Meet the UK's richest millennial, the Duke of Westminster, who's worth more than $12 billion

Grosvenor is the 11th richest person in the UK, according to the Times of London's 2023 Rich List, which was released in May. It also named him the country's richest person under the age of 35.

In 2022, he was ranked 12th on the Rich List. In the year since, his wealth has increased from £9.726 billion to £9.878 billion, according to the Times.

Gerald Cavendish Grosvenor, the 6th Duke and a close friend of the Queen and then-Prince Charles, was 64 when he died of a heart attack on August 9, 2016. At the time, he was the 114th wealthiest person in the world, with a fortune of around £9 billion, or $11.4 billion, according to Forbes.

Hugh Grosvenor inherited his father's billions, as well as his estates in the wealthy London neighborhoods of Belgravia and Mayfair, and the ancestral home in Cheshire, Eaton Hall. As much of the wealth was passed down through family trusts, he did not have to pay billions in inheritance taxes, The Guardian reported.

The Grosvenor family's website says, "As Grosvenor family members, who are the beneficiaries of the trusts, are all UK residents – as their predecessors have been for nearly 1,000 years – they pay UK taxes in the same way as the rest of the UK population, while being entitled to the same exemptions."

The family can trace its lineage back almost 1,000 years. Much of the family's fortune comes from a 17th-century dowry given to a Sir Thomas Grosvenor, which included 500 acres of land just outside of London, Bloomberg reported.

The 1st Duke of Westminster was born at Eaton Hall, which remains the family seat, and served as a member of parliament before joining the House of Lords. His wife was a friend of Queen Victoria's, according to Westminster Abbey, and Prime Minister William Gladstone honored him with the title in 1874.

The duke's oldest son preceded him in death, and the title passed to his grandson, Hugh Richard Arthur Grosvenor. Throughout history, the title has passed on to male heirs including cousins, brothers, and in the case of Hugh Grosvenor, father to son.

Grosvenor's mother, Natalia, is a direct descendant of the Russian poet Alexander Pushkin and King George II, the London Evening Standard reported.

Primogeniture, which was established in the 11th century in England, determines the first-born son inherits power and wealth so, despite having two older sisters, Grosvenor inherited the Westminster title and estate on his father's death. His sisters, however, did receive trust funds.

The photograph taken at his oldest sister Lady Tamara Grosvenor's wedding to Edward van Cutsem in 2004 indicates the four Grosvenor siblings.

Circled left is his younger sister, Lady Viola, who is now 30. She runs an art-therapy business, according to the Times of London, and is married to Dragoon Guards officer Angus Roberts, Tatler reported.

Second from left is Lady Edwina, who is now 41 and a prison-reform campaigner. She is married to a British TV presenter, Dan Snow.

Lady Tamara, 42, remains married to van Cutsem, who is a close friend of Prince William.

Grosvenor is circled right. He was 13 at the time of his sister's 2004 wedding.

Grosvenor attended a local state primary school before going to a private school, Ellesmere College in Shropshire, for high school.

"His mum, Tally, was keen on the children having a more normal upbringing, so almost consciously didn't want them to go to all those Eton, Harrow sort of places and risk turning into that arrogant, entitled type of person," a friend told The Telegraph in April.

His father said in an interview with the Independent in 1992, "He's a lucky boy to be given all the material things in life, but he'll need to be robust mentally to survive. There are many pitfalls when one inherits such an enormous amount of money, especially in adolescence.

"He's been born with the longest silver spoon anyone can have, but he can't go through life sucking on it. He has to put back what he has been given."

Grosvenor studied countryside management at Newcastle University, according to the Times.

In 2012, he celebrated his 21st birthday with a "black tie and neon" party for 800 guests — including Prince Harry — at the family estate, Eaton Hall, in Cheshire. According to attendees, there were fireworks, champagne, and performances from English comedian Michael McIntyre and hip-hop band Rizzle Kicks.

In a speech at the party, his father said Grosvenor was the first heir for 133 years to be both born at Eaton Hall and to celebrate their 21st birthday there, Cheshire Live reported. The last person before him was the second duke, who was born in 1879.

