Sports clubs and grounds under Martyn's Law
Sports grounds are a qualifying use. In scope from 200 present at the same time, and enhanced tier at 800 or more. Existing ground safety certification does not remove the duty, though much of the groundwork will already exist.
Grounds and clubhouses are assessed separately
A club may have a stadium in scope at enhanced tier and a clubhouse well below the threshold, or both in scope at different tiers.
Work premises by premises, on how each is wholly or mainly used and how many people may reasonably be expected in it.
Existing safety work is not the same duty
Sports ground safety certification and the Green Guide address crowd safety. Martyn's Law addresses reducing vulnerability to, and the risk of harm from, acts of terrorism. They overlap but they are not the same obligation.
In practice a certificated ground will already have much of what is needed — stewarding, communications, evacuation planning — but the procedures still have to exist in the form the Act requires.
Open-air grounds and the entry-control test
Open-air recreational land with no entry controls is excluded from the Act. A public recreation ground is generally outside it.
That exclusion falls away where there are entry controls. A ticketed match on the same field is not excluded, and a controlled facility within a park is not excluded.
Match days versus ordinary days
Judge on realistic peak, which for most clubs means a well-attended fixture rather than a quiet training evening.
Include stewards, catering, media and ground staff in the figure.
