Although the legal requirement to wear face masks in shops and indoor business settings has been scrapped in England as of July 19, government guidance states people will still be "expected" to wear masks in crowded, enclosed spaces.
The guidance also applies to offices, factories, construction sites and close contact services such as hairdressers.
The disparity between the law and guidance has created confusion, but it simply means businesses, not the government, will be responsible for making and enforcing any face mask rules from Monday.
The government defended the guidance saying they were "trusting" the public and businesses "to do what's right for them and their staff."
'We're respecting the fact that there's a whole variety of different settings across the country', says Communities Secretary Robert Jenrick
Communities Secretary Robert Jenrick told ITV News: "We're respecting the fact that there's a whole variety of different settings across the country and, if we're going to be living with the virus for a long time, it's right that we have that more varied approach rather than a one-size-fits-all one where the force of the law stands behind it."
