Originally based in North Yorkshire, Allan Green & Son have grown and adapted since founded in 1925. The relationship with existing clientele have developed over the many business years and Allan Green & Son constantly welcome new customers.
In 2011, Allan Green & Son was acquired by Acetarc Limited, an engineering company based in Keighley. Allan Green & Son had been a long-time supplier of gears to Acetarc, meaning the buying and relocating of the company allowed both companies to work together to enhance all aspects of the businesses and expand on the Greens machining capability. Like Allan Green & Son, Acetarc is a family run business and to honour the history of the long-established company, Acetarc decided to preserve the name Allan Green & Son.
