UK Enforces Online Safety Act: Age Checks Started

Apps, search engines, and adult sites must now stop minors from viewing harmful content.

From 25th of July 2025, the UK’s Online Safety Act became reality. Ofcom can fine any service up to £18 million or 10 % of global turnover if it fails to protect children from pornography, self‑harm, or suicide content. Parents in Sevenoaks will notice new pop‑ups, ID checks, and face‑scan prompts on popular apps.

From now on, any website or service that displays adult or otherwise harmful material must ensure that no one under 18 can access it. This requirement goes far beyond traditional adult sites—it includes social media apps, search engines, cloud-gaming platforms and even virtual-reality worlds. Ofcom will carry out compliance audits on all these services through 30 September 2025, after which it will take enforcement action against any that fall short.

“There has been a rush from services to get stuff in this week, and we need to see if it works.” — Oliver Griffiths, Ofcom group director for online safety.

Failure to comply risks eye‑watering fines and, in repeat cases, UK blocking orders.

How will platforms check age?

To verify UK users’ ages, platforms will adopt a suite of “highly effective” methods recommended by Ofcom. Some services will ask for a government-issued photo ID and check it against secure databases, while others deploy AI-powered “face-age” estimation from a simple selfie. Financial verification—linking a credit or debit card or bank account—offers another robust proof of adulthood, and more streamlined options like mobile-billing authentication or a confirmed email address can also suffice. Crucially, providers only receive a yes/no confirmation of age, so no extra personal data is stored or shared.

  • Photo‑ID scans matched to government databases.
  • Face‑age AI that estimates age from a selfie.
  • Credit‑card or bank checks that confirm an adult account.
  • Mobile‑billing or e‑mail links tied to verified adult details.

Ofcom lists these methods as “highly effective” and stresses privacy; sites receive only a yes/no age token.

Who has moved first?

X (formerly Twitter) now locks all “Sensitive Media” behind an ID check, and TikTok has rolled out AI-driven age-estimation prompts for its UK audience. Reddit requires instant age verification before granting access to any r/18+ community, and major adult sites—Pornhub, YouPorn, and RedTube—introduced government-approved age-assurance systems just this week.

What this means for Sevenoaks families

Although the Act is national, its impact is local. Teens now notice that certain subreddits and TikTok clips simply vanish. Platforms tighten rules and push adult material out of sight, so young users meet new digital walls every day.

Therefore, parents must still lock down devices at home. Clear‑headed guidance and strong settings keep teens on safer paths. Otherwise, tech‑savvy kids fire up a VPN, hop across borders online, and skirt every filter. A VPN, or Virtual Private Network, routes traffic through far‑off servers and masks real locations. As a result, school blocks and age gates crumble, and forbidden sites pop back into view.

Consequently, schools should update every online‑safety lesson. Show pupils how age checks work, why they matter, and how VPN tricks undo them. Arm students with facts, not fear, and remind them that privacy tools demand responsibility.

  • Teens may find certain sub‑reddits or TikTok videos suddenly invisible.
  • Parents must still enable device‑level controls; determined teens can use VPNs.
  • Schools will update online‑safety lessons to include age‑verification reality checks.

Quick tips for parents

  1. Talk early: explain why some content is off‑limits.
  2. Switch on app‑store age limits and family‑link tools.
  3. Keep devices in shared spaces; stay curious about your child’s screen time.
  4. If you spot breaches, report them to Ofcom via the Report Harmful Content portal.

Implications for local businesses

  • Businesses hosting user-generated or age-restricted content (e.g. forums, video platforms) must implement age assurance solutions compliant with Ofcom guidelines.
  • E-commerce platforms selling adult or self-help products need mandatory age gates at key interaction points (e.g. checkout, account creation).
  • Digital agencies and web developers should audit client sites for compliance, integrating age-check APIs or ID-scan modules.
  • Hospitality and entertainment venues offering online booking or promotions must verify age before granting access to adult events or services.
  • Businesses must update privacy policies and terms of service to disclose new data-handling practices under age verification protocols.
  • Companies can partner with specialised age assurance tech providers to streamline implementation and ensure regulatory compliance.
