Upminster formed an ancient parish of 3,369 acres (1,363 ha) in the Chafford hundred of Essex.
The parish vestry had meetings in the church until 1798, when they moved to the Bell Inn.
The parish was divided into North and South wards by the Hornchurch to Cranham road.
In 1836 the vestry lost control of poor relief, with Upminster becoming part of the Romford Poor Law Union and in 1875 the parish became part of Romford rural sanitary district.
Following the Local Government Act 1894, the sanitary district became Romford Rural District and a parish council was formed of nine members, increasing to twelve by 1913 as the population had doubled.
The parish council acquired the Clock House building on St Mary's Lane for use as offices in 1924.
The parish formed part of the London Traffic Area from 1924 and the London Passenger Transport Area from 1933.
In 1934 the parish council was abolished and Upminster was combined with other parishes to form part of Hornchurch Urban District.
In 1965 the urban district was abolished and its former area was combined with that of Municipal Borough of Romford; and since then has formed part of the London Borough of Havering in Greater London  as set out in the 1963 London Government Act</ref>
