Qualifying premises

A building or site mainly used for a Schedule 1 activity where 200 or more people may reasonably be expected at once.

Premises are 'qualifying' when they are wholly or mainly used for one or more uses listed in Schedule 1 of the Act (hospitality, entertainment, retail, leisure, worship, healthcare, education and more), and it is reasonable to expect 200 or more individuals present at the same time, from time to time.

Whether premises qualify is the first question to answer. If your realistic peak is below 200, the premises duties most likely do not apply — though recording why is still useful.

Who it affects: Any operator working out whether the Act applies to their building.
