GEN-I’s transparent billing deemed one of the best practices in Europe

GEN-I is aware how important transparent electricity and natural gas bills are for our customers. We are proud of the fact that our commitment in this regard was recognized by the European Consumer Organization, BEUC. As part of the ‘Energy Billing: Landscape Report and Summary of Good Practice’ survey, GEN-I’s bill for Affordable Electricity and Affordable Natural Gas was selected out of 300 bills from 10 European countries as an example of good practice in the designing of a consumer-friendly bill and as an example for other market players. In terms of recommendations, the survey took into account the basic objective and content of a bill, understandability, call for payment, usefulness, design solutions and the responsiveness of customers following the receipt of a bill.
