Wincott edited the Investors Chronicle for twenty-one years and was a columnist for the Financial Times. He was awarded a CBE in 1963 and wrote pamphlets for the Institute of Economic Affairs, a free-market think-tank based in Westminster, London.
According to one contemporary, Wincott had an "enormous influence on City thinking"; it was Wincott who invented the character Solomon Binding in his column as a joke on the numerous "solemn and binding" pledges made at TUC Conferences. The Conservative politician John Biffen has claimed: "If I had a mentor, it was probably Harold Wincott".
The Wincott Foundation was established in 1970 in honour of Harold Wincott's achievements, with the purpose of supporting and encouraging high quality economic, financial and business journalism. The Foundation sponsors annual awards for economic, financial and business journalism in the UK, and provides fellowships and scholarships to journalists.</ref>
