Their family's company has assets in automotive, finance, oil, and other areas, with a fortune, assessed at £28.472 billion, the greatest figure ascribed to a family or individual in the Rich List's 34-year history. Prakash, Ashok, Sri, and Gopi Hinduja head the Hinduja Group, a multinational business. Trucks, lubricants, banking, and cable television are all part of their group's operations. The brothers possess a significant amount of property in London, notably the historic Old War Office building in Whitehall, which will host a Raffles Hotel.

Sri and Gopi Hinduja live in London; Prakash in Monaco; and Ashok, the eldest sibling, manages their Indian affairs from Mumbai. A court petition in the United Kingdom in June 2020 disclosed a feud between the eldest Srichand and his three younger brothers over the ownership of a Geneva bank. The Hinduja family rose to the first position from third place in last year's list of the UK's wealthiest net worth individuals, although The Sunday Times reported that "all may not be harmonious" within the dynasty. Sri Hinduja, 86, claims personal ownership of the Hinduja Bank in Switzerland, but Gopi, 82, and their other brothers allege Sri suffers from dementia.

"Money was really unimportant" when James Dyson was a child, he told the BBC. With a net worth of £23 billion, he now has plenty to spare. In the 1990s, his vacuum cleaners became famous, and he has since expanded his product line to include hairdryers, air conditioners, hand dryers, and lighting. Dyson's design and economic success added credibility to his mission to rekindle the British spirit of creativity. Against the Odds, an autobiographical narrative of his perseverance in the face of adversity was released in 1997. He was awarded a Commander of the Order of the British Empire the following year.

Dyson was asked by the Conservative Party to offer strategies to boost innovation in 2009, and he responded in March 2010 with Ingenious Britain: Making the United Kingdom the Leading High-Tech Exporter in Europe. According to The Sunday Times, his most recent innovation, the Dyson Zone, is a pair of over-ear noise-canceling headphones with an air-purifying mask "that gives the wearer more than a passing resemblance to a cyberman."
