Price comparison sites covering car and household insurance are failing to give consumers a true picture of the products they buy, the City regulator said today.
The Financial Conduct Authority (FCA) accused some sites of focusing on the price of a policy without clearly explaining "crucial features" such as levels of cover and the excess a customer might have to pay in the event of a claim.
It has asked the industry to take action on the specific areas identified in the review and urged consumers to consider that not all products are the same and the cheapest product may not always be the best for their needs.
The FCA reviewed 14 websites between December and April, but did not identify which they were. It said an estimated one third of consumers buy their motor insurance policy through such sites.
By failing to provide clear information, the FCA said the websites are increasing the risk that consumers may buy products without understanding key features such as level of cover or excess levels and purely focus on the price.
A few websites did provide detailed information about the policies they reviewed, but the level of clarity in the market "varied significantly".
The regulator added that some sites were part of a larger insurance group or broker but did not disclose potential conflicts of interest, which is against its rules.
The watchdog concluded that consumers were not being given the right information to help them make decisions.
FCA director of supervision Clive Adamson said: "Price comparison websites have increased in popularity among consumers, with an estimated one third of consumers buying their motor insurance policy through them.
"However, our review found that they were not meeting our requirements in delivering fair and consistent outcomes for consumers. We also found, through our consumer research, that consumers had a number of misconceptions about the services they provided.
"We expect price comparison websites to take on board the findings of the review. It is also important for consumers to understand that not all products are the same and the cheapest product may not always be the best for their needs."
