United Oilseeds was founded in 1966 by a small group of Hampshire farmers who were looking for an effective break-crop from continuous barley. The purpose of the organisation was to develop and market the valuable rapeseed crop on behalf of its farmer members. United Oilseeds has since grown to be one of the largest and most successful specialist farmer co-operatives in Great Britain. Membership has expanded dramatically since those early days, as has the crop's popularity, making United Oilseeds the farmers' first choice for marketing their crop and providing seed and advice on growing oilseeds.
United Oilseeds uses its collective strength to negotiate on behalf of its members on marketing, seeds, and legislation, ensuring its members are fully represented in the industry, and receive guidance on key issues affecting their crops.
