The Bellingham Estate is bordered to the east and west by railway lines running south from Catford. Along the south it is bordered by Southend Lane, the A2218 main road. The River Ravensbourne runs through Bellingham, although it is either underground or part of a man-made section of the river. The Prime Meridian passes to the east of Bellingham.
