If you’re on a standard or default tariff, the Price Cap - set by energy regulator Ofgem - places a limit on the amount your provider can charge for each unit of energy and the daily standing charge. For someone with typical dual-fuel use and paying by Direct Debit, the cap is currently set at £1,690 a year. Yet this isn't the maximum you'll pay - use more and you’ll pay more, use less and you’ll pay less.

Ofgem also revise the level of the cap four times a year with changes coming in from January, April, July and October, based on suppliers' costs. To show the amount you could save by switching, Cheap Energy Club uses the most up-to-date rates of your current tariff, and bases your savings on the rates staying the same for the next year.

However, as the Cap changes every three months, you need to understand what’s expected to happen to the Price Cap over the next 12 months when deciding whether to switch. That’s why – if you’re on a capped tariff and you pay by monthly Direct Debit – we’ll let you know at the top of your comparisons results what’s predicted to happen over the next year.
