According to the Department of Health and Social Care under Plan B, the government expects that mandatory vaccine-only certification for visitors to venues and events, and vaccine-or-test certification for the workforce would be introduced for the following venues and events:
• all nightclubs, and other venues open after 1am with alcohol, music and dancing
• indoor, crowded settings with 500 or more attendees where those attendees are likely to be in close proximity to people from other households, such as music venues or large receptions
• outdoor, crowded settings with 4,000 or more attendees where those attendees are likely to be in close proximity to people from other households, such as outdoor festivals
• any settings with 10,000 or more attendees, such as large sports and music stadia
They have now issued a proposal for mandatory covid certification in a Plan B scenario call for evidence.
