Welling is a town in the London Borough of Bexley in Greater London, England. It is located in southeast London and is part of the wider London metropolitan area.
The town developed primarily during the 20th century as a suburban residential area. Welling railway station, opened in 1895, served the growing community and remains a key transport link, providing connections on the South Eastern Main Line. The station and surrounding infrastructure helped establish Welling as a commuter town for workers traveling into central London.
Today, Welling functions as a typical suburban district with residential neighborhoods, local shops, and community facilities. It lies between other Bexley communities and serves as part of the broader southeast London suburban belt.
