"

In 1918, the seat was split into Woolwich East and Woolwich West. In 1983, most of Woolwich West became Eltham while the recreated Woolwich constituency was largely based on Woolwich East. In 1997, the seat was split up along different lines, with part of it going into neighbouring Erith and Thamesmead, and part of it merging with the Greenwich seat to form the new Greenwich and Woolwich seat.
