Most of the country is under tougher rules than before the lockdown after government scientists warned previous measures were not effective enough to stem rising Covid-19 infections.
Only a handful of areas have been placed in tier 1, where the restrictions are the most limited. In this tier, socialising is restricted to groups of six indoors and outdoors, people are urged to work from home if possible, and pubs are limited to table service.
Large swathes of the country is under tier 2 restrictions with a ban on households mixing indoors. Pubs and restaurants only able to sell alcohol with a “substantial meal”.
After health secretary Matt Hancock’s latest update on Thursday, 38 million people will move into tier 3 as of Saturday.
In tier 3, households are banned from mixing except in limited outdoor settings such as parks. Bars and restaurants are to be limited to takeaway or delivery services and people would be advised to avoid travelling outside their area.
