Martin Cave has been confirmed as the new chair of energy regulator Ofgem.
He will take up his position on 1 October.
Prior to taking on this role, Cave has undertaken a number of roles in government including as Economic Adviser to Ofcom between 2003 and 2006.
Secretary of State for Business, Energy and Industrial Strategy, Greg Clark said: "We are determined to see active regulators who put consumers interest at the heart of their work, the appointment of Professor Cave to lead Ofgem will ensure that.
Professor Cave has an impressive track record and is well respected for his work regulating the utility markets. I have no doubt he will use his wealth of expertise to protect consumers whilst we continue to build and upgrade our energy system to make it fit for the future."
