The Bromley parliamentary constituency was created in 1918, before which the area had been part of the larger Sevenoaks constituency. In 1974 it became Ravensbourne and in 1997, following the abolition of the old Chislehurst constituency, the seats of Ravensbourne and Chislehurst were joined and the new parliamentary constituency of Bromley and Chislehurst emerged.

Harold Macmillan was the MP for Bromley from 1945 until his retirement in 1964, when he was succeeded by John Hunt, until 1997 when Eric Forth took over as Conservative MP for the constituency.

After Eric Forth passed away in 2006, Bob Neill, who had previously been a London Assembly member, was returned as MP for Bromley and Chislehurst.

The constituency covers the northern part of the London Borough of Bromley between the towns of Bromley and Chislehurst. It is made up of six electoral wards from the borough:

Bickley, Bromley Town, Chislehurst, Cray Valley West, Mottingham and Chislehurst North, Plaistow and Sundridge.

Following their review of parliamentary representation in South London, the Boundary Commission for England made changes to the constituency. Parts of Hayes and Coney Hall ward, Shortlands ward, and Bromley Common and Keston ward were transferred to the Beckenham constituency. Cray Valley West ward was transferred to Bromley and Chislehurst from Orpington.
