The FSA is concerned insurers may fail to change their systems in time to comply with the ban on gender-based pricing which will be introduced on December 21.
The European Court of Justice ruled last March that insurers can no longer use gender as a factor in pricing.
In its retail conduct risk outlook, published today, the regulator says the ruling creates a number of potential concerns.
It says: “Our primary concern on the transition to unisex premium pricing is that firms fail to make appropriate or timely changes to their systems and controls to ensure the pricing of insurance products is in line with the new requirements.
“It will be important for there to be clear communication to consumers, particularly when issuing illustrations around the time the change is implemented in December 2012.”
The FSA is also concerned that consumers may not receive sufficient information about changes to existing products or quotations obtained immediately before December 21.
The regulator says another potential issue is that insurers withdraw from the market or from certain product lines as a result of the ban.
It adds firms need to ensure they have the appropriate systems and controls in place in enough time to meet the statutory deadline of December 21.
