The UK competition authority has provisionally decided that ComparetheMarket's "most favoured nation" clauses with home insurers are anti-competitive. Such clauses (also known as "parity" clauses) typically entitle a platform (in this case a comparison site) to display the best rates (in this case insurance) being offered by the supplier on other sites.
The watchdog believes the relevant clauses in ComparetheMarket's contracts prevent better insurance deals being offered on other sites. Similar clauses have been investigated by competition authorities in the past, e.g. in relation to hotel online booking and online auction service providers.
ComparetheMarket will now have an opportunity to defend the allegations and the ultimate decision will be of interest to online platforms in the UK and abroad, given that similar competition law principles apply across the world.
