Administrative/Biographical history: Gas companies were first set up in south Wales between the years 1820-1830. The provision of gas for lighting at Swansea, and Cardiff in 1821, and Newport, 1825, was so successful that other undertakings were soon set up in other regions such as Merthyr Tydfil, 1836; Pontypridd, 1850; Dowlais, 1856; and Bridgend, 1869. By the middle of the 19th century, the general dissatisfaction with the actions of many undertakings led to the passing of Acts of Parliament to regulate the industry - Gas Works Clauses Acts 1847, 1871; Sale of Gas Act 1859. During the latter half of the century, the industry saw a period of development and amalgamation, with the formation of holding companies and the acquition by local authorities. In the Rhymney Valley, a succession of small undertakings came into being: Caerphilly Gas Light Company and Water Works Company Ltd, 1869; Hengoed Gas and Water Company Ltd, 1877; Bargoed Gas and Water Company Ltd, 1877; Rhymney and Aber Valley Gas and Water Company Ltd , 1878. All these companies were amalgamated by a Special Act of Parliament in 1898 under the title of the Rhymney and Aber Valleys Gas and Water Company. From the 1880s to the boom years after the First World War, there was a growing demand for gas, and attempts were made to extend and improve the various production plants within the region. However, the Depression affected the Welsh gas industry, and some smaller companies went bankrupt and amalgamations continued. In 1949, the gas industry was nationalised and the Wales Gas Board became the first public industry to serve the whole of Wales.
