Our History


The Green Ace Motor Company was incorporated in 1938, beginning the journey for G&M. 


Due to aggressive expansion, the company moved it’s HQ to the Whitehouse area to a bigger location.


During the 1980’s, G&M was recognised as the leading UK manufacturer of Marine Diesel Generators.


Countryman Power Ltd, a leading manufacturer of land based generators, was acquired to expand the customer base.


In recent years, we have invested in new facilities offering us ideal and specialist working conditions. In 2015, G & M was incorporated by Tex Holdings PLC allowing us to join forces with other engineering companies who are also a part of Tex. G & M Tex is proudly part of the Tex Holdings PLC.


Our new state-of-the-art facilities were specially designed and build ,within the grounds of Claydon Business Park by Tex Holdings to suit our exact needs. 


2019 saw the introduction of our ECO Range, offering G&M quality industrial generators at a budget friendly cost. 


The G&M TEX logo received a refresh in June 2019. After over 80 years, we remain synonymous with Ipswich  and enjoy supporting the local community.
