What is on an electricity bill
The wholesale energy is often less than half of the total. The rest is network charges, policy costs such as the Renewables Obligation and Capacity Market, supplier margin and levies. Each part can be managed, and several can be reduced with the right contract structure, capacity settings and reliefs.
