As well as on public transport, face coverings are mandatory in all shops, supermarkets, indoor shopping centres, banks, transport hubs and post offices in England. As well as indoor settings where you're likely to come into contact with people you don't normally meet, including cinemas, museums, galleries and places of worship.
On 22 September, Boris Johnson announced the latest rules to combat the rise in coronavirus cases, and the law on wearing a face mask has now been extended to include staff in retail, people in taxis and private hire vehicles, and everyone using hospitality services – for example walking to your table or the toilet during a meal; this was previously only the case if you were getting a takeaway. Those who have certain medical conditions, as well as children under 11 are exempt.
Mr Johnson also told the House of Commons that fines for failing to wear a face mask will rise from £100 to £200 for a first-time offence.
Face covering requirements also apply to the rest of the UK. In Scotland, it's compulsory to wear one in shops and has been on public transport since June – including the Glasgow Subway, Edinburgh trams and taxis – except for people with certain medical conditions and children under five.
In Wales, face coverings are mandatory on public transport as of 27 July, including in taxis. The Welsh Government is also advising people to wear masks in crowded places where social distancing is not possible, but this is not compulsory.
Face coverings are also compulsory on public transport in Northern Ireland and The Republic of Ireland, and will be mandatory in shops from 10 August.
In Scotland, secondary school students will be obliged to wear a face covering in corridors, communal areas and on buses from Monday 31 August.
From 1 September in England, staff and pupils in secondary schools in local lockdown areas like Manchester and Birmingham will be required to wear face coverings when moving around the building and in communal areas where social distancing is difficult to maintain, while for other parts of the country, masks will not be obligatory, but schools will have the discretion to make them mandatory in communal areas should they feel it is necessary.
Wales is currently reviewing its policy on mandatory face masks for pupils ahead of schools reopening.
As a result, many retailers and small businesses have started selling face coverings and they are now even available in supermarkets.
With some selling masks individually and others also offering multipacks, supermarkets provide an accessible way to buy a face covering before the rules change in England.
If you don’t want to buy one online, don’t have access to the Internet or are looking to get one for an older family member or neighbour, simply pick one up on your next weekly shop.
