An investigation by the Competition and Markets Authority (CMA) has concluded that, between December 2015 and December 2017, the price comparison website ComparetheMarket breached competition law by imposing wide ‘most favoured nation’ clauses on providers of home insurance selling through its platform. These clauses prohibited the home insurers from offering lower prices on other comparison websites and protected ComparetheMarket from being undercut elsewhere. They also made it harder for ComparetheMarket’s rivals to expand and challenge the company’s already strong market position as other price comparison websites were restricted from beating it on price.
As a result, competition between price comparison websites, and between home insurers selling through these platforms, was restricted. The CMA found that this is likely to have resulted in higher insurance premiums.
