The High Court has ruled in favour of a group of businesses, including PizzaExpress, seeking insurance payouts for Covid-related losses.

The judgment applies to more than a dozen other claimants, including a Mayfair nightclub and London’s ExCeL venue, which is seeking a £16m payout against insurers including RSA and Allianz.

The Financial Times reports the judgment is predicted to unleash a wave of insurance claims.

Earlier this year, the Supreme Court decided that businesses with applicable policies could claim if there had been a Covid case in the vicinity of their premises.

The judgment, announced last week, extends to another group of insurance policies with clauses that cover businesses for the closure of their sites due to Covid cases on the premises.

Insurer losses for Covid-related business interruption claims have increases as courts find in favour of policyholders, with a total of £1.7bn paid out in partial or final settlements to businesses, according to the Financial Times.
