Energy Price Cap
The ofgem price cap sets the maximum standing charge and unit rate that energy suppliers can charge on a standard variable tariff (SVT). It doesn't cap your total bill - what you pay depends on how much energy you use, how you pay for your energy, where you live and your meter type.

For Customers with Economy 7 Meters (E7)
For customers with an Economy 7 meter, which has a separate day and night unit rate, suppliers can price the day and night differently within the Ofgem price cap rules. In order to conform, a split of usage is used across Day and Night, typically this is 58% on the day and 42% on the night. The maximum weighting (1 rate) is shown in the table. This is the maximum a supplier can change, anything underneath this conforms to the price cap. Please see worked example below:
In order to calculate a suppliers specific day and night rates, use the following formula:
- (Standing charge) x 365 = (Total Standing Charge)
- (Day rate) x 2,436 kWh's (58%) = (Day Total) Example 36.740p x 2,436 = £894.99
- (Night Rate) x 1,764 kWh's (42%) = (Night Total) Example 13.280p x 1,764 = £234.26
- (Day Total) + (Night Total) / 4200 kWh's = (E7 Weighted Unit Rate) Example £894.99 + £234.26 / 4200 = 26.887
