William Warne and Co Ltd

William Warne and Co Ltd was established in 1837 as a private company to manufacture rubber products. The company became a joint stock company, the directors then being Edward Gerard Coles (Chairman), Ernest Harry Coles, George Frederick Spencer Warne, Oscar Edwin Coles, and James Burbridge; Ernest. F Spencer Warne acted as the Company Secretary in 1895. The company factory was in Tottenham, Middlesex, with registered offices at 29 Gresham Street in the City of London. In 1907 the company purchased land in Barking and built a new factory there, which became its headquarters, known as India Rubber Mills.

The onset of the Second World War, trading conditions became difficult because, despite military orders, there was a shortage of raw materials. In 1945, William Warne and Co. Ltd amalgamated with the St. Alban' s Rubber Company and The London and Provincial Rubber Co. Ltd. was set up as the holding company. Their range of products was broad, aimed mainly at defence, pharmaceutical and postal markets, and ranged from precision seals for pharmaceutical inhalers and refuelling hoses for military aircraft to rubber bands for the Post Office.

In June 2000, Icon Material Technologies (Holdings) Ltd purchased William Warne and the company name was changed to Icon Warne. At the time, there were 140 employees at Barking. The Barking premises were closed in 2002 when Icon Warne based its production in Retford, Nottinghamshire.
