According to the Sunday Times Rich List 2023, he is the fifth-richest person in the United Kingdom, with an estimated family net worth of £23 billion.

[15] In 2015 Dyson spoke at the opening of a retrospective exhibition of de Sausmarez's work at the University of Leeds, speaking of the great influence the artist and former principal had on him and his career.

His first original invention, the Ballbarrow, was a modified version of a wheelbarrow using a ball instead of a wheel and was featured on the BBC's Tomorrow's World television programme.

[citation needed] In the late 1970s, Dyson had the idea of using cyclonic separation to create a vacuum cleaner that would not lose suction as it picked up dirt.

[20] Partly supported by his wife's salary as an art teacher, and after five years and about 5,127 prototypes, Dyson launched the "G-Force" cleaner in 1983.

[21] No manufacturer or distributor would handle his product in the UK, as it would have disturbed the market for replacement dust bags, so Dyson launched it in Japan through catalogue sales.

The new model featured 360° scanning and mapping for navigation, cyclonic dust separation, a custom-designed digital motor for high suction, tank treads for traction, a full-width brushroll bar, and user interface via a free iOS or Android app.

"[21] In 2000, Dyson expanded his appliance range to include a washing machine called the ContraRotator, which had two rotating drums moving in opposite directions.

[38] The then Prime Minister David Cameron, said: "Dyson is a great British success story and the expansion of the Malmesbury campus will create thousands of new jobs, providing a real boost to the local economy and financial security for more hardworking families.

Investment on this scale shows confidence in our long-term economic plan to back business, create more jobs and secure a brighter future for Britain".

[39] In March 2016, Dyson announced a second new multimillion-pound research and development centre on a 517-acre (209 ha) former Ministry of Defence (MoD) site at Hullavington, Wiltshire.

Dyson said: "After 25 years of UK growth, and continuing expansion globally, we are fast outgrowing our Malmesbury Campus.

[40] In September 2017, Dyson announced plans to produce an electric vehicle, aiming to be launched in 2020, investing £2 billion of his own money.

[9] Dyson has several times accused Chinese spies and students of copying technological and scientific secrets from the UK through the planting of software bugs and by infiltrating British industries, institutions, and universities after they left.

The creation of the additional UK tax-deductible interest payments relied on deals with the Luxembourg tax authorities revealed in the 2014 Lux Leaks.

[57] In the previous three years, Dyson had featured at 6th, 4th and 3rd in the Sunday Times Tax List, with the newspaper estimating a total contribution of £345.8 million to the UK exchequer.

[58][59][60] In 1998, Dyson was one of the chairmen and chief executives of 20 FTSE 100 companies who signed a statement published in The Financial Times calling on the government for early British membership of the Eurozone.

[73] After it became public in January 2019 that Dyson's company was to move its headquarters from Malmesbury to Singapore, he was accused of hypocrisy regarding his campaign for Brexit.

[76] Dyson criticised Prime Minister Rishi Sunak in January 2023 for what he called "ever higher tax bills" for corporations.

[86] In March 2015, the foundation gave £12 million to Imperial College London to allow the purchase of a Post Office building in Exhibition Road from the Science Museum.

[107] In 2003, Dyson paid £15 million[citation needed] for Dodington Park,[108] a 300-acre (1.2 km2) Georgian estate in South Gloucestershire close to Chipping Sodbury.

The Dyson company have been the title sponsors of the club since 2014, with Bath Rugby being the first sports team officially backed by the firm.

[114] As a result of this, Dyson are the main brand on all club kit and are the naming rights holders of the East Stand at the Rec.

[115] In July 2019, Dyson spent £43 million on a 21,108-square-foot (1,961.0 m2) triplex flat at the top of the Guoco Tower, the tallest building in Singapore.

[120] Dyson has also invested heavily in buying agricultural land in Lincolnshire, Oxfordshire, and Gloucestershire, and by 2014 was one of the biggest landowners in the UK.

[121] Dyson is the beneficial owner of Weybourne Holdings Pte, a Singapore-based business that (as of 2023[update]) owns 31 UK properties, worth at least £287 million.
