and Orbit Energy. In August 2022, Ofgem announced that the price cap would be reviewed every three months instead of every six months, in reaction to wholesale price volatility. Thus the review in October 2022 would be followed by another in January 2023. The average price cap has been set as follows: 2022: Government support for households In response to the marked increase in the default tariff cap from April 2022, on 3 February the Chancellor, Rishi Sunak, announced measures to support domestic gas and electricity customers in England, Wales and Scotland. There would be a £200 discount on energy bills, to be given in the autumn and paid back by customers in later years. In addition, from April a non-repayable £150 council tax rebate was given to households in England in tax bands A to D (estimated to be 80% of homes), and local councils received £144million to provide discretionary funding to other residents. The devolved administrations received around £715million so they could provide comparable support, and there was an expansion of the Warm Homes Discount scheme.

Comparable support would be offered to businesses, public sector organisations (under a six-month scheme running to 31 March 2023) and to households who do not pay directly for electricity or mains gas, such as those in park homes or on heat networks. The cost of this package of support was uncertain since it depended on future wholesale prices, but was estimated at over £100bn per year by the Institute for Fiscal Studies.
