Ofgem wish to understand perceptions of performance against strategic priorities, regulatory performance, and establish a baseline on these metrics for Delivery and Scheme participants. Ofgem also wish to use analysis of data to identify areas where engagement methods, systems and processes could be improved for customers and stakeholders in their experience with us. Where you agree to participate in a survey we will also process your information based on your consent.
