COBS 4 is the section of the FCA's Conduct of Business Sourcebook that governs financial promotions. It applies to every FCA-authorised firm and sets the standard that all marketing communications about regulated financial products must meet.
The core requirement is straightforward: every financial promotion must be fair, clear and not misleading. That means balanced presentation of benefits and risks, unambiguous language the target audience can understand, and no false or deceptive claims. This applies across emails, landing pages, social media and every other marketing channel.
In practice, COBS 4 compliance calls for pre-approval workflows so promotions are reviewed before publication, content scanning to catch trigger terms and missing disclosures, and complete audit trails that show supervisory oversight. Firms relying on manual review alone are finding it harder to keep pace as the FCA ramps up enforcement.
