The short version

Key takeaways

The unit of client management is the household, not the individual. CRMs that only model contacts are a decade behind.
Vulnerability assessment is continuous, not a checkbox. The CRM should prompt for re-assessment at defined moments.
Lifetime value is measured across remortgage cycles and protection renewals, not single transactions.

The household model

A mortgage application is household-level: two applicants, joint income, joint liabilities. A CRM that forces you to manage each applicant as a separate contact generates duplicate work and suitability gaps. Model the household as the primary entity; individuals are members.

Vulnerability at the record level

Under FG21/1, firms must embed vulnerability into every stage of the customer journey. At the record level this means: four-driver assessment (health, life event, resilience, capability) captured at fact-find, re-prompted at recommendation, and re-evaluated at any life-event trigger.

Communication record

Every outbound communication is a regulatory artefact. Capture the channel, the content, who sent it, who approved it (if automated), and any client response. Under Consumer Duty, firms must evidence that communications support understanding.

Record retention

MCOB 4 requires suitability records for a minimum of three years; in practice firms should retain for the life of the relationship plus six. Your CRM must meet this without manual export. Retention must be defensible to the ICO under UK GDPR's storage-limitation principle.

Lifetime value across cycles

A well-managed client returns at remortgage (every 2-5 years), upsizes for protection, and refers. The CRM should prompt each of these touchpoints automatically — not sit silent between cases.
