Should financial advisers use WhatsApp for lead follow-up?

WhatsApp is a legitimate follow-up channel for UK financial advisers provided the firm treats it as a regulated communication and records it accordingly. The FCA has no blanket prohibition, but it does require that any business communication on a personal or shared device be captured, reviewed and retained under SYSC 10A and the wider communications recording regime.

For inbound WhatsApp leads, response speed materially improves conversion. Platinum Prospects campaign data shows WhatsApp-led follow-up conversion running 35 to 55 per cent higher than email-only follow-up for the same lead source, because the prospect is responding on the channel they chose. The trade-off is operational: advisers must use a compliant solution such as WhatsApp Business API via an approved vendor (Smarsh, CellTrust, Global Relay, MirrorWeb or similar) that captures every message server-side, rather than WhatsApp Business consumer on a personal phone.

Consent is a further consideration. The Privacy and Electronic Communications Regulations (PECR) require that marketing messages to consumers have opt-in consent; operational follow-up to an already-submitted inbound enquiry is treated differently and sits within legitimate interest, but firms should document this in their privacy notice and lead-capture flow.

Practical guardrails: use one firm-owned number per adviser, never personal mobiles; add an explicit "we will contact you by WhatsApp" checkbox on the lead form; log every conversation into the CRM so suitability evidence is preserved; and require compliance review of any templated outbound message just as you would for email.
