There is provided a leading edge structure (1, 2, 4) for an aerofoil. The leading edge structure (1, 2, 4) comprises a skin (10, 30) configured to form an external aerodynamic surface of the aerofoil. The skin (10, 30) comprises a plurality of first regions (11, 21, 31, 41) interleaved with a plurality of second regions (12, 22, 32, 42). Each first region (11, 21, 31, 41) comprises a plurality of holes (13, 33, 43) extending through the skin (10, 30), and each second region (12, 22, 32, 42) comprises an electrical heating system (14, 44) configured to increase the temperature of the skin (10, 30).
