More than 20 million UK consumers may have been overcharged for their home insurance

Find out if you might be one of them



What is the claim about?

The UK’s competition regulator, the Competition and Markets Authority, found that the price comparison website breached competition law and imposed a fine of almost £18 million.  The CMA found that ComparetheMarket used unlawful clauses in its contracts with certain home insurers, which had the effect of reducing competition between price comparison websites and between insurers listing on those websites.

Home Insurance Consumer Action, led by consumer rights advocate Kate Wellington, intends to bring a claim on behalf of all UK consumers who purchased home insurance policies, which it believes were affected by ComparetheMarket’s unlawful conduct.

ComparetheMarket is currently appealing against the CMA’s decision and Home Insurance Consumer Action does not intend to take further steps in the claim until the appeal has been concluded. If ComparetheMarket loses its appeal, Home Insurance Consumer Action will ask the court to certify the claim such that it can move to trial.

How do I know if I was affected?

Home Insurance Consumer Action’s claim is based on the allegation that ComparetheMarket’s conduct is likely to have resulted in higher prices for all consumers of home insurance, regardless of whether you bought your policy through a price comparison website, a broker or direct from your insurer.  The same allegation applies to consumers who renewed an existing home insurance policy.  So, if you bought or renewed a home insurance policy between 1 October 2015 and 1 June 2020, you might be eligible for compensation, no matter how you purchased your policy. 

Home Insurance Consumer Action’s claim is an ‘opt-out’ claim, meaning that if you fall within the class that is represented by Home Insurance Consumer Action, you are automatically included in the claim unless you choose to opt-out.  Further details of the claim and the class will be made available following the outcome of ComparetheMarket’s appeal.
