The boss of British Gas has warned households across the UK that the energy crisis may last for another two years.
Speaking to the BBC, Centrica chief executive Chris O'Shea, said "the market suggests" high gas prices will continue "for the next 18 months to two years".
He said the high demand for gas was partly being driven by a move away from coal and oil.
Mr O'Shea explained: “As we move towards net zero, gas is a big transition fuel and so as you turn off coal-fired power stations in other countries, there isn't an abundance of gas that you can just turn on quickly."
But he also threw cold water on the idea of boosting supply from the North Sea as a domestic solution to the crisis.

"I'm not sure an increase in UK supply would have brought the price down from £3 a therm, as it was in December, from 50p as it was a year ago," he said.
"We bring gas in from the United States, from Norway, from Europe, from Qatar, from other places. So we're not in a position to simply have the UK as an isolated energy market. We are part of a global market."
Centrica is the largest supplier of gas to domestic customers in the UK and one of the largest suppliers of electricity, operating under the trading names Scottish Gas in Scotland and British Gas in England, Wales and Northern Ireland.
It also owns Bord Gáis Energy in Ireland.
Mr O'Shea's comments come after industry leaders warned a taxpayer-backed support package for energy-intensive businesses hit by the surge in gas prices may be no more than a "flimsy sticking plaster".
Prime Minister Boris Johnson is reportedly backing a plan being developed by Business Secretary Kwasi Kwarteng for state loans to firms threatened with closure over the winter.
The move follows an extraordinary Whitehall turf war between Mr Kwarteng and Chancellor Rishi Sunak, which broke out over the weekend, with the Treasury denying there any plans for the UK Government to act.
Under proposed measures, a VAT cut is unlikely to go ahead but an extension of the warm home discount could be pushed forward to help 800,000 more households.
