Beaconsfield was transferred to Aylesbury. Gained Eton which had been part of the abolished Parliamentary Borough of New Windsor in Berkshire. 1945–1950 The
House of Commons (Redistribution of Seats) Act 1944 set up Boundaries Commissions to carry out periodic reviews of the distribution of parliamentary constituencies. It also authorised an initial review to subdivide abnormally large constituencies in time for the
1945 election. This was implemented by the Redistribution of Seats Order 1945 under which Buckinghamshire was allocated an additional seat. As a consequence, the new constituency of
Eton and Slough was formed from the Wycombe constituency, comprising the Municipal Borough of Slough and the Urban and Rural Districts of Eton. In compensation, the parts of the (revised) Rural District of Wycombe in the Aylesbury Division, including
Hughenden and
Princes Risborough, were transferred to Wycombe. The revised composition of the constituency, after taking account of changes to local authorities, was: • The Municipal Borough of Chepping Wycombe; • The Urban District of Marlow; and • The Rural District of Wycombe.
Northern parts of the Rural District of Wycombe, including Princes Risborough, but excluding Hughenden, were transferred back to Aylesbury. Wooburn was included in the new constituency of Beaconsfield. 1983–1997 • The District of Wycombe wards of Booker and Castlefield, Bowerdean and Daws Hill, Cressex and Frogmoor, Downley, Great Marlow, Green Hill and Totteridge, Hambleden Valley, Hughenden Valley, Keep Hill and Hicks Farm, Kingshill, Lane End and Piddington, Little Marlow, Marlow Bottom, Marlow North, Marlow South, Marsh and Micklefield, Oakridge and Tinkers Wood, and West Wycombe and Sands.

Hazlemere transferred back from Chesham and Amersham. Marlow transferred to Beaconsfield and Hughenden to Aylesbury. In April 2020, the District of Wycombe, together with those of Aylesbury, Chiltern and South Bucks were merged into the new unitary authority of
Buckinghamshire Council. Accordingly, the contents of the constituency at that time were: • The Buckinghamshire Council wards of Abbey, Booker, Cressex & Castlefield, Chiltern Villages, Downley, Hazlemere, Ryemead & Micklefield, Terriers & Amersham Hill, Totteridge & Bowerdean, Tylers Green & Loudwater, and West Wycombe (part).
