Your Annual Statement usage is calculated based on the number of kWh’s you have used over the last year, your current tariff and any additional charges such as VAT or site visit charges. The estimated cost of their supply for the next 12 months. This is based on estimated consumption figures. This may appear inflated as it will incorporate the price increase and potential upcoming tariff end that will assume the tariff will default to pioneer. We may use estimated meter readings to calculate your usage if no customer meter reading have been provided. We ask that you submit your most recent meter reading to us each month through your online account. We are then able to provide you with an actual bill. Submitting your meter reads is the easiest way to ensure your bills, Direct Debit Reviews and Annual Statements are accurate.
