The Rhosllanerchrugog gasworks was in existence in 1864, when an advert was placed for a tender to construct a residence at the gasworks for a Mr W. E. Crake the gasworks superintendent (Wrexham and Denbighshire Advertiser 1st October 1864). The Rhos Gas Company Ltd. supplied Rhosllanerchrugog, Ruabon, Wynnstay, and Johnstown. The original gasworks were built by W.C. Holmes of Huddersfield. These gasworks were put up for sale by auction, although not as a going concern, the advert placed read “ SOLD BY PUBLIC AUCTION or otherwise by PRIVATE CONTRACT, Rhosllanerchrugog GAS WORKS, with all the buildings and erections, furnaces, steam and other engines, implements and utensils of manufacture, machinery, tools, retorts, pipes, mains, gasholders and meters, fitters, purifiers, cranes, gear tackle, and other the appurtenances thereto, and the parcel of land containing the site thereof”(Wrexham and Denbighshire Advertiser 11th February 1871). These gasworks appeared on the 1873 to 1875 OS maps, which suggested they were removed in favour of the new gasworks.
