TL;DR: Ofcom published draft rules in July 2026 for a fraudulent advertising code under the Online Safety Act, with 40 proposed measures for platforms like Facebook, Google and YouTube: banning scam advertisers, verifying who sets up ad accounts, requiring banking and investment advertisers to be FCA-authorised, testing AI ad tools and fast-tracking police reports. Fines could reach £18m or 10% of global revenue. The consultation closed on October 2; final rules are expected next year, so protection won’t arrive until 2027 at the earliest.

Why this matters

UK Finance says 66% of bank transfer fraud in 2025 started online, and investment fraud cases rose 26%, as Which? reported. Fake celebrity investment ads, copycat retailer ads and fake “apps” in sponsored posts are a big part of that.

The proposed measures

Among Ofcom’s 40 draft measures:

The teeth

Firms that fail to comply could face fines of up to £18m or 10% of global revenue, whichever is greater. Meta is challenging the proposed fines in court, Which? reports.

Timeline

Which?’s Rocio Concha called the proposals “a significant step” towards holding firms accountable.

Until then: protect yourself
