Ofgem reviews the domestic energy price cap on a quarterly cycle. New cap periods normally begin on 1 January, 1 April, 1 July and 1 October. The cap affects standard variable and default tariffs, but actual bills still depend on usage, tariff type, standing charges and supplier rules. Check Ofgem and your supplier before making decisions.
