W ill Adderley is a British billionaire who is the deputy chairman and a major shareholder of the home furnishings retailer Dunelm Group. The company was founded by his parents, Bill and Jean Adderley, who started the business in 1979 as a small market stall selling curtains. They built Dunelm into one of the largest and most successful homewares retailers in the United Kingdom, famous for its wide selection and affordable prices.

Will joined the family business and eventually took over as CEO, a role he held for many years, overseeing the company's continued growth and its successful IPO on the London Stock Exchange. He has since stepped back from the CEO role and now serves as the deputy chairman, with his father, Bill, serving as chairman emeritus. The family's vast fortune is derived from their large controlling stake in the publicly traded retail empire they built from a market stall.
