There were major boundary changes to Bolton West in 1983 when part of its area went to create Bolton North East, but compensated by taking most of the former Westhoughton constituency. 2010 saw the town of Atherton added from the Wigan borough, previously in the Leigh constituency. In 2024, Atherton was transferred back out to the new constituency of Leigh and Atherton, and offset by the addition of Hulton ward from the abolished Bolton South East.
