There are 52 millionaires in the South West, according to the Sunday Times Rich List 2014.
The list, published yesterday, puts the combines wealth of the region's super-wealthy at £18,511million.
The richest man in the region is inventor and entrepreneur Sir James Dyson with a fortune of £3billion.
Range owner Chris Dawson comes in fourth with £1.28billion - a sum which makes him the 73rd richest person in the country.
Bruce Robertson, who heads the Trago Mills chain of discount stores, shares a family fortune estimated at £118 million, £2 million more than last year, according to the list.
The first Trago Mills was opened by his late father Mike Robertson, after starting out selling goods at a discount in the early 1960s from sheds between Liskeard and Bodmin. The present huge store there was developed after highly publicised battles with planners over the years.
Further stores at Falmouth, Newton Abbot and South Wales have boosted the family fortunes and placed them as 607th in the new Sunday Times Rich List.
Britain’s wealthiest people are richer than they have ever been with a combined fortune of £518.975 billion – equivalent to a third of the nation’s Gross Domestic Product.
As the rest of the country emerges slowly from recession, The Sunday Times Rich List 2014, reveals that the 1,000 richest men and women have surged to new heights, with their combined wealth rising by 15.4% on last year’s total of £449.654 billion.
This year’s total dwarfs the £412.846 billion which the top 1,000 recorded before the 2008 financial crash.
Philip Beresford, who has compiled the list since 1989, said: “I’ve never seen such a phenomenal rise in personal wealth as the growth in the fortunes of Britain’s 1,000 richest people over the past year.”
The amount of money needed to join the list is £85m. This compares with £80m in 2008, at the height of the pre-crash boom, and is £10m up on the 2013 entry point of £75m.
To get in to the top 500 you need £190m, more than double the £80m required in 2004 and up by £30m from the £160m needed to get in the top 500 last year. “The richest people in Britain have had an astonishing year. While some may criticise them, many of these people are at the heart of the economy and their success brings more jobs and more wealth for the country,” Beresford said.
John Roberts, creator of AO.com, the household appliance internet retailer, comes into the Rich List for the first time this year with a fortune of £410m, which ranks him at 246= among Britain’s richest 1,000. He is one of five investors to benefit from the AO.com float in February, who are all new entries in The 2014 Sunday Times Rich List.
Four members of the management of King Digital Entertainment, the company behind the addictive Candy Crush Saga computer game, also join the list for the first time. They include at 238= Mel Morris, with a £430m fortune, and Riccardo Zacconi, ranked 271 and worth £354m, who is the chief executive of King. Sam and Dan Houser, the brothers who devised the controversial Grand Theft Auto computer game, are new entries with a joint fortune of £90m, ranked at 947.
Among the well-established Rich List millionaires, Jamie and Jools Oliver have seen their fortune go up by £90m to £240m, ranked 396, on the strength of the thriving restaurant chain - Jamie’s Italian, TV appearances, cookbook sales and the success of Jools’s childrenswear range.
The Queen has added £10m to her personal wealth and is now worth £330m, ranked 285. The South African insurance tycoon Douw Steyn is worth £600m, ranked 170 and up £50m, boosted by the success of the meerkat TV advertising campaign for comparethemarket.com.
