Supermarkets have regularly updated customer rules during the coronavirus pandemic. Tesco, Asda, Sainsbury’s, Marks and Spencer and Aldi have all issued guidance on their face mask policies.

Information on how to deal with the coronavirus has been constantly updated.

In May, a government document stated: “If you can, wear a face covering in an enclosed space where social distancing isn’t possible and where you will come into contact with people you do not normally meet.

“This is most relevant for short periods indoors in crowded areas, for example on public transport or in some shops.”

Some people have since worn face coverings when visiting supermarkets, but what are the official rules?

Tesco

The supermarket chain has not has not made wearing masks compulsory for customers or staff, although they are available if staff wish to wear them.

Instead, social distancing measures have been introduced, including how many shoppers can shop at one time.

The retailer previously said the government guidance refers to indoor spaces where social distancing is not possible.

Asda

The supermarket giant has also left the choice up to customers when they visit stores.

A spokesman said: “We are complying with all Government guidelines and we welcome customers wearing face masks or not.

“Our colleagues all have the option of wearing face masks which we have supplied and the colleagues in clinical settings (pharmacy and optical) have been required to wear masks since the start of the pandemic as per the government guidelines on clinical workers.”

Aldi

Aldi issued face masks to all staff early on in the pandemic but it is not compulsory for them to wear.

“Aldi will be providing the option of face masks to all its store-based colleagues to further support their safety as they continue to feed the nation,” a statement said.

“This move is in addition to the previously announced provision of gloves and clear screens that are being installed at more than 7,000 checkouts.

“Colleagues can also now access the Government’s Covid-19 testing programme for critical workers.”

Customers also have the choice of whether they want to wear a face covering or not.

Sainsbury’s

Similar to its rival, the supermarket chain has masks available for all colleagues should they wish to wear them.

A spokesman explained: “Masks are available for all our colleagues who wish to use them while they work or travel to their place of work.”

However, no one in the store is made to wear these and social distancing measures have been introduced to keep shoppers safe.

Marks and Spencer

M&S Foodhall stores have remained open throughout the pandemic and made changes to how operations are run.

Face visors have reportedly been available to staff since the beginning of April.

However, wearing the visors – or any face coverings – is not enforced.

In most supermarkets, wearing a face mask has not been enforced but may be something shoppers choose to do.

Where to buy? 

Those who do choose to wear a face mask can pick one up at many retailers online and in store.

ASOS are offering reusable black face mask, two for £12, and a selection of non-medical face coverings can be picked up from Boden, £20 each.

Etsy are listing  face masks with filter pockets, starting at £2.49, and reusable cloth masks, £12, can be ordered on Casetify in a range of colours.
