With "Duncan's Super Ices," he set out to become the king of the 99 and eventually sold the business for £28,000, founding a nursing home business instead.
He sold his nursing home business for £46 million in 1996. Duncan quickly diversified into the fitness market and, just over a decade later, now operates Bannatyne’s Health Clubs, the largest independent chain in the UK. His Bannatyne Group also has interests in hotels, bars and a chain of luxury health and wellbeing spas.
Duncan holds an OBE and was awarded an honorary Doctorate of Science (D.Sc.) by Glasgow Caledonian University in July 2006 for services to business and charity. He was also awarded a Doctorate of Business Administration (DBA) from the University of Teesside in February 2009.
He operates the Bannatyne Charitable Trust, which supports worthwhile causes.
