The Mountain Ash Local Board Act of 1885 would enable the Local Board to construct and maintain Gas Works and Water Works and to manufacture Gas, it included the purchase of the Penrikyber Gas and Water Company Limited and the gas and water assets of the Nixons Navigation Company Limited. In 1886 Mountain Ash UDC purchased both the Company and the gas supply interests of Nixons. A new gasworks was established at Penrhiwceiber providing gas for Abercwmboi and Ynysybwl. The gasworks were visible on the 1875 to 1900 OS maps, which suggests the gasworks had closed and were removed.
