Which FCA principle requires paying due regard to customer interests and treating them fairly?

• A. Pay due regard to customer interests and treat them fairly
• B. Pay attention to clients' communication needs
• C. Manage conflicts of interest fairly
• D. Client assets protection

Answer: (A)

The concept being tested is the FCA principle that pays due regard to the interests of customers and treats them fairly in all aspects of a firm's work. This principle requires firms to put customers' needs first, ensure products and services are suitable, clear, and not misleading, and act in a way that avoids harm to customers. It underpins fair outcomes and trust in the market.

This is why it’s the best choice: it directly embodies the obligation to consider and protect customers’ interests and to treat them fairly, which is the core mandate of that principle.

The other options relate to different FCA principles: ensuring communications with clients are clear and appropriate aligns with the principle on communications with clients; handling conflicts of interest properly maps to the conflicts of interest principle; protecting client assets corresponds to safeguarding client assets.
