Despite the changes in ward names, the 1974–1983 boundaries and the 1983–1997 boundaries are almost exactly the same boundaries. Similarly, despite the changes in local authorities and the listing of wards, the 1950–1974 boundaries and the 1997–2010 boundaries are almost exactly the same.

Beckenham constituency covers the northwestern part of the [[London Borough of Bromley]]. The local government ward boundaries were redrawn for the [[2002 Bromley London Borough Council election|2002 local elections]], though this did not affect parliamentary limits until the 2010 general election.

===Pre-2010 boundary review===
Following their review of parliamentary representation in [[South London]], the [[Boundary Commission for England]] made revisions to this seat. Clock House ward, [[Crystal Palace (Bromley ward)|Crystal Palace ward]], and Penge and Cator ward were transferred from Beckenham to help create the new constituency of [[Lewisham West and Penge (UK Parliament constituency)|Lewisham West and Penge]]. Parts of Bromley Common and Keston, [[Hayes and Coney Hall (ward)|Hayes and Coney Hall]], and Shortlands wards were transferred to Beckenham from [[Bromley and Chislehurst (UK Parliament constituency)|Bromley and Chislehurst]]. A small part of Bromley Common and Keston ward was transferred to Beckenham from [[Orpington (UK Parliament constituency)|Orpington]] and a tiny part of Bromley Town ward was transferred from Beckenham to Bromley and Chislehurst.

===Abolition===
Under the [[2023 Periodic Review of Westminster constituencies]], the constituency underwent major boundary changes, with eastern areas, comprising the [[Bromley Common]] and [[Keston]], and [[Hayes and Coney Hall (ward)|Hayes and Coney Hall]] wards, being transferred to the new constituency of [[Bromley and Biggin Hill (UK Parliament constituency)|Bromley and Biggin Hill]]. To compensate, "[[Penge]]" (comprising the Clock House, [[Crystal Palace and Anerley (ward)|Crystal Palace]], and Penge and Cator wards) was transferred back from the now abolished seat of [[Lewisham West and Penge (UK Parliament constituency)|Lewisham West and Penge]]. Accordingly, the seat was renamed [[Beckenham and Penge (UK Parliament constituency)|'''Beckenham and Penge''']], first contested at the [[2024 United Kingdom general election|2024 general election]].<ref name=":0" /> With the new boundary changes it was notionally a marginal seat but was won by [[Liam Conlon]] for Labour with a majority of 12,905.
