From January 2025, each consumer’s power level will be shown on their bill. Ahead of application, these power levels will initially be allocated on the basis of consumption history, with the aim of identifying the optimal category from a financial perspective. Once applied, the categorisation will be checked on a monthly basis by an automated mechanism. In some rather exceptional cases, a customer’s request to change categories may be justified, particularly where there have been significant changes in consumption behaviour, such as when installing an electric vehicle charging point or a heat pump.
