Heat Trust gathers twice-yearly monitoring data from each of our Registered Participants on complaints numbers and type, interruptions and their causes, customers on priority services/ vulnerability registers and more. We are in a unique position as the only independent organisation to gather and publish this data annually. Our annual reports also include updates on Heat Trust’s activities, changes in the heat network market, and developments in regulation. Please see below for all of our annual reports.
