Our research shows that of the top 100; 49 inherited their wealth, 34 are entrepreneurs, eight happen to have climbed the corporate ladder, while nine have started their own successful business in a similar field after leaving a high-powered job.
What a difference a decade makes
Top of the list are the Reuben brothers. The property and metal trading tycoons are self-made billionaires having moved from Mumbai to London in the 1950s and made their fortune investing in Russian metals market during the fall of the Soviet Union in the 1990s.
They can technically be classed as entrepreneurs, although they have not created a unique product or different business, as most of their money is made from trading and property.
The makeup of the list has barely changed in the past decade. In 2006 the Reuben brothers were the eighth richest in the UK with steel tycoon Lakshmi Mittal at number one. His wealth has fallen from 14.8bn to 7bn in a decade he is now the eleventh richest in the UK.
The main difference has been that those at the top, particularly with inherited wealth, have seen their value grow.
The list does slightly reflect the changes in dominant industries. Retailer Philip Green was the fifth richest in 2006 at 4.9bn, he is now the 29th richest, worth 3.2bn.
You also now need to be richer to get a mention in 2006 you needed 60m to get into the rich list, now you need 103m.
Of the top ten, six have inherited their wealth, such as the Hinduja Brothers. Now worth 13bn and the second richest in the UK, their business, which invests in industries such as property, oil and healthcare, started as part of a family empire in 1914.
