The document below sets out the level of the Prepayment Meter Price Cap, which will apply for the period 1 April 2020 to 30 September 2020.
We calculate the level of the Prepayment Meter Price Cap following the Competition and Markets Authority’s (CMA) methodology. In July 2019, the CMA revised the methodology, to better reflect the costs incurred in delivering energy services to prepayment customers. From 1 October 2019, the Prepayment Meter Price Cap methodology aligns more closely with our methodology for the Default Tariff Price Cap.
Alongside the cap levels we have also published the updated versions of the models / annexes.
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 calculate the level of the cap for all other possible consumption levels using these two values. Note that the levels of consumption ‘m’ are 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.
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.
