An act to amend and render more effectual an Act passed in the last Session of Parliament, for building and promoting the building of additional Churches in populous Parishes.
A Commissioners' church, also known as a Waterloo church and Million Act church, is an Anglican church in England or Wales built with money voted by Parliament as a result of the Church Building Acts of 1818 and 1824. The 1818 Act supplied a grant of money and established the Church Building Commission to direct its use, and in 1824 made a further grant of money. In addition to paying for the building of churches, the Commission had powers to divide and subdivide parishes, and to provide endowments. The Commission continued to function as a separate body until the end of 1856, when it was absorbed into the Ecclesiastical Commission. In some cases the Commissioners provided the full cost of the new church; in other cases they provided a partial grant and the balance was raised locally. In total 612 new churches were provided, mainly in expanding industrial towns and cities.
