The price of energy bills could change more frequently under new plans from Ofgem.
The energy regulator's plans would see the price cap on household energy bills reviewed every three months, taking the total to four a year. Ofgem said on Monday it might insert two new reviews a year, one in January and another in July.
After a consultation, Ofgem hopes that the changes could come into force from October. This would mean the first change under the new system would be made in January 2023.
