Waitrose, John Lewis, Tesco and Aldi have become the latest retailers to say they will encourage customers and shop workers to continue wearing masks after July 19.
On Wednesday evening, fellow supermarket chain Sainsbury’s said it will encourage all customers to wear a face covering if they can after ‘Freedom Day’.
It comes after the Government published guidance for businesses which said it "expects and recommends" masks to be worn by workers and customers in crowded, enclosed spaces as the work from home order ends.
Staff and customers at Waitrose and John Lewis have also been urged to continue wearing masks but bosses say it will ultimately be up to individual judgment.
Perspex screens and hand sanitising stations will remain in place throughout outlets.
Meanwhile Tesco has said social distancing, alongside other measures, will remain place across its shops.
Last week, the supermarket started an internal review regarding its mask-wearing policies ahead of the latest easing of restrictions.
The firm said it will continue to have capacity limits in its stores, protective screens at checkouts, hand sanitiser stations and regular cleaning after speaking with customers and colleagues.
A Tesco spokesman said: "Since the start of the pandemic, we have focused on ensuring everyone can get the food they need in a safe environment.
"Having listened to our customers and colleagues, we will continue to have safety measures in place in our stores; these include limiting the number of people in store at any time, protective screens at every checkout, hand sanitiser stations and regular cleaning.
"We’re asking our customers and colleagues to be on the safe side, and so from July 19 we’ll be encouraging our colleagues to wear face coverings whilst they work and encouraging our customers to do the same when they shop with us."
Covid rules from July 19
Asda will have signage and announcements to encourage customers to follow Government guidance and will continue to provide face coverings in shops for people who wish to use them.
A spokesman said: "We encourage customers to be respectful to each other and to follow the Government guidance on face coverings when shopping in our stores after 19 July."
A spokesman for the John Lewis Partnership, which also manages Waitrose, said: "In line with Government guidance, we will recommend that our customers and partners in England continue to wear a face covering, unless exempt, from July 19.
"The decision over whether to do so or not, when in our shops, will be for each individual to take, based on their own judgment.
"Across all of our stores we will be retaining perspex screens and hand sanitising stations.
"We will also maintain all of the hand hygiene and store cleaning disciplines which have served us well since the start of the pandemic."
The retail group added that it will continue to follow legislation in Scotland and Wales which requires customers and employees to wear masks, unless exempt.
Face masks poll
Aldi also confirmed its position on masks in its stores in the wake of the guidance from Government.
An Aldi spokesman said: "From Monday July 19, we’ll continue to encourage customers and colleagues to wear face coverings when they’re in store. Other measures like hand sanitisers and screens will also stay in place.
"Face masks are still required for customers and colleagues in our Welsh and Scottish stores, in line with the latest guidance."
