Mark Pears and family

Piccadilly power eaterie The Wolseley is part-owned by the three Pears brothers, led by Mark, 44, who is managing director of the London-based William Pears Family Holdings. There are at least 44 other businesses, which showed profits of £110m and net assets of more than £650m in 2005-06. We value the family’s stake in property company Telereal at £300m. Holdings outside Telereal are easily worth £1.1 billion and we raise our valuation of the family to £1.5 billion after tax.
