Online platforms operating in the United Kingdom will be legally required to proactively block scam advertisements under new enforcement guidelines from Ofcom, the country's communications regulator. The move, announced on Friday, marks a significant escalation in the fight against online fraud, which cost British consumers an estimated £1.2 billion in 2025 alone.
New Duties Under the Online Safety Act
The rules, set to come into effect in early 2027, are part of the UK's Online Safety Act, which was passed in 2023. Ofcom will mandate that platforms such as Meta, Google, and X implement systems to detect and remove scam ads before they reach users. Previously, platforms were only required to respond to reports of fraudulent content. Now, they must take a more proactive stance, using automated tools and human moderators to identify scams.
According to Ofcom, the new regulations will cover all paid-for advertisements, including those promoting fake investments, counterfeit goods, and phishing schemes. Platforms that fail to comply could face fines of up to 10% of their global annual turnover, a penalty mirroring the maximum sanctions under the Act.
Scope of the Problem
Scam ads have become a pervasive issue on social media and search engines. A 2025 report by the UK's Financial Conduct Authority found that 40% of adults had encountered a scam ad online, with losses averaging £1,200 per victim. The new Ofcom rules aim to close the gap that allowed fraudsters to exploit advertising systems.
“Fraud is not a victimless crime; it destroys lives and livelihoods,” said Dame Melanie Dawes, Ofcom’s chief executive. “These new duties will force platforms to take responsibility for the ads they host, rather than leaving it to users to report suspicious content.”
Industry Reaction
Tech companies have expressed mixed reactions. A spokesperson for Google said the company supports efforts to combat scams but warned that overly aggressive filtering could inadvertently block legitimate ads. “We are committed to working with Ofcom to refine these rules,” the spokesperson said. Meanwhile, Meta stated that it has already invested heavily in AI tools to detect fraudulent ads, but acknowledged that more work is needed.
Consumer advocacy groups have welcomed the move. “For too long, platforms have profited from scam ads while victims bear the cost,” said Rocio Concha, director of policy at Which?. “This is a crucial step toward making the online world safer for everyone.”
Implementation Timeline
Ofcom will consult on the detailed codes of practice over the next six months, with final rules expected by mid-2027. Platforms will then have a further six months to comply. The regulator has indicated that it will begin enforcement actions against non-compliant companies from 2028.
The UK is among the first countries to impose such a proactive duty on platforms, setting a precedent that could influence regulators in Australia and the European Union. Australia's eSafety Commissioner has already signaled interest in similar measures.
