Essential Legal Mandates
Online Safety Act 2023 (Ofcom)
Ofcom now holds platforms (Meta, TikTok, X) legally responsible for preventing the spread of 'harmful content'.
ASA CAP Code & Social Responsibility
The primary rulebook for UK advertising. Beyond truthfulness, it mandates 'Social Responsibility'.
Strategy Adaptation for United Kingdom
TikTok Standards
"A high-priority target for Ofcom. TikTok's UK algorithm is highly sensitive to 'Harmful Claims'."
Meta Standards
"Adheres to strict ASA standards regarding 'Personal Attributes'."
Navigating UK Advertising Compliance Across Platforms
The UK's Online Safety Act gives Ofcom enforcement powers that directly affect how platforms moderate advertising content. TikTok is under particular scrutiny — advertisers should cross-reference TikTok's community guidelines with ASA rulings, as the UK algorithm is tuned for aggressive harmful claims detection. For Meta campaigns, the ASA's Social Responsibility requirements add a layer beyond Meta's standard ad policies.
Google Ads in the UK require mandatory G2 verification for financial products — unverified ads are outright prohibited. Review the Google Ads policy guide for verification steps. Financial services advertisers must include FCA-style risk warnings, and gambling brands face some of the strictest ad restrictions globally under the ASA CAP Code.
The UK's approach shares similarities with both the EU's DSA framework and US FTC endorsement requirements, though enforcement mechanisms differ significantly.
