The Duke and his family are estimated to be worth £10.1 billion (US$13 billion), according to the Sunday Times Rich List in May 2019. He is the world’s richest person aged under 30.

Upon his father’s death, in August 2016, as well as the peerages, he inherited a wealth then estimated at £9 billion, with considerable trust funds for his sisters. This wealth is held in a trust, of which Grosvenor is a beneficial owner but not the legal owner—an arrangement that received considerable press attention, owing to the inheritance tax exemption it confers.

After university, Grosvenor (at the time Earl Grosvenor) worked in estate management at Wheatsheaf Investment from 2013 to 2014, and the Grosvenor Group from 2014 to 2015, before becoming Accounts Manager at Bio-bean, a green energy company, in January 2016.

Little is publicly known about Grosvenor’s personal life, as a result of his family’s efforts to maintain his privacy. However, in October 2013, he was named a godfather to Prince George of Cambridge.

From 2011 to 2013, he studied countryside management at Newcastle University, graduating with a Bachelor of Science degree with upper second-class honours.

Grosvenor and his sisters were educated at a local state primary school, followed by a small private day school, Mostyn House School, near the family home of Eaton Hall, Cheshire. He then attended Ellesmere College, Shropshire, from 2000 to 2009. At Ellesmere, Grosvenor served as a School Prefect, Captain of Meynell House and Captain of the First XI Football Team in his final year. He was awarded Full Colours in Football, and, as a member of the School’s Combined Cadet Force, he obtained a BTEC First Diploma in Public Services with Distinction.

Hugh Richard Louis Grosvenor, 7th Duke of Westminster (born 29 January 1991), styled as Earl Grosvenor until August 2016, is a British aristocrat, billionaire, businessman, and owner of Grosvenor Group. He became Duke of Westminster on 9 August 2016, on the death of his father Gerald Grosvenor.

Hugh Richard Louis Grosvenor is the third child and only son of Gerald Grosvenor, 6th Duke of Westminster, and his wife Natalia (née Phillips). Through his mother, he is descended from the Romanov imperial family of Russia and the Russian writer Alexander Pushkin, as well as from the latter’s great-grandfather – African tribal chief turned Russian nobleman Abram Petrovich Hannibal. He was baptised into the Church of England on 23 June 1991. His sisters include Lady Edwina Grosvenor, a prison reformer and philanthropist.
