The Default Tariff Cap came into force on 1 January 2019 – a temporary cap on standard variable tariffs and fixed term default tariffs. In August 2022, Ofgem announced the Default Tariff Cap will be updated on a quarterly basis rather than every six months. In accordance with the licence requirements, we will now run an update process four times a year to ensure the Default Tariff Cap reflects changes in the cost of supplying energy more quickly.
On 25 May 2023, we published the cap levels that will come into force for charge restriction period (“cap period”) 10b from 1 July 2023 - 30 September 2023. The updated versions of the underlying models have also been published.
You can view all historical information and publications relating to the design of the cap on our policy pages for the default tariff cap.
