Following the Poor Law Amendment Act 1834, Hornchurch and Romford became separate civil parishes in 1836 and were grouped into the Romford Poor Law Union. The area of the union, excluding the town of Romford, became a rural sanitary district in 1875. The special status of the Liberty of Havering was abolished in 1892 and the area was reincorporated into Essex. In 1894 the Hornchurch vestry was replaced by Hornchurch Parish Council. The rural sanitary district became Romford Rural District and the local authority became Romford Rural District Council. As the population of Hornchurch was rising, the parish council was abolished in 1926 and the parish was removed from the rural district. On 1 April 1926 the parish of Hornchurch became Hornchurch Urban District and the local authority became Hornchurch Urban District Council, with the first election having taken place on 27 March 1926. The council met at Langtons House from 1929. The urban district was significantly expanded in 1934 when the parishes of Cranham, Rainham, Upminster, Wennington and part of Great Warley were added. In 1936 part of North Ockendon was added to the district. The area formed part of the London Traffic Area from 1924 and the London Passenger Transport Area from 1933. The whole area was included in the London Borough of Havering in 1965 and it was transferred from Essex to Greater London. For elections to the Greater London Council, Hornchurch was part of the Havering electoral division until 1973 and then the Hornchurch electoral division until 1986.
