The constituency comprised the Urban District of Beaconsfield and parts of the Rural District of Amersham, transferred from the Aylesbury constituency, and the Rural District of Eton, transferred from Eton and Slough.
The constituency was abolished for the February 1974 general election, when major boundary changes split the area between the new constituencies of Beaconsfield and Chesham and Amersham. The parts of the Rural District of Amersham were included in Chesham and Amersham. Beaconsfield and the Rural District of Eton formed the bulk of the Beaconsfield constituency.
