History of Slough boundaries and wards The Slough local government area came into existence in 1863. It comprised a part of the parish of Upton-cum-Chalvey, roughly corresponding to the modern Central and Upton wards. In 1894 Slough became a civil parish and then an Urban District. In 1900 the boundaries of the Slough district were expanded for the first time, increasing its size to . The northern boundary was extended up Stoke Road, as far as the Slough branch of the Grand Union Canal. To the south and west, Chalvey and the Salt Hill area, as far as the Montem Mound, were absorbed. To the east, part of Langley joined the district. The Agar's Plough area left Slough, to become part of Eton and provide playing fields for Eton College. In 1930-1931 there was a major extension of the boundaries, increasing the district to . Parts of the parishes of Burnham, Dorney, Farnham Royal, Horton, Langley Marish and Stoke Poges were added to Slough. Slough was first warded in 1930. The original seven wards were Burnham, Central, Chalvey, Farnham, Langley, Stoke and Upton. The town was re-warded in 1950, when four of the previous wards (Burnham, Central, Farnham and Stoke) were split into north and south wards, to make a total of eleven. Britwell and Wexham Court were added to Slough in 1973 (when these two new wards and the eleven existing wards were allocated between two and nine seats, instead of the three per ward which had existed previously). There was another re-warding in 1983, which created thirteen three-member wards with revised boundaries. Colnbrook & Poyle was added to Slough in 1995 and became a fourteenth ward, with one member 1995-1997 and two from 1997. For Slough Council election 2004 the Borough
