All owners/managers of premises, including homeowners, have a duty of care to persons who may be affected by doors and gates on their premises. In the event of loss or injury caused by an unsafe gate or door, the injured party may be able to sue in a civil court to recover damages. Insurance cover is available for such risks, but may be prejudiced if the owner/manager has failed to maintain a door or gate to a reasonable standard.
Employers and the self-employed are additionally liable to criminal prosecution under health and safety law if unsafe doors and gates exist on premises under their control; this could include landlords, managing agents and facilities managers:

See regulation 11.
Maintenance contractors may be held liable in a civil court for any breach of their contract with the owner/manager of premises or for any loss occasioned by their negligence. More importantly, however, if their work fails to safeguard the health and safety of any person who may be affected, they may also have a criminal liability. This liability may affect an employer, a self-employed person and an individual employee. If an unsafe door or gate causes a fatality, a charge of manslaughter may be considered. Note that these duties under criminal law apply to the contractor irrespective of the type of premises involved.
