Bristow Helicopters Limited was established in June 1955 by Alan Bristow.

From 17 February 1965 and onwards, it operated the Westland Wessex 60 ten-seat helicopter in support of North Sea Oil industry off-shore installations.

During the late 1960s, Bristow operated a fleet of Hiller UH-12 training helicopters based at AAC Middle Wallop which were used to train flight crews for the UK Army Air Corps.

In 1985, it was acquired by British and Commonwealth Holdings plc.
