A flooring module (100) for forming a temporary access floor comprises a base component (1) defining a cruciform channel formation (3, 4) for receiving cabling or the like. The channels (3, 4) have a floor (1A) defined by the base component and a removable channel cover (2). The channel cover (2) comprises one or more channel cover components for covering the channel formation, such that the channel formation and channel cover may combine to provide a closed channel for the cabling or the like. Removal of the cover (2) allows access to the channel formation from above, in use. The sides of the base component (1) define module connector clips (20, 21) for engaging with corresponding module connector clips on adjacent modules to lock the modules together in an array. The base component (1) defines retaining formations (13, 14) for engaging with and retaining the channel cover components over the channel formation. The channel cover (2) engages against one or more of the module connector clips (20, 21) when in the clips are in the closed position so as to limit deflection of the module connector clips (20, 21) and thus prevent disengagement of the module clips from the module clips of an adjacent flooring module in an array of flooring modules. The sides of the module preferably also include a plurality of levelling clips (41, 42) which define upward and downward facing engagement faces to prevent vertical misalignment of the modules.
