The United Kingdom’s communications regulator has launched an investigation into Telegram over concerns that the platform may be failing to prevent the spread of illegal content related to child sexual abuse and online grooming.
The probe, led by Ofcom, follows evidence from the Canadian Centre for Child Protection indicating that such material may be circulating on the messaging service. Regulators stated they will assess whether Telegram has breached its obligations under the UK’s Online Safety Act, which requires platforms to limit the distribution of illegal content and protect users, particularly minors.
The investigation also extends to two additional chat platforms, Teen Chat and Chat Avenue, which are being examined for potential risks of grooming. Ofcom stated that earlier engagement with these services did not provide sufficient assurance that they were adequately protecting children from harm.
Under the Online Safety Act, companies that host user-generated content must implement systems to assess and mitigate risks related to illegal activity. Regulators said they will review whether Telegram has appropriate safeguards in place to detect and remove harmful material, including child sexual abuse content.
If violations are identified, Ofcom has the authority to impose financial penalties. The regulator stated that fines could reach up to £18 million or 10% of a company’s global revenue, depending on the severity of the breach.
The investigation is part of a broader enforcement activity targeting online services that allow user interaction, including messaging platforms and chat sites. Regulators are focusing on whether these services are taking adequate steps to prevent misuse, particularly in cases involving the exploitation and grooming of minors.
Telegram has denied the allegations, stating that it has implemented detection systems and worked with external organisations to reduce the spread of illegal content. The company said it was “surprised” by the investigation and questioned the basis of the claims, according to reporting.
Ofcom stated that the investigation process will involve gathering evidence and determining whether a breach of legal duties has occurred. If preliminary findings indicate non-compliance, the company will be given an opportunity to respond before a final decision is made.
The regulator has not provided a timeline for the conclusion of the inquiry. No final determination has been made regarding potential penalties or enforcement actions.
