Centrica has named its finance director Phil Bentley as the new head of its British Gas business.
UK households are reeling from a string of utility bill rises
The 47-year-old will take over from Mark Clare who announced his departure in June this year.
The role will be a high-profile one, with Mr Bentley overseeing the bills of 16 million gas and electricity users.
Mr Clare's four-year tenure was marked by a string of inflation-busting energy bill increases, including March's 22% price rise and another this month.
The company blamed the rises on the high price of wholesale gas and energy prices, which led to British Gas turning in a loss of £143m for the six months to June, compared with a £165m profit at the same time in 2005.
However, its latest price increases - 12.4% for gas and 9.4% for electricity - drew fire from consumer groups as Mr Clare had said after March's rise that there would be no need to raise prices again this year.
