Venues following COVID-secure guidance can host more people in total, but no one must mix indoors with anyone who they do not live with (or have formed a support bubble with) unless exemptions apply. Outdoors, you can meet in groups of up to 6 people.
This includes in:
pubs and restaurants
leisure and entertainment venues
places of worship
At least one person in your group should give their contact details to the venue or check in using the official NHS COVID-19 app so NHS Test and Trace can contact you if needed.