The Grosvenors have remained closely tied to the royal family. Then-Prince Charles, now King Charles, asked Grosvenor's father, Gerald, to be a mentor to Prince William when he was young.

In turn, William asked Hugh Grosvenor to be godfather to his own son, Prince George. Grosvenor was 22 when Prince George was christened at St. James's Palace in London in 2013. He was one of seven godparents: Among the others are King Charles' niece — and Prince William's cousin — Zara Tindall, and Edward van Cutsem, brother to Grosvenor's brother-in-law William van Cutsem.

Prince William and Prince Harry have also reportedly spent time at Grosvenor's hunting estate in Spain.

And in June 2018, the duke handed over the then-newly built Defence and National Rehabilitation Centre in Leeds to the nation, in an event also attended by Prince William.

The estate includes the exclusive London neighborhoods of Mayfair and Belgravia. The centerpiece is Eaton Square, an elongated square of elegant townhouses overlooking private gardens and close to Buckingham Palace.

The Grosvenor Group's property empire also includes buildings in cities across the world, such as San Francisco and Washington, DC, in the US, and Stockholm, Tokyo, and Beijing. The buildings range from luxury retail spaces and shopping districts to offices and residences.

He also oversees the family investment office, which manages rural estates across the UK and abroad, and employs 450 people. The Grosvenor Group also invests in other industries, such as food and agricultural technology.

He oversees the Grosvenor Group's charity work and "is firmly committed to using his position and the resources in his care to make a positive contribution to society, just as previous generations of his family have done before him," according to the Grosvenor website.

The duke also serves as chair of trustees for the Westminster Group, his family's charitable foundation, which provides grants to organizations supporting and working with at-risk children.

"We want young people to thrive, we want to give them the opportunities," he said in a video for the foundation. "So many of us are lucky enough to have opportunities in life which we often take for granted but so many aren't."

The Defence and National Rehabilitation Centre in Leeds, a rehabilitation center for injured troops that opened in 2018, was an initiative led by Grosvenor's father, according to a press release. The family has personally gifted £105 million, or about $133 million, to the project, according to the Grosvenor website.

In 2020, the duke also made headlines for donating over $15.6 million to charities to help the United Kingdom fight the coronavirus. Among the donations, he pledged $6.2 million to the NHS to help healthcare workers and their families, as well as $3.8 million for medical research, CNN reported.

Eaton Estate in the Cheshire countryside has been home to the Grosvenor family since the 1400s. It includes hundreds of residential, commercial, and agricultural properties, which can be rented.

But at the center of the estate is Eaton Hall, the family's home on the banks of the River Dee, just south of Chester. The property, which is surrounded by expansive, well-manicured gardens, has gone through various iterations, including demolitions and rebuilds. The current main home was built in 1967, and it now has a French-châteaux-style façade.

In nearby Chester is the Grosvenor Museum, which houses some of the family's collection of art, which was mostly collected during the late 18th and early 19th century. Their collection includes pieces by Velázquez, Rembrandt, and Lucian Freud.

According to the Times, "a substantial amount of his time" goes towards skeet shooting, in which participants shoot clay targets that move through the air. He represents the national team at competitions, according to his website.

"Outside of his business and philanthropic work, the Duke represents Team GB at Olympic Skeet Shooting competitions overseas and in the UK and continues to pursue his ambitions as an elite sportsman," the Grosvenor website says.

He competes under the name Hugh Westminster, according to his ISSF Sports profile, and has so far competed internationally in Doha and Cairo this year. In April, he placed third at an event at the National Clay Shooting Centre, British Shooting shared on Instagram, with a photo of him on the podium.

A friend who spoke to the Telegraph called Grosvenor "a stable pair of hands."

He proposed to Henson, 30, at Eaton Hall, People reported in April.

"Members of both their families are absolutely delighted with the news," according to a press release.

They met through friends two years ago, The Times of London reported. She works as a senior account manager at Belazu, which imports responsibly sourced olive oil and other Mediterranean and Middle Eastern ingredients.
