description An activation apparatus (10) for activating a downhole tool comprising a top sub (12), a bottom sub (14), an outer sleeve (16) having a port (18) and an inner sleeve (20) having a port (22). The apparatus (10) is configurable between a run-in configuration in which the ports (18, 22) are not aligned and an activated configuration in which the ports (18, 22) are aligned and permit lateral passage of fluid through the apparatus (10), the activation apparatus (10) being configured such that application of at least two forces to the activation apparatus (10) transitions the activation apparatus (10) from the run-in configuration to the activated configuration.
