Premises expecting between 200 and 799 people sit in the standard tier; those expecting 800 or more sit in the enhanced tier. The Home Office has set an implementation period of at least 24 months from Royal Assent, so the duty comes into force no earlier than April 2027, and the statutory guidance has now been published for organisations preparing ahead of that date.",[11,63,64],{},"What the standard tier asks for is deliberately low cost and procedural: having public protection procedures in place for evacuation, invacuation, which means moving people to a safe place inside, lockdown, and communication with the people on site.
