A stabiliser for ladders comprises a rigid, generally flat base (10; 71) having a linear channel (11; 70) extending along a first, upper surface thereof, which channel is defined by a pair of generally parallel, upwardly-extending side members having upper edges directed towards each other, and at least one ladder attachment (18, 19; 30, 35; 50, 53) by means of which a ladder stile (17; 66, 67) may be extended downwardly.
