The new times will take place for the first hour that the store is open.
So, for stores opening from 10am to 4pm the quiet hours will run between 10am and 11am.
Morrisons Chief Executive David Potts said: “The introduction of the quieter hours has been appreciated by many customers who prefer to shop in a calmer environment.
“Extending them to include Sundays will offer more opportunities to shop more peacefully.”
As the demand for delivery slots has increased, Tesco has asked customers to shop in stores if possible.
To help accommodate this, they have extended opening hours in most stores, Tesco UK CEO Jason Tarry confirmed.
In a statement, he said: “To help more people shop in stores at times that are quieter or more convenient, we have extended the opening hours in many of our shops, although the majority remain closed overnight.”
The opening hours will vary between stores and customers can check their local online.
