In Medium Local Covid Alert Level areas (Tier 1) it is against the law to gather in groups of more than 6, unless everyone is from the same household and support bubble. In High (Tier 2) and Very High (Tier 3) areas, it is against the law to gather indoors in groups which do not consist only of the same household and support bubble. A number of exemptions apply. For example, some activities - such as those organised for under-18s including education or training supervised activities provided for children, including wraparound care, youth groups and activities - are exempt.
In addition, in a COVID-secure venue or public outdoor place, non-professional performing arts activity, including choirs, orchestras or drama groups can continue to rehearse or perform together where this is planned activity in line with the performing arts guidance and if they can do so in a way that ensures that there is no interaction between separate and distinct groups of no more than 6 (In Medium areas and outdoors) or individual households (in High and Very High areas) at any time (depending on Local Covid Alert Level restrictions). If an amateur group is not able to ensure that no mingling takes place between these sub-groups (depending on Local Covid Alert Level restrictions) - including when arriving at or leaving activity or in any breaks or socialising - then such non-professional activity should not take place. Local Covid Alert Level guidance (Medium, High, Very High) provides details on group size.
