The company warned in August that while it had been trading profitably before coronavirus struck, earnings had been declining for the past three years.
Pizza Express said at the time: "The unavoidable reduction in revenue as a result of the lockdown, combined with higher costs associated with reopening restaurants and uncertainty about the shape of the UK economy’s recovery, mean that the Group’s rental cost base is no longer sustainable."
355 Pizza Express restaurants are currently open in the UK. Pizza Express operates 449 restaurants in the UK. The company closed all its UK restaurants on March 23 after the Government-mandated lockdown.
Pizza Express has also put itself up for sale and has hired investment Lazard to find a buyer. The company did not say if it had received any offers.
