The sash window assembly 1 comprises a sash 15 slidable in a frame 11; a counterweight mechanism comprising a counterweight 25, a pulley wheel 20 and a chain 24 (optionally a rigid or push-pull chain) fixed to the sash and the counterweight and engaging teeth of the pulley wheel; and a drive mechanism comprising an electric motor 30 to rotate the pulley wheel and move the sash. The chain may comprise one end fixed to the sash and another fixed to the counterweight. The drive mechanism may comprise a shaft 22 extending from a lower to an upper portion of the frame, optionally connected to the pulley wheel via a worm drive. There may be a clutch to disengage the pulley wheel from the motor, e.g. by disengaging the worm drive. There may be a wireless controller and/or a sensor to close the sash in rain. The assembly is particularly suitable for an existing form of window, e.g. in a heritage building.
