The energy price cap will increase from the current £1,971 to £3,549 from October 1, regulator Ofgem has announced.
The energy regulator currently updates its price cap twice a year - in April and October. But now, the regulators will review the cap every January, April, July and October.
Ofgem says the idea of reviewing its price cap more often is so energy companies can provide more accurate pricing for customers. It means millions of households who are on a standard variable tariff will see more frequent changes to their energy bills.
