Aldi will extend opening hours by two hours and is encouraging shoppers to come later in the day to avoid morning queues.
Most Aldi supermarkets will open until 10pm, Monday to Saturday, from Thursday April 14.
Currently, the majority of Aldi supermarkets shut at 8pm.
Aldi is encouraging shoppers to use later hours, as the early morning has been its busiest period during the coronavirus lockdown.
Aldi says: "From Tuesday April 14, the majority of our stores will now be open until 10pm, Monday to Saturday.
"Our shelves are now well stocked throughout the day. Our busiest time is first thing in the morning, so by extending our hours you have more time to shop safely."
Sunday opening hours will remain unchanged.
Aldi has introduced priority morning queues and dedicated shopping hours for NHS, fire service and police key workers.
