This version of the guidance has been updated to provide clarity on indoor group activity after the Government announced tighter restrictions for indoor sports activity. In relation to indoor group tennis activity, from Thursday 24 September:

• Organised indoor group tennis activity for adults (including coached sessions and club nights held indoors) can take place in larger numbers in COVID-19 secure venues, provided it is organised into sub-groups of no more than six people (excluding coaches) - these sub-groups should stay separate and not mix for the duration of the session.
• There is an exemption for activity for disabled people, which can take place in any number.
• Organised group indoor activity for children is unaffected by this change and can continue as before in line with the limits for outdoors (groups of up to 15 children).
