Healey New Mill was built in 1826-27 as a steam-powered "scribbling and fulling" mill by Benjamin Hallas, an established Ossett clothier and was then sold in 1836 to a partnership of 29 local Ossett clothiers who ran the mill under the style "The Healey New Mill Company."
The original mill, constructed of stone and brick and being 3 storeys in height, had an engine house between the main working area of 8 bays and a 2 bay narrower end, perhaps used for warehousing.
The mill is of fireproof construction with cast-iron beams and joists and a stone-flagged floor. Minor buildings included a dyehouse and a single-storeyed heated cloth dryhouse. After 1881 the mill was used mainly for the manufacture of Shoddy and Mungo, and for a rag warehouse and a rag-grinding shed.
In 1929 the mill was sold to Wilson Briggs and Norman Briggs, rag merchants, who traded as "Wilson Briggs & Sons" (later becoming a limited company in 1947). During their ownership the mill was used for Mungo and Shoddy Manufacture, and rags were stored in the original 3-storey mill.
The mill was run during the Second World War (1939-45) by Arnold Briggs, Wilson's son, and the company during this period manufactured material for khaki army uniforms and also for blue Royal Airforce uniforms, and Arnold ran the company until his death in the 1974.
The site which is now divided into individual industrial units was purchased from the great-grandson of Wilson Briggs.
