The accessory 10 comprises an elongate housing 12 for securing to the lower end of the ladder and two stabilising arms 14, 16 retractably received within the housing, and which are spring biased to extend laterally in opposite directions, and which are retained within the housing when not deployed by a catch mechanism 24, 26 that is automatically released by resting the ladder on the ground. The arms may have a pivotably attached foot 28 including a hook 24 for retaining the arm, wherein ground contact rotates the foot, disengages the hook from the housing and deploys the arm. The arms may extend coaxially from the housing, be arranged adjacent each other when in the housing, and be telescopic. Also claimed is an accessory where the catch is released by applying a downward force to an actuator on top of the accessory, and an accessory where the catch mechanism is released by applying a force to vertically displace the arms.
