The word “consequential” means something following as an effect or result. It is an indirect result of the occurrence that causes the loss.
The difference between a direct loss and a consequential loss can be seen in the destruction of a power station by wind. The damage to the power station is a direct loss by wind. There is actual physical damage directly resulting. The destruction of the power station also interrupts the generation of power by the station. For example, a cold storage plant is without electrical power. Foodstuffs spoil as a result or as a consequence. This is a consequential loss, not a direct loss.
