Flying taxis, animal pharmaceuticals and electric heaters are just some of the sectors which have helped some of Northern Ireland’s richest people make The Sunday Times Rich List.
Leading the pack is Belfast-born founder of OVO energy Stephen Fitzpatrick who has become a billionaire with an estimate fortune of £1.34 billion, a jump of £665 million on last year.
A serial entrepreneur and now living in England, Mr Fitzpatrick co-founded OVO with his wife Sophie in 2009, building the business as a disruptor in the highly competitive energy market to become one of the biggest suppliers of gas and electricity to the domestic market.
