The Cabinet Office has appointed Greg Jackson, the chief executive of renewable energy supplier Octopus Energy Group, as a non-executive board member.

Jackson has been appointed as a non-executive member of the Cabinet Office board for three years. His term started on 21 July and will conclude in 2028.

An entrepreneur and angel investor, Jackson founded Octopus Energy Group in 2015 and has been chief exec at the company for 10 years now. His previous roles include co-founder and chairman of Consultant Connect, a telemedicine provider; and non-executive director at Zopa, a British online bank.

He is also an honorary fellow at Pembroke College Cambridge and holds an honorary doctorate at the University of Teesside.

The board provides strategic leadership for the department, and consists of Cabinet Office ministers, senior civil servants, and non-executives from outside government.

Non-execs are responsible for providing support and challenge to the department’s ministers and senior officials on the delivery of key policies and programmes.

Jackson joins current non-execs John Fallon, a former chief executive of education multinational Pearson, who became the Cabinet Office's lead non-executive board member in May, and Lisa Tremble, chief people, corporate affairs and sustainability officer at British Airways, who joined as a non-executive board member in the same month. 

The appointments come after seven of the Cabinet Office's NEDs had their appointments terminated before the end of their contract when Labour won power in July 2024.
