Consumer testing of communications — mandatory rule or guidance recommendation?

RLB-F-GB-FCA-CONSUMER-DUTY-PS22-9-Q007
What the RLB Specialist Panel found

4. Consumer testing of communications — mandatory rule or guidance recommendation?

  • Question (paraphrased to protect IP): Is consumer testing of communications a mandatory requirement under the Consumer Duty? What does PRIN 2A.5 require versus what FG22/5 recommends on this point?
  • Source regulation: Consumer Duty (PS22/9 + PRIN 2A), Financial Conduct Authority (Regulator portal: https://www.fca.org.uk)
  • What AI assistants typically say: AI tools acknowledge that consumer testing is not an absolute mandatory requirement, but then assert that PRIN 2A.5.10R — a specific binding rule marked "R" in the FCA Handbook — requires firms to test the effectiveness of their communications "where appropriate."
  • What the regulator actually says: FG22/5 contains guidance (not rules) recommending firms "should" consider consumer testing of communications. PRIN 2A.5 requires firms to act to deliver good consumer understanding as an outcome, but prescribes no specific methodology for achieving it.
  • Why the AI went wrong: The AI misattributed the consumer testing methodology from FG22/5 guidance to a specific binding rule reference (PRIN 2A.5.10R), directly contradicting the distinction between guidance and rules that the question specifically concerns. This is a material error: whether a requirement sits in a rule or in guidance has significant implications for enforcement and the adviser's compliance obligations.

Impact for this audience

If a Financial Adviser treats consumer testing as a binding rule requirement based on the AI's misattribution to PRIN 2A.5.10R, they will design their communications review process around an obligation that does not exist as framed. More significantly, if they advise a client firm that consumer testing is a mandatory rule requirement and a regulator subsequently finds otherwise, the adviser's recommendation will be exposed as unsupported. Conversely, a firm that is told consumer testing is optional because the adviser did not understand the guidance/rule distinction may underinvest in a practice the FCA's own guidance actively recommends — neither outcome serves the client.
