The village was originally split into four manors but, as time went on, these consolidated into two: Ickenham and Swakeleys. The 17th-century Swakeleys House still stands but much of the Swakeleys estate was sold for housing in the 1920s - especially in 1922. Ickenham’s manorial home was Manor Farm and this now forms part of Long Lane Farm. A military station, RAF West Ruislip, opened in 1917 and closed in 2006.
The Metropolitan Railway constructed the line through Ickenham on its Uxbridge branch in 1904. On 25 September 1905 a small halt was opened as Ickenham Halt. The railway company had been reluctant to open a station in the area and a compromise was reached with the halt.
A booking hut followed in 1910 and the platforms - previously too short for all of a train to stop at - were extended in 1922.
The station was rebuilt into its present form between 1970 and 1971 replacing the ’halt’ structures dating from 1905.
