It was formed around 1695 when Thomas Reynolds was called as minister. In 1697 the congregation built a meeting house over the King's Weigh House in Little Eastcheap, and from this home the church took its name. The King's Weigh House was where "Merchant Strangers" were required to have their goods weighed so that customs duties could be assessed, and was rebuilt after the Fire of London. Reynolds ministered until 1727, then James Wood, 1727–42; William Langford, 1742–75; Samuel Wilton, 1776–1778; and John Clayton 1778-1826. Thomas Binney, 1829–69, was one of the notable Congregational ministers of the nineteenth century. During Binney's time the Weigh House site was required for widening the approaches to London Bridge. In 1833-4 a new building in Fish Street Hill designed by William Tate and seating 1000 people was erected. Prominent members during this period included Samuel Morley and George Williams who founded the YMCA in 1844. Binney was succeeded by William Braden, then Alexander Sandison, 1880-1901. In 1882 the church site was compulsorily purchased by the Metropolitan Railway. By now many members lived in the suburbs and there was less need to relocate in the City. The Duke of Westminster offered a site in Mayfair, part of which was occupied by a small Congregational church in Robert Street. The offer was accepted and in 1891 the new building in Duke Street, designed by Alfred Waterhouse was opened. It cost £30,000. Sandison was succeeded by John Hunter, 1901-4, F.A. Russell, then E.W. Lewis. The next minister Dr William E. Orchard ministered from 1914. During his pastorate the style of worship became increasing Catholic, and after Orchard's resignation in 1932, he joined the Catholic Church. Notable is the fact that in 1917 Claud and Constance Coltman were ordained as assistant ministers, the latter being a member of the church before training at Mansfield College, Oxford and the first woman to be ordained in a mainstream English denomination. The next years were ones of decline. On 20 October 1940a bomb fell on the chancel during a communion service, killing the minister's wife and injuring one other. The building was requisitioned as a fire watching centre and rest centre. In 1945 22 members decided to revive the work and appointed W.J.E. Jeffery as minister, with assistance from Claud and Constance Coltman. After war damage reinstatement the building was formally rededicated in 1953. In 1956 Daniel Jenkins was appointed as minister with the aim of providing a distinctive mission within central London but the work did not develop as hoped. In 1962 Jenkins accepted the invitation to become the first chaplain of the University of Sussex. Roger Tomes was appointed as minister with aim of guiding the small Weigh House congregation towards union with another church. Following friendly discussions with Whitefield Memorial Church, Tottenham Court Road, separate services at the Weigh House ended in July 1965. In March 1966 the decision was taken to formally disband the church and dispose of the building. It is now the Ukrainian CatholicCathedral of the Holy Family in Exile
