The Vocational Rich List tracks the fortunes of businessmen and women who started their career with a vocational qualification or training course and is now in its sixth year.
Of hospitality's representatives, Michelin-starred Gordon Ramsay comes highest at 50 on the list with a personal fortune of £50m. Snapping at his heels in 55th place is Jamie Oliver, worth £40m at the age of 33.
Robyn Jones, chief executive of contract caterer Charlton House, is 74th on the rich list and worth £20m, while chef and cookery writer Delia Smith comes 85th with a personal fortune of £15m.
Gary Rhodes, who picked up a Michelin star for Rhodes W1, is 92nd on the list with just £10m to his name.
Bob Coates, managing director at City & Guilds, said: "It's encouraging to see that many of the entrepreneurs who started their careers with a catering qualification continue to flourish."
