Neeld died on 24 March 1856, causing a by-election in Chippenham, and leaving no legitimate heirs; he willed his property to his brother John. His name is commemorated in the Neeld Hall in Chippenham, as well as a row of cottages in Hendon which was built in 1870. In Grittleton itself, his name lives on in the name of the village pub, the "Neeld Arms", and in the east window of the church of St Mary the Virgin, accompanied by a plaque stating the window to have been "erected and dedicated by his (18) Friends and Tenants (71)". In Maida Hill, North Westminster, formerly the Borough of Paddington, there are also a "Neeld Arms" and a Grittleton Road. Grittleton House became Grittleton House School, which closed in 2016. Neeld's collection of art was split up, some pieces now being in the National Portrait Gallery and some in the Victoria and Albert Museum.
