Harm prevention under the Consumer Duty — the customer-acceptance defence

RLB-F-GB-FCA-CONSUMER-DUTY-PS22-9-Q003
What the RLB Specialist Panel found

2. Harm prevention under the Consumer Duty — the customer-acceptance defence

  • Question (paraphrased to protect IP): Does the Consumer Duty require firms to prevent all foreseeable harm to retail customers? What is the position where a customer understands and accepts a risk?
  • Source regulation: Consumer Duty (PS22/9 + PRIN 2A), Financial Conduct Authority (Regulator portal: https://www.fca.org.uk)
  • What AI assistants typically say: AI assistants describe a position in which a firm avoids breach when a customer accepts a risk, provided the firm has acted in good faith, supported the customer's understanding, and avoided harm caused by its own conduct. The AI frames this as a multi-condition test before the customer's acceptance becomes relevant.
  • What the regulator actually says: The FCA rule provides: "Where a firm reasonably believes a retail customer understands and accepts such risks, it will not breach the rule if it fails to prevent them." The operative trigger is the firm's reasonable belief — not an objective test of the customer's actual understanding, and not contingent on additional conditions.
  • Why the AI went wrong: The AI dropped the "reasonably believes" qualifier — which is the element that defines the firm's standard of assessment — and replaced it with three additional conditions that do not appear in this specific rule. The result is a more burdensome and legally inaccurate formulation that would cause a Compliance team to over-engineer its processes relative to what the rule actually requires.

Impact for this audience

A Compliance team that accepts the AI's multi-condition formulation of the customer-acceptance defence will build a more burdensome internal policy than the rule requires — requiring staff to demonstrate good faith, supported understanding, and the absence of own-conduct harm before treating customer risk-acceptance as relevant. This over-engineering wastes resource and creates an audit trail that may be read by the FCA as evidence the firm believed these conditions were legally required. Conversely, if the AI's version were applied as a lighter standard than intended, a firm might incorrectly conclude it has a defence when the 'reasonably believes' threshold has not actually been met. Either error carries the risk of FCA challenge in a supervisory review or enforcement context.
