New laws take force tomorrow that will ban social gatherings of more than six people in England. If you meet up with more than five friends or family members anywhere, indoors or outdoors, you could be dispersed by police or face a £100 fine.
The harsh limit was brought in to simplify the rules after a frightening surge in Covid-19 cases and includes people of all ages, including babies and kids.
However, there are exemptions for workplaces, schools, unis, places of worship and more. And pubs and restaurants can have more than six customers in total - people must just be split off into small groups, that's all.
So what can and can't you do under the new rules - and what's happening in Wales and Scotland too? We explain the rules below.
