The supermarket chain, which has more than 1,400 stores across the UK, is asking its customers and colleagues in England to continue wearing masks, unless exempt.
Mandatory mask-wearing in England is to be ditched from January 27, as part of the government’s rolling back of Plan B measures in England, along with other restrictions including Covid-19 certification.
The retail giant said face masks will still be mandatory in Scotland and Wales, in line with each devolved nation’s latest government guidelines.
A spokeperson for Sainsbury’s said: “Safety remains our highest priority. From Thursday, we’re asking our customers and colleagues in England to continue to wear a face covering in our stores if they are able to.
“In Scotland and Wales face coverings remain mandatory for those who can wear them in our stores, in line with the latest Government restrictions.
“We continue to have a range of safety measures in all of our stores, including screens and sanitising stations.”
From January 27, there is no longer a legal requirement to wear a face covering in England, although they are still recommended in crowded and enclosed spaces where social mixing takes place.
They are legally required in shops and most public settings in Scotland, Wales and Northern Ireland.
