Kingsbury moves across from private equity firm Hudson Clean Energy Partners and joins chair Lord Smith of Kelvin and deputy chair Sir Adrian Montague who were appointed in May.
Six non-executive directors have also been selected: Professor Dame Julia King, Fred Maroudas, Tom Murley, David Nish, Isobel Sharp and Tessa Tennant. Between them they have experience in universities, business, investment funds, equity finance and the low carbon sector.
Cable said: “I am delighted that we have been able to appoint people of such high calibre to the Board of the UK Green Investment Bank. I have every confidence that the team will build on the good progress already made, leading the Bank into full operation and developing a truly ground breaking institution.”
The CEO and non-executive directors will take up their posts in late October.
Kingsbury said he was “delighted” by the opportunity, adding: “The Bank has the important and exciting principal task of allocating capital to projects which can both enhance economic competitiveness and provide leadership in environmental business performance.”
