The old parish of Ickenham was situated between the River Pinn and the Yeading Brook, adjacent to Hillingdon parish. It covered around 1,458 acres. In 1937 the civil parish merged with Uxbridge and since 1965 the are has been part of the borough of Hillingdon. The parish comprised farmland and fields until the construction of the Metropolitan Line extension in 1904, which encouraged the construction of residential houses.

The Victoria County History of Middlesex notes: "at the inclosure of 1780 the open fields of Ickenham amounted to 683 acres. They began near the junction of Glebe and Austin lanes and covered the south of the parish. To the north of the Yeading Brook were Tipper Hill and Woe Acres. Two meadows in the parish were called Brook Mead. One was on the Ickenham bank of the Pinn near Beeton Wood, the other lay along the southern bank of the Yeading Brook where it entered the parish north of the modern airfield. Adjoining this Brook Mead was Ickenham Marsh. Middle Field and Bleak or Black Hill were inside the loop of the Yeading Brook on the banks of which were also Tottingworth Field, Swillingtons, Further Field, and Down Barnes Hill, which lay further to the south. Many of these fields are visible from the point where Western Avenue crosses the Yeading Brook. Bleak Hill, mentioned as early as 1367, rises gradually to about 8 feet above the level of the road and is topped by a clump of trees."
