Pass Through Charges

Pass Through Charges are items which may appear on a customer’s energy bill, covering the cost, if relevant, of any third party services involved in the energy supply chain.

Peak Demand

Peak Demand refers to the maximum demand for electricity placed on the National Grid on any given day or over any time period.

Percentage Day

Refers to the percentage of electricity used during the daytime versus the night-time. Suppliers use this information to generate and assign the customer profile.

Power Factor

Used to gauge how efficiently electricity is utilised across a site, particularly when using certain types of industrial equipment and machinery — which could reduce the capacity of the local network to supply power. DNOs often apply Power Factor charges to large consumers who use electricity inefficiently.
