anonymously, and the fear of identity checks or takedowns may discourage them from speaking up.
Even Wikipedia has taken legal action, warning that treating it like a commercial platform could force age checks or editing limits — threatening its mission to offer free, public knowledge to all.
Enforcement also presents a major headache. Platforms like X face particular scrutiny — internal estimates suggest around 13% of tweets contain pornographic content. The company says it will estimate age via email patterns and contact lists, but regulators remain sceptical of how reliable or transparent that system really is.

4. What are other countries doing?
Many other countries are heading in similar directions.
France recently introduced ID-based age checks on adult sites, prompting some platforms to block access in protest. Germany has long required age restrictions on explicit content, though enforcement is patchy. Australia is trialling facial age estimation, and a few US states, like Utah and Louisiana, have passed similar laws — but many face legal challenges. Of course China has the worlds most controlled internet where access requires a identity number and they use this personal information to take control all forms of access.
5. What Lies Ahead?
Ofcom will monitor platform compliance over the coming months. Enforcement actions are likely to begin in earnest from late 2025. Meanwhile, major companies like Meta are developing new methods — such as AI-based behavioural modelling — to meet age-check standards without collecting sensitive personal data.
Legal challenges will continue. Wikipedia’s case, heard in July, could set an important precedent. Further battles may come over encrypted messaging platforms and algorithm transparency.
As more countries explore similar legislation, the UK’s next moves may shape not just domestic internet use, but also how global platforms choose to operate across borders.

7. In Conclusion
The Online Safety Act marks a turning point in how online spaces are governed. Supporters argue it will finally hold tech giants accountable and help protect vulnerable users — especially children — from real harm.
But it also brings big questions. Will it protect, or overreach? Can platforms comply without over-censoring? Can privacy survive the age-checked web?
Whatever the outcome, the UK’s bold experiment in online regulation has begun — and whether it becomes a model or a cautionary tale, the world is paying attention.
