The Prepayment Meter Price Cap came into force on 1 April 2017. The cap is temporary, and applies to prepayment meter customers on a non-fixed deal and without an interoperable smart meter. Suppliers can price to the level of the cap or below it, but cannot charge more.
A separate price cap applies to customers on a standard variable or default energy tariff. See Default Tariff Price Cap.
Before the Default Tariff price cap applied on 1 January 2019, and from February 2018, customers on a standard variable or default energy tariff and who received the government’s Warm Home Discount were price protected at the level of the prepayment meter price cap (sometimes referred to as the ‘safeguard tariff’).
When is the prepayment meter cap updated?
Ofgem adjusts the level of the cap twice a year – in February and August to apply in April and October respectively – to reflect the estimated costs of supplying electricity and gas to homes in the next six-month summer or winter period.
In August we will publish the details for the six-month winter prepayment price cap period which begins on 1 October.Industry guidance on applying the prepayment price cap
