Well Hall is a place to the north of Eltham in the Royal Borough of Greenwich in southeast London, England, with no present formal boundaries and located 13.5 km (8.4 mi) east-southeast of Charing Cross.[1][2] In the past Well Hall was the grounds of a manor house, and then a hamlet. Today it is a largely residential suburb and housing estate absorbed by the development of Eltham and London. It is centred on the main road between Eltham and Woolwich, on which many shops and businesses are located. Several major A roads including the South Circular Road and A2 road pass through the area, as does a railway line, serving Eltham station which is located in Well Hall.[2] The Postcode that covers Well Hall and most of the Eltham area is SE9, and the 020 dialing covers the entire Royal Borough of Greenwich. Well Hall is split across two electoral wards, Eltham West on the west side of Well Hall Road, and Eltham North on the east side of Well Hall Road. In 2015 the population of these two wards combined was recorded as 24,621, although the wards cover a larger area than just Well Hall.
