2 OVO’s 2019 analysis of academic research into the effectiveness of feedback on energy consumption behaviours indicates that being able to monitor your energy usage by installing a smart meter and having access to energy insights information can lead to a reduction in energy use. The reduction in energy use results from the customer making changes to their habits by curtailing home energy use through actions such as optimising heating settings or switching lights off. The actual savings achieved will vary depending on individual energy use and the nature of changes made to a customer’s energy habits. OVO’s energy tracking is currently available for the majority of OVO customers and will be made available to all remaining customers soon.
