The document below sets out the level of the prepayment meter price cap, which will apply for the period 1 April 2019 to 30 September 2019. We have also provided two spreadsheets which show, for the restricted charging period, how we have:
- calculated the network charge component of the cap
- used the network charge and other inputs to get the final level of the cap
These spreadsheets are updated versions of the illustrative price cap model and network cost calculations spreadsheet previously published by the CMA.
The levels of the cap are expressed in pounds, excluding VAT. They are described for two levels of consumption for a customer that:
- does not use any energy
- uses an assumed amount of energy ‘m’
We get the level of the cap for all other possible consumption levels using these two values. Note that the levels of consumption ‘m’ are not the same as the current typical domestic consumption values, which are commonly used to calculate a typical annual bill.
Guidance for energy customers
If you are an energy customer trying to find out your capped tariff price, please contact your energy supplier. You can find their contact information on an energy bill, or see Who is my energy supplier? You can also find answers to frequently asked questions on our consumer FAQ page.
Further guidance for suppliers
Suppliers looking for additional guidance on how to use these values to ensure that their prepayment tariffs comply with the cap should refer to the document on our page prepayment meter price cap - reporting template and FAQ.
Default tariff cap
The default tariff cap came into effect on 1 January 2019, bringing further price protection for all customers on poor value standard variable and default tariffs. More information can be found on our industry page Default Tariff Cap.
