This is set out through the Occupiers Liability Act for guidance.
An occupier includes a person who is in physical possession of the premises or a person who has responsibility for and control over the condition of the premises or the activities there carried on, or control over persons allowed to enter the premises.
The property owner is often defined as the occupier as above. They may not be at the property but they have control of who is there, what goes on and specifically how the conditions are monitored for maintenance.
If the property owner fits in this definition and dailies to take such care in all the circumstances of the case that is reasonable to ensure patrons and those on the property are reasonably safe when on it then this could result in a breach of the statutory condition of duty of care under Section 3 of the Occupiers Liability Act and trigger liability to the property owner for unsafe conditions.
