Besides listing members of the landed gentry, he added lawyers as well as powerbrokers in showbusiness and the media, arguing that they were equally prominent. In 1999, he became the Baron of Bombie, Kirkcudbrightshire, Scotland after he purchased the title from Sir David Hope-Dunbar of the Hope-Dunbar baronets and the defunct insurance firmAllied Dunbar.

In 2014, they extended their commitment up to 2020. Additionally, they have made charitable gifts to Opera North, the Buxton Festival, and the East Riding of Yorkshire Choir in England. The Pettman Junior Academy was established in 2005 in collaboration with the University of Canterbury.

In 2011, they agreed to donate £1 million over the next five years to the Pettman Junior Academy at the University of Canterbury in Christchurch, New Zealand.
